Problems solved by technology

[0005] These two methods are all carried out with two sprays and two bakes, which have the following defects: (1) the process is complicated, and the primer must be sprayed first, then polished after drying, and then sprayed with a top coat, so that the production efficiency is low; (2) Both are primer and topcoat two coats, the amount of paint used is high, and the cost is high; with the rise of raw material costs and the intensification of market competition, customers urgently need a single-coat product to replace the current double-coat product. This can greatly reduce the cost of raw materials and production costs, improve production efficiency and market competitiveness, and at the same time comply with the national energy conservation and environmental protection policy, and reduce physical injuries to painting workers

Abstract

The invention relates to a high-solid volume, single-coating and high-lustre black plastic paint and a preparation method thereof. The plastic paint comprises the following components: 30-40wt% of saturated polyester resin, 35-45wt% of hydroxy acrylic resin, 2-4wt% of high-purity carbon black pigment, 1-3wt% of carbon black dispersing agent, 0.5-1wt% of flatting agent, 0.3-0.6wt% of scratch-resisting agent, 0.2-0.5wt% of defoaming agent, 0.02-0.04wt% of drier and 15-25wt% of organic solvent. Compared with the prior art, the black plastic paint has the advantages of low cost, high efficiency, good effect and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a high-solid single-coat high-gloss black plastic paint and a preparation method thereof. Background technique [0002] Among the low-temperature plastic paints currently used in the automobile, home appliance and 3C industries, there is a kind of high-gloss black plastic paint widely used on ABS and other plastics, because its full appearance is similar to the black paint on the surface of a piano, and the industry also calls it "" "Piano black", the traditional coating process of this kind of paint is two coats, generally there are two methods: [0003] Black primer + clear varnish [0004] Primer + Black Topcoat [0005] These two methods are all carried out with two sprays and two bakes, which have the following defects: (1) the process is complicated, and the primer must be sprayed first, then polished after drying, and then sprayed with a top coat, so that the production efficiency is low; (2...
