High-strength thermal insulation mortar

The invention discloses high-strength thermal insulation mortar which comprises the following raw materials in parts by weight: 30-50 parts of ferro-aluminate cement, 45-65 parts of iron tailing sand, 20-30 parts of polyurethane granules, 5-10 parts of loess, 10-15 parts of attapulgite, 14-18 parts of illite powder, 8-12 parts of waste rubber powder, 4-6 parts of carbon fiber powder, 1-2 parts of sodium caseinate, 2-3 parts of redispersible latex powder, 1.5-2.5 parts of polyvinylpyrrolidone, 1-2 parts of sodium humate, 0.5-1 part of sodium sulfanilate and 4-6 parts of composite fillers. The thermal insulation mortar is relatively high in bonding strength, compressive strength and impact resistance, effectively solves the problems of easy cracking, easy hollowing and the like of conventional thermal insulation mortar, has the advantages of excellent thermal insulation property, whether resistance, water resistance, ageing resistance, corrosion resistance and the like, is completely environmental friendly, simple and convenient to construct and durable, and can be widely applied to building external wall and internal wall insulation systems.
