The invention discloses an aerogel heat insulation core material and a high-performance aerogel composite heat insulation pad, the aerogel heat insulation core material comprises an aerogel heat insulation core material and a packaging layer, the aerogel heat insulation core material is packaged by the packaging layer, and the aerogel heat insulation core material is formed by pressing an aerogel part and an adding part; the density of the aerogel heat insulation core material after pressing is 1.1-5 times of the apparent density of the aerogel heat insulation core material before pressing; the mass ratio of the aerogel part is 50-100%, and the mass ratio of the addition part is 0-50%. The aerogel is in a compressed state of mutual close contact, so that gaps among components in the heat insulation core material can be reduced, and heat transfer channels are reduced; the packaging layer enables the aerogel heat insulation core material to be kept in a compressed state, so that the aerogel heat insulation core material has higher stiffness, the heat insulation pad has higher toughness and fracture resistance, the aerogel content is higher, the overall heat insulation and fireproof performance of the product is greatly improved, and the thickness and the size are easy to control.
本发明公开了一种气凝胶隔热芯材、高性能气凝胶复合隔热垫,包括气凝胶隔热芯材和封装层,封装层将气凝胶隔热芯材封装,所述气凝胶隔热芯材由气凝胶部分和添加部分压制而成;所述气凝胶隔热芯材压制后密度是未压制前松装密度的1.1‑5倍;且气凝胶部分的质量占比为50‑100%,添加部分的质量占比为0‑50%。气凝胶处于相互紧密接触的压缩状态,可减少隔热芯材中各组成部分间隙,减少传热通道;封装层使气凝胶隔热芯材保持压缩状态,使气凝胶隔热芯材具有更高的硬挺度,且使隔热垫具有更高的韧性和抗折性,气凝胶含量更高,产品整体隔热及防火性能有较大提升,厚度以及尺寸容易控制。
