Detailed Description

The technical solution of the present invention will be further described with reference to the following embodiments.

A preparation method of the ceramic tile for repelling cockroaches comprises the following steps:

step (1): adding fluorescent powder into the glue, and uniformly stirring to obtain a fluorescent paste body;

step (2): adding the fluorescent paste into the ultra-clean and bright A liquid, and uniformly dispersing to obtain the fluorescent ultra-clean and bright A liquid for later use;

and (3): applying far infrared glaze on the surface of a brick blank, forming a far infrared glaze layer on the surface of the brick blank, and firing to obtain a far infrared ceramic tile, wherein the far infrared glaze is used as a ground glaze and consists of a base glaze and a far infrared material, and the far infrared material comprises, by mass, 0.5-5% of mullite, 3-20% of zirconium silicate, 0.1-2% of yttrium oxide and 5-10% of titanium oxide;

and (4): after the far infrared ceramic tile is softly polished, a fluorescent super-clean bright A liquid is applied to the surface of the far infrared ceramic tile according to a super-clean bright process, and the cockroach repelling ceramic tile is obtained.

The use of ceramic tile in public space and home space is more and more extensive, however, the ceramic tile of the overwhelming majority only possesses the decoration function, at present, how to combine together the function of repelling the cockroach with the ceramic tile organic, has become the very popular research subject in the ceramic tile field, though, some ceramic tiles that can repel the cockroach have appeared on the market at present, but these ceramic tiles that can repel the cockroach of present can be very weak to the repellent effect of cockroach, are difficult to satisfy the requirement of people to the repellent effect of ceramic tile.

Because, the cockroach likes the humid living environment of shade, have negative phototaxis, can send out light and by its perception after certain object, the cockroach then is reluctant to be close to, this technical scheme's the cockroach ceramic tile of keeping away that keeps away utilizes the cockroach to have this characteristics of negative phototaxis, it is compound to increase far infrared material and phosphor powder on the ceramic tile, make the ceramic tile send far infrared light and fluorescence, it will be reluctant to be close to when the cockroach perception to keep away far infrared light and fluorescence that the cockroach ceramic tile sent, and produce and dodge, thereby reach the purpose of keeping away the cockroach.

Specifically, according to the technical scheme, the far infrared material is added into the base glaze to prepare the far infrared glaze, the far infrared glaze is used as the ground glaze and is sprayed on the surface of a green brick to apply the far infrared glaze, and a far infrared glaze layer is formed on the surface of the green brick, so that the cockroach repelling ceramic tile can emit far infrared light, and the cockroach repelling purpose is achieved. In the technical scheme, the raw materials of the far infrared material comprise, by mass percentage (the mass percentage refers to the percentage of the raw materials of various far infrared materials in the total mass of the base glaze), 0.5-5% of mullite, 3-20% of zirconium silicate, 0.1-2% of yttrium oxide and 5-10% of titanium oxide, the infrared radiation performance of the far infrared material is mainly generated due to dipole moment change caused by particle vibration in a far infrared band range, according to the selection rule of symmetry, the lower the symmetry of the particles during vibration, the larger the change of the dipole moment, the stronger the infrared radiation performance, so that good far infrared performance is obtained, and the main factors for reducing the symmetry of the particle vibration are lattice distortion defects and positive contribution of the existence of impurity ions to the improvement of emissivity. This technical scheme increases the crystal that mullite and titanium oxide can generate more easily and take the defect in far infrared material to reduce particle vibration symmetry, make the change of dipole moment just bigger, thereby make the infrared radiation nature of keeping away the cockroach ceramic tile stronger, thereby effectively improve the effect of keeping away to the cockroach, the far infrared material among this technical scheme uses the raw material completely in addition, need not to calcine the preliminary treatment with the ball-milling to far infrared material, can practice thrift the cost.

