Large-membrane thickness PE electrostatic-sprayed paint

Abstract

The invention discloses large-membrane thickness PE electrostatic-sprayed paint. The large-membrane thickness PE electrostatic-sprayed paint comprises a main agent part A, a cobalt iso-octoate-containing part B and a methylethyl ketone peroxide-containing part C. The main agent part A comprises, by weight, 60-80 parts of unsaturated polyester resin, 0.01-0.03 parts of a polymerization inhibitor, 10-25 parts of an inorganic filling material, 3-5 parts of zinc stearate, 4-8 parts of a solvent, 0.3-0.5 parts of an anti-settling agent, 0.1-0.3 parts of an antifoaming agent, 0.2-0.5 parts of a leveling agent and 0.1-0.5 parts of a conductive agent which is an alkanolamide solution of nonsaturated acidic carboxylate. The alkanolamide solution of nonsaturated acidic carboxylate reduces paint resistance, improves paint conductivity and satisfies electrostatic-coating resistor requirements.

Description

technical field [0001] The invention relates to a PE paint, in particular to a PE electrostatic spray paint with high film thickness. Background technique [0002] Because of its solvent-free, high solid content, and good filling properties, PE coatings can be coated thickly at one time, with plump coating films, high hardness, excellent chemical resistance, low VOC emissions, and excellent filling properties in solid wood furniture and veneer furniture. The anti-slump performance is unmatched by PU primers. In recent years, it has developed very rapidly. The demand in the Chinese market has increased by 10% per year. It is gradually replacing PU primers and widely used in furniture coating. [0003] At present, the PE coatings on the market are high-resistivity polymers, and most of the development direction is to improve the high-temperature resistance. However, PE resin is a non-polar polymer compound with poor conductivity. The PE coating cannot be adsorbed on the surfa...

Problems solved by technology

[0003] At present, the PE coatings on the market are high-resistivity polymers, and most of the development direction is to improve the high-temperature resistance. However, PE resin is a non-polar polymer compound with poor conductivity. The PE coating cannot be adsorbed on the furniture surface, and the edge of the back part of the furniture cannot absorb PE coating

Most of them are sprayed by compressed air method. In order to reduce the cost, a large amount of inactive thinner is generally added to the thinner to achieve the effect of thin film. When sprayed by air spray method, it is easy to cause paint mist to splash and serious waste of paint, resulting in damage to the Environmental pollution; at the same time, the labor intensity of the operators is high, the efficiency is low, and the labor protection of the operators is not in place, which affects their health. However, the existing PE coating electrostatic spraying construction cannot adsorb the PE coating on the furniture surface, and the edge of the back of the furniture cannot Absorption of PE coatings can not achieve satisfactory use effect
