摘要 使用传统方法检测材料质量的聚合物水泥防水材料在其应用于瓷砖粘结体系中时常常发生开裂或掉砖的问题。因此采用新型的桥接裂缝能力以及拉伸粘结性能检测方法,可以在材料制备时有效预测其应用性能。通过宏观和微观方法重点研究了不同种类聚合物乳液复配对防水涂膜性能的影响,结果表明:苯丙乳液与醋酸乙烯-乙烯共聚乳液以1∶1的质量比复配可以提高涂膜的桥接裂缝能力,改善其抗基层开裂能力,有效避免渗漏水;同时,其拉伸粘结强度相对纯苯丙乳液提高了10.9%,抗瓷砖掉落能力也得到了提高。从整个体系来看,瓷砖粘结剂层和防水层是承担应力的主要部位,中心靠近瓷砖部位的位移和应力最大,并向四周递减。当加载外力时,中部最容易发生破坏。

Abstract: Cracking and brick loss often occur when polymer cement waterproof material tested by traditional methods is applied to ceramic tile bonding system.In this regard, the new testing methods of crack bridging ability and tensile adhesive strength can effectively predict the application performance of the material during preparation. The effects of different polymer emulsions on the performance of waterproof coatings were studied by macro and micro methods. The results showed that when the mass ratio of SA and VAE was 1∶1, it can improve the crack bridging ability of the coatings and effectively avoid water leakage. At the same time, the tensile adhesive strength of the emulsion is 10.9% higher than that of the pure styrene-acrylic emulsion. From the perspective of the whole system, the ceramic tile adhesive layer and the waterproof coating layer are the main parts that bear the stress. The displacement and stress near the ceramic tile are the largest and decrease to the surrounding. The middle section is most prone to failure when external forces are applied.