Particularly, mullite, zirconium silicate and titanium oxide in the far infrared material in the technical scheme are main high-emissivity far infrared materials, and yttrium oxide plays a role in catalytic activation. The mullite is a crystal with an untight structure, the yttrium oxide is a transition metal oxide, and the yttrium oxide can be filled in the mullite to cause lattice distortion and improve the infrared radiance; most of electrons generated by the titanium oxide (and titanium dioxide) are captured by the outer layer valence electron band of the yttrium oxide, so that more holes are generated, and the infrared radiance is improved; zirconium silicate generates ZrO at high temperature in an yttrium oxide and ceramic silicate system₂ZrO of₂Has high emissivity because of ZrO₂The crystal has strong elastic displacement polarization (including electronic displacement polarization and ion displacement polarization of ions) and large dipole moment variation, so that the far infrared radiation absorption is strong, and Zr⁴⁺Radius ratio of Si⁴⁺Radius of (1), Al³⁺Radius of (2) and Ti⁴⁺All have large radii, and Zr⁴⁺Alpha of (A)_iLarge so that ZrO₂The ion displacement polarization ability in the crystal is strong, the dipole moment change is large, so the far infrared radiation absorption is strong. At the same time Y₂O₃And ZrO₂The electrovalence and the radius are different, when the solid solution is formed, the lattice distortion is easily caused, the symmetry of lattice vibration can be reduced, the activity of lattice vibration is improved, and the far infrared radiation emissivity of the material is improved, so that the mullite, the zirconium silicate, the titanium oxide and the yttrium oxide are mutually influenced and mutually promoted in the technical scheme, and the mullite, the zirconium silicate, the titanium oxide and the yttrium oxide are compounded to ensure that the mullite, the zirconium silicate, the titanium oxide and the yttrium oxide are mutually influenced and mutually promotedWith the effect that can effectively improve and keep away cockroach ceramic tile transmission far infrared to effectively improve this technical scheme's the cockroach effect of keeping away cockroach ceramic tile.

Further, too much mullite, silicic acid, yttrium oxide and titanium oxide can cause too high material cost, too much zirconium silicate can cause too high radioactivity of ceramic tiles and other side effects, and too little zirconium silicate can cause less synthesis of far infrared materials and influence the overall far infrared emissivity of the cockroach-repelling ceramic tiles.

Further, in the technical scheme, the base glaze in the far-infrared glaze is the existing ground glaze of the glazed brick, and in one embodiment of the invention, the chemical composition of the base glaze comprises SiO in percentage by mass₂：50％-60％、Al₂O₃：25％-35％、(CaO+MgO)：1.5％-3％、(Na₂O+K2O)：4％-6％、(Fe₂O₃+Ti2O)≤0.25％，ZrO₂：5％-7％。

It is worth to be noted that, because the far infrared glaze needs to be subjected to solid-phase eutectic melting and doping at a high temperature of 1200 ℃, more defective crystals can be generated, so that the crystals are asymmetric, and the far infrared radiation performance is enhanced, therefore, the technical scheme takes the far infrared glaze as the ground glaze and carries out high-temperature firing together with the green brick, so as to enhance the far infrared radiation performance of the cockroach-repelling ceramic tile. If regard as the overglaze with the far infrared glaze, can be thrown off partly when the polishing, cause the waste for it is weaker and not lasting to keep away the cockroach ceramic tile and send far infrared light, leads to keeping away the cockroach ceramic tile and keeps away the effect of cockroach relatively poor.

Further, according to the technical scheme, after the fluorescent powder and the glue are mixed to prepare the fluorescent paste body, the super-clean bright A liquid is added to prepare the fluorescent super-clean bright A liquid, and after the far infrared ceramic tile is subjected to soft polishing, the fluorescent super-clean bright A liquid is sprayed on the surface of the far infrared ceramic tile according to a super-clean bright process, so that the cockroach repelling ceramic tile is enabled to generate fluorescence, and the cockroach repelling effect of the cockroach repelling ceramic tile in the technical scheme can be further enhanced. Because the fluorescent powder can only resist the temperature of 700-.

It is worth explaining that far infrared belongs to invisible light, and fluorescence belongs to visible light, this technical scheme uses two kinds of modes of repelling the cockroach of function far infrared light sum fluorescence simultaneously, can play complementary and the effect of reinforcing light intensity, and can not make the people feel the light too strong and influence people's experience sense again, because the cockroach homoenergetic feels far infrared light sum fluorescence, the cockroach is afraid of light simultaneously, under the effect of two kinds of light waves, the cockroach can be more uncomfortable, produce the effect of dodging and do not want to be close and repel the cockroach ceramic tile, thereby reach the effect of repelling the cockroach.

Further, the used far infrared material of this scheme is normal atmospheric temperature far infrared material, can send far infrared light at normal atmospheric temperature, and the fluorescence picture layer that is formed by the super clean bright A liquid of fluorescence then can be kept on for 6-8 hours after external light source closes, make the effective time of keeping away the cockroach that keeps away of this scheme preparation can reach 24 hours, and the duration of the effect of keeping away the cockroach that keeps away the cockroach ceramic tile is one and all the time, can reach and keep away the life-span unanimity of cockroach ceramic tile, because the one-time firing far infrared glaze that becomes of use, the glaze is unanimous with the life-span of ceramic tile, the fluorescence picture layer is then sealed in the capillary hole on ceramic tile surface, can not drop, consequently, the effect of keeping away the cockroach is unchangeable always.

