 Abstract:In order to improve the corona resistance properties of polyesterimide resin nanoAl2O3 sol was prepared by microemulsionhydrothermal method and dispersed into polyesterimide resin solution by mechanical blending then nanoAl2O3 hybrid polyesterimide composite material was prepared The results show that the nanoparticles are dispersed in the polyesterimide matrix With the increase of doping amount the corona resistance of the composites increases but the dielectric strength decreases When the doping amount was 12% its coronaresistant life is 5 times more than pure polyesterimide resin and the dielectric strength is 1752kV/mmWith the increase of the doping amount the dielectric loss of the material is little affected but the dielectric coefficient increases slightly The nanoAl2O3 particles in matrix have little effect on the heat resistance of the material 

摘要:
 摘要:为了提高聚酯亚胺树脂耐电晕性能,采用微乳化-相转变法制备纳米Al2O3溶胶,并通过机械共混,使其分散到聚酯亚胺树脂溶液中,制备了纳米Al2O3杂化聚酯亚胺复合材料。实验结果表明:纳米粒子在聚酯亚胺基体中分散均匀;随掺杂量的提高,复合材料的耐电晕性呈上升趋势,但介电强度呈下降趋势,当纳米掺杂质量分数为12%时,耐电晕寿命达到纯聚酯亚胺树脂的5倍,介电强度达到1752kV/mm;纳米Al2O3对复合材料的介电损耗影响很小,但介电系数随掺杂量增加而略有升高;引入纳米Al2O3对材料耐热性影响不大。
