炭黑N231在工程机械子午线轮胎胎面胶中的应用

Application of Carbon Black N231 in the Tread Compound of OTR Tire

对工程机械子午线轮胎胎面胶配方进行改进。结果表明:使用炭黑N231代替炭黑N220,并适当增大炭黑用量,能够有效提高胶料的邵尔A型硬度、定伸应力、抗崩花掉块性能和抗切割性能,降低生热,延长轮胎的使用寿命。

In this study, the tread compound formulation for OTR tire was modified. The results show that, by using carbon black N231 instead of carbon black N220 and properly increasing the carbon black loading level, the Shore A hardness, modulus, chip resistance and cut resistance of the tread compound were increased, the heat build- up was reduced and the tire service life was extended.
