NOVELTY - Solar endothermic paint comprises 20-25 pts. wt. deionized water, 10-15 pts. wt. nano composite powder, 6-8 pts. wt. iron oxide, 5-7 pts. wt. adhesive, 4-6 pts. wt. carbon black, 10-15 pts. wt. graphene, 5-8 pts. wt. curing agent, 7-10 pts. wt. epoxy polyurethane resin, 10-13 pts. wt. absolute ethanol, 6-8 pts. wt. dispersant, 12-15 pts. wt. polytetrafluoroethylene, 5-10 pts. wt. alumina, 5-10 pts. wt. silicon carbide, 10-12 pts. wt. obsidian, 10-12 pts. wt. metal platinum and 8-10 pts. wt. carbonate. USE - Solar endothermic paint. ADVANTAGE - The solar endothermic paint has good adhesion, improves the wear resistance and the heat absorbing coating, absorbs solar heat energy so that the photo-thermal conversion efficiency of solar energy is improved, improves the corrosion resistance of the coating material, stability and the weather resistance of the coating. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a solar endothermic paint, which involves: (A) centrifuging graphene, washiung with 8% hydrochloric acid solution and absolute ethanol to neutrality, then placing in a vacuum drying oven, fully drying at a temperature of 60-80 degrees C, and then passing through a grinder grinding into powder to obtain graphene powder, waiting for use; (B) placing nano-composite powder, iron oxide, carbon black, polytetrafluoroethylene and epoxy polyurethane resin into the ball mill, and grinding at a speed of 300-400r / min for 30-40min to obtain first mixture, and taking out the ground products and waiting; (C) placing deionized water, aluminum oxide, silicon carbide, obsidian, metal platinum and carbonate into a high-speed mixer, crushing at 500-600r / min speed for 50-60min in the furnace, then adding the dispersant, binder and curing agent in sequence, standing at a high temperature of 600-800 degrees C, naturally cooling to normal temperature to obtain the second mixture; and (D) placing first mixture obtained and the second mixture into the disperser, and dispersing for 30-50 minutes, taking out the materials, placing into the reaction kettle, adding 10% hydrogen peroxide dropwise, heating to 80-100 degrees C and kepping warm for 1-2 hours to obtaion final product.
