Abstract

The invention discloses a waterproof paint for an automobile. The waterproof paint for the automobile is prepared from the following materials by weights: 18-20 parts of potassium metasilicate, 25-30 parts of nano-silica, 33-35 parts of polyvinyl acetate, 16-20 parts of butadiene styrene rubber emulsion, 22-24 parts of isocyanate, 16-20 parts of dicyclohexyl phthalate, 22-26 parts of dibutyl phthalate, 25-30 parts of propylene glycol esters of fatty acid, 14-18 parts of magnesite cement, 23-26 parts of fatty acid polyglycol ester, 12-14 parts of simethicone, 7-11 parts of triethoxysilane, 6-10 parts of rosin modified phenolic resin, 16-18 parts of iron oxide red, 18-20 parts of sodium silicate, 6-9 parts of polyether glycol, and 17-22 parts of tartaric acid. The waterproof paint for the automobile has an excellent waterproof effect, is strong in adhesive force, and has an effect of corrosion resistance at the same time.

Description

technical field [0001] The invention relates to an automobile waterproof paint and a preparation method thereof. Background technique [0002] Automobile coatings refer to the coatings applied on the body and parts of various vehicles such as cars, and generally refer to coatings and auxiliary materials for new cars and coatings for vehicle repairs. Like ordinary paints, automotive paints are generally composed of film-forming substances (resins), additives, pigments, and solvents. At present, my country's automobile sales have continuously exceeded 18 million. The rapid growth of automobile sales has strongly stimulated the continuous development of the automotive coating business and brought huge business opportunities to the automotive coating industry. As the only national and international automotive coating industry event in the industry, China International Automotive Coatings & Coatings Technology Exhibition has always been actively committed to creating value for i...
