摘　　要：研究液体氟橡胶用量对丙烯酸酯橡胶(ACM)/液体氟橡胶并用胶性能的影响。结果表明:加入液体氟橡胶,并用胶的t10延长,t90缩短,FL和Fmax减小,加工性能提升;ACM与液体氟橡胶相容性良好,并用胶的耐寒性能有所下降;随着液体氟橡胶用量的增大,并用胶的物理性能、热空气老化性能、热稳定性能和耐油性能先提高后降低,压缩永久变形增幅增大;当液体氟橡胶用量为5份时,并用胶的综合性能较佳。The effect of the liquid fluororubber amount on the properties of acrylate rubber(ACM)/liquid fluororubber blends was investigated.The results showed that,with the addition of liquid fluororubber,t10 of the blends was prolonged,t90 was shortened,FL and Fmax were reduced,and the processability was improved.The compatibility between ACM and liquid fluororubber was good,and the cold resistance of the blends was reduced.With the increase of the liquid fluororubber amount,the physical properties,thermal air aging properties,thermal stability and oil resistance of the blends increased first and then decreased,and the increase rate of compression set increased.When the amount of liquid fluororubber was 5 phr,the comprehensive properties of the compound were better.
