摘　　要：研究纳米粘土在半钢子午线轮胎胎侧胶中的应用。结果表明:以一定量的纳米粘土替代炭黑N660,胶料的加工性能和硫化特性变化不大,硫化胶的拉断伸长率和撕裂强度明显增大;随着纳米粘土用量的增大,硫化胶的密度增大,定伸应力减小,耐屈挠疲劳性能提高;以纳米粘土等量替代炭黑N660,填料分散性稍好,成品轮胎的高速和耐久性能达到企业标准要求,胶料成本下降。The application of nano-clay in the sidewall compound of steel-belted radial tires was studied.The results showed that by using a certain amount of nano-clay to replace the same amount of carbon black N660,the elongation at break and tear strength of the vulcanizate increased significantly,while the processability and vulcanization characteristics of the compound changed little.As the dosage of nano-clay increased,the density of the vulcanizate increased,the modulus decreased,and the flexural fatigue resistance was improved.In addition,the filler dispersion was slightly improved,the high speed performance and durability of the finished tire met the requirements of the enterprise standards,and the compound cost was reduced.
