摘要 本研究以聚丙烯(PP)为基体、氢化苯乙烯-丁二烯嵌段共聚物(SEBS)和β成核剂(β-NAs)为增韧剂,采用熔融共混法制备了PP/SEBS/β-NAs共混物,研究了SEBS和β-NAs对PP的协同增韧作用并探究了增韧机理。结果表明:当添加20%SEBS和0.05%β-NAs时,得到的PP/SEBS/β-NAs共混物样品的冲击强度达到了76.1 kJ/m2,较纯PP(3.9 kJ/m2)提高了1 851.3%。SEBS和β-NAs的协同效应不仅能够增韧PP,还能够提高其加工性能。β-NAs的加入会诱导所得样品的脆-韧转变行为在低SEBS含量下提前发生。增韧机理为,由于β-NAs的加入,PP/SEBS/β-NAs共混物体系中大部分α晶转化为β晶,致使PP晶粒细化,SEBS相尺寸变小、分散更均匀。在外力作用下样品中的SEBS相充当应力集中点,不仅SEBS相内部及SEBS相和PP的界面层会发生空穴化,还会诱导样品中的PP基体发生大量的剪切屈服形变,这些过程会吸收大量能量,赋予PP/SEBS/β-NAs共混物良好的韧性。

Abstract: In this work,using polypropylene (PP) as the matrix,hydrogenated styrene-butadiene block copolymer (SEBS) and β nucleating agents (β-NAs) as toughening agents,PP/SEBS/β-NAs blends were prepared by melt blending method. The synergistic toughening effect of SEBS and β-NAs on PP,and the toughening mechanism were investigated. The results showed that the impact strength of the obtained PP/SEBS/β-NAs blends reached 76.1 kJ/m2 at 20% SEBS and 0.05% β-NAs,which was 1 851.3% higher than that of pure PP (3.9 kJ/m2). The synergistic effect of SEBS and β-NAs not only toughened PP,but also improved the processing properties. The addition of β-NAs induced an earlier brittle-tough transition behaviour of the obtained PP/SEBS/β-NAs blends at low SEBS content. The toughening mechanism could be explained that due to the addition of β-NAs,most of the α crystals in the PP/SEBS/β-NAs blends were converted into β crystals,resulting in a finer size of PP grains,smaller size and more uniform dispersion of the SEBS phases. The SEBS phases acted as the stress concentration points,which not only cavitated inside the SEBS phase and the interface layer between the SEBS phase and PP,but also induced a large amount of shear yield deformation of the PP matrix in the sample,and these processes absorbed a large amount of energy,giving the PP/SEBS/β-NAs blends good toughness.
