| 中文摘要: |
| 对比研究炭黑N550和浅色填料（碱性白炭黑AS-70、沉淀法白炭黑255、硅酸铝钾GW-9、硅酸铝钾BS-280和矽丽粉VM-56）填充氢化丁腈橡（HNBR）胶料的性能，并制备浅色高性能HNBR密封材料。结果表明：与炭黑N550填充胶料相比，沉淀法白炭黑255填充胶料的门尼粘度明显增大，t10和t90缩短；碱性白炭黑AS-70填充胶料的门尼粘度相差不大，FL和Fmax略增大；其他3种浅色填料填充胶料的门尼粘度、FL和Fmax较小，三者水平相当；浅色填料填充硫化胶的耐热老化性能较好；碱性白炭黑AS-70填充硫化胶的压缩永久变形最小；采用碱性白炭黑AS-70制备的浅色高性能HNBR密封材料综合性能优异且各项性能满足相关标准要求。 |
| 英文摘要: |
| The properties of hydrogenated nitrile butadiene rubber（HNBR） compounds filled by carbon black N550 and light colored fillers（alkaline silica AS-70，precipitation silica 255，aluminum-potassium silicate GW-9，aluminum-potassium silicate BS-280 and aktisil VM-56） were compared，and the light colored high performance HNBR sealing material was prepared.The results showed that，compared with the compound filled with carbon black N550，the Mooney viscosity of the compound filled with precipitation silica 255 was significantly increased，t10 and t90 were shortened.The Mooney viscosity of compound filled by alkaline silica AS-70 had little difference，FL and Fmax increased slightly.The Mooney viscosity，FL and Fmax of the compounds filled with other three light colored fillers were relatively small，and the level was comparable.The thermal aging resistance of vulcanizate filled with light colored fillers was better.The compression set of vulcanizate filled with alkaline AS-70 was the minimum.The light colored high performance HNBR sealing material prepared by alkaline silica AS-70 had excellent comprehensive properties，and the properties met the requirements of relative standards. |
