Abstract

The invention discloses a method for preparing a ceramic tile antifouling agent. The method for preparing the ceramic tile antifouling agent comprises the following steps of: mixing methyl hydrogen-containing silicone oil, fluoro silicone oil, amino silicone oil and a solvent at the temperature of 10-60 DEG C under a stirring action; adding an adjusting agent to adjust pH value of a system to be between 3 and 8; and continuously stirring for 10-60 minutes to obtain the ceramic tile antifouling agent. After being uniformly coated on the surface of a ceramic tile, the ceramic tile antifouling agent can infiltrate into the surface of the ceramic tile and form a stable chemical bonding action so as to form an organosilicon enhanced protection layer with hydrophobic and oleophobic properties, so that long-acting, high-luminosity and wash-resistant antifouling performance is realized. The ceramic tile antifouling agent prepared by the invention has the advantages of superior performance, wide application range and convenience for production, and is an ideal antifouling nursing agent for modern ceramic tiles.

Description

technical field [0001] The invention belongs to the technical field of tile antifouling, and relates to a preparation method of an antifouling agent for tiles. Background technique [0002] Ceramic tiles are important modern building decoration materials, but the surface of ceramic tiles without anti-pollution treatment is easy to be stained with oil stains, which affects the appearance. In order to solve this problem, various ceramic tile antifouling agents have appeared on the market. Silicone has become an important product for the new generation of tile antifouling technology due to its excellent hydrophobicity, breathability and heat resistance. However, there are many kinds of silicones. How to scientifically select the required silicone varieties and prepare a tile antifouling agent with excellent comprehensive performance and easy use through appropriate processes is a key problem that needs to be solved urgently in this technology.
