Abstract

The invention discloses an energy-saving environment-friendly solar heat preservation building material. The heat preservation building material is obtained by foaming the following raw materials in parts by weight: 120-140 parts of dimer acid diisocyanate, 50-70 parts of polyether polyol I, 35-50 parts of polyether polyol II, 3-6 parts of expanded vermiculite, 5-8 parts of nanosilicon dioxide, 10-20 parts of chlorodifluoroethane, 5-6 parts of dimethyl methylphosphate, 1-5 parts of ethylene glycol monoisopropanolamine and 1-5 parts of organosilicone foam stabilizer. The energy-saving environment-friendly solar heat preservation building material is obviously improved in indexes such as thermal conductivity, compressive strength, tensile adhesive strength, dimensional stability and close pore ratio compared with an existing heat preservation building material and produces no phenomenon such as shrinkage, deformation, expansion and cracking under the freezing or high temperature condition, so that the heat preservation building material disclosed by the invention is excellent in performance.
