Technical Field

The invention relates to the technical field of ceramic tiles, in particular to a ceramic tile capable of emitting light and presenting a starry sky effect.

Background

The ceramic tile has the characteristics of long service life, low price, easy cleaning and strong decoration, and is widely used for indoor and outdoor decoration. With the continuous improvement of living standard of people, the conventional ceramic tiles gradually start to develop in a diversified manner, and special black golden flower ceramic tiles, flashing ceramic tiles, noctilucent ceramic tiles and the like are derived to meet better decoration effect.

The existing flashing ceramic tile is mainly characterized in that inorganic minerals are added into the ceramic tile, so that the ceramic tile has a punctiform flashing effect under the irradiation of a light source, and the luster is glaring; the fluorescent powder is added into the luminous ceramic tile, and the fluorescent powder in the ceramic tile presents the light of star points after the lamp is turned off, so that a user has better visual perception. At present, most of fluorescent powder or inorganic minerals added into the ceramic tile are added independently, so that the ceramic tile has a noctilucent effect or a flashing effect respectively, and the ceramic tile cannot have the flashing and noctilucent effects. And the noctilucent powder and the inorganic minerals are added into different layers of the ceramic tile simultaneously by part of the ceramic tile, the synergistic effect of the noctilucent powder and the inorganic minerals is weak or has no promotion effect, the noctilucent effect of the ceramic tile is poor after the lamp is turned off, and the decorative effect of starlight flash like a galaxy river cannot be presented.

Disclosure of Invention

The invention mainly aims to provide a ceramic tile capable of emitting light and presenting a starry sky effect, and aims to solve the technical problems that the existing noctilucent ceramic tile or flashing ceramic tile is poor in noctilucent effect and short in light emitting time.

In order to achieve the above object, the present invention provides a ceramic tile capable of emitting light and exhibiting starry sky effect, comprising: a green body layer;

long afterglow inorganic fluorescent material and inorganic mineral with reflectivity not less than 28% are dispersed in the transparent glaze layer;

the long afterglow inorganic fluorescent material and the transparent frit dry particles are dispersed in the dry particle layer.

The body layer is used as a substrate, a transparent glaze layer and an ink-jet pattern layer are arranged on the body layer, the main component of the transparent glaze layer is (transparent) glaze, long-afterglow inorganic fluorescent materials and inorganic minerals which are dispersed and distributed are arranged in the (transparent) glaze, the long-afterglow inorganic fluorescent materials and the inorganic minerals are positioned on the same layer, and when an external light source irradiates, the inorganic minerals can reflect light emitted by the external light source, so that the ceramic tile has the flash luminous decorative effect; when no external light source irradiates, the long-afterglow inorganic fluorescent material emits fluorescence, part of the fluorescence irradiates the inorganic mineral, the fluorescence is reflected by the inorganic mineral, and only when the reflectivity of the inorganic mineral is more than or equal to 28%, the reflection effect on the fluorescence emitted by the long-afterglow inorganic fluorescent material has a good reflection effect; otherwise, the reflectivity is too low, the light reflected by the inorganic mineral is very weak, and only the fluorescence emitted by the long-afterglow inorganic fluorescent material can not present the decorative effect.

The transparent glaze layer is arranged on the ink-jet pattern layer. The ink-jet pattern layer can enable the ceramic tile to have a good decorative effect in the daytime or under the condition of light source irradiation, and preset patterns can be set according to the requirements of users; and the luminous effect of the ceramic tile can be controlled according to the application amount of the pigment of the ink-jet pattern, for example, if more pigment (ink-jet pattern) is applied to two sides of the ceramic tile and the middle is lighter or no pigment (ink-jet pattern) is applied, the two sides can be shielded by the ink-jet pattern, the middle part can not be shielded, and after the lamp is turned off, the starry sky decoration effect can only appear in the part which is not shielded in the middle, like the galaxy. Blank body in the schemeThe layer refers to a conventional tile blank, the transparent frit dry particles are transparent materials which are in a glass state after being fired at a high temperature, and may be conventional transparent dry particles in the production of the tile, such as the transparent dry particles in patent No. CN201410530308.7, and the chemical composition of the transparent frit dry particles in the present scheme may be: according to mass percent, SiO₂32.5％、Al₂O₃48.7％、Fe₂O₃1.2％、Ti₂O0.25％、CaO0.65％、MgO1.15％、K₂O3％、Na₂O2.5%, ZnO2.1%, BaO0.8% and loss on ignition 7.15%, and in other embodiments the raw materials and amounts may be adjusted adaptively. After the long afterglow fluorescent material and the transparent frit dry particles are applied to the dry particle layer positioned on the outermost layer, the long afterglow fluorescent material is dispersed in the glassy transparent frit dry particles through high temperature sintering, and the three-dimensional property of the luminous effect is better.

