Embodiment Construction

[0012] The present invention relates to a high-barrier composite film for vacuum insulation panels and a manufacturing method thereof. A two-layer glass fiber cloth composite film is thermally synthesized by a heat-sealing machine on both sides of the high-barrier film of an existing vacuum insulation panel cover material, which is called a double-layer glass fiber cloth composite film. Layer glass fiber cloth composite membrane.

[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 the two-layer glass fiber cloth on the film heat-sealing machine. After cooling, flattening and pressing together, it becomes double-layer aluminized glass fiber cloth, double-layer PET glass fiber cloth, double-layer nylon glass fiber cloth, double-layer PVC glass fiber cloth, double-layer EVOH gla...

Abstract

A high-barrier composite film for a vacuum thermal insulation panel and manufacturing method therefor, characterized in that attached to the outer-most side of the high-barrier film by means of casting is a layer of glass fiber cloth, thereby forming a glass fiber cloth casting composite film. The advantages of the present invention are that: a layer of glass fiber cloth is attached to the outer-most side 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, and solving the long-standing difficulties of vacuum thermal insulation panels in construction.

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, which is characterized...
