为了更好地了解纳米TiO 2（NT）对聚合物-硫铝酸盐水泥复合涂层（PSCC）的影响，系统研究了NT对PSCC的流变性能、力学性能、防水性能和光催化性能的影响。结果表明，NT不仅能改善PSCC的加工性能和力学性能，而且能赋予PSCC良好的光催化性能。NT的最佳含量为0.4- 0.6%。它可以提高流变性能，从而导致更好的和易性。NT作为活性中心，可以优化聚合物与水泥水化之间的网络结构，使PSCC的粘结强度和抗拉强度分别提高59%和25%。吸水率降低17.6%。当NT含量为0.6%时，PSCC在紫外光照射下5 h，RhB的降解率可达76.1%。因此，NT改性PSCC具有柔韧性和刚性兼备、优异的防水性能和良好的光催化性能。
To better understand the effect of nano-TiO2 (NT) on polymer-sulphoaluminate cement composite coating (PSCC), the rheological, mechanical, water-repellent and photocatalytic properties were systematically investigated. The results reveal that NT can not only improve the workability and mechanical properties but also give PSCC satisfactory photocatalytic property. The optimum content of NT is 0.4–0.6%. It can enhance rheological properties leading to a better workability. NT, as an active site, can optimize network structure between polymer and cement hydration, leading to bond and tensile strength of PSCC increase by 59 and 25%, respectively. Moreover, it can sharply decrease the water absorption by 17.6%. In addition, the RhB degradation ratio of PSCC can reach 76.1% under 5 h UV radiation when the content of NT is 0.6%. Therefore, PSCC modified by NT has such advantages as both flexibility and rigidity, excellent water-repellent property and promising photocatalytic property.
