External wall thermal insulation anti-cracking polymer mortar and preparation method thereof
The invention discloses an external wall thermal insulation anti-cracking polymer mortar and a preparation method thereof. The external wall thermal insulation anti-cracking polymer mortar is prepared from, by weight, 30 to 50 parts of Portland cement, 10 to 30 parts of a polymer composite emulsion, 5 to 15 parts of an anti-cracking filler, 5 to 10 parts of fly ash, 10 to 30 parts of water, 1 to 2 parts of a water reducing agent and 20 to 35 parts of mixed sand. The anti-cracking filler and the mixed sand are added into a stirrer, and are stirred for 3 min to prepare a mixture; and 2, 2-dimethylolbutyric acid, poly(1, 4-butanediol adipate) and the like are mixed, trimethylolpropane monoallyl ether is used as a coupling agent, a polyurethane emulsion is prepared, then the primary emulsion is added and mixed uniformly to prepare the composite emulsion, the primary emulsion can endow the composite emulsion with excellent cement-based stability, and the prepared composite emulsion has excellent heat resistance.
本发明公开一种外墙保温抗裂高分子砂浆及其制备方法，包括如下重量份原料：30‑50份硅酸盐水泥，10‑30份高分子复合乳液，5‑15份抗开裂填料，5‑10份粉煤灰，10‑30份水，1‑2份减水剂，20‑35份混合砂；将抗开裂填料和混合砂加入搅拌机中搅拌3mi n，制得混合料；将2,2‑二羟甲基丁酸和聚己二酸‑1,4‑丁二醇酯等混合，三羟甲基丙烷单烯丙基醚作为偶联剂，制备出一种聚氨酯乳液，之后加入初乳液，混合均匀，制备出复合乳液，初乳液能够赋予该复合乳液优异的水泥基稳定性，而且该制备出的复合乳液具有优异的耐热性。
