高苯乙烯树脂/NBR共混物性能研究

研究高苯乙烯树脂(HSR)/NBR共混比对HSR/NBR共混物性能的影响。结果表明，随着HSR/NBR共混比的增大，共混物邵尔A型硬度、撕裂强度和压缩永久变形增大，拉伸强度先减小后增大，拉断伸长率减小，耐油性能下降；与NBR胶料相比，HSR/NBR共混物的挺性提高。;The effect of the high styrene resin(HSR)/NBR blending ratio on the properties of HSR/NBR blend was investigated.The results showed that，as the HSR/NBR blending ratio increased，the Shore A hardness，tear strength and compression set of HSR/NBR blend increased，the tensile strength increased at first and then decreased，and the elongation at break and oil resistance decreased；the HSR/NBR blend possessed better stiffness，when compared to the NBR compound
