改性氯磺化聚乙烯橡胶和空气阻止剂NM360在全钢载重子午线轮胎气密层胶中的应用

Application of Modified Chlorosulfonyl-polyethylene Rubber and Air Barrier Agent NM360 in Inner Liner Compound of Truck and Bus Radial Tire

研究改性氯磺化聚乙烯橡胶(MCSM)和空气阻止剂NM360在全钢载重子午线轮胎气密层胶中的应用。结果表明,以MCSM部分替代溴化丁基橡胶,同时加入空气阻止剂NM360,并适当调整填充体系和硫化体系,胶料的硫化特性、物理性能和气密性能变化不大,工艺性能优异,成品轮胎的耐久性能满足使用要求,生产成本明显降低。

The application of modified chlorosulfonyl-polyethylene rubber （MCSM） and air barrieragent NMg60 in the inner liner compound of truck and bus radial tire was investigated. The results showed that, by using MCSM to partially replace bromobutyl rubber, adding NM360, and adjusting the filler system and vulcanization system properly, the curing behavior, physical properties and air tight- ness of the compound changed little, the processibility was good,the endurance of the finished tire met the service requirements, and the cost of materials was reduced significantly.
