| 中文摘要: |
| 研究高岭土在矿山全钢巨型工程机械子午线轮胎胎侧胶中的应用。结果表明：以高岭土替代部分炭黑N330后，混炼胶的门尼粘度减小，硫化速度变化不大；与未添加高岭土的硫化胶相比，添加未改性高岭土的硫化胶的硬度变化不大，拉伸强度和拉断伸长率增大，300%定伸应力和60 ℃时的损耗因子减小，压缩生热降低，添加硅烷偶联剂Si69改性高岭土的硫化胶的100%和300%定伸应力增大；添加未改性高岭土的硫化胶和添加硅烷偶联剂Si69改性高岭土的硫化胶的裂口增长速度减小，且随着改性高岭土用量的增大，硫化胶的裂口增长速度减小；添加未改性高岭土的硫化胶的撕裂能增大，而添加硅烷偶联剂Si69改性高岭土的硫化胶的撕裂能与之相比减小，且改性高岭土用量越大，硫化胶的撕裂能越小；高岭土基本不影响硫化胶的耐臭氧老化性能和炭黑在橡胶基体中的分散性。 |

| The application of kaolin in sidewall compound of all-steel giant off-the-road radial tire used in mine was studied.The results showed that replacing a portion of carbon black N330 with kaolin，the Mooney viscosity of the compound was reduced，and the vulcanization rate had a little change.Compared with the vulcanizate without kaolin，the hardness of the vulcanizate with unmodified kaolin did not change much，the tensile strength and elongation at break increased，the moduli at 300% and loss factor at 60 ℃ decreased，the compression heat generation decreased，and the modulus at 100% and 300% of the vulcanizates with silane coupling agent Si69 modified kaolin increased.The crack growth rates of the vulcanizates with unmodified kaolin and with silane coupling agent Si69 modified kaolin decreased，and with the increase of the modified kaolin dosage，the crack growth rate of the vulcanizate decreased.The tear resistance of the vulcanizate with unmodified kaolin was improved，but compare with it，the tear energy of the vulcanizate with silane coupling agent Si69 modified kaolin was reduced.The greater the modified kaolin dosage was，the lower the tear energy of the vulcanizate was.Kaolin did not significantly affect the ozone aging resistance of the vulcanizate and the dispersion of carbon black in rubber mix. |
