Abstract

The invention relates to a weather-proof protection paint resistant to wind sand erosion. The weather-proof protection paint resistant to wind sand erosion is prepared from, by weight, 5-30% of hydroxyl acrylic resin, 5-30% of a polyurethane polymer, 0.1-2% of a catalyst, 0.1-2% of a leveling agent, 0.1-2% of an ultraviolet light absorber, 0.1-2% of a light stabilizer, 0.1-2% of an antioxidant and 40-70% of a solvent, wherein the weight percents of all the components is 100%. The weather-proof protection paint resistant to wind sand erosion has light degradation resistance, heat resistance, ultraviolet aging resistance and hydrolysis resistance, has excellent wind sand erosion resistance and transparency and can be used in outdoor environments with strong wind sand and environments with high transparency requirements; a coating formed by the weather-proof protection paint resistant to wind sand erosion is high in strength and good in elasticity and can well resist outside destructive power on the coating.

Description

technical field [0001] The invention relates to a coating, in particular to a weather-resistant protective coating against wind and sand erosion. Background technique [0002] Polyurethane coating is a kind of coating with a large amount and a wide range in modern coatings, endowing it with the functions of decoration and protection. There are more and more studies on polyurethane coatings. The prior art proposes a polyurethane waterproof coating, which consists of the following raw materials in parts by weight: 40-50 parts of water-based polyurethane, 20-30 parts of silicon acrylate emulsion, and 10-30 parts of polyvinyl alcohol. 20 parts, 10-20 parts of diphenylmethane diisocyanate, 2-10 parts of talcum powder, 2-10 parts of anhydrous calcium chloride, 1-5 parts of sodium hexametaphosphate, 1-5 parts of potassium silicate , 0.2-0.8 parts of triethylenediamine, 0.2-0.8 parts of glyoxal, 0.4-2 parts of dibutyl phthalate, 0.4-2 parts of silica fume powder and 10-20 parts of ...
