| 摘 要： | 以氮苯基马来酰亚胺(NPMI)为耐热组分,合成了耐热改性树脂SMIA(NPMI、苯乙烯、丙烯腈三元共聚物)并将其应用于丙烯腈-丁二烯-苯乙烯塑料(ABS)。研究结果表明,NPMI可大幅度提高ABS的热变形温度,但NPMI在SMIA树脂中的质量分数超过30%时,SMIA树脂与ABS胶粉的相容性降低会导致耐热ABS的冲击强度降低,使用抗冲改性剂可在一定程度上改善ABS的冲击强度。SMIA还可使耐热ABS的流动性能得以提高,而且加入SMIA越多,这种作用越明显。

| Abstract: | Series of heat-resistant SMIA resins were synthesized by using NPMI as functional components.Then SMIA terpolymers were applied to ABS.The results showed that NPMI could greatly improve the heat distortion temperature of ABS.When the mass fraction of NPMI was more than 30% in SMIA resin,the compatibility between SMIA resin and ABS rubber became poor,which led to lower impact strength of the heat-resistant ABS.To some extent,impact modifier could improve the impact strength of the heat resistant ABS.The liquidity of the heat-resistant ABS could also be increased by modifying with SMIA resin,and the more SMIA resin added,the more obvious the effect was. |
