Problems solved by technology

However, since both sides of the vacuum insulation panel are high-density gas- and water-blocking films, after the wall is installed, the water vapor between the vacuum insulation panel and the wall cannot be discharged. Cause mildew between the building wall and the insulation board, seriously affecting the indoor environment

Embodiment

[0028] refer to image 3 , an edge-sealing oval opening vacuum insulation panel described in this embodiment includes: a core material 10 ; a barrier film 20 ; an oval opening 30 . The major semi-axis of the ellipse is 4mm, and the minor semi-axis is 1.5mm.

[0029] When the vacuum insulation panel is prepared, the specific process steps are as follows:

[0030] (1) In the production process of the vacuum insulation panel packaging bag, the three sides of the barrier film are sealed, and one side is used as a vacuuming port;

[0031] (2) Mechanical punching of elliptical holes is carried out in the middle of the heat-sealing edges on both sides of the barrier film, and the hole and the edge of the hole are separated by 80mm to form a vacuum insulation panel packaging bag with elliptical holes on the side heat-sealing edges;

[0032] (3) The core material is placed in a packaging bag, and the whole is put into a vacuum heat sealing machine to be evacuated, and the opening edg...

Abstract

The invention discloses an edge-sealed and opened building heat-insulating vacuum insulated panel and a manufacturing method thereof. The edge-sealed and opened building heat-insulating vacuum insulated panel comprises a core and a barrier film, wherein equidistant round holes, elliptical holes and rectangular holes are formed in two sides or a plurality of heat sealing edges of the edge-sealed and opened building heat-insulating vacuum insulated panel. When the edge-sealed and opened building heat-insulating vacuum insulated panel disclosed by the invention is applied to the building, the heat sealing edges of the insulated panel are mutually stacked and ventilation holes are vertically aligned and completely exposed, so that water vapor of a cement mortar layer between a wall body and the vacuum insulated panel can be smoothly evaporated and the phenomena that the inside of the wall body is mildewed and the like are avoided.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation material engineering, and in particular relates to a building thermal insulation vacuum thermal insulation panel with edge sealing and opening holes and a preparation method thereof. and rectangular holes. Background technique [0002] The vacuum insulation panel is composed of filling core material and vacuum protective surface layer. It effectively avoids heat transfer caused by air convection, so it has extremely low thermal conductivity, excellent thermal insulation performance and good environmental protection performance. It is currently the most advanced in the world. high-efficiency thermal insulation material. Vacuum insulation panel is a thermal insulation and environmental protection material with excellent thermal insulation performance, and there is no pollution in the process of manufacturing, use and post-use treatment. [0003] With the advancement of technology, its r...
