Anti-aging coating for battery cover plate of new-energy automobile

Abstract

The invention discloses an anti-aging coating for a battery cover plate of a new-energy automobile. The anti-aging coating comprises the following raw materials in parts by weight: 30-40 parts of polysulfide rubber, 20-28 parts of polytetrafluoroethylene gum, 5-8 parts of terpene resin, 3-6 parts of sebacicdihydrazide, 3-6 parts of high-pigment carbon black, 3-6 parts of zinc borate, 0.2-0.3 partof ninhydrin, 0.2-0.3 part of stannous oxide, 0.5-0.8 part of diatomite, 0.5-0.8 part of semi-reinforcing furnace black SRF, 0.2-0.3 part of aluminium nitride, 0.5-0.8 part of shellac, 0.1-0.2 part ofsulfur, 2-3 parts of ethylicin, 0.1-0.2 part of chlorinated paraffin, 0.1- 0.2 part of 1, 2-dimethylimidazole and 0.1-0.2 part of rare earth cerium fluoride. After adoption of a formula, the anti-aging automobile coating has good gloss and color retention and water and chemical resistance, and is fast in drying and convenient to construct; the anti-aging automobile coating has improved light aging resistance and paint film strength.

Description

technical field [0001] The invention relates to the technical field of automobile coatings, in particular to an aging-resistant coating for a battery cover plate of a new energy automobile. Background technique [0002] Automobile coatings refer to the coatings applied on the body and parts of various vehicles such as cars, and generally refer to coatings and auxiliary materials for new cars and coatings for vehicle repairs. [0003] 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 allevi...
