Abstract

The invention relates to the technical field of powder coating preparation, and discloses a novel imitation electroplating powder coating and a preparation method thereof. The novel imitation electroplating powder coating is prepared from, in parts by weight, 83-98 parts by weight of epoxy resin, 85-100 parts by weight of polyester resin, 54-72 parts by weight of polyvinyl acetal, 63-90 parts by weight of polycarbonate resin, 1-3 parts by weight of leveling agent, 3-5 parts by weight of gloss enhancer, 2-3 parts by weight of antioxidant, 6-12 parts by weight of soft kaolin, 10-20 parts by weight of aluminum powder, 2-5 parts by weight of benzoin, 5-8 parts by weight of an aluminum powder orienting agent and 0.5-2.5 parts by weight of highlight wax. The novel imitation electroplating powdercoating prepared according to the technical scheme is uniform in coating surface distribution, relatively good in corrosion resistance, acid and alkali resistance, adhesiveness, mechanical property,wear resistance and impact resistance, and obvious in metallic luster in use.

Description

technical field [0001] The invention relates to the technical field of powder coating preparation, in particular to a novel imitation electroplating powder coating and a preparation method thereof. Background technique [0002] Powder coating is a new type of solvent-free, 100% solid powder coating, which has the characteristics of no solvent, no pollution, recyclable, environmental protection, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. It has the characteristics of energy saving, no VOC emission, good decoration, and safe use. In recent years, powder coating technology has developed rapidly. Powder coating is used as a decorative material. With the affluence of life, people are no longer limited to a single color requirement for powder coating coating. Bonding powder coatings with a metallic appearance are recognized as high-end products in the field of powder coatings. They are well received by home appliances, ...
