At present, there are only a few manufacturers of chameleon pearl special effect paint in this subdivision field, such as PPG, Duya, Deka, etc. The product cost is high and the price is high, which is difficult for consumers to accept
[0004] Chinese patent CN 102925007 B discloses a car bumper paint with reflective and illusion effects, which is composed of the following raw materials in weight percentage: chameleon pearl paint 2-8, glass powder for reflective paint 6-10, xylene 10- 20. Wetting agent 0.1-1, resin 10-30, cellulose acetate butyrate 30-50, butyl acetate 10-20, this invention is rich in color, with colorful color-changing illusion effect, mainly for automobile rear insurance The key point of the paint developed by the company is that the reflective effect brought by the light irradiation will bring obvious safety warning effect and the color-changing aesthetic effect. However, the invention does not clarify the type and model of chameleon pearls, but focuses on highlighting the reflective effect, and does not change the color of the whole car. The color flop, flicker and chroma of the product are not very ideal

Abstract

The invention relates to automotive special paint containing chameleon pearlescent pigments and a preparation method of the automotive special paint. The special paint is prepared from components in parts by weight as follows: 80-88 parts of intermediates, 0.2-0.8 parts of a dispersing auxiliary, 5.5-8.5 parts of the chameleon pearlescent pigments and 6.8-10.8 parts of a solvent. The special paint is mainly prepared from the chameleon pearlescent pigments, and by means of reasonable formula design, a product has the characteristics of remarkable angle-dependent optical effect, high flickering degree and high chroma. Compared with the prior art, the refinishing paint is good in dispersibility, high in drying speed, good in storage stability, high in chroma after construction, remarkable in angle-dependent optical effect and high in lustrousness, and colors are striking and full; the raw materials are inexpensive, and compared with products of competitors, the special paint has the advantages in the aspect of manufacturing cost, is high in cost performance, has relatively comprehensive varieties and meets the requirements of customers for personalized colors.
