Abstract

The invention discloses an art type epoxy resin zinc-rich anti-corrosion powder coating. The art type epoxy resin zinc-rich anti-corrosion powder coating comprises the following raw materials in partsby weight: 40-70 parts of epoxy resin, 3-5 parts of curing agent, 0-35 parts of titanium dioxide, 0-40 parts barium sulfate, 0-1 part of acrylic leveling agent, 0-1 part of acrylic wetting agent, 0-1part of benzoin, 0-1 part of stearic acid, 0-5 parts of flatting agent, 0-1 part of polyethylene wax, 0-1 part of polyamide wax, 0-1 part of defoamer, 0-1 part of polytetrafluoroethylene wax, 0-1 part of electric charge conditioning agent, 0-1 part of organic bentonite, 0-2 parts of catalyst, and 5-40 parts of zinc powder. The art type epoxy resin zinc-rich anti-corrosion powder coating not onlyrealizes the technical effect of anti-corrosion, but also can make a coating layer produce pattern effects of sand pattern, crinkle pattern, hammer pattern, etc., so as to cover the defect caused by unevenness of the substrate surface, therefore, the coating has a very high decorativeness, and is suitable for popularization and application.

Description

Technical field [0001] The invention relates to an art type epoxy resin zinc-rich anticorrosive powder coating, which belongs to the technical field of powder coatings. Background technique [0002] Powder coating is a solvent-free, 100% solid powder coating. It has the characteristics of solvent-free, pollution-free, recyclable, environmental protection, energy and resource saving, labor intensity reduction and high mechanical strength of coating film. In recent years, powder coatings have become more and more important in the field of anti-corrosion due to their safety, efficiency, and pollution-free characteristics. At present, an industrial chain from the production of anticorrosive powder coating raw materials to powder manufacturing and spray application is taking shape. The development of anticorrosive powder coatings and the expansion of application fields have also put forward many new requirements for the production of raw materials and powder formulations. A single p...
