摘要
为了改善双马来酰亚胺树脂(BMI)固有的一些缺点,本文以含有氨基的聚硅氧烷(PSi-NH2)作为胺源,以苯酚作为酚源,通过化学合成的方法制备了结构中含有超支化聚硅氧烷的苯并噁嗪单体(PSi-BOZ),并以其作为改性体系对BMI进行改性,得到了一种新型的PSi-BOZ/BMI共混材料,并研究了PSi-BOZ的添加对BMI固化反应动力学及冲击性能的影响,为新型BMI树脂材料的开发提供了思路。
In order to improve the poor toughness and heat resistance of bismaleimide(BMI)resin,benzoxazine monomer(BOZ)containing polysiloxane(PSi-BOZ)was synthesized via a chemical method,the hyperbranched polysiloxane with amino terminal groups(PSi-NH2)and the phenol were chosen as the raw materials.The PSi-BOZ was then used as modification system to add into BMI,and PSi-BOZ/BMI composite with excellent comprehensive performance and good manufacturability was obtained.The influence of the addition of PSi-BOZ on the curing reaction kinetics and impact strength of BMI were also studied.This study is aiming to provide an idea for the development of new BMI resin materials.
