弹性体/无机纳米粒子复合体系增强增韧回收ABS树脂

Recycled ABS Resin Toughened and Reinforced by Elastomer/Inorganic Nano-Particle Composite System

分别研究了弹性体和无机纳米粒子对回收丙烯腈-丁二烯-苯乙烯共聚物（ABS）的增韧.结果表明：弹性体能使回收ABS树脂的韧性得到恢复,但导致刚性下降;无机纳米粒子对ABS树脂的增韧能力有限,但能增加ABS的刚性.最后采用弹性体/无机纳米粒子复合体系改性回收ABS树脂,添加质量分数5％～8％的高胶粉和质量分数2％～3％无机纳米粒子时,实现了对回收ABS树脂的增强增韧.

The toughening of elastomer and inorganic nano-particle to recycled ABS was studied respectively.The results show that elastomer restores the toughness of recycles ABS,but leads to decrease of rigidity,meanwhile inorganic nano-particle can increase the toughness partly,also leads to increases of rigidity.Finally recycled ABS is modified by elastomer/inorganic nano-particle composite system.When 5％～8％ ABS rubber powder and 2％ ～3％ inorganic particle are added,the recycled ABS resin is toughened and reinforced.
