摘　　要：采用不同于桐油酸酐胶黏剂且具有较高热变形温度的黏合剂制备了JF5440-1G高机械强度多胶粉云母带,对该云母带的常规性能进行了研究。结果表明,该云母带固化后在155℃下的弯曲强度不低于100MPa,在50-120℃其导热系数为0.31-0.32W/（m·K）,各项性能均达到IEC60371-3-6技术指标要求。A JF5440-1G high mechanical strength resin-rich mica tape was prepared using an epoxy adhesive which had high heat distortion temperature and was different from tung oil-bismaleimide-maleic anhydride, and its basic conventional properties were investigated. The results show that the flexural strength at 155 ℃ of the cured mica laminate is no less than 100MPa, the thermal conductivity is between 0.31W/（m·K） and 0.32W/（m·K） from 50 ℃ to 120 ℃, and various properties can meet the technical requirements of IEC 60371-3-6.
