摘　　要：优化无内胎轮胎气密层胶配方,以减少胎里露线问题。结果表明:通过减小软化剂用量、适当调整硫化体系和加入防焦剂,气密层胶的门尼粘度增大,硫化速度加快,硬度和300%定伸应力略有升高,成品轮胎胎里露线产生率降低,轮胎的静态和动态气密性变化不大,使用寿命延长。In this study, the formulation of an inner liner compound of tubeless tire was optimized in order to reduce the issue of exposed cord. In the optimized formulation, the amount of softener was reduced, the curing system was adjusted and anti-scorch agent was added. The experimental testing results showed that after the optimization Money viscosity of the compound increased, the hardness and modulus at 300% elongation of the vulcanizates increased slightly, the defect rate of exposed cord was reduced, the static and dynamic air tightness changed little, and the tire service life was extended.
