Description
Technical Field
The invention relates to a ceramic tile antifouling and antiskid treatment process.
Background
With the continuous development of economy and the improvement of domestic living standard, the requirements of people on the visual effect of indoor decoration and the performance of products are stricter. And safety is required first, so that the anti-slip function is highly appreciated. The ultra-clean bright antifouling ceramic tile is popular with more and more consumers, and is prepared by polishing an ultra-clean bright antifouling material, and the ultra-clean bright technology is a high-precision ceramic tile surface treatment method which is generally adopted at present. The skid resistance of the ceramic tile is also an important technical index, so that the ultra-clean and bright anti-fouling ceramic tile with the skid resistance function is a difficult problem in the prior art.
The method for solving the problem of the skid resistance of the ceramic tile is provided; 1. the texture on the surface of the thickened ceramic tile achieves the anti-slip effect, the anti-slip mode can only solve the anti-slip effect during drying, and no anti-slip effect can be achieved when water or oil stains are encountered. This anti-slip method seriously affects the aesthetics of the tile. 2. Concoct an acidic liquid, apply paint on the surface of the ceramic tile with a brush, corrode the ceramic tile ground, let the ceramic tile reach the antiskid effect, this kind of antiskid mode is imperfect, the shortcoming ceramic tile is destroyed, it is on the low side to meet water back coefficient of static friction, form the dirt very easily, the time has been long lost the antiskid effect, great destruction the antifouling and the glossiness of ceramic tile. However, none of the above methods can be used for ultra-clean antifouling tiles.
Chinese patent 201610880415.1 discloses a process for preparing an antifouling brick, which has an antifouling effect by coating a colloidal solution on the surface of the brick and forming a waterproof film after the colloidal solution is dried. The anti-fouling liquid used in the patent is hydrogen-containing silicone oil which has poor alkali resistance and is easily corroded by an alkaline cleaning agent during cleaning; the silica gel solution is also easily abraded away after being soaked in water, resulting in non-durable antifouling capacity.
Chinese patent 201410185232.9 discloses a process for cleaning and brightening a colored polished tile, which can achieve the purpose of preventing stains by coating antifouling liquid and silicone oil on the surface of the tile to seal air holes. The antifouling liquid used in the patent is formed by mixing silica sol and water-soluble color paste, the formula of the water-soluble color paste is adjusted according to the color of the ceramic tile to ensure that the color of the water-soluble color paste is consistent with that of the ceramic tile, the color paste needs to be replaced and a container needs to be cleaned every time the ceramic tile with different colors is produced, and the process is complex; meanwhile, when the ceramic tile with complex color is produced, the preparation and coating of the water-soluble color paste are difficult problems which cannot be solved by the method, and are not beneficial to producing glazed polished tiles with various colors.
In the prior art, the realization of ultra-clean antifouling and anti-skid of the ceramic tile is contradictory, and the ultra-clean antifouling agent is used firstly and then the anti-skid material is polished in the existing industry. Or the anti-skid material is firstly polished and then the ultra-clean antifouling agent is used. However, the super-clean and bright antifouling material is alkaline, and the antiskid material is acidic, so that the antifouling effect is not excessive in practice.
Disclosure of Invention
In order to solve the technical problem, the invention provides a ceramic tile antifouling and antiskid treatment process, which comprises the following steps:
antifouling treatment: uniformly coating an ultra-clean antifouling agent on the surface of a ceramic tile to be treated, and polishing the surface of the ceramic tile until the glossiness of the surface is greater than 85 degrees to obtain the antifouling-treated ceramic tile;
oily antifouling curing treatment: uniformly coating the oily antifouling agent on the surface of the antifouling-treated ceramic tile, and polishing to obtain an oily antifouling cured ceramic tile;
anti-skid treatment: uniformly coating the anti-slip agent on the surface of the oily antifouling cured ceramic tile, and polishing to obtain the anti-slip antifouling ceramic tile;
a cleaning treatment step: washing the surface of the anti-skid and anti-fouling ceramic tile with water, and polishing to obtain the ceramic tile subjected to anti-fouling and anti-skid treatment;
and (3) drying: and drying the cleaned ceramic tile at the temperature of 150-350 ℃ for 0.5-5 minutes.
The temperature of the surface of the ceramic tile is 45-80 ℃ during polishing in the antifouling treatment step.
And the polishing material in the anti-skid treatment step is a wool pad.
The super-clean antifouling agent is an alkaline super-clean antifouling agent containing nano particles.
The oily antifouling agent is a solvent-type oily antifouling agent.
The oily antifouling agent is an organic silicon oily solution containing 1-30wt%
The oily antifouling agent is an alcohol ether oily antifouling agent.
The anti-skid agent is a neutral and weakly acidic anti-skid agent.
The ceramic tile is prepared by adopting the antifouling and antiskid treatment process.
In the prior art, the antifouling agent is a silica sol solution containing nanoparticles (such as silicon dioxide and the like), an ultra-clean and bright effect of the surface is obtained by polishing, the anti-slip agent is an acidic solution with erosion capacity, such as an acidic solution with fluoride ions and ammonium ions, the fluoride ions react with silicate components in the ceramic tile under the action of the ammonium ions in the formula to generate silicon fluoride gas to overflow, and the direct effect of the chemical reaction is that a plurality of nano-scale microporous structures are formed on the surface of the ceramic tile, so that the anti-slip effect is achieved. The ceramic tile after anti-skid treatment has a wider capillary channel after being amplified by a plurality of times through the chemical action with the anti-skid agent, and pits and grooves are formed on the upper layer of the original capillary holes of the ceramic tile, so that the friction coefficient is greatly increased, and the ceramic tile can form a physical sucking disc effect when contacting water or oil stains with the sole, so that the anti-skid effect is greatly increased. Even if the surface of the tile is partially worn over time, the existing structural change portion inside the tile is stable and has a certain depth, so that the anti-slip effect can be maintained for a long time. The invention solves the technical problem of great contradiction between ultra-clean antifouling and anti-skid by arranging a solvent oil antifouling treatment between the antifouling treatment and the anti-skid treatment, and obtains the ceramic tile with excellent antiskid and antifouling effects.
The above-described and other features, aspects, and advantages of the present application will become more apparent with reference to the following detailed description.
