耐裂口高气密性全钢子午线轮胎气密层胶配方的开发

Development of Formulation of Inner Liner Compound for All-steel Radial Tire with Crack Resistance and High Air Tightness

介绍耐裂口高气密性全钢子午线轮胎气密层胶配方的开发。试验结果表明:通过添加无机填料Suprex,减小炭黑N660和环保油用量,并调整硫化体系,胶料的门尼焦烧时间和硫化时间延长,硫化胶的物理性能、气密性、耐屈挠和耐裂口性能提高;成品轮胎的耐久性能、气密性和耐氮氧老化性能提高。

The development of formulation of the inner liner compound for all-steel radial tire with crack resistance and high air tightness was introduced.The test results showed that,by adding inorganic filler Suprex,reducing the amount of carbon black N660 and environmentally friendly oil,and adjusting the vulcanization system,the Mooney scorch time and vulcanization time of the compound were prolonged,and the physical properties,air tightness,flexural resistance and crack resistance of the vulcanizate were improved.Correspondingly,the durability,air tightness,nitrogen and oxygen aging resistance of the finished tire were improved.
