Technical Field

The application relates to the field of thermoplastic elastomer additives, in particular to a deodorant, application thereof and a preparation method thereof.

Background

Thermoplastic elastomers (TPEs), also known as elastomers or synthetic rubbers, are widely used in elastic products such as artificial skin, foamed toys, etc. because of their advantages of high resilience, high transparency, soft touch, environmental protection, non-toxicity, etc.

The processing of thermoplastic elastomeric materials typically includes the steps of injection molding or casting. In order to adjust the hardness of the thermoplastic elastomer material and to improve the processability of the thermoplastic elastomer material, white mineral oil is often added to the thermoplastic elastomer material. However, the flash point of the white mineral oil is low and is only about 150 ℃, while the temperature of the thermoplastic elastomer material during injection molding or pouring is often as high as about 180 ℃, even as high as 230 ℃, so that the thermoplastic elastomer material is easily ignited by a flame during processing, and therefore, the thermoplastic elastomer material usually has an obvious and unpleasant white mineral oil smell after processing, and the more the white mineral oil is added, the larger the generated smell is, which greatly affects the use experience of the product.

At present, plastic deodorant exists on the market and is used as thermoplastic elastomer additive for removing peculiar smell in thermoplastic elastomer materials, but the common plastic deodorant has not ideal effect of removing white mineral oil smell, so that the development of deodorant capable of efficiently removing the white mineral oil smell is needed.

Disclosure of Invention

In order to be able to remove the white mineral oil odor in thermoplastic elastomer materials with high efficiency, the application provides a deodorant, the application thereof and a preparation method thereof.

In a first aspect, the present application provides a deodorant, which adopts the following technical scheme:

the deodorant comprises the following raw materials in parts by weight:

40-50 parts of silicon dioxide microspheres

55-70 parts of silicate clay

180 portions of acidic aqueous solution 160-

30-35 parts of monomer containing functional group X

5-9 parts of a nano hole making agent;

the main component of the deodorant is silica-silicate gel.

By adopting the technical scheme, the deodorant is prepared into silica-silicate porous gel with micropores on the surface through silica microspheres, silicate clay, an acidic aqueous solution, a monomer containing a functional group X and a nano pore-making agent, and the aim of efficiently removing the odor of white mineral oil is fulfilled by adsorbing gas molecules through the micropores on the surface of the silica-silicate gel.

The silicate clay and the monomer containing the functional group X are subjected to chemical reaction, the surface of the silicate clay is modified by the functional group, and the modified silicate clay and the silica microspheres react to form silica-silicate gel. The silica-silicate gel prepared by the method has a crystalline structure and an amorphous structure at the same time, forms a gradient nano-micron microporous structure, can contain different odor molecules, and can prevent the gas molecules from escaping, so that the capability of adsorbing the gas molecules is stronger, and the effect of removing the odor of the white mineral oil is better.

Preferably, the silica-silicate gel has micropores on the surface thereof, and the pore diameter of the micropores is 1 to 10 μm.

By adopting the technical scheme, the pore diameter of the micropores is one of important influence factors influencing the gas molecule adsorption efficiency of the silica-silicate gel, the pore diameter of the micropores is too small, the passage of gas molecules through the micropores is reduced, the restriction effect exists, and the gas molecule adsorption efficiency of the silica-silicate gel is reduced. To a certain extent, the larger the pore size of the micropores, the higher the adsorption efficiency of the silica-silicate gel, but the too large micropores, the more quickly the silica-silicate gel adsorbs to saturate, which is not conducive to the continuous deodorization of the deodorizing agent. The pore diameter of the micropores of the silica-silicate gel is 1-10 μm, the composition of a gradient nano-micron microporous structure can be realized, and the balance between the adsorption efficiency and the adsorption time is obtained, which is right suitable.

Preferably, the surface of the silica-silicate gel is coated with a biodegradable material.

By adopting the technical scheme, after the biodegradable material is coated on the surface of the silicon dioxide-silicate gel, a layer of film can be formed on the surface of the silicon dioxide-silicate gel. In the using process of the product, the biodegradable material can be degraded under the action of microorganisms such as bacteria, fungi, actinomycetes and the like in life. The addition of the biodegradable material enables micropores on the surface of the silicon dioxide-silicate gel to be covered in the early stage and then exposed in the later stage, relieves the rapid adsorption of the silicon dioxide-silicate gel to gas molecules, and has the effect of prolonging the adsorption time of the deodorant.

Preferably, the biodegradable material comprises one or a combination of more of chitin, polylactic acid and polycaprolactone.

By adopting the technical scheme, the chitin, the polylactic acid and the polycaprolactone are common biodegradable materials, are convenient to obtain, have low cost and are very suitable for coating the silicon dioxide-silicate gel.

