| Abstract: |
| The influence of processing aid DF on the processibility and physical properties of ACM compound was investigated，and a comparison test was made on processing aid DF，normal processing aid——stearic acid，and imported processing aid WB.The results showed that the processibility of ACM compound was significantly improved by adding 1 phr of DF （e.g.unsticking to mill roll；lower Mooney viscosity and energy consumption），while the better mechanical properties，hot air and hot oil aging properties，and compression set of ACM vulcanizate were affected little.It was found from the analysis on TEM that the dispersion of carbon black in ACM compound was improved by adding DF.And it was indicated through the analysis of dynamic visco-elastic spectrum that Tg of ACM vulcanizate with 1 phr of DF was 7.2 ℃ lower than that of ACM vulcanizate without DF，thus the cold resistance of ACM vulcanizate was effectively improved. |
