摘要
采用恒速型双毛细管流变仪,研究了线型和星型苯乙烯-乙烯/丁烯-苯乙烯(SEBS)充入石蜡油和环烷油后的流变性能及其挤出物外观的畸变情况,并分析了其畸变的扰动源。结果表明,充油可以明显降低SEBS的熔体黏度和弹性,改善SEBS挤出物的外观畸变,充入石蜡油的SEBS熔体弹性降低更明显,其改善畸变的效果比环烷油好。
We used the constant speed type double capillary rheometer to study the influences of white oil on distortion of extrudate appearance,and analyzed the distortion source.Respectively filled linear and star styrene-ethylene/butylene-styrene(SEBS) with paraffin oil and naphthenic oil by a simple mixing.It showed that filling SEBS with oil could obviously decreased the melt viscosity and melt elasticity,while it had a better effect on the appearance defects of the extrudate.Filling SEBS with paraffin oil,the melt elasticity decreased more obviously,while it had a better effect on the appearance defects of the extrudate.
