Abstract:
      In this study，the effects of the dosage and blending ratio of carbon black N990 and barium sulfate on the vulcanization properties，low temperature resistance，physical properties，hot air aging resistance， medium resistance and compression set of carbon black N990 and barium sulfate filled fluoroether rubber compound were investigated by a designed experiment with 9 test formulations with different dosage and blending ratio of carbon black N990/barium sulfate. The results showed that，the dosage and blending ratio of carbon black N990/barium sulfate had a great influence on the properties of fluoroether rubber vulcanizate. With the increase of the dosage of carbon black N990/barium sulfate，the mechanical properties of fluoroether rubber vulcanizate were improved. The low temperature resistance of fluoroether rubber vulcanizate was mainly determined by the molecular structure of the rubber，and while the rubber content of the vulcanizate increased，the low temperature resistance of the vulcanizate was improved. The medium resistance of fluoroether rubber vulcanizate was related to the crosslinking degree. When the dosage of carbon black N990/barium sulfate increased，the crosslinking network formed by the fluoroether rubber and reinforcing fillers was more dense， and the medium resistance of the fluoroether rubber vulcanizate was improved.
