Abstract

The invention discloses silicon modified graphene water-based paint which is prepared from the following components in parts by mass: 25 to 60 parts of water-based resin, 0.3 to 1.5 parts of neutralizer, 3 to 12 parts of curing agent, 1 to 20 parts of silicon modified graphene slurry, 0.1 to 2 parts of catalyst and 20 to 35 parts of water. Meanwhile, the invention also discloses a preparation method of the silicon modified graphene water-based paint. The silicon modified graphene water-based paint has excellent corrosion resistance, graffiti penetration resistance and graffiti durability resistance, is not limited by types of film-forming resins, and is low in cost and wide in application range.

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 scenes such as doors, window frames, elevator outer walls, electrical enclosures, curtain walls, and roofs. The original functions of enclosure and protection Advanced 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 means of coating curing, vapor deposition or electroplating evaporation. Compared with methods such as vapor deposition, electroplating and evaporation, which require large equipment investment, single color, and expensive...
