Problems solved by technology

After the ordinary paint is finished with paint, the conductivity cannot meet the conductivity required by the electrostatic equipment, so electrostatic spraying cannot be used
Traditional paint spraying generally adopts brushing or spraying methods for construction, but these construction methods have disadvantages such as low efficiency, too much waste of paint, and serious impact on human health.

Abstract

The invention relates to a polishing varnish for electrostatic spraying and a preparation method thereof. The varnish is prepared from a main agent, a curing agent and a diluent at a ratio of 1-1.2:0.8-1:0.5-0.7, wherein the main The agent components and parts by weight are as follows: 20-25 parts of synthetic fatty acid, 60-66 parts of coconut oil, 11-15 parts of mixed environmental protection solvent, 0.3-0.8 part of leveling agent, 0.1-0.3 part of defoamer; The curing agent is an isocyanate curing agent. The polishing varnish for electrostatic spraying of the present invention can be electrostatically sprayed, and the coating film after spraying has good leveling property and high hardness and can be polished.

Description

technical field [0001] The invention relates to a polishable gloss varnish, in particular to a polishable gloss varnish for electrostatic spraying. Background technique [0002] With the rapid development of modern industry, anti-corrosion is becoming more and more important. One of the effective anti-corrosion methods is to coat a non-metallic protective layer on the surface of the substrate --- coating. After the ordinary paint is prepared with paint, the conductivity cannot meet the conductivity required by the electrostatic equipment, so electrostatic spraying cannot be used. Traditional paint spraying generally adopts brushing or spraying methods for construction, but these construction methods all have shortcomings such as low efficiency, too much waste of paint, and serious impact on human health. Contents of the invention [0003] The object of the present invention is to provide a polishing varnish for electrostatic spraying, which can be electrostatically spraye...
