NOVELTY - An exterior silica-alumina inorganic powder coating comprises powder and water in a ratio of 1:0.2-1:0.6. The powder comprises 10 pts. wt. natural resin, 10-40 pts. wt. silicon-aluminum material, 5-10 pts. wt. fiber-based material, 5-20 pts. wt. quartz powder, 5-20 pts. wt. sand, 5-10 pts. wt. sulfonated hyperbranched polypyrrole modified graphene oxide, 5-10 pts. wt. polybenzimidazole modified mesoporous silica, 2-10 pts. wt. KH560 (RTM: ( gamma )- glycidoxypropyltrimethoxysilane), and 0-5 pts. wt. inorganic pigment. USE - Exterior silica-alumina inorganic powder coating (claimed). ADVANTAGE - The exterior silica-alumina inorganic powder coating does not contain volatile organic compound, formaldehyde, ammonia and other volatile harmful substances, and high durability, weather resistance, acid and alkali resistance, color retention property, and thermostatic humidity control and ecological functions.
