Abstract

The invention discloses a production device and method of a thermoplastic polyimide film. The device comprises a reaction kettle, a defoaming box and a casting box, connecting pipes are jointly welded and fixed to the reaction kettle and the defoaming box and the defoaming box and the casting box in a penetrating manner, and a liquid inlet pipe is welded and fixed to the position, away from the defoaming box, of the reaction kettle in a penetrating manner. Two feeding pipes are symmetrically welded and fixed to the top wall of the reaction kettle in a penetrating manner, feeding hoppers are welded and fixed to the top walls of the two feeding pipes in a penetrating manner, a grinding sleeve and a flow guide sleeve are welded and fixed to the inner wall of the reaction kettle, a grinding device is arranged in a motor sleeve, and a knocking and vibrating device is arranged in the reaction kettle. A proportion adjusting device is arranged in the feeding pipes. The device has the advantages that by arranging the structures such as a grinding plate and the grinding sleeve, blocky particles are ground and crushed by rotating the grinding plate, so that raw materials can be fully mixed with liquid, and the raw materials are more fully and uniformly stirred.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a production device and a production method of a thermoplastic polyimide film. Background technique [0002] Thinness, lightness and miniaturization have become the trend of technological development of electronic products, especially portable electronic products, and flexible printed circuit boards have become a "favorite" among the various types used in electronic products. Copper-clad laminate (FCC) is composed of copper foil (acting as a conductor), film (acting as an insulating substrate), and adhesive (as a bonding material between film and copper foil). Due to the expansion of FPC technology and application fields, the The mechanical strength and rigidity of the film substrate have higher requirements. Under this market demand, polyimide film material products have been developed to serve as insulating substrates. [0003] However, polyimide thin film materials ...
