Abstract

The invention relates to waterborne brilliant UV-curable aluminium paint, a preparation method and an application method thereof, in order to solve the problems of unsmooth surface of electroplated workpieces, low luster, bad adhesive force, bad wear resistance, and the like, and belongs to the field of environmentally friendly aluminium paint. The aluminium paint mainly comprises the following components in parts by mass: 65-95 parts of waterborne UV-curable polyurethane acrylate, 0.05-0.5 parts of a wetting agent, 0.05-0.5 parts of a levelling agent, 2-10 parts of a thickening agent, 0.5-3.5parts of a photoinitiator, 0.05-0.5 parts of an antifoaming agent, 0.1-3.0 parts of dimethyl ethanolamine, 1-6 parts of water, and 2-14 parts of aluminium slurry. The aluminium paint can be used forcoating the surface of a household electrical appliance plastic part, and the paint film has the characteristics of good aluminium powder arrangement effects, high luster, high hardness and high wearresistance.

Description

technical field [0001] The invention belongs to the field of environment-friendly aluminum powder paint, and specifically relates to a water-based bright UV-curable aluminum powder paint; in addition, the invention also relates to a preparation method and a use method of the water-based bright UV-curable aluminum powder paint. Background technique [0002] Aluminum powder paint is a paint containing aluminum powder. Due to the good ductility of aluminum, a continuous aluminum film can be formed in the coating film, which can cover pinholes and reduce permeability. [0003] The traditional aluminum powder paint coating is generally based on solvent-based coatings. Usually, the paint material for the production of aluminum powder paint is composed of alkyd resin, solvent and aluminum powder paste, and alkyd resin is composed of polybasic acid, monobasic acid and polybasic acid. Alcohol and other raw materials are produced by esterification reaction in the resin reactor. The s...
