Effect of Sunscreen Additive on the Thermal Insulation Performance of Vacuum Insulation Panel

摘要：

　　Heat transfer through vacuum insulation panels (VIPs) is usually contributed to by solid heat conduction of core material,gas heat conduction,heat radiation and so on.Under vacuum state,heat radiation is the main factor on affecting the thermal conductivity performance of products.In this paper,the core materials doped with different kinds of sunscreen agents were prepared by wet method and the thermal conductivity was also studied.It was found that sunscreen particles on the surface of glass fiber by scanning electron microscopy can effectively absorb infrared light.The influence of different amount of TiO2 additive on the thermal insulation performance of VIPs was further evaluated.Consequently,it turned out that the thermal conductivity of VIP reached the lowest value of0.00168 W/(m· K) when the amount of TiO2 additive was 5% and the internal pressure was 0.1Pa.Moreover,the addition of nanoparticles can increase the specific surface area of core material,which can also prolong the service life of the VIPs.
