| 中文摘要: |
| 采用机械薄通法对氢化丁腈橡胶（HNBR）硫化胶进行改性回收，并将改性HNBR再生胶填充到HNBR胶料中，研究改性剂品种、用量以及再生胶用量对胶料性能的影响。结果表明：添加用交联型改性剂改性的HNBR再生胶可提高胶料的硬度和300%定伸应力；添加用软化型改性剂改性的HNBR再生胶可提高胶料的拉断伸长率和撕裂强度；添加用偶联剂Si69和松香改性的HNBR再生胶的胶料拉伸强度相对较高；用于改性HNBR再生胶的松香和偶联剂Si69适宜用量分别为2～7和2～6份；在HNBR胶料中掺用改性HNBR再生胶的适宜用量为20～50份。 |
| 英文摘要: |
| In this study，the hydrogenated nitrile rubber（HNBR） vulcanizate was recycled and modified by the mechanical thin pass method，and the modified HNBR recycled rubber was filled into HNBR compound. The effects of type and addition amount of modifier，and addition level of recycled rubber on the properties of HNBR compound were investigated. The results showed that the hardness and tensile modulus at 300% elongation of HNBR compound with the recycled HNBR modified by crosslinking type modifier increased. The elongation at break and tear strength of HNBR compound with the recycled HNBR modified by softening type modifier were improved. With addition of silane coupling agent Si69 and rosin in the recycled HNBR modification，the tensile strength of HNBR compound was relatively high，and the suitable addition levels of Si69 and rosin were 2 ～ 7 and 2 ～ 6 phr，respectively. The optimized addition levels of recycled HNBR in the compound were 20～50 phr. |
