The invention discloses a temperature-resistant high-gas-barrier dynamically vulcanized alloy for a tire lining layer. The temperature-resistant high-gas-barrier dynamically vulcanized alloy comprises 20-100 parts of rubber, 5-50 parts of polyamide PA, 0-20 parts of a compatilizer, 0-30 parts of a plasticizer, 0-10 parts of a vulcanizing agent, 0-10 parts of zinc oxide, 0-10 parts of a lubricant and 0-3 parts of an antioxidant. The dynamically vulcanized alloy provided by the invention has the advantages of favorable processability, low cost, environment friendliness, recyclability, temperature resistance and high gas barrier property, and can replace the traditional tire butyl rubber airtight layer. Compared with the performance of a traditional static vulcanized butyl rubber tire inner liner, the air tightness of the tire lining layer is improved by 7-10 times, and the weight (thickness) of the tire lining layer is reduced by 60%. In addition, when the tire lining layer is prepared, the tire lining layer can be directly formed by adopting an extrusion calendering or blow molding method, a vulcanization link is not needed, the technological process is shortened, and the processing energy consumption is greatly reduced.

    一种用于轮胎内衬层耐温高气体阻隔动态硫化合金,包括橡胶20‑100份、聚酰胺PA 5‑50份、相容剂0‑20份、增塑剂0‑30份、硫化剂0‑10份、氧化锌0‑10份、润滑剂0‑10份,抗氧剂0‑3份。本发明制备出的动态硫化合金具有良好的加工性能,成本低,绿色环保,可回收利用,耐温,具有高气体阻隔性能,可替代传统的轮胎丁基橡胶气密层。与传统静态硫化丁基橡胶轮胎气密层相比,气密性提高了7‑10倍,重量(厚度)减少了60%。而且在制备轮胎内衬层时可采用挤出压延或吹塑成型的方法直接成型,不需要硫化环节,缩短了工艺流程,大大降低了加工能耗。
