The invention discloses fireproof flame-retardant thermal insulation mortar which is prepared from the following raw materials in parts by weight: 80 to 90 parts of Portland cement, 22 to 26 parts ofnatural sand, 20 to 30 parts of refractory material, 9 to 13 parts of self-extinguishing polystyrene particles, 4 to 6 parts of reinforcing filler, 1.5 to 2 parts of vinyl acetate copolymer rubber powder, 0.9 to 1.2 parts of auxiliary agent and 160 to 180 parts of tap water. The invention also discloses a preparation method of the thermal insulation mortar. The refractory material is added into the mortar, the refractory material is modified silicon carbide particles, and the modified silicon carbide has higher density, strength and fire resistance, can be used as a fire-resistant functional substance to improve the fireproof and flame-retardant properties of the mortar, and can also be used as a hard filler to improve the mechanical strength of the hardened mortar; through auxiliary matching of the reinforcing filler and the vinyl acetate copolymer rubber powder, the mechanical strength of the mortar after hardening is enhanced while the flame retardance of the mortar is improved, andthe fireproof flame-retardant thermal insulation mortar with high comprehensive performance is obtained.
本发明公开了一种防火阻燃型保温砂浆，包括如下重量份的原料：硅酸盐水泥80‑90份、天然砂22‑26份、耐火材料20‑30份、自熄型聚苯乙烯颗粒9‑13份、增强填料4‑6份、醋酸乙烯酯共聚物胶粉1.5‑2份、助剂0.9‑1.2份、自来水160‑180份；本发明还公开了该保温砂浆的制备方法。本发明的砂浆中加入了耐火材料，耐火材料为改性的碳化硅颗粒，经过改性后的碳化硅具有更高的致密度、强度和耐火性能，不仅能够作为耐火功能性物质，提高砂浆的防火阻燃性能，而且能够作为硬质填料，提高硬化后砂浆的力学强度；通过增强填料和醋酸乙烯酯共聚物胶粉的辅配，提高砂浆阻燃性能的同时，增强砂浆硬化后的力学强度，得到综合性能高的防火阻燃型保温砂浆。
