Reaction device of high-permeability PBT (polybutylene terephthalate) copolyester waterproof moisture-permeable film

The utility model discloses a reaction device of a high-permeability PBT (polybutylene terephthalate) copolyester waterproof moisture-permeable film, and relates to the technical field of PBT copolyester processing. The reaction device of the high-permeability PBT copolyester waterproof moisture-permeable film comprises a reaction kettle body, a rotating rod is arranged in the reaction kettle body, and a rotating feeding mechanism is arranged above the rotating rod. According to the reaction device for the high-permeability PBT copolyester waterproof moisture-permeable film, the wire roller, the rotating bevel gear, the driven bevel gear, the large gear and the small gear are arranged and matched; when a rotating rod drives a stirring plate to stir a copolyester solution, a catalyst can be continuously and uniformly scattered on the surface of the copolyester solution through centrifugal force generated by the rotary feeding mechanism during rotation, so that the copolyester solution is more quickly and unifo
