Abstract

The invention discloses red paint for electric vehicles. The red paint comprises primer and finishing paint, wherein the primer is prepared from the following components in parts by weight: 50-60 parts of hydroxyl acrylic resin, 5-8 parts of cellulose acetate, 10-15 parts of transparent red paste, 0.1-0.5 parts of an anti-settling agent, 0.3-0. 8 parts of a leveling agent and 15-25 parts of xylene; the finishing paint is prepared from the following components in parts by weight: 60-70 parts of hydroxyl acrylic resin, 10-15 parts of reflective glass beads, 1-2 parts of an acrylic leveling agent, 0.5-1.0 part of a defoamer, 3-5 parts of an anti-settling agent, 10-25 parts of n-butyl acetate. The red paint for the electric vehicles has the advantages of being smooth, delicate and attractive in paint surface, uniform in reflection, bright in color, and excellent in adhesion and scratch resistance and is not prone to fading.

Description

Technical field [0001] The invention relates to the technical field of electric vehicle production, in particular to a red paint used for electric vehicles. Background technique [0002] In the production process of electric vehicles, a large number of parts such as metals and organics are used. Based on the consideration of increasing the corrosion resistance and aging of the parts, and increasing the aesthetic appearance, it is necessary to spray paint on the outer layer of the parts to form a paint coating. Red is a color often used in electric vehicle coatings. The current red paint has ugly surface, poor dispersion, uneven reflective effect, dark hue, not gorgeous color, and it is easy to be scratched, easy to be environmentally polluted, and bright in color. It is not ideal in terms of weather resistance and gloss, and will fade and change color over time. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art...
