摘　　要：研究炭黑N339在全钢载重子午线轮胎胎面胶中的应用。结果表明:与加入52份炭黑N220的胶料相比,采用炭黑N339替代50%或全部替代炭黑N220的胶料的硫化速率增大,硫化胶的硬度和300%定伸应力增大,压缩生热分别降低3.8和4.5℃,耐磨性能提高;当炭黑N339和炭黑N220用量比为1/1时,硫化胶的滚动阻力和动态生热低,成品轮胎的耐久性能优异,高速性能相当。The application of carbon black N339 in the tread compound of all-steel truck and bus radial tires was studied.The results showed that,compared with the compound filled with 52 phr carbon black N220,the vulcanization rate of the compounds in which 50%or all of carbon black N220 was replaced by carbon black N339 increased,the hardness and modulus at 300%elongation of the vulcanizates increased,the compression heat build-up decreased by 3.8 and 4.5℃,respectively,and wear resistance was improved.When the mass ratio of carbon black N339 to carbon black N220 was 1/1,the rolling resistance of the vulcanizate decreased,dynamic heat build-up decreased,and the durability of the finished tire was excellent,with similar high-speed performance compared with the finished tire having the tread compound with all carbon black N220.
