The invention relates to anti-crack bonding mortar, which is prepared by mixing the following raw materials in parts by weight: 130 to 160 parts of cement, 40 to 60 parts of fly ash, 260 to 320 partsof sand, 0.4 to 0.6 part of cellulose ether, 0.1 to 0.2 part of modified starch ether, 2.9 to 3.1 parts of rubber powder, 0.05 to 0.1 part of an air entraining agent, 0.2 to 0.3 part of polyester fiber, 2.0 to 2.4 parts of a thixotropic agent, 3 to 3.4 parts of wood fiber, and 20 to 25 parts of zinc oxide. Compared with the existing bonding mortar, the bonding mortar prepared by the invention is suitable for fabricated buildings in the aspects of bonding strength, crack resistance and waterproof protection period.
本发明涉及一种抗裂粘接砂浆，其特征在于：由以下重量份的原料混合而成：水泥130‑160份；粉煤灰40‑60份；砂260‑320份；纤维素醚0.4‑0.6份；改性淀粉醚0.1‑0.2份；胶粉2.9‑3.1份；引气剂0.05‑0.1份；聚酯纤维0.2‑0.3份；触变剂2.0‑2.4份；木质纤维3‑3.4份；氧化锌20‑25份；本发明的优点在于：经试验，采用本发明制得的粘接砂浆与现有粘接砂浆比较，在粘接强度、抗裂性和防水保护期上更适于装配式建筑使用。
