Problems solved by technology

[0004] The existing water-based paints on the market have the following technical bottlenecks: existing water-based paints have problems such as high VOC content, strong odor, and serious pollution; existing paints have some problems such as hardness, low fullness, and poor rust resistance and water resistance; The hardness, rust resistance, water resistance, and fullness of existing water-based coatings are still far behind those of solvent-based products, resulting in poor paint film effects

Abstract

The invention discloses special paint for an environment-friendly water-based motor casing. The paint is prepared from the following components in parts by weight: 12 to 20 parts of water-soluble epoxy ester resin, 11 to 18 parts of polyester polyol resin, 0.3 to 1.2 parts of a neutralizer, 0.2 to 0.8 part of a defoamer, 40 to 56 parts of water, 3.5 to 7.5 parts of a thixotropic agent, 0.15 to 0.5 part of a drier, 0.2 to 0.75 part of a flatting agent, 0.3 to 0.73 part of a thickener, and 13 to 23 parts of aluminum paste. The paint is low in smell, beneficial to environmental protection, high in hardness and good in leveling effect.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to an environment-friendly water-based special paint for electric motor casings and a preparation method thereof. Background technique [0002] In recent years, air pollution has been serious, and smog has had a great impact, especially the discharge of some toxic and harmful gases, which directly lead to environmental pollution. As an environmentally friendly and convenient metal paint, water-based metallic paint has become more and more widely used in recent years, and its cost is low. It has been more and more respected and developed rapidly. [0003] Nowadays, motors are used more and more frequently, and the amount of motors is also increasing. The choice of casing coating is very important, especially in terms of anti-rust and water resistance. [0004] The existing water-based paints on the market have the following technical bottlenecks: existing water-based paints have ...
