Abstract

The invention relates to a liquid spray electrotherapy room treated by coating carbon fibers and a coating system thereof. The coating system is composed of a de-coiling device, a guiding device, a flattening device, a liquid spray electrotherapy room, an electrostatic coating room, a melting furnace, an adjusting device, an electrostatic device, a resin content test system, a traction device, a coiling device, a powder device, a control system and a compressed air source. A presoaked fabric passes by the liquid spray electrotherapy room with liquid spray electricity and then passes by the coating room with the electrostatic resin powder, so that the two sides of the presoaked fabric are coated with the resin powder; the fabric is flattened by the melting furnace under high temperature, and then the resin is adhered to the presoaked fabric; in order to uniformly and flatly soak, an X-ray instrument and a computer are adopted for detecting and controlling in the whole soaking process, so as to guarantee the controllable increasing of the soaked resin content of the fabric and meet the requirement of the manufacturing for 1000mm wide high-quality pre-coated fabric. The device is suitable for solvent-free thermosetting resin and thermoplastic resin.

Description

technical field [0001] The invention relates to the field of carbon fiber coating treatment. Background technique [0002] In recent years, research on a series of prepreg equipment and process methods has been carried out around the preparation of thermoplastic resin prepregs, including melt impregnation, solution impregnation, fiber impregnation, powder impregnation, suspension impregnation, electrostatic impregnation, etc., which exist to varying degrees. There is a lack of suitable solvents, the resin is heated for a long time, it is difficult to remove water and emulsifiers, and the surface of the impregnated layer is uneven and smooth. The fluidized bed impregnation process disclosed in Dutch patent IIM861464 adopts Fen powder impregnation, which utilizes the deposition and adhesion of resin powder on prepreg fibers to obtain prepregs. However, it also has the disadvantages of uneven adhesion of resin powder and limited precision of prepreg resin content. Contents o...
