Preparation method of high-strength thermal insulation mortar
The invention discloses a preparation method of high-strength thermal insulation mortar, and belongs to the technical field of building material preparation. The preparation method comprises the following steps: S1, mixing Portland cement, fly ash, limestone powder, polystyrene particles, bentonite, a thickening agent, heavy calcium carbonate powder, a tackifier and carboxyethyl methyl cellulose in parts by weight, and uniformly stirring to obtain slurry; S2, adding lauryl sodium sulfate into the slurry while stirring, stirring for 10 to 15min, and standing for 30 to 60min; and S3, adding calcium fluoride, a styrene-maleic anhydride copolymer or an organic silicon-polyurethane copolymer, sodium carbonate and hydrochloric acid on the basis of the step S2, and performing uniform stirring with a stirrer so as to obtain the high-strength thermal insulation mortar. The high-strength thermal insulation mortar can improve the compressive strength and reduce the dry apparent density, the heatconductivity coefficient and the volume water absorption rate.
本发明公开了一种高强度保温砂浆的制备方法，属于建筑材料制备技术领域。包括以下步骤：S1：按重量份取硅酸盐水泥、粉煤灰、石灰石粉、聚苯乙烯颗粒、膨润土、增稠剂、双飞粉、增粘剂、羧乙基甲基纤维素混合，搅拌均匀制得浆体；S2：在浆体中边搅拌边加入十二烷基硫酸钠，搅拌10‑15min后静置30‑60min；S3：在步骤S2的基础上添加氟化钙、苯乙烯马来酸酐共聚物或有机硅‑聚氨酯共聚物、碳酸钠、盐酸，用搅拌机搅拌均匀，制得高强度保温砂浆。本发明的高强度保温砂浆能够提高抗压强度，降低干表观密度、导热系数和体积吸水率。
