摘要： 利用有机硅改性丙烯酸酯乳液和含氟乳液为基料，制备耐沾污、具有热反射和低导热协同作用的隔热涂料。对成膜物质与颜填料进行了筛选，结果表明，当硅丙乳液(KD-9)/含氟乳液(THV340C)的质量比为90∶10进行复配，选用金红石型二氧化钛为颜料，且其体积浓度为25%~35%时，可以获得性能优异的耐沾污隔热涂料。

Abstract: Using silicone modified acrylate emulsion and fluorine-containing emulsion as binder a heat -insulating coatings，which has the multifunction of contamination resistance，heat reflection and low heat conduction，has been developed.The film forming material and pigments and fillers were screened.The re-sult indicates that when the ratio of silicone modified acrylate emulsion (KD-9) and fluorine-containing emulsion (THV340C) is 90/10(m/m)，rutile titanium dioxide is used as the pigment，and precipitated cal-cium carbonate as filer and PVC is 25% ~35%，a high performance contamination resistant and heat re- flective coatings can be obtained.
