Coating used for electric automobile shell

Abstract

The invention discloses coating used for an electric automobile shell. The coating is prepared from the following raw materials in parts by weight: 15-25 parts of quartz powder, 15-25 parts of vinyl acetate-vinyl chloride copolymer, 4-7 parts of talcum powder, 4-7 parts of ceramic microbeads, 4-7 parts of Propylene glycol monomethyl ether acetate, 4-7 parts of nanoscale aluminum oxide, 3-5 parts of file stearate, 3-5 parts of aluminum-doped zinc oxide, 15-25 parts of calcium stearate, 15-25 parts of chlorophyll, 15-25 parts of graphite, 5-7.5 parts of guar gum ether, 5-7.5 parts of chlorinatedparaffin, 5-7.5 parts of musa textilis nee fibers, 5-7.5 parts of filler, 2-4 parts of a nonionic surfactant, 2-4 parts of a curing agent and 2-4 parts of organosilicon modified polyurethane. The coating disclosed by the invention has the advantages that reasonable raw materials and ratio are selected, all the raw materials are synergistic and supplement each other, adhesion is excellent, closeness is excellent, and a film is compact and rigorous, does not crack or expand and is resistant to high temperature and antistatic, so that the coating is applicable to an electric automobile and the coating has flame retardant property.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a coating for an electric vehicle shell. Background technique [0002] With the development of society, the global energy crisis is intensifying, oil resources are becoming increasingly depleted, air pollution and global warming are becoming more and more serious, and cars, as an indispensable means of transportation for people to travel, usually rely on burning oil to drive, which will aggravate energy and environment. crisis. In this regard, the automobile industry has launched new energy electric vehicles, which can avoid or reduce oil burning, which is conducive to promoting environmental protection and alleviating the shortage crisis of traditional energy sources, and has broad market development prospects. [0003] With the advancement of my country's energy-saving and emission-reduction policies, new energy vehicles have been widely used, especially electric veh...

AI Technical Summary

Problems solved by technology

[0005] (1) Ordinary coatings have poor insulation, and there will be safety hazards when used in electric vehicles;

[0006] (2) Ordinary coatings are not resistant to high temperatures, and will crack, foam and fall off under the sun for a long time;

[0007] (3) Ordinary coatings have poor water resistance and are easily penetrated by rainwater, resulting in internal corrosion;

[0008] (4) Ordinary paint is not resistant to bumps, has poor wear resistance, and poor adhesion. After being accidentally scratched, the paint will fall off, and it will be easily corroded
