Abstract
The utility model discloses a reaction kettle for polymerizing butadiene styrene rubber which can overcome the defect in the prior art and has a high reaction speed and a high conversion rate. The reaction kettle for polymerizing butadiene styrene rubber comprises a kettle body, wherein a plurality of inner cooling tube nests and a stirrer are arranged inside the kettle body; the stirrer is installed on a stirring shaft; an ammonia gas outlet is formed at the top end of the kettle body; a liquid ammonia inlet is formed at the bottom end of the kettle body; and the reaction kettle for polymerizing butadiene styrene rubber is characterized in that 9 groups of inner cooling tube nests are provided and are arrayed in a combination way that each group has 24 tube nests. The volume of the kettle body is changed by regulating the diameter and the length of the kettle body, so that the highest reaction speed and conversion rate can be achieved.
Description
Technical field
The present invention relates to a kind of production technique device of styrene-butadiene rubber(SBR), especially a kind of styrene-butadiene rubber(SBR) polymerization reaction kettle.
Background technology
Styrene-butadiene rubber(SBR) is to be monomer with divinyl and vinylbenzene, is that output is the highest in the world at present, the general purpose synthetic rubber kind that consumption is maximum.Its adopt letex polymerization that radical causes or anionic solution polymerization technology and, employing emulsion polymerizations how industry in.
In the polyreaction of styrene-butadiene rubber(SBR), at first, in pipeline, mix again with the divinyl of handling well with relative molecular mass regulator uncle ten alkyl sulfhydryls and vinylbenzene mixed dissolution in pipeline of volume pump with specified quantity.In pipeline, mix the back with emulsifier mix liquid (emulsifying agent, deionized water, reductor etc.) etc. then and get into water cooler, be cooled to 10 ℃.Mix with activator solution (reductive agent, sequestrant etc.) again, react from the bottom entering paradigmatic system of styrene-butadiene rubber(SBR) polymerization reaction kettle.
The effect of styrene-butadiene rubber(SBR) polymerization reaction kettle is that reactant is reacted equably, and homogeneous and controllable ground derivation heat, and therefore, the size of reaction kettle, heat transfer type and whipped form are the key characters of reaction kettle.Reaction kettle of the prior art send out little not wait from 15 cubic metres to 45 cubic metres, the heat exchange form has chuck form and tubulation form, whipped form has oar formula and Pu Lumanjin (BRUMANGIN) formula etc.Speed of response is slow, transformation efficiency is low and the shortcoming of poor product quality yet styrene-butadiene rubber(SBR) polymerization reaction kettle of the prior art, ubiquity.
Summary of the invention
The technical problem that the present invention will solve provides and a kind ofly can overcome the prior art defective, the styrene-butadiene rubber(SBR) polymerization reaction kettle that speed of response is fast and transformation efficiency is high.
For addressing the above problem, a kind of styrene-butadiene rubber(SBR) polymerization reaction kettle of the present invention comprises kettle; Be provided with in the kettle several in cold tubulation and whisking appliance; Whisking appliance is installed on the stir shaft, and the kettle top is provided with ammonia outlet, and the bottom is provided with the liquefied ammonia inlet; It is characterized in that: cold tubulation is divided into 9 groups in said, and carries out array with 24 every group array mode.
Said whisking appliance is the Pu Lumanjinshi whisking appliance, totally three layers, and every layer of three blade.
Said kettle diameter is 3000mm, and long 5300mm is arranged with elipse head on the kettle.
Adopt the styrene-butadiene rubber(SBR) polymerization reaction kettle of structure of the present invention,, thereby change the kettle volume, can make it reach the fastest speed of response and transformation efficiency through the diameter and the length of adjustment kettle.Adopt the Pu Lumanjinshi whisking appliance, totally three layers, every layer of three blade, can make in the reaction kettle mixed solution fully, evenly react.In cold tubulation structure, play the effect that heat is derived on homogeneous and controllable ground.
Description of drawings
Fig. 1 is the structural representation of styrene-butadiene rubber(SBR) polymerization reaction kettle among the present invention.
Embodiment
In order to make those skilled in the art person understand technical scheme of the present invention better, the present invention is done further detailed description below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1, styrene-butadiene rubber(SBR) polymerization reaction kettle of the present invention comprises kettle 1, be provided with in the kettle 1 several in cold tubulation 2 and whisking appliance 3, whisking appliance 3 is installed on the stir shaft 4.
Kettle 1 top is provided with ammonia outlet 5, and the bottom is provided with liquefied ammonia inlet 6, said in cold tubulation 2 be divided into 9 groups, and carry out array with 24 every group array mode.
Said whisking appliance 3 is the Pu Lumanjinshi whisking appliance, totally three layers, and every layer of three blade.
Said kettle 1 diameter is 3000mm, and long 5300mm is arranged with elipse head on the kettle 1.
Adopt the styrene-butadiene rubber(SBR) polymerization reaction kettle of structure of the present invention,, thereby change the kettle volume, can make it reach the fastest speed of response and transformation efficiency through the diameter and the length of adjustment kettle 1.
In cold tubulation 2 be divided into 9 groups, and carry out array with 24 every group array mode, play the effect that heat is derived on homogeneous and controllable ground.
