| 摘 要： | 本文通过空心玻璃微珠涂料反射实验、隔热实验和SEM分析研究空心玻璃微珠用量对涂料反射和隔热性能影响,结果表明:空心玻璃微珠的适宜添加量为25%,反射率能达45%-65%,能降温9℃;涂料反射隔热性能主要是由空心玻璃微珠对太阳光具有反射和阻隔作用引起,其次还与空心玻璃微珠在涂层表面的排布有关。在空心玻璃微珠用量为25%时,空心玻璃微珠在涂层中形成由无数空腔形成的致密的阻隔层来反射太阳光和阻止热传导。

| Abstract: | Effects of hollow glass beads on light-reflecting and heat –insulating properties of coating was characterized through the reflection,insulation and scanning electron microscopy(SEM) experiments.The results show that the appropriate amount of hollow glass beads is 25%,the reflectance of coating can reach 45%-65%,the temperature can be reduced by 9℃,the attained heat barrier effect is mainly caused by the reflection and heat insulation of hollow glass beads on sunlight,and it also has something to do with arrangement of hollow glass beads on the surface of coating.When the addition is 25%,hollow glass beads form dense layers composed of countless cavities to reflect sunlight and to prevent heat from conducting. |
