纳米TiO2在保温隔热涂料中的应用

The application of nano-titania in the thermal insulation coatings

通过对膨胀珍珠岩,成膜物等的分析,确定了隔热保温涂料的最佳配方;通过应用纳米TiO2浆料加入涂料,成功解决了涂料的耐候性问题。调整成膜乳液和成膜助剂质量比,应用纯丙乳液获得了一种保温性能良好,耐候性良好的纳米复合隔热保温涂料。经试验证明纳米TiO2浆料在添加量总质量的4%时性能最优。最终测定该保温涂料的导热系数为0.0598W/(m.K)。

High range thermal insulation coating was prepared based on expandedperlite and acrylic resin. With analysis about resin, we confirmed the acrylic resin with high Tg as the coating film. By using nano-TiO2 the coating has the best weather resistance. From our research, the best application value of nano-TiO2 was 4% for the thermal insulation ability materials. Its heat conductivity was 0. 0598 W/（m · K）.
