▎ 摘  要

NOVELTY - Wear-resistant graphene antistatic industrial coatings comprises 30-50% of organosilicon modified acrylic resin, silicone-modified acrylic resin is composed of acrylic acid, 3-methacryloxypropyltrimethoxysilane, graphene oxide and sodium oleate are polymerized in a weight ratio of 1:0.2-0.3:0.1-0.3:0.2-0.6. USE - Wear-resistant graphene antistatic industrial coating. ADVANTAGE - Wear-resistant graphene antistatic industrial coating has advantages of good wear resistance, good antistatic property, good dispersibility, high thermal stability, good flame retardance, high strength, good toughness and the like. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) Method for preparing the wear-resistant graphene antistatic industrial coating involves mixing hollow glass microspheres, silicone modified acrylic resin, and emulsifier fully, and stirring evenly; adding dispersant, film-forming aids, other aids, and deionized water, stirring evenly, and discharging. (2) Preparation method of organosilicon modified acrylic resin, which involves: i. fully mixing acrylic acid, 3-methacryloyloxypropyltrimethoxysilane and sodium oleate in a weight ratio of 1:0.2-0.3:0.2-0.6, adding persulfate and water, heating and reacting to obtain a copolymer; ii. adding ethylenediamine and graphene oxide to the copolymer prepared in step 1, adjusting the pH value, and reacting at room temperature, weight ratio of the acrylic acid to the graphene oxide is 1:0.1-0.3.
