Vacuum thermal insulation plate with mounting holes and without fear of surface damage and processing technology

Abstract

The invention discloses a vacuum thermal insulation plate with mounting holes and without fear of surface damage and a processing technology. The vacuum thermal insulation plate comprises an inner vacuum structural layer and at least one outer vacuum structural layer wrapped around the outer side of the inner vacuum structural layer, the inner vacuum structural layer is composed of an inner core plate body and a high vacuum barrier film wrapped around the outer side of the inner core plate body, the inner core plate body is prepared from materials such as glass fibers through a carding hot pressing or dispersion wet process and a vacuum technology, and the inner vacuum structural layer is prepared by using high vacuum heat sealing equipment; each outer vacuum structural layer is composed of an outer core plate body and a high vacuum barrier film wrapped around the outer side of the outer core plate body, each outer core plate body is prepared from materials such as glass fibers througha mixing dispersion wet process through a vacuum forming technology, a gettering material can be embedded into each outer core plate body, then each outer core plate body is put into the corresponding high vacuum barrier film, and the outer vacuum structural layers are prepared by using the high vacuum heat sealing equipment; and for mounting hole parts, the mounting holes are separated from thecore plate layers by using partition plates provided with through holes. The vacuum thermal insulation plate does not bulge, does not swell, does not absorb water and can retain the thermal insulationperformance after the surface of the vacuum thermal insulation plate is damaged.

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 with installation holes and not afraid of surface damage and its processing technology. 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 infilt...

AI Technical Summary

Problems solved by technology

This single-layer core board, single-layer high-barrier gas-barrier membrane bag structure vacuum insulation panel, once the surface is damaged, will cause problems such as air leakage, swelling, etc., thus losing the effect of heat insulation and fire prevention. Low impact strength, poor toughness, low surface puncture resistance, and the surface of the high-barrier air-barrier diaphragm bag is not smooth enough after vacuuming
