Problems solved by technology

[0003] The thickness of the paint film has a great influence on the rust prevention of the metal frame of the vehicle. If the thickness of the paint film is too thick, it will cause waste of paint, thinner, and curing agent, and will cause agglomeration to fall off. The effect, the thickness of the paint film is thin, the paint cannot cover the processed surface of the part or the primer of the part, and a good paint film cannot be formed, the protective effect is poor, and the appearance quality is poor, and the subjective vision for the customer is poor
Existing paint additives are not only expensive but also unable to improve paint utilization efficiency

Abstract

The invention relates to the technical field of functional material research, and discloses a paint composite additive that reduces vehicle painting costs. The prepared paint composite additive has strong modification properties, excellent interface properties and mechanical properties, and can enhance and modify paint Function, generally applicable to various types of vehicle paint, stable combination with film-forming substances, reducing the escape of paint mist during painting, improving the on-site operating environment, improving paint adhesion, good painting effect, and prolonging the coating life. The thickness of the coating is reduced by 10-15 microns, which can save 20-25% of paint, improve the overall appearance quality of vehicle painting, and reduce the cost of painting. The improvement of environment and cost has improved the market competitiveness, and it is a technical solution worthy of popularization and use.

Description

technical field [0001] The invention belongs to the technical field of functional material research, and in particular relates to a paint compounding additive for reducing vehicle painting costs. Background technique [0002] There are generally several types of topcoats used in vehicle painting: ordinary paint, metallic paint, and pearlescent paint. Needless to say, ordinary paint, resins, pigments and additives. The metallic paint has more aluminum powder, so it looks bright when finished. For pearlescent paint, mica particles are added. Mica is a very thin sheet of things, so the reflection is directional, and there is a colorful effect. If it is metallic paint plus a varnish layer, the car's paint looks very bright and beautiful. In terms of color, white is undoubtedly the cheapest. For example, the world-class brand red pigment is about 25 times more expensive than the world-class brand titanium dioxide, and the amount of titanium dioxide in white paint is about 5 ...
