摘　　要：新能源汽车驱动电机对内部绝缘纸的性能要求较高。为解决现有新能源汽车驱动电机用绝缘纸电气性能不稳定、热性能和机械性能一般等问题,以植物纤维及改性聚酰亚胺纤维为主材,以剑麻纤维、纳米纤维素等为辅材,以纳米氧化铝等为功能填料,制备了一种专门应用于新能源汽车驱动电机的绝缘纸。对该绝缘纸的综合性能进行试验分析,结果表明,当植物纤维在整体绝缘纸中的质量占比为75%时,该绝缘纸的介电强度等综合性能最为优异。The new energy vehicle drive motor has high requirements for the performance of internal insulating paper.In order to solve the problems of unstable electrical properties,general thermal and mechanical properties of the existing insulating paper for the drive motor of new energy vehicles,a kind of insulating paper specially applied to the drive motor of new energy vehicles was prepared with plant fiber and modified polyimide fiber as the main material,sisal fiber,nanoculosic fiber as the auxiliary material,and nano alumina as the functional filler.The results show that when the mass proportion of plant fiber in the whole insulating paper is 75%,the dielectric strength and other comprehensive properties of the insulating paper are the best.
