摘要
研究了自制的相容剂聚碳酸酯聚氨酯(PCU)对PC/TPU共混体系相容性及力学性能的影响。结果表明,相容剂PCU的加入,促使共混体系中PC的玻璃化温度进一步降低,增强了两相间的界面黏结作用,改善了PC/TPU之间的相容性;PCU的加入,提高了PC/TPU共混物的冲击性能,当相容剂用量为6份时,缺口冲击强度达到最大值,为未加相容剂时的5倍。
The effects of the self-made compatibilizer PC-PU （PCU） on the compatibility and mechanical properties of PC/TPU blend ere studied. The results showed the addition of PCU decreased the Tg of PC, increased the interfacial bonding force between the two phases, resulted in improving the compatibility of PC/TPU blend. The addition of PCU improved the impact strength of the blend. When the content of PCU was 6 phr, the impact strength was the maximum, being 5 times of that of PC/TPU.
