Abstract

The invention provides an aerogel heat insulation sheet which comprises an aerogel layer and a glue layer coating the outer surface of the aerogel layer; the glue layer covers the whole outer surfaceof the aerogel layer and is prepared from the following raw material components in part by weight: 0.03-1.5 parts of carbon powder, 0.5-5 parts of glass fiber powder, 0.2-5 parts of a flame retardantand 4-35 parts of a structural adhesive. The aerogel heat insulation sheet provided by the invention has the benefits that as the glue layer covers the whole outer surface of the aerogel layer, powderon the surface of an aerogel material is fixed in the glue layer, so that the problem of falling-off of the powder on the surface of the aerogel material is solved. Therefore, the aerogel heat insulation sheet can be applied to the automobile field, and is used as a heat insulation material for an automobile battery, and the problems of pollution and damage to an automobile product due to powderdrop of the aerogel material are effectively solved.

Description

technical field [0001] The invention relates to the technical field of heat insulation, in particular to an aerogel heat insulation sheet. Background technique [0002] Aerogel insulation felt is a material with very good thermal insulation performance at present, which provides new ideas and possibilities for many technical solutions that cannot be achieved by the original traditional thermal insulation materials. Aerogel materials are now widely used in the field of new energy vehicles. The thermal insulation sheets made of aerogel materials are used as thermal insulation materials between batteries. However, the existing aerogel materials have powder erosion on the surface of the product. Drop situation, there is a risk of contamination to automotive products and damage to the system. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the above-mentioned problems, and to provide an aerogel heat insulation sheet, which can effectively sol...
