Problems solved by technology

[0002] At present, the high-gloss products on the market are mainly two-component acrylic polyurethane coatings and amino baking varnishes. The comprehensive cost of the two coatings is very high for customers, and the existing alkyd topcoats dry slowly, and the fullness of acrylic topcoats is not enough. Meet the requirements of customers with high requirements on appearance

Abstract

The invention relates to the technical field of coating preparation, in particular to a preparation method of a low-temperature baking highlight high-performance coating. The coating is suitable for acoating with high gloss requirements and no achievement of the baking temperature of amino groups. Through a reasonable formula, not only can the characteristics of gloss retention and color retention of acrylic coatings be achieved, but also the characteristics of good adhesion of an epoxy system to multiple metal-based substrates can be achieved; and meanwhile when the resin is selected, the coating film can have excellent performance through cooperation with suitable additives.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a preparation method of low-temperature baking high-gloss high-performance paint, which is suitable for paints that require high gloss but cannot reach the temperature of amino baking varnish. Background technique [0002] At present, the high-gloss products on the market are mainly two-component acrylic polyurethane coatings and amino baking varnishes. The comprehensive cost of the two coatings is very high for customers, and the existing alkyd topcoats dry slowly, and the fullness of acrylic topcoats is not enough. Meet the requirements of customers with high requirements on appearance. Contents of the invention [0003] Aiming at the above problems, the present invention provides a low-temperature baked high-gloss high-performance coating and a preparation method. [0004] Technical scheme of the present invention is: [0005] A low-temperature baking high-gloss ...
