Problems solved by technology

Traditionally, the curing temperature of metal electroplating varnish coatings used for metal electroplating varnish products is above 120°C. If the temperature is lower than this temperature, it will be difficult for the paint film to achieve the high hardness, high adhesion and high wear resistance required by electroplating products. and chemical resistance
In recent years, with the rise of labor wages and logistics costs, manufacturers of metal plating varnish products are eager to produce costs, and explore to reduce the baking temperature of metal plating varnish coatings to reduce fuel and electricity costs. Obviously, it is necessary to maintain the traditional Metal electroplating finish products have good comprehensive performance, and metal plating finish coatings with a curing film-forming temperature of 120°C or above have been difficult to meet market demand

Abstract

The invention discloses a hardware electroplating finishing coating. The hardware electroplating finishing coating is prepared from, by weight, 6-20% of polyaspartic ester, 20-35% of whisker silicon, 0.5-2% of sodium hydrogen phosphate, 2-8% of di-tert-butyl peroxide, 2-8% of acetobutyryl cellulose and 50-60% of acrylic resin.

Description

technical field [0001] The invention belongs to the technical field of hardware processing, and in particular relates to a metal electroplating finishing paint. Background technique [0002] Hardware exists in almost any field of production and life. The prosperity of hardware production drives the rapid development of the metal electroplating processing industry, and also drives the diversification of hardware electroplating and finishing products. Traditionally, the curing temperature of metal electroplating varnish coatings used for metal electroplating varnish products is above 120°C. If the temperature is lower than this temperature, it will be difficult for the paint film to achieve the high hardness, high adhesion and high wear resistance required by electroplating products. and chemical resistance. In recent years, with the rise of labor wages and logistics costs, manufacturers of metal plating varnish products are eager to produce costs, and explore to reduce the b...
