Abstract

The invention relates to high-performance fluorosilicone modified finish-coat paint. Fluorosilicone modified acrylate is taken as a main raw material, the film-forming property is excellent, the adhesive force is high and the hydrophobic property is excellent; the epoxy silane modified silica sol is adopted for improving the surface property of the film coating, the dispersity is excellent and the surface performance of the film is uniform; the graphene oxide is added, so that the adhesive force, flexibility, shock resistance, water tolerance, salt resistance and hardness of the finish-coat paint can be greatly promoted; an anti-microbial mildew preventive is selected from a Chinese herbal medicine extracting solution, is safe, environment-friendly and nontoxic and has excellent sterilizing property; a stain-resistant additive is beneficial to the promotion of stain resistance of the finish-coat paint; the finish-coat paint provided by the invention has the advantages of adhesive force reaching up to level 2, static contact angle of 110-120 degrees between a film and water, high flexibility, excellent shock resistance, high hydrophobicity, water resistance, salt resistance, stain resistance, no volatile organic compound, safety, environmental protection, anti-microbial and mold-proof effects and long service life.

Description

technical field [0001] The invention relates to the technical field of a fluorine-silicon modified finish paint, in particular to a high-performance fluorine-silicon modified finish paint. Background technique [0002] Building exterior wall coatings can beautify the environment and the living room, but due to the poor weather resistance and stain resistance additives of traditional coatings, the coating will change color and stain after a short period of time. As urban environmental pollution is intensifying, dust pollution and gas pollution are particularly serious. [0003] Real stone paint, textured paint and water-based colorful paint are now popular and widely used, but each has its own defects. Real stone paint has poor stain resistance, textured paint and water-based colorful paint have poor water and weather resistance. In order to solve this problem, construction A finish coat is required at the end. [0004] Fluorosilicone finishes are mainly used to protect the...
