A kind of preparation method of front and side side control agent of water-based metallic glitter paint

Abstract

The invention relates to a preparation method of a water-based metal flash paint front and side control agent, which is suitable for the automobile surface repair industry. It discloses adding 70-100 parts by mass of deionized water into the dispersion tank, adding 0.2-1.0 parts by mass of neutralizing agent, 2.0-4.0 parts by mass of dispersant, and 0.5-1.0 parts by mass of disinfectant Foaming agent, after dispersing for 5 minutes, add 18-28 parts by mass of water-based polyamide wax in the dispersed state, disperse at high speed for 10-15 minutes, and control its fineness at 25-30um. Add 15-25 parts by mass of matte powder that disrupts the arrangement in the dispersed state, disperse at high speed for 15-20 minutes, then add 0.2-2.5 parts by mass of water-based bentonite in the dispersed state, and disperse at high speed for 15-20 minutes, Put it into a horizontal sand mill and grind it once, the fineness is controlled at 25-30um, and the dispersion is uniform, which is the finished product. The invention is very suitable for the deployment when the side surface of the water-based metal flash paint is too deep, shortens the preparation time, and accelerates the progress of the project.

Description

technical field [0001] The invention relates to the field of water-based metallic flash paint; in particular, it relates to a preparation method of a water-based metallic flash paint front and side control agent suitable for automobile surface repair. Background technique [0002] (1) In recent years, the sales of automobiles have increased year by year, which has also led to the rapid development of automobile coatings. With the continuous introduction of environmental protection policies and the continuous improvement of people's awareness of environmental protection, automotive coatings are also developing in the direction of environmental protection and health. At present, a clear direction is the water-based coating. Among the automotive topcoats with a variety of colors, the metal flash paint has a special metallic flickering feeling, and the color also changes correspondingly at different angles, that is, the color is strong with the angle, so the metallic flash paint...

Problems solved by technology

At present, the situation that often occurs in water-based metallic glitter paint is that the hue and chroma of the color are basically accurate, but the depth of the color on the front side cannot meet the requirements. Compared with the original car paint sprayed on the car, although it belongs to the same hue, the lightness is off. If it is dark or light, it is necessary to add color paint to adjust the depth. The newly added color paint changes the hue and needs to be toned again, so the material cost and labor cost are increased.
