HIGH-BARRIER COMPOSITE FILM FOR VACUUM THERMAL INSULATION PANEL AND MANUFACTURING METHOD THEREFOR

摘要

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.
