Problems solved by technology

[0002] At present, few domestic manufacturers can produce high-barrier fireproof products. Some foreign companies purchase and sell to China and other countries in Malaysia and other countries. Many domestic companies can only produce two-layer products of aluminum foil and glass fiber cloth. The overall material It is thin and has poor ductility, which cannot meet the new requirements of the current market for packaging.
[0003] Foreign companies use high-barrier, fire-proof and high-temperature-resistant materials as their core technology to protect, and it is difficult to obtain technical cores such as production technical parameters, while domestic manufacturers have not yet developed similar products and production processes that can compete with them

Abstract

The invention discloses a high-barrier, fireproof and high temperature resistant composite material and a preparation method thereof. The high temperature resistant composite material comprises a polyester layer, a polyvinyl chloride soft cloth layer, an adhesive sticker layer and a paper centrifugal film layer which are composited sequentially. The preparation method of the composite material comprises steps as follows: patterns are printed on a polyester film in a preset mode; a dry compound machine is used for gluing, the polyester film and polyvinyl chloride soft cloth are heat-sealed and rolled at certain temperature and pressure, and an intermediate product is obtained; the rolled intermediate product is cured at a certain temperature; after a rolled film is cooled, the dry compound machine is used for gluing, and the film is composited and rolled with a paper centrifugal film at certain pressure; and slitting and packaging are performed according to preset specifications. The composite material has excellent ductility and softness, breaks the technological monopoly of foreign companies, fills the technological blank and the product blank at home and has a wide market prospect; and the production process is green, environment-friendly and energy-saving, meets requirements of the national high technology industry and has outstanding technological advantages.
