Problems solved by technology
For vacuum insulation panels, its excellent thermal insulation performance is suitable for use in all thermal insulation fields. However, due to the limitation of its use temperature, it can only be used in household appliances such as refrigerators, freezers, water heaters, and cold chains such as containers and refrigerated boxes. Logistics cannot be used for thermal insulation in smelting, aerospace, chemical industry, etc. In order to expand the application field of vacuum insulation panels, it is necessary to solve the environmental restrictions of its use and prolong its life.

Abstract
The technical problem to be solved by the invention is to provide a high-temperature-resistant vacuum insulated panel which is wider in application range and capable of effectively increasing the heat-resistant temperature and a preparation method thereof. The high-temperature-resistant vacuum insulated panel comprises a core material, an adsorbent and a vacuum barrier film material, and the vacuum barrier film material comprises a high-temperature-resistant layer, a metal layer, a gas and oxygen barrier layer and a heat sealing layer. The high-temperature-resistant layer of the vacuum barrier composite film of the high-temperature-resistant vacuum insulated panel adopts a polyimide film, has outstanding high-temperature resistance, radiation resistance, chemical corrosion resistance and electric insulation performance, can be used in air at 250-280DEG C for a long time, can reach the high temperature of 400DEG C in a short time, and greatly widens the application range and the application field; and secondly, the polyimide film is compounded with the aluminum foil, so that the radiation resistance and the gas barrier property of the whole film material are enhanced, and the service life of the high-temperature-resistant vacuum insulated panel is greatly prolonged. The high-temperature-resistant vacuum insulated panel is suitable for popularization and application in the vacuum insulation field.
Description
technical field [0001] The invention relates to the field of vacuum heat insulation, in particular to a high temperature resistant vacuum heat insulation panel and a preparation method thereof. Background technique [0002] Vacuum insulation panel (VIP board) is the abbreviation of Vacuum Insulation Panel in English. It is a kind of vacuum insulation material. It is composed of filling core material and vacuum protection surface. The coefficient can be greatly reduced, as low as 0.0015w / m.k, and it does not contain any ODS materials. It has the characteristics of environmental protection and high efficiency and energy saving. It is currently the most advanced high-efficiency thermal insulation material in the world. [0003] Vacuum insulation panels generally include a core material, a vacuum barrier composite film and an adsorbent. The adsorbent is placed in the core material, and the vacuum barrier film wraps the core material. After vacuum packaging, it becomes a vacuum i...
