NOVELTY - Preparing high-hardness wear-resistant matte coating involves placing the oxidized graphene in absolute ethanol until it is completely dissolved, ultrasonically processing for 2-3 hours to obtain an oxidizing graphene solution, centrifuging and separating the oxidization graphene solution at a temperature of 65-85degrees Celsius, filtering the filter residue at 50-80degrees Celsius, and drying in a drying box for 2-3 hours, obtaining the graphene powder, then soaking graphene powder and the carbamate monomer at 40-45degrees Celsius for 3-5 hours, after soaking, filtering, washing by deionized water, placing in the drying box at 40-60degrees Celsius drying for 2 -3 hours, preparing the modified graphene resin material. The graphene resin material, fluorocarbon resin, PE powder and silane coupling agent are placed in the reactor, mixed for 40-60 minutes at a speed of 120-160 revolutions/minute (r/min) to obtain mixture A. USE - Method for preparing high-hardness wear-resistant matte coating is used for cosmetics or electronic products. Matte coating material is used for protection of the housing surface (claimed). ADVANTAGE - The graphene high-hardness wear-resistant matte coating prepared by the invention has excellent high hardness and impact resistance, is not easy to scratch, can improve the problems of easy cracking and short service life of cosmetic or electronic product packaging, and is suitable for cosmetic or electronic products. Matte coating material for protection of the outer shell surface of the product. DETAILED DESCRIPTION - Preparing high-hardness wear-resistant matte coating comprises (i) placing the oxidized graphene in absolute ethanol until it is completely dissolved, ultrasonically processing for 2-3 hours to obtain an oxidizing graphene solution, centrifuging and separating the oxidization graphene solution at a temperature of 65-85degrees Celsius, filtering the filter residue at 50-80degrees Celsius, and drying in a drying box for 2-3 hours, obtaining the graphene powder, then soaking graphene powder and the carbamate monomer at 40-45degrees Celsius for 3-5 hours, after soaking, filtering, washing by deionized water, placing in the drying box at 40-60degrees Celsius drying for 2 -3 hours, preparing the modified graphene resin material. The graphene resin material, fluorocarbon resin, PE powder and silane coupling agent are placed in the reactor, mixed for 40-60 minutes at a speed of 120-160 revolutions/minute (r/min) to obtain mixture A, and the monomer and matting agent are added in the mixture A, the temperature is raised to 60-80degrees Celsius, mixed and stirred for 5-10 minutes, then temperature is reduced to 30-40degrees Celsius, the photoinitiator is added, stirred uniformly to obtain mixture B, the curing agent is added to mixture B, stirred for 10-20 minutes, the temperature is continuously raised to 60-80degrees Celsius for 20-40 minutes of ultraviolet irradiation, and then cooled to room temperature to obtain a graphene high-hardness wear-resistant matte coating.
