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, 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.
