【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。更多还原

【Abstract】 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 T_g 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.更多还原
