NOVELTY - Producing an environmentally-friendly waterproof coating involves taking 90-100 pts. wt. polyurethane resin, 12-16 pts. wt. epoxy resin, 4-10 pts. wt. alkyd resin, 6-10 pts. wt. graphene, 2-3 pts. wt. mica powder, 3-8 pts. wt. active agent, 2-4 pts. wt. film forming additive, 0.1-0.3 pts. wt. antifoaming agent, 2-7 pts. wt. plasticizer, 0.5-1.5 pts. wt. anti-aging agent, 5-20 pts. wt. deionized water. 90-100 pts. wt. polyurethane resin and 4-10 pts. wt. alkyd resin are mixed, and stirred uniformly at a temperature of 40-50 degrees C to obtain a mixed resin for use. 12-16 pts. wt. epoxy resin and 5-20 pts. wt. deionized water are mixed to obtain an aqueous epoxy resin. Ultrasonic cleaning of 6-10 pts. wt. graphene is performed with deionized water. The cleaning time is 25-40 min, and then dried in a dry box at a constant temperature of 65-80 degrees C for 4.5-6 h to complete the cleaning work. USE - Method for producing an environmentally-friendly waterproof coating. ADVANTAGE - The method enables to produce an environmentally-friendly waterproof coating, which has excellent environmental protection performance, is non-toxic and tasteless, does not generate irritating odor on the surface of the coating film after construction, has no effect on the human body, is safe, has good elasticity, flexibility, water resistance and water resistance, coating is denser, the adhesion of the coating to the substrate is enhanced, the impact resistance, abrasion resistance and corrosion resistance of the coating layer are improved, and the service life of the coating is enhanced, coating is stable, tough, and can be firmly bonded to the base surface, resulting in long-lasting effective waterproof protection and coating process is simple, is directly painted, has convenient operation, good hardness and long service life. DETAILED DESCRIPTION - The graphene is washed and added to 2-3 pts. wt. mica powder to the aqueous epoxy resin, heated and stirred for 10-20 minutes at a temperature of 40-45 degrees C to form a filler component. The mixed resin is poured into the stirring tank together with the filler componen, and heated to 60-80 degrees C for stirring to obtain a mixed slurry. 3-8 pts. wt. active agent, 2-4 pts. wt. film forming auxiliary, 0.1-0.3 pts. wt. antifoaming agent, 2-7 pts. wt. plasticizer, and 0.5-1.5 pts. wt. antioxidant are added to the mixed slurry. The temperature is raised to 138-142 degrees C, the rotation speed is adjusted to 400-600 r / min, and the mixture is stirred under constant temperature for 1-2 hours to obtain a finished coating.
