摘要
研究了不同牌号的橡胶填充油对苯乙烯-乙烯/丁烯-苯乙烯共聚物(SEBS)力学性能的影响及以聚丙烯(PP)为改性剂对充油SEBS进行改性的效果。结果表明:随着填充油用量的增加,拉伸强度下降,弹性回复增加,断裂伸长率也增大。PP是充油SEBS体系的一种很好的相容剂,在体系中加入PP后,随着PP用量的增大,材料的拉伸强度的增大;断裂伸长率迅速下降;回弹性和熔体质量流动速率也迅速下降。
The effect of different varieties of rubber oil on the mechanical properties of styrene-ethylene/butylene-styrene （SEBS） triblock copolymer blend, and the that of PP, which was used as a modifier, on the modification of oil-extended SEBS were studied. The results indicated that with the increase of the content of the extender oil, the tensile strength decreased, while the elasticity increased and elongation at break improved. PP was a perfect compatibilizer for the oil-extended SEBS. With the increase of the content of PP, the tensile strength gradually increased, but the elongation at break, the elasticity and melt flow index decreased at the same time.
