Technical Field

Background
Polyimide film is one of the most demanded polyimide products, and its excellent corona resistance, radiation resistance, dielectric properties and dimensional stability make the demand for high-performance polyimide film materials continuously increasing. Due to a large number of imide rings and benzene ring structures in the polyimide main chain, strong intermolecular force exists among molecular chains, so that the polyimide molecular chain structure is compact, the characteristics of difficult dissolution and difficult dissolution are shown, the barrier of mass production and processing of polyimide is formed, and the development of polyimide film products in more application fields is influenced.
In order to avoid the problem of solubility, the production of the polyimide film mainly adopts a two-step method, wherein a polyamic acid solution is synthesized, and then the polyimide film is prepared by a tape-casting film forming process of a pre-drying process and a thermal imidization treatment. Amic acids are generally prepared by reacting a dianhydride with a diamine in an aprotic polar solvent at low temperature by adding the diamine first and then the dianhydride, due to the high solubility of the diamine and the low solubility of the dianhydride, which will hydrolyze with the water in the solvent. However, since the dianhydride and the diamine undergo an exothermic reaction during the polymerization process, the viscosity of the polymerization solution increases, and since the slurry has poor heat insulation and thermal conductivity, the heat at the central part in the kettle is difficult to be transferred to the periphery, and the slurry at the inner periphery of the kettle can rapidly reduce the temperature by heat exchange with the kettle wall, so that the temperature in the kettle is uneven.