Preferably, the fluorescent powder in one embodiment of the invention is waterproof superfine fluorescent powder of Buddha moment light optical material Co, and the luminance of the fluorescent powder in the technical scheme reaches 9000mcd/m²The light emission duration is 7 to 8 hours.

Further, in the step (1), the mass percentage of the phosphor in the phosphor paste is 30% to 70%.

It is worth explaining that the addition amount of the fluorescent powder in the fluorescent paste body directly influences the fluorescent effect of the cockroach repelling ceramic tile, and if the addition amount of the fluorescent powder is too low, the fluorescent effect of the cockroach repelling ceramic tile is too poor, so that the cockroach repelling rate is low; if too much fluorescent super-clean and bright A liquid or super-clean and bright D liquid is added into the brick, the brick becomes a paste, construction is inconvenient, and even if the fluorescent super-clean and bright A liquid is successfully coated on the surface of the cockroach-repelling ceramic tile, the powder hand feeling of the surface of the brick is easy to generate, and the quality and the attractiveness of the cockroach-repelling ceramic tile are influenced.

Further, the mesh number of the fluorescent powder is 400-1000 meshes.

The size of the fluorescent powder can influence the brightness and granular sensation of the fluorescent powder, in order to keep the fluorescent powder at better brightness and granularity, generally, the thicker the fluorescent powder is, the better the granularity is, the thinner the fluorescent powder is, the brightness can be reduced, but when the fluorescent powder is too thick, the fine and stable fluorescent super-clean A liquid is difficult to prepare, and the thinner the fluorescent powder is, the finer and stable fluorescent super-clean A liquid is easy to prepare, therefore, in the technical scheme, the mesh number of the fluorescent powder is 400-1000 meshes, at the moment, the brightness and granular sensation of the fluorescent powder are both better, and the fine and stable fluorescent super-clean A liquid can be prepared.

Further, in the step (4), the glossiness of the far infrared ceramic tile after soft polishing is 40-50 degrees.

It is worth explaining that according to the technical scheme, the fluorescent super-clean and bright A liquid is sprayed on the surface of the soft-polished far-infrared ceramic tile by adopting a super-clean and bright process, so that the fluorescent super-clean and bright A liquid is filled in capillary holes formed after the soft polishing of the cockroach repelling ceramic tile, and therefore, fluorescent powder can be sealed in the capillary holes on the surface of the cockroach repelling ceramic tile and cannot be separated from the capillary holes, the fluorescent powder can keep the effect of emitting fluorescence all the time, and the cockroach repelling effect and the effective time of the cockroach repelling ceramic tile are effectively improved.

Particularly, when the glossiness that the far infrared ceramic tile carries out after softly throwing is 40 ~ 50 degrees, the brick face is unlikely to too coarse, the hole of brick face capillary hole is great simultaneously, it fills at the hole to be fit for the super clean bright A liquid of fluorescence, thereby make the fluorescence effect preferred of keeping away the cockroach ceramic tile, if the glossiness that the far infrared ceramic tile carries out softly after throwing is higher than 50 degrees, make the hole in the capillary hole of brick face less, the super clean bright A liquid of fluorescence that can fill is less, can influence the fluorescence effect of brick face, thereby the influence is kept away the effect of keeping away of cockroach ceramic tile to the cockroach.

Further, in the step (1), the preparation method of the glue is as follows: mixing sodium carboxymethylcellulose and ethylene glycol according to the ratio of 1:1 to obtain sodium carboxymethylcellulose solution; mixing the sodium carboxymethyl cellulose solution and water glass according to the proportion of 1: 2-1: 5, and obtaining the glue after uniformly mixing.

The glue can play a role in suspension, and the fluorescent powder can be uniformly dispersed in the fluorescent ultra-clean and bright liquid A by preparing the fluorescent powder and the glue into the fluorescent paste body, so that the precipitation is avoided.

Further, the molecular weight of the sodium carboxymethylcellulose is 5000-.

