Abstract

The invention provides a solvent-free graphene zinc powder coating, and relates to the technical field of industrial coatings. The solvent-free graphene zinc powder coating is prepared from a component A and a component B in parts by mass, wherein the component A comprises the following components in percentage by weight: 35-50% of epoxy resin, 5-10% of epoxy active diluent, 2-4% of powdered graphene, 0.5-1% of defoaming agent, 2-4% of thixotropic agent, 15-25% of barium sulfate, 8-10% of talcum powder and 5-10% of mica powder; and the component B comprises the following components in percentage by weight: 50% of polyamino amide resin, 10% of mica powder, 0.5% of a dispersing agent, 35% of barium sulfate, 0.5% of a defoaming agent and 4% of a coupling agent. According to the invention, byreasonably selecting the raw materials, the anticorrosive life of the coating is prolonged, the construction is safer, more environment-friendly and more convenient, the coating can be emphatically applied to the oil-gas storage tank, the inner wall of the coating is in direct contact with oil gas without polluting the oil gas, and the coating has excellent electrical conductivity and thermal conductivity, so that the storage tank can transport and store flammable and combustible chemicals more safely.

Description

technical field [0001] The invention relates to the technical field of industrial coatings, in particular to solvent-free graphene zinc powder coatings. Background technique [0002] In chemical storage tanks, pipelines, bridge steel structures, marine engineering equipment, energy and power, equipment manufacturing and other fields, some storage tanks, feeding pipes, and steel structures are often corroded by internal and external environmental media during use, and are prone to create safety hazards. Therefore, it is necessary to spray coatings for effective anti-corrosion. At present, most of the anti-corrosion and static-conductive coatings used on the inner wall of storage tanks are additive oil-based coatings with volatile organic solvents as diluents. During the use of this kind of coating, due to the strong volatility of organic solvents, and some organic solvents are poisonous and harmful, which seriously endanger the health of construction workers and pollute the ...
