摘要
研究了乙烯 辛烯共聚物 (POE) /SBR共混物的力学性能和相态结构。结果表明 ,随着POE8180 (辛烯质量分数为 0 2 8) /SBR共混比 (除 5 0 /5 0外 )增大 ,共混物的力学性能提高 ;POE80 0 3(辛烯质量分数为0 18)用量不超过 40份时 ,随着POE80 0 3/SBR共混比增大 ,共混物的力学性能提高 ;POE80 0 3制成粘度较大的炭黑母料后再与SBR母炼胶共混 ,可提高共混物的力学性能 ;POE8180与SBR的共混温度为 12 0℃时共混物的综合力学性能最佳 ;POE8180 /SBR共混物为两相结构 ,POE8180 /SBR共混比为 40 /6
The mechanical properties and phase structure of POE/SBR blend were investigated.The results showed that the mechanical properties of POE8180/SBR blend improved as the proportion of POE8180 (the octylene content was m28%) increased except for the blend with the blending ratio of 50/50;the mechanical properties of POE8003/SBR blend improved as the proportion of POE8003 (the octylene content was m18%) increased up to 40;the mechanical properties of blend improved when POE8003 was mixed to form a carbon black masterbatch with high viscosity and then blended with SBR masterbatch;the optimum comprehensive mechanical properties of blend were obtained when POE8180 was blended with SBR at 120 ℃;and POE8180/SBR blend possessed two phase structure and existed as IPN structure when the blending ratio of POE8180/SBR was 40/60.
