水性透明隔热涂料的性能研究

Research on performance of waterborne transparent heat-insulation coatings

以纳米氧化锡锑(ATO)水性浆料和水性聚氨酯(Bayhydrol XP 2593/1)为原料,采用共混法制备纳米ATO/水性聚氨酯复合涂料。研究了纳米ATO用量及涂膜厚度对涂膜力学、热学和光学性能的影响。结果表明,当w(ATO)/w(PU)=1:15时,所制得的纳米ATO/PU涂层硬度为2H,附着力为1级;涂层可见光平均透过率为87.1%;在碘钨灯照射下透明隔热玻璃与空白玻璃木盒内空气温度差约6℃。

A coating with good transparence and heat-insulation performance had been prepared based on nano-ATO slurry and Bayhydrol XP 2593/1. The effect of nano-ATO dosage and film thickness on mechanical performance, heat insulation performance and optical performance were studied. And the results indicated that when nano-ATO/PU weight ratio was 1：15, the hardness of the film was 2H, adhesion was the first,and the average visible transmittance was 87.1. The temperature difference of air inside the wood box was about 6℃.
