NOVELTY - Preparing water-based environmental protection graphene composite coating involves grinding the substrate to remove the surface solder joints, then cleaning with metal cleaner and water, and then blasting the substrate to roughen the surface. The raw materials include 50-60 wt.% water-based resin, 30-35 wt.% water-based silicone emulsion, 0.1-8.5 wt.% inorganic filler, 1-8 wt.% curing agent, and rest is water, mixed the required raw materials according to a quantitative percentage, high-speed stirred, and then ultrasonically dispersed the coating solution. The prepared coating solution is evenly coated on the surface of the substrate, and then dried in the shade at room temperature and then cured at high temperature to obtain product. USE - Method for preparing water-based environmental protection graphene composite coating. ADVANTAGE - The method keeps good hydrophobicity.
