Environment-friendly high-hardness acrylic acid amino baking varnish and preparation method thereof

Abstract

The invention provides environment-friendly high-hardness acrylic acid amino baking varnish and a preparation method thereof. The environment-friendly high-hardness acrylic acid amino baking varnish comprises the following components: nano TiO2 modified acrylic resin, polyethylene glycol modified amino resin, a titanate coupling agent, a leveling agent, a defoaming agent, a thickening agent, an emulsifier, a pH neutralizing agent, pigment, isopropanol and deionized water. The baking varnish takes the special nano TiO2 modified acrylic resin, the polyethylene glycol modified amino resin and the titanate coupling agent as main components; due to the modified acrylic resin and amino resin, the hardness of a baking varnish membrane can be effectively improved, the adhesion property can be improved, and the corrosion resistance can be improved; the constituting components are reasonably designed, the deionized water is taken as a solvent for dilution, and an organic solvent is replaced, so that the baking varnish is environment-friendly, is good in wear resistance, good in adhesion property, good in ductility, good in high temperature resistance and long in service life; and the baking varnish can be applied in a spraying manner instead of roller painting, is capable of effectively improving the production environment, and is beneficial to body health of operators.

Description

Technical field [0001] The invention relates to an environmentally friendly high-hardness acrylic amino clear baking paint and a preparation method thereof. Background technique [0002] The high temperature baking of the baking paint is lighter, the paint film has better weather resistance, slightly stronger gloss and higher hardness. Synthetic fatty acids are derived from petroleum and are not restricted by vegetable oil resources, so it is a way to save vegetable oil for development and production. [0003] Amino baking paint is a kind of light industrial decorative paint, because the paint film is required to be bright, colorful and full of luster. And most of them are white, light color, color and black. After the paint film is baked at a high temperature (120-180℃), the pigment should not fade or change color; the white pigment does not turn yellow, the pigments of various colors are neutral, have certain chemical resistance, good solvent resistance, and no bleeding , Good...

AI Technical Summary

Problems solved by technology

The main problem in spraying is highly dispersed paint mist and volatilized solvents (i.e. volatile organic pollutants, VOCs), which not only pollute the environment, are not conducive to human health, but also waste baking paint, causing economic losses
