| 研究不同门尼粘度26型FKM在单用与并用时胶料的加工性能、物理性能和制品外观。结果表明：FKM胶料的挤出性能随着其门尼粘度提高而降低；单用门尼粘度[ML（1＋10）121 ℃]（以下简称门尼粘度）为60的FKM的胶料的门尼粘度高，混炼能耗大；与单用门尼粘度为40的FKM的胶料相比，门尼粘度为60与20的FKM并用比为1/1的胶料的流动性较好；FKM胶料的拉伸性能随着其门尼粘度的提高而提高，耐热老化性能无显著变化；随着高门尼粘度FKM并用比的增大，胶料的物理性能总体提高；当FKM胶料的门尼粘度为50以上时，可消除胶料加工时窝气和粘模等缺陷，当门尼粘度进一步提高，胶料的流动性变差，胶料不适宜生产薄垫等制品。 |

| The processabilities，physical properties and product appearances of single and blend 26-type Fluororubber（FKM） compounds with different FKM Mooney viscosities were investigated.The results showed that the extrusion processability of FKM compound decreased with the Mooney viscosity increasd.The FKM compound with FKM Mooney viscosity [ML（1＋10）121 ℃] （hereinafter referred to as Mooney viscosity） of 60 exhibited high Mooney viscosity and high mixing energy consumption.Compared with the FKM compound with FKM Mooney viscosity of 40，the FKM compound with FKM Mooney viscosities of 60 and 20 at a blend ratio of 1/1 showed better flowability.The tensile properties of FKM compound improved with increasing Mooney viscosity，while the heat aging resistance showed no significant change.As the blend ratio of FKM with high Mooney viscosity increased，the physical properties of the compound generally improved.When the Mooney viscosity of the compound reached 50 or above，the defects such as air trapping and mold sticking during processing were eliminated.However，a further increase in Mooney viscosity resulted in poorer flowability，the compound was unsuitable for producing thin gasket products. |
