中文摘要:
      目的 寻找合适的硫化剂制备具有良好回弹性的聚乳酸(PLA)基动态热塑性弹性体(TPV)。 方法 以丙烯酸酯橡胶(ACM)作为橡胶相,分别选用三巯基均三嗪(TCY)、六亚甲基二胺氨基甲酸盐(HDC)、N,N'-双肉桂醛缩-1,6-己二胺(DHD)作为ACM/PLA共混体系的硫化剂,研究这3种硫化剂与ACM或PLA混炼过程的扭矩曲线变化。结果 当每100 g橡胶-聚乳酸体系中添加0.75 g硫化剂时,该TPV的硬度适中,拉伸强度相对较高,断裂伸长率基本相当,永久变形率为最小(26%)。加入TCY硫化剂后,材料中的橡胶相由原来的球状颗粒转变为柱状颗粒,分布于PLA基体中。结论 TCY作为硫化剂能够制备得到具有良好力学性能的PLA基TPV。
英文摘要:
      The work aims to find a suitable vulcanizing agent to prepare poly(lactic acid) (PLA)-based dynamic vulcanizates (TPV) with good resilience. With acrylic rubber (ACM) as a rubbery phase, trithiocyanuric acid (TCY), hexamethylene diamine carbamate (HDC), and N,N’-dicinnamal-1,6-hexamethylenediamine (DHD) were respectively used as a vulcanizing agent for ACM/PLA blend system. The variation of torque curves of these three vulcanizing agents with ACM or PLA during melt-compounding was analyzed. TCY was found to be the most suitable vulcanizing agent for the ACM/PLA TPV system among these three vulcanizing agents. When the content of TCY was 0.75 g, the hardness of TPV was moderate, the tensile strength was high and the elongation at break was similar to others, but the rate of the permanent deformation was the smallest, only 26%. After addition of TCY, the morphology of rubbery phase in the TPV materials was changed from the original spherical shape to the cylindrical one, distributed in PLA matrix. TCY can be used as vulcanizing agent to prepare PLA-based TPV with good mechanical properties.
