Problems solved by technology

[0002] The traditional method of airgel heat insulation mat is to directly use the airgel felt of corresponding thickness, and produce it by pressing to the required thickness. This method limits the standardization and consistency of the production of heat insulation mat airgel felt, which is not conducive to air Cost reduction and wide application of gel production
Moreover, the thick airgel felt raw material used in the traditional method is an integral structure, and there are penetrating fibers in the longitudinal direction of the airgel felt, which increases the heat conduction channel in the thickness direction, which is not conducive to the heat insulation of the airgel heat insulation pad.

Abstract

The invention discloses a novel laminated structure aerogel composite heat insulation pad which comprises an aerogel composite heat insulation core material and a packaging film material, and the packaging film material packages the aerogel composite heat insulation core material; the aerogel composite heat insulation core material is of a laminated structure. The laminated structure can be one or more of a winding mode, a folding mode and a direct lamination mode, and the aerogel composite thermal insulation material with the thickness of 0.01-3 mm is directly processed. The laminated heat insulation pad has the following advantages: (1) due to the laminated structure, heat conduction channels between layers are reduced, so that the heat insulation effect of the heat insulation pad in the thickness direction can be improved; (2) through effective lamination combination, aerogel heat insulation pad products with different thickness specifications can be prepared from aerogel felts with standard thicknesses, and standardized production and cost reduction popularization of the aerogel felts are facilitated; and (3) the laminated method used in the invention has better thickness uniformity.
