以异佛尔酮二异氰酸酯(IPDI)、聚醚二醇(N-210)、二羟甲基丙酸(DMPA)、一缩二乙二醇(DEG)、三羟甲基丙烷(TMP)及纳米氧化锡锑(ATO)浆料为主要原料,制备了稳定的纳米ATO改性水性聚氨酯(APU)乳液.粒径测试及透射电子显微镜观察显示,纳米ATO在水性聚氨酯中分散较好,乳液粒径均小于100 nm;FTIR分析表明,纳米ATO粒子与水性聚氨酯(WPU)间可能存在化学键;热重分析(TGA)测试显示,随纳米ATO添加量的增加,胶膜最大热分解温度逐渐提高,最大提高了约20℃;紫外-可见-近红外吸收及保温性能测试表明,随着纳米ATO添加量的提高,胶膜在800～2 500 nm范围的透过率逐渐降低,但涂层在可见光区透过率均超过70%,热阻率由1.34×10-2m2·℃/W提高至3.17×10-2m2·℃/W.
