Vacuum insulation board with no fear of surface damage and processing technology

Abstract

The invention discloses a vacuum insulation board with no fear of surface damage and a processing technology thereof. The vacuum insulation board comprises an inner vacuum structural layer and at least one outer vacuum structural layer wrapped outside the inner vacuum structural layer, wherein the inner vacuum structure layer is composed of an inner core plate and a high vacuum barrier film wrapped outside the inner core plate, the inner core plate inner vacuum structure layer is composed of the inner core plate and the high vacuum barrier film wrapped outside the inner core plate, the inner core plate is prepared from a material such as glass fibers through carding hot pressing or dispersion wet method and a vacuum process, the inner core plate and a getter material are placed into the high vacuum barrier film to be made into the inner vacuum structure layer through high vacuum heat sealing equipment, the outer vacuum structure layer is composed of the inner vacuum structure, an outercore plate and a high-vacuum barrier film wrapped outside the outer core plate, and the outer core plate is made of glass fiber and other materials through wet-process mixed dispersion through a vacuum forming process. The vacuum insulation board has the characteristics of being good in heat preservation effect, safe, light, simple in construction, and capable of opening holes and the like, and after the surface is damaged, no drum, no expansion, no water absorption, and good retention and heat insulation performance are reserved.

Description

technical field [0001] The invention relates to the technical field of heat preservation, heat insulation and fire prevention boards, in particular to a vacuum heat insulation board that is 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 infiltration to a ce...

AI Technical Summary

Problems solved by technology

This kind of vacuum insulation panel with single-layer core board and single-layer high-barrier gas-barrier membrane bag structure will inevitably cause problems such as air leakage and bulging once the surface is damaged, thereby losing the effect of heat insulation. 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
