Abstract
The technique set forth in the present specification provides a heat insulation material having functions of enhancing heat-insulating performance and preventing aerogel dispersion by using aerogel granules and a polymer binder. According to an embodiment of the technique set forth in the present specification, the thickness of the heat insulation material is adjustable according to the purpose of the heat insulation material, so that a heat insulation material that can be made into products in various fields is provided.
Claims4
A heat insulation material comprising:
- at least two first substrate layers;
- and
- at least two second substrate layers stacked on at least one of the first substrate layers and comprising aerogel granules,
