通过一定的工艺将二氧化硅气凝胶分散到改性的硅溶胶当中,并添加轻质隔热骨料和功能型填料制备出具有纳米尺寸的绝热保温涂料。该文通过研究不同二氧化硅气凝胶添加量对涂料隔热性能的影响,并对制得的涂料进行一系列的性能测试。实验结果表明,此纳米绝热保温涂料具有耐高温、低导热系数、隔热性能优异等特点。

Through a certain process, the silica airgel is dispersed into the modified silica sol, and the lightweight thermal insulation aggregate and the functional filler are added to prepare the nano-sized thermal insulation coating. In this paper, through the study of different silica airgel additives on the thermal insulation properties of the paint, and the paint obtained a series of performance tests. The experimental results show that this nano thermal insulation coating has the characteristics of high temperature resistance, low thermal conductivity and excellent thermal insulation.
