Embodiment Construction

[0012] The invention relates to a high-barrier composite film for vacuum heat insulation panels and a manufacturing method thereof. A layer of glass fiber cloth is compounded by thermal sealing on the outermost side of the high-barrier film of the existing vacuum heat insulation panel cover material.

[0013] The high barrier film is aluminized film, PET film, nylon film, PVC film, EVOH film, PE film or PP film. The specific heat-sealing method is: melt all or part of the aluminized film, PET film, nylon film, PVC film, EVOH film, PE film or PP film on one side of the glass fiber cloth by adding it on the film heat-sealing machine , and through cooling, flattening and pressing together, it becomes aluminized glass fiber cloth, PET glass fiber cloth, nylon glass fiber cloth, PVC glass fiber cloth, EVOH glass fiber cloth, PE glass fiber cloth or PP glass fiber cloth, collectively referred to as Fiberglass cloth composite membrane.

[0014] The specification of described glass f...

Abstract

Disclosed are a high-barrier composite membrane for a vacuum insulated panel and a method for manufacturing the high-barrier composite membrane. The high-barrier composite membrane is characterized in that a glass fiber cloth layer is composited on the outermost side of an original high-barrier membrane for the vacuum insulated panel in a heat-sealing mode. The high-barrier composite membrane has the advantages that by the aid of excellent affinity and scratch resistance of glass fiber cloth and cement, the problem that a high-barrier membrane for a conventional vacuum insulated panel is subject to scratch and puncture, is not firmly adhered with cement mortar and is not anti-aging can be effectively solved, and long-standing, big and difficult problems of an existing vacuum insulated panel for building are solved.

Description

technical field [0001] The invention relates to a cover material for a vacuum-pumped thermal insulation board, in particular to a high-barrier composite film and a manufacturing method thereof. Background technique [0002] Existing high-barrier films for vacuum insulation panels are mainly made of aluminum foil, PET film, nylon film or PP film. Alkali etc. Once it is pierced during construction, it will not only greatly reduce the thermal insulation performance, but also destroy the structure of the entire thermal insulation layer. Contents of the invention [0003] The present invention aims to provide a high-barrier composite film for vacuum insulation panels and its manufacturing method, so as to solve a series of problems such as bonding, aging, scratching, and puncture of existing vacuum insulation panels used in buildings. [0004] The technical solution of the present invention is: a high-barrier composite film for vacuum insulation panels, characterized in that ...
