Problems solved by technology

[0004] At present, the traditional pearlescent red on the market is usually made by mixing pearlescent and ordinary colors, and the chroma cannot be very high. Because the pearlescent and ordinary pigments are mixed together, it cannot show the deep sense of color.

Abstract

The invention discloses an automobile color coating process. The coating process comprises the steps of ED coating, floating coat coating, BC1 metal-color paint layer coating, BC2 transparent color paint layer coating and varnish coating. According to the coating process, the light transmission principle is utilized to improve the red color chroma and the angle-dependent color change degree, so that the red charm degree is increased; an automobile coating line does not need to be changed in a large range, by adding one color paint can, the red color chroma can be greatly higher than that of the existing colors, and the 15-degree chroma of the red color adopting the coating process can reach 90-100 while the 15-degree chroma of the mainstream red color in the market is 50-70. According to the coating process, the existing water-based advanced processes 3C1B and 3C2B are combined so that the energy-saving and environment-friendly effects can be effectively carried out.

Description

technical field [0001] The invention belongs to the field of automobile painting techniques, and in particular relates to an automobile color painting technique. Background technique [0002] Red is the most important color in China, and even the cultural totem and spiritual conversion of the Chinese nation. It represents lively, festive and peaceful in China. [0003] The high-glamor red in the color of the car requires high chroma, and at the same time, it needs to show a sense of luxury through the metallic feeling of different colors at different angles, and show a sense of depth through color transparency. [0004] At present, the traditional pearlescent red on the market is usually made by mixing pearlescent and ordinary colors, and the chroma cannot be very high. Because the pearlescent and ordinary pigments are mixed together, the color depth cannot be displayed. [0005] The traditional water-based 3C1B (2PH) red process is: ED primer layer + middle coat (1PH pre-b...
