Cracking process of waste butyl rubber

Abstract

The invention belongs to the technical field of cracking of waste butyl rubber, and particularly relates to a cracking process of waste butyl rubber. The cracking box comprises a box body; wherein a driving rod is rotationally connected into the inner wall of the box body through a motor; a circular groove is formed in the inner wall of the driving rod, and first through holes are uniformly formedin the inner wall of the circular groove; the outer surface of the driving rod is fixedly connected with rotating rods which are uniformly arranged, and the two rotating rods correspond to each other; the outer surface of each rotating rod is fixedly connected with a dorsal fin. According to the invention, the method is mainly used for solving the problems that during the pyrolysis process of waste butyl rubber in the prior art, the waste butyl rubber is usually directly put into a lysis solution, which may cause accumulation of the waste butyl rubber in the lysis solution, the cracking liquid can also precipitate and accumulate, so that the problems of partial excessive cracking and partial incomplete cracking of the waste butyl rubber are caused, and meanwhile, excessive cracking of thewaste butyl rubber can generate a large amount of harmful gas, so that the atmosphere and a water source can be polluted are solved.

Description

technical field [0001] The invention belongs to the technical field of cracking waste butyl rubber, in particular to a cracking process of waste butyl rubber. Background technique [0002] Butyl rubber is a kind of synthetic rubber, which is synthesized from isobutylene and a small amount of isoprene. The finished product is not easy to leak, and is generally used to make inner tubes for automobiles and aircraft wheels. Butyl rubber is a copolymer of isobutylene and isoprene, which was put into industrial production in 1943. Butyl rubber, referred to as IIR, is the abbreviation of Isobutylene Isoprene Rubber. It has good chemical stability and thermal stability of butyl rubber, the most prominent is air tightness and water tightness. Its air permeability is only 1 / 7 of that of natural rubber and 1 / 5 of that of styrene-butadiene rubber, while its permeability of steam is 1 / 200 of that of natural rubber and 1 / 140 of that of styrene-butadiene rubber. Therefore, it is mainly...

Problems solved by technology

[0006] In order to make up for the deficiencies in the prior art, the present invention proposes a cracking process for waste butyl rubber. The present invention is mainly used to solve the problem that waste butyl rubber is often placed directly in the cracking solution when cracking waste butyl rubber. However, this approach will lead to the accumulation of waste butyl rubber in the cracking solution, and at the same time, the cracking solution itself will also precipitate and accumulate, so that the waste butyl rubber will be partially cracked and partially cracked. At the same time, the waste Excessive cracking of butyl rubber will produce a large amount of harmful gas, which will cause pollution to both the atmosphere and water sources
