摘要 采用钙质材料A、可溶性硅质料B、膦羧酸类络合剂C等组成活性母料,其与水泥、石英砂混合可以配制成水泥基渗透结晶型防水材料(CCWC),以粘结强度和抗渗性指标确定了活性母料配方与掺量。确定母料最优配比:A掺量为0.5%,B掺量为1.0%,C 掺量为0.45%。通过应用性能试验可知,CCWC的粘结强度最大值为2.48 MPa,具有优异的抗开裂性,2 mm砂浆抹面28 d无开裂,1.5 mm涂层水位下降高度仅0.3 mm;CCWC还具有较好的修补防水性能,且各项指标优于国家标准。

Abstract: Using calcareous material A, soluble silica material B, phosphonic acid complexing agent C and other active masterbatch, mixed with cement, quartz sand can be formulated into cement-based permeable crystalline waterproof material (CCWC), with the bonding strength and the impermeability index determines the active masterbatch formulation and dosage. Determine the optimal blending ratio of masterbatch A is 0.5%, B is 1.0%, and C is 0.45%. Through the application performance test, the maximum bond strength of CCWC is 2.48 MPa, has excellent anti-cracking performance, 2 mm mortar plastering surface has no cracking in 28 d, and the 1.5 mm coating water level drops only 0.3 mm. It has good repair and waterproof performance. The indicators are better than national standards.
Key words:  penetrating crystalline waterproof coating    optimal ratio    bonding strength    repair waterproof
