Description
Technical Field

Background
Butyl rubber is one of the synthetic rubbers, synthesized from isobutylene and a small amount of isoprene. The product is not easy to leak, and is generally used for manufacturing inner tubes of wheels of automobiles and airplanes. Butyl rubber is a copolymer of isobutylene and isoprene, which was commercially produced in 1943. Butyl Rubber, abbreviated IIR, is an abbreviation for Isobutylene Isoprene Rubber. Has good chemical stability and thermal stability of butyl rubber, and most prominently has air tightness and water tightness. Its permeability to air is only 1/7 for natural rubber and 1/5 for styrene-butadiene rubber, while its permeability to steam is 1/200 for natural rubber and 1/140 for styrene-butadiene rubber. Therefore, the method is mainly used for manufacturing various rubber products such as various inner tubes, steam tubes, water tires, dam bottoms, gaskets and the like, and at present, the cracking of the waste butyl rubber mainly adopts a dynamic method, an internal mixer method and a rubber frying method. The problems of difficult glue production, waste gas emission and the like exist after the cracking by a dynamic method; the internal mixer method has the problems of high energy consumption and incapability of centralized treatment of waste gas; although the rubber frying method has low energy consumption, the waste gas pollution is very serious, the product quality is very unstable, the rubber loss is large when the rubber is cracked by adopting the methods, and the introduction of the waste butyl rubber can be seen in the journal period: zhongjiang, Zhang Zhong, Zhou Asia, Wang Liang Sheng, Xiahan bridge, waste butyl rubber regeneration and application, regeneration resources and recycling economy 2008(03), however, certain problems still exist in the cracking of the waste butyl rubber at present, and the problems specifically comprise the following aspects:
waste butyl rubber often directly puts waste butyl rubber in the lysate among the prior art when the schizolysis, however this kind of way can lead to waste butyl rubber can produce in the lysate and pile up, and lysate itself also can take place to deposit and pile up simultaneously to make waste butyl rubber cause partial excessive schizolysis, the problem of partial incomplete schizolysis, the excessive schizolysis of waste butyl rubber can produce a large amount of harmful gas simultaneously, thereby can all cause the problem of pollution to atmosphere and water source.
There are some proposals for cracking waste butyl rubber, such as patent No. 201210303126.7 entitled waste butyl rubber cracking process, which is to press part of water and gas into another cracking tank to be reacted to crack waste butyl rubber, however, the cracking method can lead to excessive cracking of waste butyl rubber, and a large amount of toxic gas is generated due to excessive cracking of waste butyl rubber.
