The invention relates to high-strength thermal insulation mortar and a preparation method thereof. The high-strength thermal insulation mortar is prepared from the following raw materials in percentage by weight: 30 to 50 percent of Portland cement, 20 to 30 percent of honeycomb stone micro powder, 16 to 20 percent of modified wollastonite mineral fiber, 1.6 to 2.2 percent of rubber powder, 0.2 to 0.6 percent of air entraining agent, 1 to 5 percent of polycarboxylate superplasticizer and the balance of water. The modified wollastonite mineral fibers are formed by roasting wollastonite mineral fibers and then spraying and modifying the wollastonite mineral fibers with a finishing agent, the finishing agent comprises polyacrylamide and carboxymethyl starch, and the mass ratio of the polyacrylamide to the carboxymethyl starch is (2-5): 1. The wollastonite mineral fibers are modified through the finishing agent, and the component proportion of the finishing agent is adjusted and designed, so that the strength of the prepared mortar is improved, and meanwhile, the mortar has relatively low heat conductivity coefficient and excellent thermal insulation performance.
本发明涉及一种高强度保温砂浆及其制备方法，所述高强度保温砂浆包括以下重量百分比的原料：硅酸盐水泥30‑50％，蜂巢石微粉20‑30％，改性硅灰石矿物纤维16‑20％，橡胶粉1.6‑2.2％，引气剂0.2‑0.6％，聚羧酸减水剂1‑5％，余量为水；所述改性硅灰石矿物纤维是硅灰石矿物纤维经焙烧后利用整理剂喷淋改性而成，所述整理剂包括聚丙烯酰胺及羧甲基淀粉，所述聚丙烯酰胺与羧甲基淀粉的质量比为2‑5:1。本发明通过整理剂对硅灰石矿物纤维改性且对整理剂的组分配比进行调整设计，使制得的砂浆的强度得以提升，同时砂浆具有较低的导热系数，保温性能优异。
