Abstract

The invention relates to graphene anticorrosion flame-retardant coating, comprising, by weight, 55.0-72.0 parts of melamine-modified waterborne acrylic flame-retardant resin, 6.0-20.0 parts of a pigment filler, 1.5-3.0 parts of nano carboxylic graphene, 2.5-9.0 parts of an aid, 2.0-6.9 parts of nano carborundum beads, and 10.0-20.0 parts of deionized water. The graphene anticorrosion flame-retardant coating has good film leveling property during film forming, no sagging occurs, the film forming process is friendly to the environment, and adding extra flame retardants and anticorrosion aids isrequired; the film has good adhesion, corrosion resistance, chemicals resistance, flexibility, flame retardancy and the like; the graphene anticorrosion flame-retardant coating is widely applicable tosurface protection and decoration for furniture, musical instruments, metals and the like.

Description

technical field [0001] The invention relates to an anti-corrosion and flame-retardant coating, in particular to a graphene anti-corrosion and flame-retardant coating, which belongs to the technical field of water-based functional coatings. Background technique [0002] In recent years, in response to the damage and pollution of VOC to the environment, countries have paid close attention to the hazards of VOC and have formulated various regulations to limit VOC emissions. Solvent-based coatings use a large amount of organic solvents in the preparation and construction. The global annual emission of volatile organic chemicals into the atmosphere due to the use of solvent-based coatings is about 5 to 6 million tons, which is very harmful to the environment and operators. With the development of technology and the continuous update of environmental protection requirements, the amount of solvent-based coatings will decrease, while water-based coatings, solvent-free coatings, powd...
