| 中文摘要: |
| 研究新型耐迁移大分子防老剂BH-F77（简称防老剂BH-F77）在天然橡胶（NR）中的应用。结果表明：与传统防老剂6PPD相比，防老剂BH-F77的相对分子质量较高，热稳定性较好，金属元素种类较多且含量较高，耐迁移性能较优且不易变色；随着防老剂BH-F77用量的增大，NR胶料的流动性和加工安全性变差，硫化速度加快，硫化胶的邵尔A型硬度和100%定伸应力增大，拉伸强度和拉断伸长率减小，耐臭氧老化性能下降。 |
| 英文摘要: |
| The application performance of a new type of migration resistant macromolecular antioxidant BH-F77（abbreviation antioxidant BH-F77）in natural rubber（NR） was studied.The results showed that compared with traditional antioxidant 6PPD，antioxidant BH-F77 had a higher relative molecular weight，better thermal stability，more types and contents of metal elements，better migration resistance and less discoloration.As the dosage of antioxidant BH-F77 increased，the flowability and processing safety of NR compound were deteriorated，the vulcanization rate was accelerated，the Shore A hardness and modulus at 100% of the vulcanizate increased，the tensile strength and elongation at break reduced and the ozone aging resistance decreased. |
