| 中文摘要: |
| 对对-叔丁基苯酚甲醛树脂和对-叔辛基苯酚甲醛树脂对丁苯橡胶的流变性能、混炼功耗和物理性能的影响进行了研究。结果表明：加入树脂后，胶料的表观粘度、表观切应力下降，流动性能改善，挤出物外观质量变好，混炼功耗减少；随着树脂用量增加，效果更加明显；树脂用量少时，对硫化胶物理性能无不良影响，用量超过10份时，混炼出现严重的粘辊现象。 |
| 英文摘要: |
| A study has been made of the effects of p-tert-butyl phenol-formaldehyde resin and p-tert-octyl phenol-formaldehyde resin on the rheological and physical properties of SBR as well as on the power consumption for mixing.The result shows that by the addition of the resins the stock becomes one with reduced apparent viscosity，lowered apparent shear stress，improved flow behavior，better extrudate appearance and decreased mixing power consumption，and with the increase of the resin amount，the effect is more outstanding；a lower resin concentration gives no adverse effect on the properties of the vulcanisate and a resin concentration over 10 phr will result in a phenomenon of serious sticking-to-mill. |
