Problems solved by technology

In addition, in the process of spraying the plastic workpiece with the spray agent obtained by combining the water-based pearlescent silver powder primer and the water-based UV topcoat, it needs to be sprayed at least twice and baked at least twice to achieve the curing effect. The spraying process or processing steps have the disadvantages of being cumbersome and inconvenient, and the time required for processing is long.

Abstract

The invention relates to single-coating water-based UV pearlescent silver powder paint and a preparation method thereof. The single-coating water-based UV pearlescent silver powder paint produced by adopting a formula, a weight ratio and the preparation method disclosed by the invention has the advantages that in the construction process of a workpiece, only one-time spraying and one-time baking are needed; the defect that a traditional process of mixing water-based pearlescent silver powder primer with water-based UV finish paint, and construction on workpieces, at least two times of sprayingcoating and at least two times of baking are needed is avoided; the baking time can be shortened to 8-15 minutes, the construction procedure can be simplified, the baking time can be shortened, and the construction efficiency can be improved; in addition, deionized water can be used as a diluent instead of an organic solvent, so that the use amount of the diluent can be greatly reduced, the problem that the use of the organic solvent is harmful to human health is effectively solved, using is more convenient, and the environment protection performance is better.

Description

technical field [0001] The invention relates to a single-coating water-based UV pearlescent silver powder paint and a preparation method thereof. Background technique [0002] Currently used in Huawei, Gionee, VIVO and other brands of electronic product casings and product frames are processed through the combination of water-based pearlescent silver powder primer and water-based UV topcoat. Because the water-based pearlescent silver powder primer has good decoration And protection, so that it can make pure metal effect and metal effect with various colors, so that its market prospect is very broad. [0003] However, as the environmental protection situation becomes increasingly severe, the environmental protection requirements for coatings will also expand. The use of water-based pearlescent silver powder primers and water-based UV topcoats on the market both emit a large amount of VOC, and the current water-based pearlescent paints on the market The combined use of silver...
