Abstract

The invention provides an aerogel buffer heat insulation pad for a battery module. The aerogel buffer heat insulation pad comprises a needled felt, an aerogel layer and a glue layer coated on the outer surface of the aerogel layer, wherein a first aerogel layer and a second aerogel layer are respectively arranged on two opposite sides of the needled felt; the glue layer wraps the whole outer surface of the aerogel layer and is mainly prepared from the following raw material components in parts by weight: 0.05 to 1 part of carbon powder, 1.3 to 4 parts of glass fiber powder, 0.6 to 6 parts of aflame retardant, 2 to 8 parts of high-temperature-resistant glue and 7 to 30 parts of structural glue. According to the aerogel buffer heat insulation pad for the battery module, the whole outer surface of the aerogel layer is wrapped by the glue layer, the powder on the surface of the aerogel material is fixed in the glue layer and thus the problem that powder on the surface of the aerogel material falls off is effectively solved, the aerogel heat insulation padcan be applied to the field of automobiles and used as a heat insulation material of an automobile battery, and the problem that automobile products are polluted and damaged due to powder falling of the aerogel material is effectively solved.

Description

technical field [0001] The invention relates to the technical field of heat insulation, in particular to an airgel cushioning heat insulation pad for a battery module. Background technique [0002] Airgel thermal insulation felt is currently a material with very good thermal insulation performance, which provides new ideas and possibilities for quite a few technical solutions that cannot be achieved by the original traditional thermal insulation materials. Airgel materials are now widely used in the field of new energy vehicles.
