摘要
研究改性裂解炭黑在全钢载重子午线轮胎内衬层胶中的应用。结果表明:在内衬层胶中采用改性裂解炭黑等量替代部分炭黑N660,胶料的门尼焦烧时间和硫化特性相近;硫化胶的定伸应力、拉伸强度和撕裂强度增大,耐屈挠疲劳性能和气密性能相当;成品轮胎的高速和耐久性能符合企业标准要求,同时可降低胶料成本。
The application of modified pyrolytic carbon black in the inner liner compound of truck andbus radial tire was investigated. The results showed that,by using modified pyrolytic carbon black to replace part of carbon black N660 by equal weight in the inner liner compound,the Mooney scorch time and curing characteristics of the compound were kept unchanged. The modulus,tensile strength and tear strength of the vulcanizate increased,and the flexural fatigue resistance and air tightness were comparable. The high speed performance and endurance of the finished tire met the requirements of the enterprise standard,and the compound cost was reduced.
