有机锌在全钢载重子午线轮胎气密层胶中的应用

Application of Organic Zinc in Inner Liner Compound of Truck and Bus Radial Tire

介绍有机锌的作用机理,研究有机锌在全钢载重子午线轮胎气密层胶中的应用,并与间接法氧化锌对比。结果表明:与间接法氧化锌相比,有机锌的锌和重金属质量分数小,密度小,比表面积大;与添加间接法氧化锌的气密层胶相比,添加有机锌的气密层胶的硫化特性、物理性能和耐热老化性能相当,气密性好。

This paper introduced the functional mechanism of organic zinc in rubber material,and presented the study on the application of organic zinc in the inner liner compound of truck and bus radial tire with comparison to indirect zinc oxide. The results showed that compared with indirect zinc oxide,the zinc content and heavy metal content in the organic zinc were lower,the density of organic zinc was smaller, and the specific surface area was larger. Compared with the indirect zinc oxide filled inner liner compound, the curing characteristics,physical properties and heat aging resistance of organic zinc filled inner liner compound were similar,and the air tightness was good.
