Description

technical field [0001] The invention belongs to the technical field of metal surface coatings, and in particular relates to a silicon-modified graphene water-based coating and a preparation method thereof. Background technique [0002] With the improvement of people's living standards and the in-depth research of material science, metal materials are more and more used in doors, window frames, elevator outer walls, electrical enclosures, curtain walls, roofs and other scenes. The aluminum, iron and stainless steel are also endowed with colorful decoration and aesthetic functions. The decorative function for metal can be realized by forming a functional film on the surface of the metal substrate by coating curing, vapor deposition or electroplating evaporation. Compared with methods such as vapor deposition and electroplating evaporation, which require large equipment investment, single color, and expensive raw materials, the use of coatings to directly cure the surface of t...
