Description

Technical Field

[0001] The invention relates to the technical field of anti-skid products, and in particular to a preparation method of an anti-fouling and anti-skid agent and application thereof. Background Art

[0002] More and more buildings use bright hard materials such as marble, tiles, and mosaics. These materials are indispensable for hospitals, schools, exhibition halls, hotels, supermarkets, shopping centers, restaurants, gymnasiums, swimming pools, and kitchens. However, the problem that follows is that slipping accidents continue to occur due to the smoothness of the ground, and even cause human disability. Among them, young children, the elderly, pregnant women, and people with limited mobility are the most serious, so ground anti-slip has become a major issue of public safety.

[0003] In order to make the floor anti-slip, one method is to make the floor into a macroscopic uneven structure, and use this structure and the mechanical bite effect of the sole under pressure to increase the friction coefficient. However, this method destroys the decorative effect of the floor, and has high requirements for the processing method, which increases the difficulty of tile processing. Another method is to apply an anti-slip agent on the floor, and use the anti-slip agent attached to the floor to increase the friction coefficient. Therefore, anti-slip agents have been widely studied and reported, such as the patent technical document CN109536135B discloses an anti-fouling and anti-slip agent for marble floor tiles and its preparation method. The invention includes the following components: 0.1-3 parts of an acid with a pKa of 2-4; 1-5 parts of a fluoride salt; 0.05-4 parts of a non-ionic surfactant; 0.1-2 parts of a brightener; 0.1-3 parts of an additive; and 80-100 parts of water. The acid with a pKa of 2-4 is composed of nitric acid, hydrofluoric acid, and citric acid.

[0004] However, these existing anti-slip agents still have the following disadvantages: the anti-slip agent layer will gradually wear out and lose its anti-slip effect as the use time increases; the main raw materials of anti-slip agent products are oxalic acid and hydrofluoric acid, oxalic acid is highly toxic and will cause serious pollution to groundwater; the use of anti-slip agents is relatively single, and some anti-slip agents are only suitable for indoor floors; the stain resistance is relatively poor, and it is easy to leave stains, it is not easy to clean, and the stability of resistance to cold and hot cycles is poor.

[0005] Therefore, according to the above-mentioned related technologies, it is urgent to develop a preparation method and application of an anti-fouling and anti-slip agent. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a preparation method of an anti-fouling and anti-skid agent and its application, so as to solve the problem that the anti-fouling ability of the anti-skid agent prepared in the prior art is poor.

[0085] Performance Test:

[0086] Friction coefficient test:

[0087] Referring to the test standard of JC / T1050-2007 "Classification and Test Methods of Anti-slip Performance of Floor Stone", the friction coefficient of Marco Polo tiles was tested in dry state, wet state and 12 months after dry treatment. The size of the floor tile is 150mm×150mm×5mm; the dry state is to dry the marble floor tile treated with anti-fouling and anti-slip agent at 30℃ for 60 minutes; the wet state is that the water content on the surface of the marble floor tile is ≥0.1mm. The calculation method of the friction coefficient retention rate after 12 months: the initial tile friction coefficient is recorded as A1, and the tile friction coefficient after 12 months is recorded as A2; the test results are shown in Table 1; the friction coefficient retention rate calculation formula is as follows;

[0088]

[0089] Gloss test:

[0090] The gloss meter model WGG60-E4 produced by Koshijia Optoelectronic Instrument Co., Ltd. was used to test the gloss of the tiles treated with anti-fouling and anti-slip agents in the dry state and the gloss retention rate after 12 months; the initial gloss was recorded as B1, and the gloss after 12 months was recorded as B2; the test results are shown in Table 1; the gloss retention rate (%) is calculated as follows:

[0092] Stability test:

[0093] According to the test standard of GB / T4893.7-2013 "Test for physical and chemical properties of furniture surface paint film Part 7: Determination of temperature difference between hot and cold temperatures", the stability of the hot and cold cycles of the tiles treated with the anti-fouling and anti-slip agents prepared in Examples 1 to 4 and Comparative Examples 1 to 6 was tested to observe whether there was cracking after 30 cycles.

The measurement results are shown in Table 1;

[0096] Table 1

[0097]

[0098] Data Analysis:

[0099] As can be seen from Table 1, the anti-fouling and anti-skid agent prepared by the present invention has better anti-skid ability, anti-skid stability, gloss improvement ability and stability, freeze-thaw stability and anti-fouling ability;

