Abstract

The invention belongs to the technical field of electrical appliance coatings, and provides a scratch-resistant UV metal gloss coating for electrical appliances and a usage method thereof. The coatingis prepared from the following raw materials: urethane acrylate, carboxylic acrylic ester, epoxy acrylate, phosphate resin, sericite, barium sulfate, metal powder, acetylene black, graphene, perhydropolysilazane, a leveling agent and a photo-initiator. The usage method comprises the following steps: firstly, fully and uniformly stirring the scratch-resistant UV metal luster coating; then, spraying the coating on the surfaces of the electrical appliances; meanwhile, performing UV light irradiation and maintaining in the atmosphere of ammonia to obtain a dense bright-black metal luster coating. Compared with the conventional method, the prepared UV metal gloss coating has the advantages that a dense silicon dioxide membrane is formed during the formation of the membrane through photo-curing, so that the prepared coating has high metal gloss, the texture of the electrical appliances is improved greatly, and the adhesive force of the coating is improved remarkably. The scratch-resistantUV metal gloss coating has superior wear resistance and scratch resistance, and can be widely applied in the fields of electrical appliance coatings.

Description

technical field [0001] The invention belongs to the technical field of electrical appliance coatings, and provides a scratch-resistant UV metallic luster coating for electrical appliances and a use method thereof. Background technique [0002] Electrical plastic accessories are an important component of electrical accessories. They have the advantages of good insulation, light weight, good processing formability and low processing cost. They are widely used in instrumentation and mechanical equipment and other fields. At the same time, electrical plastic accessories also have the disadvantages of poor wear resistance and heat resistance, and easy aging. In order to solve this problem, people spray protective paint on the surface of electrical plastic parts to protect the electrical plastic parts. Due to the smooth surface of electrical plastic parts, the requirements for the adhesion of paint are very high. [0003] At this stage, ordinary coatings used for electrical appl...
