NOVELTY - A coating solution contains graphene, polyurethane resin and water in a mass ratio of (0.18-0.23):100:(50-80). USE - Coating solution is useful for preparation of leather products (claimed). ADVANTAGE - The coating solution has excellent wear resistance, scratch resistance, antistatic properties, absorption effect, antibacterial properties, mildew resistance, UV resistance, aging resistance, electromagnetic shielding performance and durability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of coating solution, which involves weighing graphene and then soaking in acid solution including sulfuric acid and phosphoric acid, adding remaining raw materials and then uniformly mixing, heating the mixture, and stirring; and (2) use of coating solution for preparation of leather products, where leather includes knitted fabric, woven fabric, nonwoven fabric and microfiber nonwoven fabric.