Wherein the long afterglow inorganic fluorescent material is a fluorescent material which can still emit light when stopping irradiation after being irradiated by natural light sources (such as sunlight and ultraviolet rays) and has longer afterglow time, and comprises sulfide long afterglow inorganic fluorescent materials, such as ZnS: Cu for emitting green light, CaS: Bi for emitting blue and violet light, ZnCdS: Cu for emitting yellow light and the like, and alkaline earth aluminate long afterglow inorganic fluorescent materials, such as SrAl for emitting yellow and green light₂O₄:Eu²⁺，Dy³⁺Sr emitting blue-green light₄Al₁₄O₂₅:Eu²⁺，Dy³⁺Etc.; silicate long persistence inorganic phosphors, e.g. Sr emitting blue light₂MgSi₂O₇:Eu²⁺，Dy³⁺Etc.; other classes of long persistence inorganic fluorescent materials, e.g. purple-emitting Zn₂SiO₄:Sm³⁺And the like. The scheme preferably selects the long-afterglow inorganic fluorescent material with low radioactivity or no radioactivity. The inorganic mineral can be mica material with high reflection.

Preferably, the inorganic mineral has a reflectance of 28 to 40%. The reflectivity of inorganic minerals is further limited, the fluorescent emission effect of the long-afterglow inorganic fluorescent material is better, and the light is not weak.

Preferably, the inorganic mineral is in a flake form. So, flaky inorganic mineral like the mica plate, there is different reflection effect to light at the inside different angles of pottery brick, only partial angle can reflect light, flaky inorganic mineral fuses the angle in transparent glaze layer and respectively has the difference, partial tiling, partial slope, it is partial vertical, also respectively have the difference to the reflection effect of light, when the user walks along pottery brick, partial inorganic mineral will become the state of not reflecting light by the state of reflecting light, the reflection effect is respectively different when walking to different positions, the scintillation effect of star point can be observed to the naked eye promptly, as the continuously flashing star in the night sky.

Preferably, in the transparent glaze layer, the mass ratio of the glaze material, the long afterglow inorganic fluorescent material and the inorganic mineral is 1: 0.15-0.4: 0.02-0.05. In the dry particle layer, the mass ratio of the transparent frit dry particles to the long-afterglow inorganic fluorescent material is 300-310: and 0.01, controlling the application amount of the long-afterglow inorganic fluorescent material and the inorganic mineral according to the application amount of the transparent glaze, limiting the application amount within the range, avoiding the problem that the star light flickering effect cannot be realized due to too small application amount of the long-afterglow inorganic fluorescent material and the inorganic mineral, and avoiding the production cost from being increased due to too much addition amount of the long-afterglow inorganic fluorescent material or the inorganic mineral.

Preferably, the long-afterglow inorganic fluorescent material comprises the following particles with the particle size: the content of 100-120 meshes is 15-23%, the content of 120-150 meshes is 28-33%, the content of 150-180 meshes is 28-32%, and the content of 180-200 meshes is 15-20%;

When the raw materials with different particle sizes are adopted to compound the long-afterglow inorganic fluorescent material, the long-afterglow inorganic fluorescent material with different particle sizes can emit fluorescence with different brightness after the lamp is turned off, and the reflected light of the inorganic mineral is added, so that the ceramic tile can show a starry sky effect of light and shade switching. Similarly, the inorganic mineral particles with different particle sizes have different reflection effects on fluorescence, and can also bring reflected light with different brightness, so that the star effect of the bright and dark connection of the ceramic tile can be further enhanced, and the star light is twinkling and bright.

Preferably, the fluorescent color emitted by the long-afterglow inorganic fluorescent material is at least one of blue-green, yellow-green, sky-blue or purple. In order to ensure the luminous decorative effect of the ceramic tile, two or more long-afterglow inorganic fluorescent materials are preferably matched for use, and under the condition of no light source irradiation, the ceramic tile has the difference of different luminous colors besides the bright and dark luminous effect, so that the decorative effect is stronger. Of course, the scheme can also adopt the long-afterglow inorganic fluorescent material with any one color.

