Abstract

The invention discloses an automobile nano paint, which is mainly made of the following raw materials in parts by weight: 5 parts of acrylic resin, 2-8 parts of polyurethane, 5-15 parts of nano calcium carbonate, and 10-20 parts of nano silicon dioxide. 6-12 parts of polysiloxane, 3-9 parts of hydroxyethyl cellulose, 1-5 parts of montmorillonite, 2-6 parts of titanium dioxide, 8-14 parts of talcum powder, 5-15 parts of kaolin, pigment 1-5 servings. The invention also discloses a preparation method of the automobile nano paint. Compared with the prior art, the automotive nano-coating obtained in the present invention not only has the characteristics of conventional automotive coatings, but also has a higher fire-resistant time, and the carbonized layer formed during combustion is thick, firm and dense inside, and the flame-retardant effect is obviously improved ; In addition, its scratch resistance is also significantly improved, and the VOC emission is small, which effectively reduces environmental pollution.

Description

technical field [0001] The invention relates to an automobile nanometer coating and a preparation method thereof, belonging to the field of chemical coatings. Background technique [0002] With the development of my country's automobile industry, the growth of automobile ownership has provided a huge market development space for my country's automobile coating industry.
