NOVELTY - Sulfonamide-silver compound doped graphene zinc powder heavy-duty anti-corrosion coating, comprises 2-10 pts. wt. graphene, 10-18 pts. wt. epoxy resin, 8-15 pts. wt. alkyd resin, 1-5 pts. wt. sulfonamide-silver compound, 30-40 pts. wt. zinc powder, 10-15 pts. wt. vegetable oil fatty acid, 5-15 pts. wt. pigments and fillers, 5-8 pts. wt. pentaerythritol, 1-3 pts. wt. fumed silica, 15-25 pts. wt. reactive diluent and 5-20 pts. wt. curing agent. USE - Used as sulfonamide-silver compound doped graphene zinc powder heavy-duty anti-corrosion coating. DETAILED DESCRIPTION - Preparing sulfonamide-silver compound doped graphene zinc powder heavy-duty anti-corrosion coating comprising (1) placing graphene and sulfonamide-silver compound in the mixing device and stirring, where the stirring speed is 200-350 revolutions per minute, and the stirring time is 25-30 minutes, mixing evenly, then grinding by sand mill, where the speed is 235-350 revolutions per minute, and the grinding time is 9-12 minutes, then placing in a microwave reactor after grinding, set the power to 135-255 w, and reacting at 150-250degreesC for 5-10 minutes to obtain sulfonamide-silver compound doped graphene, (2) adding zinc powder and fumed silica into active diluent and stirring at a low speed at a low speed, where the rotating speed is 250-350 revolutions per minute, the stirring time is 20-30 minutes, stirring evenly, adding the sulfonamide-silver compound doped graphene, and stirring at a low speed, where the rotation speed is 250-350 revolutions per minute, ultrasonically dispersing for 1-1.5 hours and cooling with circulating cooling water so that the temperature maintains to 25-30degreesC to obtain sulfonamide-silver compound-doped graphene zinc powder slurry, and(3) mixing the epoxy resin, alkyd resin and reactive diluent evenly at low speed, adding vegetable oil fatty acid, pigment and filler, pentaerythritol and mixing evenly at low speed, where the rotating speed is 250-350 revolutions per minute and the fineness is below 50 microns after being ground by a sand mill, then adding the sulfonamide-silver compound doped graphene zinc powder slurry, stirring at high speed at 650-850 revolutions per minute for 35-45 minutes, stirring, filtering and test qualifying to obtain final product.
