Problems solved by technology

[0006] The above four kinds of coatings or coating resins with waterproof and oil-repellent functions can all provide a coating surface with hydrophobic and oleophobic functions, and the realization of the hydrophobic and oleophobic functions of the coating surface is different, but the use of fluorine-containing polymers can reduce the The surface energy of the paint will also reduce the adhesion between the paint and the substrate, especially for cabinet boards that are prone to oil stains. Insufficient effort, it is easy to have poor abrasion resistance, easy peeling, waterproof and oil-proof effect and poor durability of the coating; in addition, from the perspective of fluorine-containing polymer coatings currently on the market, among the fluorine-containing acrylate coatings It mainly relies on the C-F bond on the side chain to protect the main chain. The distribution of fluorine-containing groups is relatively scattered. In the case of relatively complex polymer chains, it is difficult to reach a large number of fluorine-containing groups after the coating is formed. Paint surface, resulting in poor hydrophobic and oleophobic function of the paint
