NOVELTY - Modified graphene, nano-metal compound, silver-loaded mesoporous silica microspheres and butanediol are added to reactor and stirred at 50-60 degrees C for 0.5-1 hour. Epoxy acrylic resin and catalyst are added to reactor, heated at 200-220 degrees C and reacted for 2-3 hours. Antioxidant 1010 and stabilizer are added to mixture and reacted under vacuum for 3-5 hours to form antistatic antibacterial composite coating. USE - Preparation of antistatic coating used for stainless steel tube. ADVANTAGE - The method enables preparation of coating with high yield and excellent antistatic and antibacterial characteristics and high-temperature processing stability by simple, economical and environmentally-friendly method. DETAILED DESCRIPTION - Modified graphene, nano-metal compound, silver-loaded mesoporous silica microspheres and butanediol are added to reactor and stirred at 50-60 degrees C for 0.5-1 hour. Epoxy acrylic resin and catalyst are added to reactor, heated at 200-220 degrees C and reacted for 2-3 hours. Antioxidant 1010 and stabilizer are added to mixture and reacted under vacuum for 3-5 hours to form antistatic antibacterial composite coating containing 45-50 parts mass epoxy acrylic resin, 31-44 parts mass butanol, 0.5-1 part mass catalyst, 8-12 parts mass modified graphene, 5-8 parts mass silver-loaded mesoporous silica microspheres, 3-8 parts mass nano metal compound, 0.1-0.5 part mass antioxidant 1010, and 0.3-0.8 part mass stabilizer.
