Abstract

The invention relates to a high-flame-retardance resin thin film and a preparing method thereof. The thin film is a reaction production of aromatic quaternary amine, tetrabromophthalic anhydride, aromatic binary amine and aromatic binary anhydride. The thin film has quite high flame retardance, heat resistance, electrical insulativity, excellent mechanical performance and the like; the preparing method of the thin film is high in universality, mild in reaction condition, simple in operation, low in cost, friendly to the environment and beneficial for industrial large-scale production and can be applied to the high-tech fields of large motor main insulation materials, electromagnetic wire covering electrical insulation materials, flexible copper-clad plates (FCCL) and the like.

Description

technical field [0001] The invention belongs to the field of organic films, in particular to a high flame-retardant resin film and a preparation method thereof. Background technique [0002] In the field of organic polymers, polyester, polycarbonate, polyurethane, polyacrylate, polyacrylonitrile, polyethylene, polypropylene, polystyrene, etc. can produce resin film materials with wide application value, but their heat resistance Both resistance and flame retardancy have defects. [0003] Polyimide film is a kind of polymer material with excellent comprehensive properties. It has particularly excellent heat resistance, low temperature resistance, electrical properties and mechanical properties. It is widely used in electronic microelectronics, printed circuit boards, wires, etc. Cables, motor main insulation, shipping, aerospace, laser, photoelectric and other high-tech fields. [0004] Traditional polyimide films, such as the KAPTON film produced by the American DUPONT com...
