Abstract
The utility model relates to a reactor for preparing chlorinated polypropylene, and provides a reactor for chlorinated polypropylene photo-initiation, which comprises an airtight reactor, ultraviolet light source, a chlorine gas distributor and a stirring apparatus. The ultraviolet light source is arranged in the reactor. The chlorine gas distributor is arranged at the bottom of the reactor, and is communicated with a chlorine gas inlet through a pipe. The stirring apparatus comprises a hollow stirring shaft and a self-sucking type stirring paddle. The lower end of the stirring shaft is extended to the bottom of the reactor. The self-sucking stirring paddle is fixed on the stirring shaft, and is arranged below the middle of the stirring shaft. An opening is arranged at the upper end of the stirring shaft. The self-sucking stirring paddle comprises a hollow shell of which both ends are open. One end of the shell is fixedly connected with the stirring shaft. A cavity of the shell is communicated with a cavity of the stirring shaft. The other end of the shell is stretched out. With simple structure, the reactor for chlorinated polypropylene photo-initiation is easy to industrial facility, thereby obviously reducing chlorine gas consumption and avoiding risk during operating.
Description
Technical field
The utility model relates to the reactor for preparing Chlorinated Polypropylene III, relates in particular to the whipping appts of reactor.
Background technology
Chlorinated Polypropylene III (being called for short CPP, down together) can be divided into two classes:
High Chlorinated Polypropylene III: chlorination degree is 63～67%; Purposes: the surrogate of chlorinated rubber, the tackiness agent of printing ink and paint, and the additive of inflammable substance.
Low Chlorinated Polypropylene III: chlorination degree is in 20～40% (comprising Hardlen); Purposes: be mainly used in tamanori, at first be used for the thermosealed precoated layer of polypropylene film; The printing-ink of polypropylene product and the vehicle of paint.
Polyolefinic chlorination has had extensive studies, but since polyacrylic poorly soluble, so the report of relevant Chlorinated Polypropylene III is seldom.The isotatic polypropylene dissolving needs quite high temperature.This just makes the homogeneous phase chlorination very difficult.
CPP is made through chlorination reaction by polypropylene, and at present, production method mainly contains chloride solution (is solvent with the tetracol phenixin), aqueous suspension chlorination method and chlorination by solid state method.
The light-initiated Chlorinated Polypropylene III for preparing of Chlorinated Polypropylene III is a kind of comparatively advanced method, and this method feeds reactor with excessive chlorine, reacts with polypropylene.In reaction process, unreacted chlorine accumulates in the top of liquid level in the reactor, and not only also there is certain danger simultaneously in the consumption of the chlorine of Zeng Jiaing.
Summary of the invention
The purpose of this utility model provides a kind of light-initiated reactor of Chlorinated Polypropylene III that is used for, to overcome the above-mentioned defective that prior art exists.
The light-initiated reactor of Chlorinated Polypropylene III that is used for of the present invention comprises airtight reactor, ultraviolet source, chlorine gas distributor and whipping appts;
Described ultraviolet source is arranged in the described reactor, described chlorine gas distributor is arranged on the bottom of reactor, and be connected with the chlorine inlet that is arranged on reactor head by pipeline, described whipping appts comprises the stir shaft and the self-priming stirring rake of hollow;
The lower ends downward of described stir shaft extends to the bottom of reactor, and described self-priming stirring rake is fixed on the stir shaft, and is positioned at below the middle part of stir shaft, and the upper end of described stir shaft is provided with opening;
Described self-priming stirring rake comprise both ends open, hollow housing, an end of housing is fixedlyed connected with described stir shaft, and the cavity of housing is connected with the cavity of stir shaft, the other end of housing outwards stretches.
The utility model in use, in reactor, after chlorine had been assembled in the top of material, the rotation oar of stir shaft drove hollow housing and rotates together, because action of centrifugal force, the intravital gas of shell is thrown out of, cause the cavity of housing and the cavity of stir shaft to produce negative pressure, thereby accumulate in the chlorine of the top of material, be inhaled into the stir shaft of hollow, further, enter in the reaction mass by the end of housing.
The utility model, simple in structure, be easy to the industrialization facility, can obviously reduce the consumption of chlorine, the danger that exists when avoiding operating.