It is worth to be noted that the viscosity of the sodium carboxymethyl cellulose solution is affected by the molecular weight of the sodium carboxymethyl cellulose, and if the molecular weight of the sodium carboxymethyl cellulose is too low, the viscosity of the prepared sodium carboxymethyl cellulose solution is low, the dosage of the sodium carboxymethyl cellulose is increased; if the molecular weight of the sodium carboxymethyl cellulose is too high, the sodium carboxymethyl cellulose is dissolved too slowly, and the difficulty in preparing the sodium carboxymethyl cellulose solution is increased.

Further, in the step (2), in the fluorescent ultra-clean and bright liquid a, the mass percentage of the fluorescent paste body is 5% to 10%.

Specifically, the fluorescent paste with the mass percent of 5-10% is added into the fluorescent super-bright liquid A, so that sufficient fluorescence can be generated, the super-bright waxing technological performance cannot be influenced, the cockroach repelling rate is reduced due to the fact that the fluorescent paste cannot generate sufficient fluorescence when the content of the fluorescent paste is too small, and the super-bright waxing technological performance is not facilitated if the adding amount of the fluorescent paste is too large, so that the adding amount of the fluorescent paste is set to be 5-10%.

Further, in the step (3), ink-jet printing, transparent glaze spraying and firing are sequentially performed on the surface of the far-infrared glaze layer to obtain the far-infrared ceramic tile.

Through carrying out ink-jet printing on far infrared glaze layer surface and can giving and keep away exquisite pattern and color of cockroach ceramic tile, satisfy consumer's demand, drench transparent glaze again after the ink-jet printing, can improve and keep away the surface property who keeps away cockroach ceramic tile, make it have high wear-resisting, corrosion-resistant performance etc..

Further, in the step (4), after the surface of the far infrared ceramic tile is coated with the fluorescent ultra-clear liquid A according to a conventional ultra-clear process, the surface of the fluorescent ultra-clear liquid A is coated with the ultra-clear liquid D to obtain the cockroach-repelling ceramic tile.

The ultra-clean bright liquid D and the fluorescent ultra-clean bright liquid A can synergistically enhance the antifouling effect of the surface of the ceramic tile.

The cockroach-repelling ceramic tile is prepared by the preparation method of the cockroach-repelling ceramic tile and sequentially comprises a ceramic tile blank layer, a far infrared glaze layer, an ink-jet printing layer, a transparent glaze layer, a fluorescent super-clean bright A liquid layer and a super-clean bright D liquid layer from bottom to top.

This technical scheme's the cockroaches ceramic tile of keeping away can send far-infrared light and fluorescence, because the cockroach has negative phototaxis for the cockroach is unwilling to be close to, thereby reaches the purpose of keeping away the cockroach. Meanwhile, the far infrared ray has a certain health care effect on the human body, the nerve on the skin can transmit the stimulation to the brain after the skin of the human body is stimulated by the far infrared radiation, the cranial nerve can immediately generate reaction, the vegetative nerve and the endocrine gland are activated most actively in the generated various reactions, and the activation of the vegetative nerve manages the heart and the vasoconstriction, so that the visceral activity enhances the vasodilatation and the blood flow acceleration, the body function is greatly stimulated, the body resistance is greatly enhanced, and the immunity is improved, thereby achieving the health care effect on the human body. In addition, the fluorescence used in the technical scheme is non-radioactive light, so that harmful radiation to human bodies cannot be caused.

The technical scheme of the invention is further illustrated by combining specific examples and comparative examples.

Table 1 test results of cockroach repelling tiles of examples 1 to 5

As can be seen from the table 1, the cockroach repelling ceramic tile prepared by the technical scheme can effectively repel cockroaches, and the cockroach repelling rate reaches 66% -77%. Furthermore, it is understood from the test data of examples 6 to 8 that, in the preparation process, when other factors are not changed, the higher the mass percentage of the phosphor in the phosphor paste, the better the effect of the cockroach repellent ratio, but in example 8, when the mass percentage of the phosphor is 70%, although the cockroach repellent ratio reaches 75%, the content of the phosphor is too high, which has a certain influence on the brick surface of the cockroach repellent tile, and causes the brick surface to have a slight powder hand feeling. From the test results of examples 9 to 11, it can be seen that, in the preparation process, when other factors are not changed, the glossiness of the far infrared ceramic tile after being subjected to soft polishing is higher, the cockroach repelling rate is lower, and the glossiness of the far infrared ceramic tile after being subjected to soft polishing is maintained between 40 and 50 degrees in order to ensure the cockroach repelling rate of the cockroach repelling ceramic tile.
