Title: POLYURETHANE-BASED HIGH-PERFORMANCE COMPOSITE THERMAL INSULATION MATERIAL
Abstract:
Provided is a polyurethane-based high-performance composite thermal insulation material comprising a binding material, foamed polyurethane particles and lightweight sand, with the ratio of the three: 1 kg of binding material : 1 to 9 liters of foamed polyurethane particles : 0 to 4 liters of lightweight sand. The binding material is a cement-based binding material or a gypsum-based binding material; the cement-based binding material comprises components: 40 to 100 of cement and 0 to 60 of admixture; the cement may be silicate cement, sulphoaluminate cement, or alkali slag cement, magnesite cement, magnesium oxychloride cement, magnesium oxysulfate cement and the like; and the gypsum-based binding material is building gypsum. The lightweight sand may be lightweight particle with the combustion property of level A, such as sperlite, vitrified tiny beads, ceramic sand, expanded vermiculite, cenosphere, hollow micro-sphere or the like. The polyurethane-based high-performance composite thermal insulation material has the thermal insulation property and the combustion property with a fire resistance of level A, and thus can be used for building thermal insulation boards or thermal insulation wallboards and has a wide adaptation range.
