| 中文摘要: |
| 研究环氧化度为50%的环氧化天然橡胶（ENR50）在全钢载重子午线轮胎胎面胶中的应用。结果表明：使用ENR50等量替代部分天然橡胶能够进一步促进白炭黑分散，使得胎面胶的定伸应力和拉伸强度略有下降，拉断伸长率和硬度有所提高；并且可以显著提高胶料的耐磨性能和压缩疲劳性能，同时降低生热。 |
| 英文摘要: |
| The application of epoxidized natural rubber with 50% mol epoxidation（ENR50） in the tread compound of truck and bus radial tire was investigated.The results showed that silica dispersion was enhanced by replacing part of natural rubber with the same amount of ENR50.The modulus and tensile strength of the tread compound were declined slightly，but elongation at break and hardness were improved. More importantly，the wear resistance and compression fatigue properties of the tread compound were enhanced significantly，and heat build-up of the tread compound was reduced. |
