▎ 摘　　要

NOVELTY - Nano wear-resistant graphene crystal coating comprises 10-35 pts. wt. polyurethane resin, 20-40 pts. wt. graphene resin, 15-30 pts. wt. monomer, 0.2-2 pts. wt. additive and 5-10 pts. wt. photoinitiator. USE - The nano wear-resistant graphene crystal coating is useful in electronic device includes mobile phone, laptop, digital camera, photographic camera, audio and other mobile electronic device. ADVANTAGE - The nano wear-resistant graphene crystal coating: exhibits excellent glass texture. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing nano wear-resistant graphene crystal coating, comprising (i) mixing polyurethane resin, graphene resin and organic solvent in a volume ratio of 1:1-3, and stirring at a speed of 300-500 revolutions/minute for 1-3 hours to obtain mixture, and (ii) continuously adding monomer, additive and initiator into the mixture and stirring for 2-5 hours to obtain a nano-wear-resistant graphene crystal coating, and then one-time coating to obtain final product.
