Aerogel heat insulation and preservation board

The utility model relates to the technical field of thermal insulation materials, in particular to a heat preservation board. An aerogel heat insulation and preservation board comprises a heat preservation board body, wherein the heat preservation board body comprises a silica gel network and a nanofiber network, and the silica gel network and the nanofiber network composite to form the heat preservation board body. Due to the fact that the technical scheme is adopted, the heat preservation board body is obvious in heat preservation effect, the material integral structure is good, compressive strength is high, performance is stable, and the service period is long.
