Embodiment

[0036] refer to figure 2 , a breathable anchored vacuum insulation panel described in this embodiment includes: a core material 10, a core material punching area 20, a vacuum packaging barrier film 30, an annular heat sealing area 60 in the panel, and a circular mechanical punching area in the panel 70 . Barrier film heat sealing area 80 , rectangular hole 90 .

[0037] When the vacuum insulation panel is prepared, the specific process steps are as follows:

[0038] (1) heat-seal the three sides of the vacuum packaging barrier film, and leave a hole on the fourth side for filling the core material and vacuuming;

[0039] (2) Mechanical punching at the heat-sealed edge, the rectangular hole is 8mm long and 3mm wide, and the hole interval is 80mm and evenly distributed to form a vacuum-encapsulated barrier film with rectangular holes on the side heat-sealed edge.

[0040] (3) The core material is perforated by a circular hole puncher, and the hole is located in the center of ...

Abstract

The invention discloses an air-permeable anchored vacuum heat-insulation plate and a manufacturing method thereof. The vacuum heat-insulation plate comprises a core material, a core material perforating area, a vacuum packaging separation film, a mechanical punching hot seal area in the middle of the plate and a mechanical punching area at a hot-sealed edge. Holes are perforated on the hot-sealed edge of the vacuum heat-insulation plate and in the middle of the plate, the middle hole is used for anchoring, and air permeates through the hole of the hot-sealed edge. The vacuum heat-insulation plate for buildings simultaneously has the advantages of air permeability and capabilities of being anchored and leading a through-wall facility to pass through the vacuum heat-insulation plate smoothly due to the perforated holes, a comprehensive application effect of the vacuum heat-insulation plate after the vacuum heat-insulation plate is arranged on a wall by the aid of construction is optimized, and the service range of the vacuum heat-insulation plate is further expanded.

Description

technical field [0001] The invention belongs to the technical field of heat insulation material engineering, and in particular relates to a breathable and anchored vacuum heat insulation panel and a preparation method thereof. Background technique [0002] The vacuum insulation panel is made of glass fiber as the core material, and the gas-barrier composite film as the packaging bag, which is prepared after vacuum packaging. Because it maximizes the vacuum inside the panel and reduces gas convection to achieve high-efficiency thermal insulation, it has extremely low thermal conductivity and excellent thermal insulation performance. It is currently the most advanced high-efficiency thermal insulation material in the world. [0003] With the advancement of technology, more and more attention has been paid to its application in the thermal insulation of building exterior walls. As a thermal insulation material for building exterior walls, vacuum insulation panels have the adva...
