Embodiment Construction

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

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

[0014] The composite method of the double-layer glass fiber cloth casting composite film is: through a film casting machine, a single-layer casting film or a multi-layer co-extrusion casting film is made in the form of single-layer casting or multi-layer co-extrusion casting, and Cast it between the two layers of glass fiber cloth while making the film, forming double-layer PET cast glass fiber cloth, double-layer nylon cast glass fiber cloth, double-layer PVC cast glass fiber cloth, double-layer EVOH cast Glass fiber cloth, double-layer PE cast glass fiber cloth or double-layer PP cast ...

Abstract

Disclosed are a high-barrier composite film for a vacuum heat-insulation plate and a method for manufacturing the high-barrier composite film. The high-barrier composite film is characterized in that two glass fiber cloth layers are compounded on the outermost side of a high-barrier film in a curtain coating manner. The high-barrier composite film and the method for manufacturing the same have the advantages that the two glass fiber cloth layers are compounded on the outermost side of the original high-barrier film of the vacuum heat-insulation plate, by the aid of the excellent affinity and the scratch resistance of glass fiber cloth and cement, the problem that a conventional high-barrier film of a vacuum heat-insulation plate can be scratched and pierced easily, cannot be adhered with cement mortar firmly and is not anti-ageing can be effectively solved, and long-standing, big and difficult problems of an existing vacuum heat-insulation plate 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, 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 problems. 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 vacu...
