Problems solved by technology

Because it is difficult to control the directionality of the paint mica particles that are added later, or it is almost impossible to be consistent with the original direction. If the direction is not consistent, the color will be significantly different.

Abstract

The invention provides rapid repair paint for reducing the repair chromatic aberration of a car body and a preparation method of the rapid repair paint. The repair paint comprises the ingredients in parts by weight: 20-40 parts of resin, 20-40 parts of additive resin, 5-10 parts of a metal pigment, 10-20 parts of a copolymer, 5-10 parts of a solvent, and 1-5 parts of an additive. The preparation process is simple, through the application of the obtained repair paint, the repair chromatic aberration of the car body can be reduced effectively, and the repair efficiency can be improved; after repair, particles of metal paint looks more three-dimensional, metallic and brilliant, the product performance is excellent, the hardness is equal to and higher than H, and the adhesive force is 0-1 level.

Description

technical field [0001] The invention belongs to the field of paints, and in particular relates to a rapid repair paint for reducing color difference in car body repair and a preparation method thereof. Background technique [0002] Automotive flash paint has a metallic flash texture, which can improve the grade of the paint film and fully demonstrate the effect of noble and elegant temperament. Flash paint includes metallic paint and pearlescent paint. The monochrome paint reflects the incident light through the pigment particles. Since the scattered light is the main body, there is no color flop effect, so the color difference is easy to control. For metallic paint, when the flake aluminum powder is arranged parallel to the substrate in the paint film, it looks like a small mirror. , different shades of metallic color and sparkle can be observed. The aluminum powder content and the size of the aluminum powder in the metallic paint have a great influence on the lightness....
