Polymer anti-cracking waterproof thermal insulation mortar
The invention discloses polymer anti-cracking waterproof thermal insulation mortar. The polymer anti-cracking waterproof thermal insulation mortar comprises the following raw materials in parts by weight: 100-120 parts of Portland cement, 20-30 parts of gypsum, 120-250 parts of fine sand, 50-100 parts of coarse sand, 5-10 parts of redispersible latex powder, 20-30 parts of modified polyphenyl particles, 10-20 parts of a polyacrylate emulsion, 1-3 parts of sodium dodecyl benzene sulfonate, 1-3 parts of starch ether, 1-3 parts of cellulose ether, 10-20 parts of water, 5-8 parts of an early strength agent, 5-8 parts of a volume stabilizer and 1-3 parts of a thixotropic agent. The volume stabilizer is selected from one or a mixture of more than two of ettringite expansive agents, calcium oxideexpansive agents or magnesium oxide expansive agents. According to the anti-cracking waterproof thermal insulation mortar, through selection and content adjustment of the raw materials, the mortar material is good in cohesiveness and high in stability, has good pump-out form keeping capacity and cohesiveness and is suitable for 3D printing buildings, and the printed buildings have good form and volume stability.
本发明公开了一种聚合物抗裂防水保温砂浆，包括以下按重量份数计的原料：硅酸盐水泥100‑120份，石膏20‑30份，细砂120‑250份，粗砂50‑100份，可再分散乳胶粉5‑10份，改性聚苯颗粒20‑30份，聚丙烯酸酯乳液10‑20份，十二烷基苯磺酸钠1‑3份，淀粉醚1‑3份，纤维素醚1‑3份，水10‑20份，早强剂5‑8份，体积稳定剂5‑8份，触变剂1‑3份。所述的体积稳定剂选自钙矾石类膨胀剂、氧化钙类膨胀剂或氧化镁类膨胀剂中一种或两种以上的混合物。本发明抗裂防水保温砂浆通过原材料的选择和含量调整，砂浆材料粘结性好，稳定性强，具有良好的出泵形态保持能力和粘结性能，适用于3D打印建筑物，打印的建筑物具有良好的形态和体积稳定性。
