Study on the Vacuum Insulation Panel Protected by Silicone Rubber

摘要

This paper uses molding process to prepare a new kind of pipe insulation material, called silicone rubber-vacuum insulation panel (SR-VIP), which consists of a silicone rubber layer, a VIP layer and silicone rubber layer, making the composite sandwich structure. The thermal consuctivity of the composite is as low as 0.005 W/m·K. The tensile strength, tear strength, compression strength and compression set of the composite are 7.8MPa, 22N/mm, 65Mpa, 25%, respectively. Compared with traditional foam insulation materials, the composite possesses superior thermal insulating properties and mechanical properties.
