Plastic-spraying coating for plastic-spraying of bakelite products and spraying method thereof

Abstract

Disclosed are plastic spray coating used for the plastic spray of the hard pressing rubber article and a spray painting method, relating to the plastic spray field of the hard pressing rubber article;the plastic spray coating is composed of 45-95 g of epoxy resin, 45-95 g of polyester resin, 2.5-4.4 g of PV polyurethane, 2.2-6.5 g of luster-coating agent, 0.9-2.8 g of benzoin, 15-24 g of barium sulfate or calcium carbonate, 35-75 g of titanium pigment powder, 0.96-2.5 g of LOP curing agent, 2-4 g of T105 curing agent, 0.6-1.9 g of N325 accelerant, 0.1-0.5 g of T anti-yellow agent and 0.5-0.9g of leveling agent. The coating and the spray painting method has the advantages of simple plastic spray process, sanitary, environmental friendly, low cost and less operators, consistent color on the surface of the hard pressing rubber article after plastic spray treatment, high glossiness, flatness, repeated spraying and high utilization rate of the plastic spray coating; after the plastic spray coating is used; compared with the painting, the treatment speed is improved by 1-2 times; the cost is reduced by one third; the number of the operators is reduced by a half.

Description

technical field [0001] The invention relates to the field of plastic spraying of bakelite products, in particular to a plastic spray coating and a spraying method for plastic spraying of bakelite products. Background technique [0002] The surface treatment of bakelite products in the prior art, such as the surface treatment of sandwich bakelite shells, has been using a paint spraying process, and there is no technical document detailing how to spray plastic on the surface of bakelite products. There are the following problems in the paint spraying process: 1) it is easy to cause harm to the human body, 2) the air pollution is serious, 3) affected and restricted by weather conditions: the same paint spraying process is adopted in low temperature and high temperature environments, but the obtained The product appearance and smoothness of Bakelite products are not the same, and the gloss brightness is not easy to meet the uniform requirements, and it is easy to cause defective...

AI Technical Summary

Problems solved by technology

There are the following problems in the paint spraying process: 1) it is easy to cause harm to the human body, 2) the air pollution is serious, 3) affected and restricted by weather conditions: the same paint spraying process is adopted in low temperature and high temperature environments, but the obtained The product appearance and smoothness of Bakelite products are not the same, and the gloss brightness is not easy to meet the uniform requirements, and it is easy to cause defective products. 4) The utilization rate of paint coating is small, the cost is high and the benefit is low. 5) The process is complicated and the sewage is difficult to treat. Not conducive to environmental protection
