Background
As a daily appliance in our life, the ceramic is not stain-resistant and bacteria are easy to grow on the surface due to the self hydrophilicity of the ceramic, the surface of the porcelain insulator is not hydrophobic, dust particles are deposited on the surface of the porcelain insulator to form stains, a conductive film is formed on the surface of the porcelain insulator after the porcelain insulator is contacted with water, and a flashover phenomenon occurs under the action of a strong electric field; the common building porcelain and the daily porcelain have strong hydrophilicity, provide growing environment for bacteria and the like, and bacteria grow on the surfaces of the building porcelain and the daily porcelain to influence the health of people.
The hydrophobic coating can effectively improve the surface hydrophobicity, but has low wear resistance and poor durability, so that the hydrophobic coating gradually loses the hydrophobic effect after being used for a certain time, and the use benefit of the ceramic is greatly influenced. In addition, the traditional hydrophobic material often contains a small amount of harmful substances, and the abrasion and falling of the paint during the use process can generate a certain environmental pollution problem.