[0100] This may be due to the specific proportion of nano titanium dioxide, nano silicon dioxide and triethanolamine added to the anti-fouling and anti-skid agent of the present invention, which effectively improves the anti-fouling, self-cleaning, antistatic, antibacterial, anti-ultraviolet and other properties of the anti-fouling and anti-skid agent; the hydrogen bonds of the polyvinyl alcohol in the homemade anti-skid active agent of the present invention and the hydroxyl groups on the methyl cellulose molecular chain can generate a multi-dimensional membrane with a three-dimensional structure, reducing the active hydroxyl group to improve the anti-skid ability, while the water-soluble starch and fatty alcohol polyoxyethylene can improve the freeze-thaw stability, anti-fouling ability and self-cleaning ability; therefore, the addition of the anti-skid active agent can improve the anti-skid ability and service life of the anti-skid agent, and can further improve the anti-fouling ability and self-cleaning ability of the anti-fouling and anti-skid agent. The invention modifies the high hydrogen silicone oil, and effectively improves the self-emulsification ability of the silicone oil, the centrifugal stability of the emulsion, the thermal stability, the low temperature stability, the freeze-thaw stability, and the acid, alkali and electrolyte resistance of the silicone oil; then, the silicone oil is compounded with glycerol with good water absorption and sodium lactate which can lock water by forming hydrogen bonds with water molecules in a specific ratio, so that a stable film integrating water absorption and water retention can be formed on the surface of the ceramic tile after being treated with the anti-fouling and anti-slip agent; therefore, the addition of a moisturizer prepared by glycerol, modified silicone oil and sodium lactate in a specific ratio can not only improve the water retention capacity of the anti-fouling and anti-slip agent, but also cooperate with an antioxidant to improve its antioxidant capacity.

[0101] Compared with Example 1, Comparative Example 1 only replaces "1g glycerol, 3g modified silicone oil, 1g sodium lactate" added in the preparation process of the moisturizer with "5g glycerol"; Compared with Example 1, Comparative Example 2 only replaces "1g glycerol, 3g modified silicone oil, 1g sodium lactate" added in the preparation process of the moisturizer with "2g glycerol, 3g modified silicone oil". It can be seen from Table 1 that compared with Example 1, the anti-skid ability, anti-skid stability, gloss improvement ability and stability, freeze-thaw stability and anti-fouling ability of Comparative Examples 1 and 2 are all reduced. This may be due to the modification of the high hydrogen silicone oil in the present invention. It effectively improves the self-emulsification ability of silicone oil, centrifugal stability of emulsion, thermal stability, low temperature stability, freeze-thaw stability, and acid, alkali and electrolyte resistance; then it is compounded with glycerol with good water absorption and sodium lactate that can lock water by forming hydrogen bonds with water molecules in a specific proportion, so that a stable film that combines water absorption and water retention can be formed on the surface of the tile after being treated with the anti-fouling and anti-slip agent; therefore, the addition of a moisturizer prepared by glycerol, modified silicone oil and sodium lactate in a specific proportion can not only improve the water retention capacity of the anti-fouling and anti-slip agent, but also cooperate with the antioxidant to improve its antioxidant capacity;

[0102] Comparative Example 3 Compared with Example 1, only the "1g anti-skid active agent" added in the preparation process of the anti-fouling and anti-skid agent is replaced with "1g non-ionic surfactant (fatty alcohol polyoxyethylene ether)". It can be seen from Table 1 that compared with Example 1, its anti-skid ability, anti-skid stability, gloss improvement ability and stability, and freeze-thaw stability are slightly reduced. This may be because compared with the non-ionic surfactant, the hydrogen bonds of the polyvinyl alcohol in the homemade anti-skid active agent of the present invention and the hydroxyl groups on the methyl cellulose molecular chain can generate a three-dimensional multi-dimensional membrane, reducing the active hydroxyl group, thereby improving the anti-skid ability, while the water-soluble starch and fatty alcohol polyoxyethylene can improve the freeze-thaw stability, anti-fouling ability and self-cleaning ability of the anti-skid active agent;

[0103] Compared with Example 1, Comparative Example 4 only replaces "1g nano titanium dioxide, 1g nano silicon dioxide, 3g triethanolamine" added in the preparation process of the antifouling composition with "5g nano titanium dioxide"; Compared with Example 1, Comparative Example 5 only replaces "1g nano titanium dioxide, 1g nano silicon dioxide, 3g triethanolamine" added in the preparation process of the antifouling composition with "5g triethanolamine"; It can be seen from Table 1 that compared with Example 1, the antifouling ability of Comparative Examples 4 and 5 is significantly reduced, which may be due to the specific proportion of nano titanium dioxide, nano silicon dioxide, and triethanolamine added to the antifouling and anti-skid agent of the present invention, which can effectively improve the antifouling, self-cleaning, antistatic, antibacterial, anti-ultraviolet and other properties of the antifouling and anti-skid agent;

[0104] In Comparative Example 6, during the preparation of the anti-fouling and anti-skid agent, the components are directly mixed and then stirred evenly. It can be seen from Table 1 that compared with the process of Example 1, "first, 22g of ethylene glycol amine, 1.4g of anti-skid active agent, and 5.6g of anti-fouling composition are added in sequence to 53g of deionized water, and the pre-dispersion liquid is obtained after stirring evenly; then, 6g of moisturizer is added to 82g of the pre-dispersion liquid, and the mixture is stirred at 850rpm for 7min, and then 2g of citric acid and 2g of sodium citrate are added in sequence, and the anti-fouling and anti-skid agent is obtained after stirring evenly.", the anti-skid ability, anti-skid stability, gloss improvement ability and stability, freeze-thaw stability and anti-fouling ability are all reduced. This may be because the present invention can generate the most ideal anti-fouling and anti-skid agent by mixing the reaction in a specific order, while directly mixing and stirring all the components will generate other by-products that affect the performance of the anti-fouling and anti-skid agent.
