Problems solved by technology

[0004] Although graphene is used as the main modification additive in the coating patents related to the addition of graphene, the simple stirring and mixing method in the preparation method cannot completely and uniformly disperse graphene and other nanoparticles in the coating, so that Graphene and other nanoparticles do not play the role of mutual promotion of waterproof and corrosion resistance, high temperature resistance, weather resistance, alkali resistance, impact resistance and aging resistance, and the best effect of graphene and other nanoparticles has not been realized. Get the best out of graphene and other nanoparticles without maximizing the critical role graphene plays in coatings
