摘　　要：本文旨在研究氯化丁基胶在气密层配方中的应用。结果表明,在气密层配方中,使用氯化丁基胶代替溴化丁基胶,老化前后硬度、曲挠、气密性等与原配方基本一致,拉伸强度略有提升,但焦烧时间和正硫化时间T90会延长,提升了焦烧安全性。另外,使用氯化丁基胶可以降低胶料成本。This article aims to explore the application effect of chlorinated butyl rubber in the formulation of airtight layers.The research results show that after using chlorinated butyl rubber instead of brominated butyl rubber in the airtight layer formula,the hardness,flexibility,and airtightness indicators before and after aging remain basically the same as the original formula,while the tensile strength is slightly improved.At the same time,the burning time and sulfurization time(T90)have been extended,thereby improving the safety of burning.In addition,the use of chlorinated butyl rubber can effectively reduce the production cost of rubber compound.
