| 中文摘要: |
| 考察加拿大丁腈橡胶NBR801（丙烯腈含量40%）和NBR802（丙烯腈含量18%）在回转轴油封胶料中的应用。结果表明：主体材料采用NBR801/NBR802（并用比85/15）并用，补强剂采用滚筒法炭黑/半补强炉法炭黑（并用比45/25）并用，填充剂采用25份碳酸钙，硫黄用量2~3份，促进剂采用促进剂M/DM/D（并用比1/0.5/0.7）并用，增塑剂采用邻苯二甲酸二丁酯/松焦油（并用比10/2.5）并用，油封胶料的物理性能、耐磨性能、耐低温性能和耐油性能较好，成品油封性能达到使用要求。 |

| In this study，the application of Canadian nitrile rubber NBR801 (acrylonitrile content of 40%) and NBR802 (acrylonitrile content of 18%) in the rotary shaft oil seal compound was investigated. The optimized compound formulation was as follows： rubber material was NBR801/NBR802 at the blending ratio of 85/15，reinforcement system was blend of roller carbon black/semi-reinforcing furnace black with the ratio of 45/25，25 parts of calcium carbonate was applied as filler，sulfur dosage was 2 to 3 parts，accelerators M/DM/D were at the ratio of 1/0.5/0.7，and plasticizers were dibutyl phthalate and pine tar with the ratio of 10/2.5. The physical properties，wear resistance，low temperature resistance and oil resistance of the compound were excellent，the functional performance of finished seal fully met the application requirement. |
