摘　　要：用纳米氧化铝(Al_2O_3)对环氧多胶粉云母带进行了改性,制得双面玻璃布补强的纳米复合环氧多胶粉云母带,探讨了样品的性能,并与5440-1桐马酸酐环氧多胶粉云母带进行比较。研究结果表明,在云母带的粘合剂中引入13.5%(wt,质量分数)的纳米Al_2O_3,制得的纳米复合环氧多胶粉云母带在155℃条件下,弯曲强度达到108.00/MPa,电寿命有了较大幅度的提高,达到89.0h,导热系数为0.34W/m·℃,分别比5440-1桐马酸酐环氧多胶粉云母带提高了170%、129%和26%,具有较好的性能。Resin-rich mica tape was modified with nano-Al2 O3 and double-sided glass fabric backed epoxy nanocomposite resin-rich mica tape was trial-produced.The performance of trial product was investigated and compared with 5440-1 tung oil-maleic imide anhydride epoxy resin-rich mica tape.The results showed that by introducing13.5 wt% of nano-Al2 O3 into the adhesive of mica tape,under the condition of 155℃,the bending strength reached108.00/MPa,the electrical life increased to 89.0 h,the thermal conductivity was 0.34 W/m·℃,increased than that5440-1 tung oil-maleic imide anhydride epoxy resin-rich mica tape 170%,129% and 26%respectively,which presented the good performance.
