Description

Technical Field

[0001] The utility model relates to the technical field of butadiene rubber processing, in particular to a novel temperature-controllable stirring polymerization reaction kettle for butadiene rubber. Background Art

[0002] Butadiene rubber is a synthetic rubber, usually composed of a copolymer of styrene and butadiene. Butadiene rubber is usually cheaper than natural rubber, shows good performance in many applications, and maintains elasticity at all temperatures. When processing butadiene rubber, when mixing butadiene rubber with other materials, simply stirring it will easily cause the other materials to not mix into the butadiene rubber, resulting in insufficient mixing of butadiene rubber and other materials.

[0003] The Chinese patent discloses a polybutadiene rubber polymerization reactor (authorization announcement number CN214598981U), which comprises a reactor body, a feed inlet, a stirring device, and a discharge port; wherein the reactor body is provided with a temperature-controlled jacket, a feed inlet is arranged on the upper part of the reactor body, a hole is opened on the top of the reactor body for arranging the stirring device; a discharge port is arranged at the bottom of the reactor body; the stirring device comprises a motor, a motor bracket, a reducer, a stirring shaft, and a stirring blade; the motor is arranged on the motor bracket and connected to the stirring shaft through a reducer; wherein the stirring blade is a two-stage structure, a spiral ribbon blade is arranged on the upper main part of the stirring shaft, the spiral ribbon blade is divided into an outer spiral ribbon and an inner spiral ribbon, the outer spiral ribbon is fixed to the stirring shaft through a spiral ribbon support arm, the inner spiral ribbon is fixed to the stirring shaft, the spiral directions of the outer spiral ribbon and the inner spiral ribbon are opposite, and an anchor stirring blade is arranged at the lower part of the stirring shaft.

[0004] However, there are still some shortcomings in this patent. This patent improves the stirring device, especially the blades, and selects stirring blades according to the characteristics of different layers in the stirring kettle to prevent the polymer from accumulating into blocks on the stirring shaft, improve the stirring efficiency, and ensure the quality of the polymer product; however, when the butadiene rubber is mixed with other materials, it is easy to cause other materials to not be mixed into the butadiene rubber by simply stirring, so that the butadiene rubber and other materials are not stirred and mixed sufficiently. Therefore, those skilled in the art provide a new type of butadiene rubber temperature-controlled stirring polymerization reactor to solve the problems raised in the above background technology.
