AEROGEL LAMINATE AND THERMAL INSULATION MATERIAL
The present invention relates to an aerogel laminate having a structure in which an aerogel layer and a support having a heat ray reflective function or a heat ray absorbing function are laminated.
1 . An aerogel laminate having a structure in which an aerogel layer and a support having a heat ray reflective function or a heat ray absorbing function are laminated.
2 . The aerogel laminate according to claim 1 , wherein the aerogel layer is a layer containing an aerogel having a structure derived from polysiloxane.
3 . The aerogel laminate according to claim 1 , wherein the aerogel layer is a layer prepared by drying a wet gel formed from a sol containing at least one selected from the group consisting of polysiloxane compounds having a reactive group in the molecule and hydrolysis products of the polysiloxane compounds.
4 . The aerogel laminate according to claim 1 , wherein the aerogel layer is a layer prepared by drying a wet gel formed from a sol containing silica particles.
5 . The aerogel laminate according to claim 4 , wherein an average primary particle diameter of the silica particles is 1 nm or more and 500 nm or less.
6 . The aerogel laminate according to claim 1 , wherein the support has a layer composed of a material comprising at least one selected from the group consisting of carbon graphite, aluminum, magnesium, silver, titanium, carbon black, metal sulfates, and antimony compounds.
7 . The aerogel laminate according to claim 1 , wherein the support is an aluminum foil, an aluminum deposited film, a silver deposited film, or an antimony oxide containing film.
8 . A thermal insulation material including the aerogel laminate according to claim 1 .
