TPU及TPU-g-MAH增韧废旧ABS的研究

Recycled ABS Toughened by TPU and TPU-g-MAH

研究了热塑性聚氨酯TPU及TPU-g-MAH对废旧ABS增韧效果的影响。结果表明:当TPU的用量为15份时,共混物缺口冲击强度为13.3 KJ/m2,比改性前提高了26.7%,当TPU-g-MAH的用量为20份,DCP用量为0.5份时,共混物缺口冲击强度为20.2 KJ/m2,比改性前提高了92.4%。

The toughening effects of TPU and TPU-g-MAH to recycled ABS were studied, The results showed that, when the addition level of TPU was 15 phr, the notched impact strength reached 13.3 KJ/m2 which increased by 26.7 %; When the addition level of TPU-g-MAH was 20 phr, DCP was 0.5 phr, the notched impact strength reached 20.2 KJ/m2 which increased by 92.4 %.
