| 中文摘要: |
| 研究湿磨法超细绢云母在全钢子午线轮胎气密层胶中的应用。结果表明：采用绢云母部分替代炭黑N660后，混炼胶的正硫化时间延长，加工安全性提高，力学损耗降低；随着绢云母用量的增大，硫化胶的邵尔A型硬度和拉伸强度变化不大，100%定伸应力、300%定伸应力和撕裂强度呈增大趋势，拉断伸长率呈减小趋势，耐疲劳性能下降，气密性提高；综合考虑气密层胶的性能要求，绢云母用量宜为20份，同时可大幅降低生产成本。 |
| 英文摘要: |
| The application of wet-grinding superfine sericite in inner liner compound of all-steel radial tire was studied.The results showed that，after partially replacing carbon black N660 with sericite，the positive curing time of compound was prolonged，the processing safety was improved，and the mechanical loss was reduced.As the amount of sericite increasing，the Shore A hardness and tensile strength of vulcanizate have changed little.The 100% tensile stress，300% tensile stress and tear strength showed an increasing trend，while the elongation at break showed a decreasing trend，the fatigue resistance decreased and the airtightness improved.Taking into account the performance requirements of inner liner compound，the appropriate amount of sericite was 20 phr，which could significantly reduce production costs. |