In a second aspect, the present application provides an application of a deodorant, which adopts the following technical scheme:

By adopting the technical scheme, the deodorant is applied to products such as medical oxygen inhalation masks, medical oxygen therapy tubes, medical infusion tubes, glue, printing ink, foaming toys and the like, and is wide in application and high in practicability.

Preferably, the weight proportion of the deodorant in the thermoplastic elastomer material is 0.4% -2%.

By adopting the technical scheme, tests show that the deodorant can achieve the effect of efficiently deodorizing when the weight proportion of the deodorant in the preparation of the product is 0.4-2%, and the addition of too much deodorant can increase the production cost of the product, reduce the weight proportion of the thermoplastic elastomer material and influence the comprehensive performance of the product.

In a third aspect, the application provides a preparation method of a deodorant, which adopts the following technical scheme:

a method for preparing a deodorant, comprising the steps of:

s1: dissolving silicate clay into an acidic aqueous solution, adding a monomer containing a functional group X, heating and stirring to obtain modified silicate clay;

s2: adding the silicon dioxide microspheres and the nano pore-making agent into the modified silicate clay, stirring and uniformly mixing, heating, and drying to obtain silicon dioxide-silicate gel; and (4) nano-crushing the silica-silicate gel to obtain the deodorant.

By adopting the technical scheme, in S1, the silicate clay is modified by adding the monomer containing the functional group X into the silicate clay. In S2, silica-silicate gel is prepared by the interaction between the modified silicate clay and the silica microspheres, and the nano-pore forming agent forms a plurality of micropores on the surface of the prepared silica-silicate gel to contain gas molecules.

Preferably, the method further comprises the step of S3: adding a part of the silicon dioxide-silicate gel into a biodegradable material, heating and stirring the mixture until the mixture is dried, and then carrying out nano crushing to obtain a product A; and (3) directly carrying out nano crushing on the rest silicon dioxide-silicate gel to obtain a product B, and uniformly mixing the product A and the product B to obtain the deodorant.

By adopting the technical scheme, the biodegradable material is added into part of the silica-silicate gel, so that the surface of the part of the silica-silicate gel can generate a film, the part of the silica-silicate gel can play a role after the biodegradable material is expected to be degraded, the adsorption effect of the silica-silicate gel on gas molecules is properly inhibited, and the effect of prolonging the acting time of the deodorant is achieved.

Preferably, the silica-silicate gel is sterilized in S3.

By adopting the technical scheme, the silica-silicate gel is sterilized before the biodegradable material is coated, so that the influence of microorganisms on the biodegradable material on the silica-silicate gel can be reduced, the biodegradable material is effectively prevented from being degraded in advance, and the adsorption time of the deodorant is prolonged.

In summary, the present application has the following beneficial effects:

1. according to the deodorant, silica-silicate porous gel with micropores on the surface is prepared from silica microspheres, silicate clay, an acidic aqueous solution, a monomer containing a functional group X and a nano pore-making agent, and gas molecules are adsorbed by the micropores on the surface of the silica-silicate gel, so that the aim of efficiently removing the odor of white mineral oil is fulfilled.

Detailed Description

The present application will be described in further detail with reference to examples.

The thermoplastic elastomer is rubber with the advantages of high rebound resilience, high transparency, soft touch, environmental protection, no toxicity and the like, and has wide application. In the production of products, white mineral oil is usually added inevitably to adjust the hardness and softness of thermoplastic elastomer materials and to improve the processing of thermoplastic elastomer materials. However, the addition of the white mineral oil brings obvious and unpleasant white mineral oil odor to the product, thereby influencing the use experience of the product, and the removal effect of the plastic deodorant on the market on the white mineral oil odor is not ideal.

In order to solve this problem, the present applicant has conducted extensive studies on the formulation of a deodorant, and as a result, found that commercially available plastic deodorants have a weak adsorption effect on gas molecules, thereby hindering the deodorizing effect of the deodorant.

Based on this finding, the applicant has conducted a great deal of research into the formulation of deodorants in an attempt to find a process capable of efficiently removing the odor of white mineral oil from thermoplastic elastomeric materials. As a result, the present applicant has found that a silica-silicate gel having micropores prepared using a modified silicate clay and silica microspheres can efficiently adsorb gas molecules, thereby successfully solving the technical problems to be solved by the present application. In addition, the surface of the silica-silicate gel is coated with the biodegradable material, so that the adsorption time of the deodorant can be prolonged. The present application has been made based on the above findings.

The raw materials are purchased from the market, wherein the silicon dioxide microspheres are selected from Jiangsu Xiancheng nano material science and technology limited company, and the silicate clay is selected from Dongguan Quanwei new material science and technology limited company.

