新型气体阻隔材料AM-100在轮胎气密层中的应用

Application of New Gas-Barrier Material AM-100 in Tire Innerliner

研究新型气体阻隔材料AM-100在轮胎气密层中的应用。结果表明:随着AM-100用量的增大,胶料的门尼粘度减小,门尼焦烧时间缩短;硫化胶的硬度和回弹值增大,10%和100%拉伸模量呈增大趋势,拉伸强度变化不大;AM-100在胶料中的分散性较好;当AM-100用量为63份时,硫化胶的气密性提高,且生产成本明显降低。

The application of new gas-barrier material AM-100 in tire innerliner was investigated. The results showed that, as the addition level of AM-100 increased, the Mooney viscosity of the compound decreased and Mooney scorch time was shortened. The hardness and resilience of the vulcanizates increased, tensile modulus at 10% and 100% elongation increased, and tensile strength changed little. The dispersion of AM-100 in the compound was good. When the addition level of AM-100 was 63 phr, the air tightness of the vulcanizates was improved, and the production cost was reduced significantly.
