热效果和隔热持久性的影响及作用规律。结果表明, 以丙烯酸酯乳液为成膜基料, 二氧化钛质量分数为20%, 空心玻璃
微珠含量为11%, 涂层厚度为11 2mm 时并辅助含氟硅的耐玷污透明涂层, 制备出的热反射隔热涂料的太阳光反射率为
91% , 半球发射率为86%, 均超过了JG/ T235- 20085建筑反射隔热涂料6 行业标准中的技术指标, 且具有良好的自清洁
性能, 项目成果实现了产业化。[英文文摘]The propert ies of heat-ref lect ive insulation coat ings and their inf luencing factors including film-forming
material, insulation pigment , the content of hollow g lass microspheres, coat ing thickness and pollut ion resistant coating
were invest ig ated. The paint w as obtained using acrylic emulsion as the base material and consisted of 20%
amount of pigment , 11% amount of hollow glass microspheres and a pollut ion resistant transparent coat ing. T he film
thickness reached 1. 2 mm and it show ed a good heat-ref lect ive performance w ith the solar ref lectance and hemispher-i
cal emit tance of the prepared paint being 91% and 86%, respect ively. With the assistance of pollution resistant
transparent coat ing containing f luorine and silicon, the prepared paint had a good ability of sel-f cleaning. T he project
achievement has been industrialized. T he ident ificat ion results show that the comprehensive technical performance has
reached the internat ional advanced level of similar products.基金项目: 福建省重大科技平台建设项目( 2009J1009) ; 产学重大专项( 2010H 6021) ; 省基金( 2010J01306
