Flexible environment-friendly high-temperature-resistant protective film and preparation method thereof

Abstract

The invention relates to the technical field of film manufacturing, in particular to a flexible environment-friendly high-temperature-resistant protective film and a preparation method thereof. The protective film includes a basic core layer and an infrared reflective layer and is prepared from following raw materials: aromatic polyamide fiber, nano copper oxide, nano zinc sulfide, perfluoroalkylpolyether, phenolic resin modified chloroprene rubber adhesive, polytetrafluoroethylene, polybenzimidazole fiber, basalt fiber, nano silicon dioxide, epichlorohydrin rubber, o-cresol formaldehyde epoxy resin, methyl silicone rubber, polyurethane modified epoxy resin and sulfur trioxide. The film disclosed by the invention is subjected to multi-layer treatment, so that the whole film is clear in hierarchy and the heat conduction effect can be reduced; the heat absorption of the whole film can be reduced through multi-layer reflection of external radiation, and the film has better high-temperature tolerance and heat insulation effect, good manufacturing link and environmental compatibility and better environmental suitability.

Description

technical field [0001] The invention relates to the technical field of film manufacturing, in particular to a flexible, environment-friendly and high-temperature-resistant protective film and a preparation method thereof. Background technique [0002] Films made of organic polymers. With the development of the petroleum industry and technology, the application field of polymer film has been continuously expanded, from the initial packaging film to intelligent polymer film, polymer functional film and so on. With its excellent performance, polymer membranes are used in nuclear fuel and metal extraction, gas separation, seawater desalination, ultrapure water preparation, sewage treatment, artificial organ manufacturing, medicine, food, agriculture, chemical industry and other fields. However, there are few researches on polymer membranes in the current technology under high heat use, and the production of polymer membranes is mostly simple mixing and coagulation, which makes ...

Problems solved by technology

However, there are few researches on polymer membranes in the current technology under high heat use, and the production of polymer membranes is mostly simple mixing and coagulation, which makes it difficult to exert the excellent performance of polymer membranes

For example, the patent number is CN201310658538.7, a heat-insulating plastic film and its production method. It consists of an acid-doped polymethacrylate film and a nano-tin dioxide crystalline heat-insulating layer deposited on the surface of the film, so that the film can be attached to the glass surface. The heat insulation effect is good, the plastic film is soft in texture and high in strength, but its high temperature resistance effect range is narrow, and the high strength of the film cannot be exerted in special environments; another example is the patent number CN201510600862.2, which is a high temperature resistant isolation film and its preparation method, the use of coated silicon rubber on the base material makes it have good wettability and physical entanglement with the non-woven fabric fibers. After the crosslinking agent is cured, the overall strength is high and the flexibility is very good, but the heat insulation of the film The method is simple, only by using high temperature resistant materials, the use effect under continuous high temperature is poor
