Abstract

The invention relates to the technical field of materials, and specifically discloses a modified white graphene composite anticorrosion coating, the raw materials of which include by weight: 18-68.5 parts of matrix resin, 5-20 parts of pigment and filler, 0.4-1.5 parts of dispersant, Foaming agent 0.1-0.5 parts, solvent 20-30 parts, white graphene 1-20 parts, curing agent 0-10 parts. The anti-corrosion coating of the composite modified white graphene of the present invention has excellent anti-corrosion performance, has both high strength and salt spray resistance, and the modified white graphene with atomic thickness can further reduce the coating thickness and increase the adhesion to the substrate , improve the wear resistance of the coating. Its anti-corrosion performance exceeds that of existing heavy-duty anti-corrosion coatings. Because of its true green and environmental protection functions, it can be widely used in coating protection in marine engineering, transportation, large-scale industrial equipment, and municipal engineering facilities.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a modified white graphene composite anticorrosion coating and its preparation. Background technique [0002] Metal materials play an important role in human life. In industrial production, metal structural parts are easily corroded due to exposure to high-temperature gas, moisture and smoke all year round, which significantly reduces the mechanical properties of metal materials and destroys the geometry of metal structural parts. Shorten the service life of the equipment and cause huge economic losses. Therefore, looking for effective technical means to realize the anticorrosion of metal materials has become the goal that countries around the world pay attention to. [0003] Among the many anti-corrosion technologies, the anti-corrosion technology of coatings is the most widely used. Anti-corrosion coating is the best material for protecting metal structural parts from corros...
