IR在内胎中的应用

Application of IR to inner tube

对IR在轮胎内胎中的应用进行了试验研究。结果表明 ,用IR部分替代NR ,胶料的物理性能与原生产配方基本相同 ,试验胶料的工艺性能良好 ,成品性能达到国家标准要求 ;IR不经塑炼可直接用于混炼 ,提高了生产效率 ,降低了能耗 ;同时 ,IR的使用扩大了SR用量 ,可使每千克混炼胶原材料成本降低 0 .18元 。

The application of IR partly replacing NR to inner tube was investigated.The results showed that the processibility of test compound was very good,its physical properties were similar to those of original NR compound and the performance of finished product met the requirements in relavent national standard;the productivity improved and the energy consumption reduced because IR could be directly mixed without mastication;and the cost of mix could be reduced by 0 18 RMB yuan per kg.
