| 中文摘要: |
| 研究均匀剂H40MSF在全钢子午线轮胎胎面胶中的应用，并与国内外同类产品进行对比。结果表明：加入均匀剂H40MSF，胶料的门尼粘度减小，t5延长，加工安全性提高，FL和Fmax减小；硫化胶的拉伸强度、拉断伸长率和撕裂强度增大，炭黑分散性改善，耐磨、耐疲劳和抗切割性能提高，压缩生热降低，损耗因子减小，滚动阻力降低；均匀剂H40MSF在胶料中耐迁移，不易变色，污染小，其综合性能优于国产均匀剂A，与进口均匀剂40MSF相近。 |
| 英文摘要: |
| The application of homogenizer H40MSF in the tread compound of all-steel radial tire was studied and compared with similar products at home and abroad.The results showed that by adding homogenizer H40MSF，the Mooney viscosity of the compound decreased，t5 was prolonged，the processing safety improved，FL and Fmax were decreased.The tensile strength，elongation at break and tear strength of the vulcanizate increased，the dispersion of carbon black was improved，the wear resistance，fatigue resistance and cutting resistance increased，the compression heat build-up reduced，the loss factor and rolling resistance were decreased.Homogenizer H40MSF was resistant to migration in the compound，was not easy to change color，and had little pollution.Its comprehensive performance was better than that of domestic homogenizer A，and was similar to that of imported homogenizer 40MSF. |
