Vacuum insulation panel with no fear of surface damage

Abstract

The invention discloses a vacuum insulation panel with no fear of surface damage. The vacuum insulation panel comprises at least two vacuum insulation layers, namely, an inner vacuum insulation structure layer and at least one outer vacuum insulation structure layer covering the outside of the inner vacuum insulation structure layer, wherein the inner vacuum insulation structure layer comprises aninner core plate, the inner core plate is provided with an installation groove of a getter material, the installation groove is internally provided with the getter material, the inner core plate withthe getter material is externally sleeved with an inner high barrier gas film bag, the inner high barrier gas film bag provided with the inner core plate is vacuumized and is heat sealed through a high vacuum heat sealing device to form the inner vacuum insulation structure layer; outer core plates and outer high vacuum barrier films covering the outsides of the outer core plates are vacuumized and heat sealed through the high vacuum heat sealing device to form the outer vacuum insulation structure layers. The vacuum insulation panel with no fear of surface damage has the advantages and the beneficial effects of simple structure, good insulation effect, no bulge, no expansion and no water absorption after the surface is damaged, and can keep the thermal insulation performance good.

Description

technical field [0001] The invention relates to the technical field of thermal insulation, heat insulation and fireproof panels, in particular to a vacuum insulation panel that is not afraid of surface damage. Background technique [0002] With the emphasis on energy saving and emission reduction in various countries, thermal insulation technology has developed rapidly. Among them, vacuum insulation panels, as a new type of thermal insulation material and device, have received more and more attention. Vacuum insulation panels are composed of insulation core materials, high-barrier membranes and adsorbents, among which the high-barrier membranes can effectively reduce gas infiltration into the insulation system, maintain internal vacuum, and maintain product performance. At present, most of the single-layer core board and single-layer barrier membrane structures are used in the market. This structure can prevent gas infiltration to a certain extent, but as time goes by, the m...

AI Technical Summary

Problems solved by technology

At present, most of the single-layer core board and single-layer barrier membrane structures are used in the market. This structure can prevent gas infiltration to a certain extent, but as time goes by, the membrane material will be damaged, and the gas will enter the system and destroy the vacuum structure, resulting in Product thermal insulation failure
