Embodiment Construction

[0012] The invention relates to a high-barrier composite film for vacuum insulation panels and a manufacturing method thereof. A layer of glass fiber cloth is compounded with an adhesive on the outermost side of the barrier composite film.

[0013] The binder is solvent-based or water-based glue (such as 3166 solvent-based glue from Beijing Gaomeng Company, 7132 water-based glue from Shanghai Bayer); the high-barrier film is aluminum foil, aluminized film, PET film, nylon film, PVC film, EVOH film, PE film or PP film, the specific composite method is: apply the adhesive on the outside of the high barrier film with a rubber roller, and dry the excess in the adhesive by electric heating or hot air drying. After the solvent or water is drained, the above-mentioned high barrier film and glass fiber cloth are combined by heating and extrusion to form aluminum foil glass fiber cloth, aluminized glass fiber cloth, PET glass fiber cloth, nylon glass fiber cloth, PVC glass fiber cloth,...

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 an adhesive agent is a layer of glass fiber cloth. 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 composite 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, characterized in that ...
