Abstract

The invention belongs to the technical field of coatings, and particularly relates to an aerogel thermal insulation coating for an aluminum alloy material, a fireproof thermal insulation coating layerfor an aluminum alloy battery pack and an aluminum alloy upper cover of the battery pack. The aerogel thermal insulation coating for the aluminum alloy material comprises the following components (byweight): 30-50 parts of a film-forming agent, 10-20 parts of silicon dioxide aerogel, 0.5-5 parts of a dispersing agent, 0.5-5 parts of a thickening agent, 0.5-5 parts of a defoaming agent, 0.5-5 parts of a flame retardant and 0.5-5 parts of a preservative, wherein the film-forming agent is a water-borne epoxy resin emulsion. The aerogel thermal insulation coating is used as an inner layer, the fireproof coating is used as an outer layer, and the inner layer and the outer layer form the fireproof thermal insulation coating layer for the aluminum alloy battery pack. The coating layer acts on the upper cover of the aluminum alloy battery pack, so that the upper cover of the aluminum alloy battery pack has better fireproof heat-insulating property and can pass an external fire test in GB / T 31467.3.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to an airgel heat-insulating coating for aluminum alloy materials, a fire-proof and heat-insulating coating layer for aluminum alloy battery packs, and an aluminum alloy upper cover for battery packs. Background technique [0002] At present, the lightweight of automobiles, especially new energy vehicles, has become the trend of automobile development, and the lightweight of battery packs is one of the research focuses of researchers. Aluminum alloy material, as a light metal material, has attracted people's attention. However, due to the poor heat resistance of aluminum alloy, when used as a battery pack material, the fire safety performance is poor when the thickness is less than 1.2mm. At present, setting fire-proof and heat-insulating coatings on the surface of aluminum alloy battery packs is one of the effective methods to improve the fire resistance and safety pe...
