NOVELTY - Light aging resistant coating comprises 15-17 pts. wt. light-resistant aging paint, 2-5 pts. wt. sodium hydroxide solution, 0.05-0.14 pts. wt. polyvinyl butyral and 0.1-0.2 pts. wt. vinyltrimethoxysilane. USE - Light aging resistant coating is used for bamboo integrated material e.g. wool and bamboo. Uses include but are not limited to a bedding material, a tableware material, an office furniture material and a table cloth material. ADVANTAGE - The light aging resistant coating improves the adhesion problem of the light aging resistant coating, improves the toughness of the light aging resistant coating, improves the water resistance and impact resistance, the coating is not easy to fall off in use, is not easy to be damaged, and prolongs the service life of the substrate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the coating, comprising (i) polishing the surface of the bamboo integrated material for 2-3 times after sequentially the surface of the wood, and drying by cold air to obtain the cleaned bamboo integrated material, (ii) mixing the sodium hydroxide solution with mass fraction of 30%, polyvinyl butyral and vinyl trimethoxy silane, brush coating the cleaned bamboo integrated material surface, drying for 30-40 minutes at 120-140°C, taking out and brushing again, drying, brush coating-drying process is repeated for 2-3 times, forming the primary processing surface of the bamboo integrated material with a base layer of light aging resistant coating, (iii) mixing the modified epoxy resin, 2, 4-dihydroxy-benzophenone, tea polyphenol, trimethylolpropane triacrylate, polyethylene glycol, 2-hydroxy-2-methyl-1-phenyl ketone, polyether siloxane and cellulose ether, adding nano zinc oxide, silane coupling agent KH570 and water into the grinder to fully grind to obtain the light aging resistant coating, and (iv) coating on the base layer using light aging resistant coating, placing the ventilated place to solidify the bamboo integrated material surface.
