Summary: | The invention provides an ultraviolet-resistant composition which comprises the following components: nano silica sol, nano alumina sol, a diphenyl ketone type light stabilizer, 2-(2'-hydroxyl -5'-methyl phenyl) benzotriazole, a surfactant, a pH value adjusting agent and water. The composition provided by the invention can be dissolved into water, is high in stability and is not decomposed or deteriorated at 90 DEG C. When being applied to the surface of an aluminum product, the composition provided by the invention is capable of remarkably improving the ultraviolet resistance of the aluminumproduct, meanwhile, the acid-base corrosion resistance of the aluminum product is improved, and the quality of the aluminum product is comprehensively improved. In addition, the composition is appliedto the surface of the aluminum product, the aluminum product can be industrially treated, the surface of the treated aluminum product is free of greasy feeling, the production efficiency is high, theproduction cost is lowered |
