Research Progress of Polyurethane Based Aerogel Insulation Materials

Polyurethane based aerogel insulation material is a new type of thermal insulation which is developed in the field of thermal insulation compared with polyurethane foam material. The organic combination of polyurethane molecular structure and the unique nanoporous three-dimensional network structure can make the polyurethane based aerogel materials have better thermal insulation performance. In this paper, the research status of polyurethane aerogels, polyurea aerogels and polyurethane reinforced inorganic aerogels is introduced, and the research progress of thermal insulation properties of polyurethane based aerogels is emphasized.