Comparative example

Comparative example 1

Comparative examples 5 to 8

Comparative examples 5 to 8 disclose a medical oxygen mask, which is different from the medical oxygen mask of example 8 in that the medical oxygen mask of comparative examples 5 to 8 respectively applied the deodorants of comparative examples 1 to 4.

Odor detection test

According to the german VDA 270 odor test reference standard, the medical oxygen inhalation mask of examples 8-14 and comparative examples 5-8 were subjected to odor test, and the odor grade of each medical oxygen inhalation mask was counted, and the specific test results are shown in table 1.

The following are reference standards:

TABLE 1 odor test results of medical oxygen mask of examples 8 to 14 and comparative examples 5 to 8

As can be seen from table 1, the medical oxygen mask of examples 8 to 14 has an odor grade of 2 or less, while the medical oxygen mask of comparative example 5 has an odor grade of 4, which indicates that the medical oxygen mask emits less odor, hardly affects the user, and produces a significant odor improvement effect compared to the medical oxygen mask manufactured using commercially available odor eliminators.

The odor rating of comparative example 6 was 3, indicating that the odor removing effect of the odor removing agent of the present application could not be achieved by using the ordinary silicate clay to prepare the odor removing agent, thereby proving that the modification of the functional groups on the surface of the silicate clay contributes to the enhancement of the adsorption force of the silica-silicate gel to gas molecules, so that the silica-silicate gel firmly adsorbs the gas molecules, thereby removing the odor more efficiently.

In the thermoplastic elastomer material, when the content of the deodorizing agent is 0.2%, the deodorizing efficiency is lowered and the deodorizing effect is deteriorated. When the content of the deodorant is 4%, the efficiency of the deodorant has exceeded the upper limit, and the deodorizing effect is not significantly different from that when the content of the deodorant is 2%.

Odor removal persistence test

The medical oxygen mask of example 8, examples 11 to 14 and comparative example 5 was left in the same environment for 6 months, the odor of the medical oxygen mask of example 8, examples 11 to 14 and comparative example 5 after 1 day and 6 months was measured according to the german VDA 270 odor test reference standard and the reference standard of the above odor detection test, and the odor grade of each medical oxygen mask at each time was counted, and the specific test results are shown in table 2.

Table 2 results of odor removal durability test of medical oxygen inhalation mask of example 8, examples 11 to 14, and comparative example 5

As can be seen from Table 2, the medical oxygen mask prepared by using the deodorant of the present application still has a good deodorizing effect after 6 months, and particularly, the medical oxygen mask of examples 11-14 has a smell grade of 1.5 all the time, which indicates that the deodorizing persistence of the deodorant of the present application is very good. As the biodegradable material is degraded, the micropores on the surface of the silica-silicate gel are more exposed, and the silica-silicate gel can continuously adsorb gas molecules, so that the deodorization time is more favorably prolonged, and the deodorization method has obvious improvement compared with the commercial deodorization agent.

To further investigate the duration of odor elimination of the odor eliminating agent, the medical oxygen mask of example 8 and examples 11 to 14 was continuously tested, and the odor grade of the medical oxygen mask was further tested after 12 months. As a result, it was found that the medical oxygen mask of examples 11 to 13 had a change in odor grade of 2 after 12 months, while the medical oxygen mask of example 14 still had an odor grade of 1.5 after 12 months, and it was found that pre-sterilization of the silica-silicate gel slowed the degradation of the biodegradable material, resulting in a longer adsorption time for odor elimination.

The more the micropores of the surface of the silica-silicate gel are covered, the better the deodorizing ability of the deodorizing agent is continued, but the deodorizing ability of the deodorizing agent is lowered in the previous stage, so that the present application also studies the weight ratio between two silica-silicate gels on the deodorizing ability and the deodorizing ability of the deodorizing agent. According to the odor removal persistence test, the weight ratio of two parts of silica-silicate gel is respectively set to be 2:1, 1:1 and 1:2, and the test result shows that when the weight ratio of the two parts of silica-silicate gel is 1:1, the initial odor level of the odor removal agent is low, and the odor removal persistence is ideal, so that a relative balance state is achieved between the odor removal efficiency and the odor removal persistence, and the efficient odor removal and the persistent odor removal are realized.

In addition, the odor detection test and the odor removal continuity detection test are simultaneously carried out on the medical oxygen delivery pipe, the medical infusion pipe, the glue, the printing ink and the foaming toy which are made of the thermoplastic elastomer material, the test result is not obviously different from the test result of the medical oxygen inhalation mask, and the application range of the odor removal agent is very wide and the practicability is very high.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
