摘　　要：制备了反射隔热弹性涂料,分析了涂膜厚度、颜基比、钛白粉的粒径大小及含量、空心玻璃微珠等对反射隔热弹性涂料的太阳反射比的影响,同时研究了陶瓷粉含量对半球发射率的影响.实验结果表明：当涂膜厚度为480μm,钛白粉含量为30％且粒径为100～800 nm,陶瓷粉含量为4％,空心玻璃微珠含量为10％时,可制得太阳反射比为0.891 4,半球发射率为0.89的高性能反射隔热弹性涂料.The influence of film thickness, pigment/binder ratio, particle size and content of titanium dioxide, and hollow glass bead, etc. on the solar reflectance of reflective heat-in- sulation coatings was investigated. Meanwhile, the influence of ceramic powder content on the hemispherical emissivity was analyzed. The result showed that the high performance reflective heat-insulation coatings comprising titanium dioxide 30wt.% having particle size range of 100 -900 nm, ceramic powder 4wt.% and hollow glass microsphere 10wt.% was prepared and its cured film with thickness 480 μm gave the solar reflectance 0. 891 4 and hemisphere emissivity 0. 89 respectively.
