Abstract

The invention discloses an environment-friendly type solar thermal-insulation building material. The environment-friendly type solar thermal-insulation building material is characterized by being obtained by mixing, foaming and curing the following raw materials in parts by weight: 120-140 parts of a polyether foaming agent, 50-70 parts of polyether polyol I, 35-50 parts of polyether polyol II, 3-6 parts of expanded vermiculite, 5-8 parts of nano silicon dioxide, 10-20 parts of monochlorodifluoroethane, 5-6 parts of dimethyl methylphosphate, 1-5 parts of diethanol monoisopropanolamine and 1-5 parts of an organic silicon foam stabilizer, wherein the polyether polyol I is lignin polyether polyol, and the polyether polyol II is polyether polyol which is polymerized by taking modified peanut oil as an initiator and by taking epoxypropane as a polymerization monomer. Indexes such as a heat conduction efficient, compressive strength, tensile adhesive strength, dimension stable performance and porosity by closed pore of the environment-friendly type solar thermal-insulation building material are obviously improved in comparison with those of a current thermal-insulation building material; and the environment-friendly type solar thermal-insulation building material is a thermal-insulation building material which is free of phenomena such as shrinkage, deformation, expansion and cracking under a freezing or high-temperature condition, and is excellent in performance.
