Vacuum insulated panel with installation holes and no fear of surface damage

Abstract

The invention discloses a vacuum insulated panel with installation holes and no fear of surface damage. The vacuum insulated panel includes at least two vacuum insulated structure layers, namely an inner vacuum insulated structure layer and at least one outer vacuum insulated structure layer wrapping the outside of the inner vacuum insulated structure layer, the inner vacuum insulated structure layer includes an inner core plate, the inner core plate is provided with an installation groove with a suction material, the installation groove is internally provided with the suction material, an inner high barrier air film bag sleeves the outside of the inner core plate with the suction material, and the inner high barrier air film bag with the inner core plate is vacuumized and heat-sealed by high-vacuum equipment to be made into the inner vacuum insulated structure layer; and the outer vacuum insulated structure layer is made from an outer core plate and an outer high-vacuum barrier air film bag wrapping the outside of the outer core plate by being vacuumized and heat-sealed with high-vacuum heat-sealing equipment, and the inner core plate and the outer core plate are provided with aninner installation hole and an outer installation hole with the positions corresponding to each other correspondingly. After the surface is damaged, the vacuum insulated panel does not bulge, expand or absorb water, and can retain the heat preservation and insulation properties.

Description

technical field [0001] The invention relates to the technical field of heat preservation, heat insulation and fireproof boards, in particular to a vacuum heat insulation board provided with installation holes and 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 e...

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

And because the vacuum insulation board cannot be directly drilled, and then the vacuum insulation board is fixed on the wall or other objects, this will cause the vacuum insulation board to leak air, thereby losing the effect of heat preservation and wind heat
