NOVELTY - Coating composition comprises 0.001-10 pts. wt. graphene filler, 10-30 pts. wt. resin, 10-30 pts. wt. titanium dioxide, 10-30 pts. wt. solvent, 1-10 pts. wt. curing agent, and 0-25 pts. wt. auxiliary agent. USE - The coating composition is useful for solar cell back board (claimed). ADVANTAGE - The coating composition has good mechanical performance and good thermal conductivity (heat fast, high temperature, high safety, improve battery life); high resistance to ultraviolet (resistance to aging, enhanced weather resistance); and has wide application in all kinds of environment climate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the coating composition comprising mixing the graphene filler, resin, titanium dioxide and solvent, performing ultrasonic processing, adding curing agent and auxiliary agent, uniformly mixing to obtain the product; and (2) producing a solar cell back board coated with the coating composition comprising mixing graphene filler and PET chips, kneading, extruding, drum shaping and biaxial stretching to obtain the solar battery back board, treating surface of the solar cell back board with a low temperature plasma, coating the surface of the solar cell back board with the coating composition, drying and curing.
