Abstract

The invention belongs to the technical field of chemical reactors and discloses a butyl rubber polymerization reactor. The butyl rubber polymerization reactor comprises a rack, wherein a cavity and astirring shaft are arranged on the rack; the stirring shaft penetrates through two ends of the cavity; in addition, a communicating pipe which is spirally arranged is arranged on the outer wall of thestirring shaft; the butyl rubber polymerization reactor further comprises a piston barrel; a piston is in sliding connection with the inner part of the piston barrel; the butyl rubber polymerizationreactor also comprises a first support rod, a second support rod and a third support rod which are sequentially hinged; a first air inlet and a first air outlet ate formed in one closed end of the piston barrel; a first air inlet one-way valve is arranged in the first air inlet; a second air outlet one-way valve is arranged in the first air outlet; a negative pressure pipe is communicated betweenthe first air inlet and the communicating pipe; in addition, a feeding opening is formed in the bottom end of the communicating pipe; a discharging opening is formed in the upper end of the communicating pipe; a discharging one-way valve is arranged on the discharging opening; a gas guide pipe is communicated between the stirring shaft and the first air outlet. According to the butyl rubber polymerization reactor disclosed by the invention, the problem that formed butyl rubber has poor quality because uniform mixing cannot be realized in the processing process of the butyl rubber in the priorart is solved.

Description

technical field [0001] The invention belongs to the field of chemical reactors, in particular to a butyl rubber polymerization reactor. Background technique [0002] Butyl rubber is a kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. It is generally used in the production of car tires and car sound insulation products. Because of its good airtightness and watertightness, it is often used in the field of automobile or building waterproofing. The production of butyl rubber mainly includes slurry method and solution method. Slurry method: The slurry method is prepared by cationic polymerization of isobutylene and a small amount of isoprene at low temperature (about -100°C) with methyl chloride as the diluent and H2O-AlCl3 as the initiation system. Solution method: refers to the use of polymerization ax to carry out polymerization reaction to form butyl rubber. [0003] In the polymerization reaction of butyl rubber, in order to ...
