Abstract

The invention relates to a plastic surface varnish priming paint. The plastic surface varnish priming paint comprises: 18-25 wt% of thermoplastic acrylic resin, 8-15 wt% of a filling material, 3-8 wt% of a pigment, 1.0-2.0 wt% of an auxiliary agent and 50-70 wt% of a solvent. The plastic surface varnish priming paint of the invention has excellent adhesive force and is applicable to plastic articles such as ABS, PC and the like. The varnish priming paint has easy construction and high solid content; and the coating formed paint film is flat, shining, thick in formed film, high in hardness, good in distinctness of image, and high in wear resistance, and also products with various colors can be provided according to client demands.

Description

Technical field [0001] The invention belongs to the technical field of coatings. More specifically, the invention relates to a plastic surface finishing primer with excellent adhesion. Background technique [0002] At present, the surface of some products, such as the lacquer layer on the surface of plastic products, is divided into a general lacquer layer and a top lacquer layer, such as the surface of household appliances such as televisions, washing machines, and refrigerators. The primer layer is generally formed of a thermoplastic acrylic resin coating, and the top coating layer is generally formed of a UV-curable coating or a two-component polyurethane acrylate coating. The primer layer mainly provides the decorative color of the accessory, while the top paint layer provides surface protection for the primer layer and the entire accessory. [0003] The primer coating used for the surface coating of plastic parts generally contains thermoplastic acrylic resin, pigments and so...