Preferably, the long-afterglow inorganic fluorescent material comprises the following raw materials in percentage by mass: SiO 2₂8-10%、Al₂O₃38-42%、CaO0.1-0.3%、Eu₂O₃0.2-0.5%、Dy₂O₃ 0.4-0.7%、SrO40-45%、B₂O₃2.5-2.8% and MgO2.5-3%.

When the raw materials are used as the long-afterglow inorganic fluorescent material and the inorganic mineral, the fusion effect of the raw materials and the transparent glaze is better, and the glaze quality is improved. Of course, in other embodiments, other fluorescent components and inorganic mineral components may be substituted.

Preferably, the green body layer is white, and the whiteness of the green body layer is greater than 60 degrees. Because the body layer is used as the bottom color which can emit light and present the starry sky effect, when the dark color such as black is used as the bottom color, the luminous presenting effect of the ceramic tile is poorer when no light source irradiates, and the light absorption effect of the black body layer on the long afterglow inorganic fluorescent material is poorer than that of the white body layer, therefore, the white body layer is preferably used as the bottom color, the whiteness of the body layer is further limited to be more than 60 degrees, and the luminous effect is optimal at the moment.

In addition, the invention also provides a preparation process of the ceramic tile capable of emitting light and presenting a starry sky effect.

Referring to the above embodiments, since the ceramic tile capable of emitting light and exhibiting a starry sky effect adopts all the technical solutions of all the above embodiments, at least all the effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

Meanwhile, inorganic minerals with specific shapes of sheets are limited, the inorganic minerals are distributed in different modes in the transparent glaze layer, and the angles of reflected light are different, so that a user can observe the ceramic tile in dynamic conditions such as walking, the ceramic tile has an obvious starlight flickering effect and is similar to a twinkling star in night sky.

Comparative example 3

The comparative example was conducted under the same conditions as in example 3 except that: the inorganic mineral 32 added in this comparative example is located in the inkjet pattern layer 2, which is not located in the same layer as the long-lasting phosphor material 31.

Example 4

The conditions in this example are the same as in example 3, except that: in this embodiment, the long afterglow inorganic fluorescent material 31 comprises the following raw materials by mass percent: SiO 2₂9.05%、Al₂O₃40.88%、CaO0.17%、Eu₂O₃ 0.41%、Dy₂O₃ 0.56%、SrO42.89%、B₂O₃2.55 percent, MgO2.82 percent and loss on ignition 0.67 percent. The inorganic minerals 32 described above include the following raw materials: SiO 2₂39.40%、Al₂O₃13.17%、MgO23.31%、Fe₂O₃0.12%、K₂O10.38%、Ti₂O6.52%, F6.21% and loss on ignition 0.89%.

Comparative example 4

The comparative example was conducted under the same conditions as in example 3 except that: the inorganic minerals 32 of this example are spherical.

The performance tests of examples 1 to 4 and comparative examples 1 to 4 were performed, the luminous effect of each ceramic tile was directly observed by human eyes, and it should be noted that the starry sky effect refers to that a plurality of luminous points (the self-luminous light of the long afterglow fluorescent material and the reflected light of the inorganic mineral) with different brightness are present inside the ceramic tile, and an obvious flashing phenomenon appears along with the walking of human, and a flickering dynamic feeling (the reflection effects of the flaky inorganic mineral at different angles are different) is present during the observation, and the test results are as follows:

table 1 results of performance testing

Detecting items	Starry sky effect	Surface quality
			Example 1	Good effect	Smooth and pinhole-free
Example 2	Good effect	Part of tiny pinholes
			Example 3	Good effect	Part of tiny pinholes
Example 4	Is excellent in	Smooth and pinhole-free
			Comparative example 1	Is poor	/
Comparative example 2	In general	/
			Comparative example 3	Is poor	/
Comparative example 4	In general	/

Note: excellent in starry sky effect > good > general > poor.

The detection process comprises the following steps: selecting starry sky videos and pictures of the same Xinjiang kralay in clear weather and without moonlight as reference, carrying out naked eye observation by 20 observers, comparing the starry sky videos and the pictures with the luminous effect of the ceramic tile capable of emitting light and presenting the starry sky effect in the scheme, and marking that the luminous effect is close to 16 or more positions as excellent; the mark with approximate luminous effect is considered to be good at the 13-15 positions; the marks of 8-12 positions that are considered to have close luminous effects are general; the sign that the luminescence effect is close is considered to be poor by the 3-7 bits.

As can be seen from the test results in Table 1, the ceramic tile capable of emitting light and presenting a starry sky effect has a better light emitting effect than the comparative example, has a special decorative effect like starlight flickering in a night sky, and is better in user experience.
