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 cast composite film is compounded on the outside of the existing vacuum heat insulation panel cover material. The glass fiber cloth cast composite film is produced in The outer side of the high barrier film is compounded with a layer of glass fiber cloth by casting.

[0013] The high barrier film is PET film, nylon film, PVC film, EVOH film, PE film or PP film.

[0014] The glass fiber cloth casting composite film is made of PET film, nylon film, PVC film, EVOH film, PE film or PP film, and is compounded with glass fiber cloth in the form of single-layer casting or multi-layer co-extrusion casting through the casting machine. Together. The specific composite method is: through a film casting machine, a single-layer cast film or a multi-layer co-extrusion cast film is made in the form of a single-layer cast film or a ...

Abstract

A high-barrier composite film for a vacuum thermal insulation panel and manufacturing method therefor. Both internal and external sides of the high-barrier film is attached with two layers of glass fiber cloth by means of heat sealing, thereby forming a glass fiber cloth composite film. Two layers of glass fiber cloth are attached to the outer-most sides of the existing high-barrier film of the vacuum thermal insulation panel; the glass fiber cloth is scratch resistant and has good affinity with cement, thereby effectively solving the problem of high-barrier films of regular vacuum thermal insulation panels being vulnerable to scratching, stabbing, and aging, and having bad bonding with cement and mortar.

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, PE film or PP film. The disadvantages are that they are afraid of scratches and punctures, and they are not firmly bonded to cement mortar and are not anti-aging. , Not alkali resistance and other issues. 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...
