摘要

本文用甲氧基聚乙二醇(mPEG-550)对双酚A (DEGBA)型环氧树脂二缩水甘油酯进行了改性。接枝环氧树脂的加入有效地提高了环氧材料的冲击韧性。同时，接枝环氧树脂的加入可以提高环氧材料的抗裂性能。当接枝环氧质量分数达到10%时，包埋不锈钢块的环氧样品在-60℃下保持完整。接枝环氧树脂的粘度低于原环氧树脂，有利于高频电力变压器的铸造工艺。综上所述，含部分接枝环氧树脂的环氧材料可以满足高频变压器的封装要求。

The epoxy packaging materials modified by flexible monohydroxy polyether chain for high frequency power transformer

In this manuscript, the diglycidyl ether of bisphenol A (DEGBA) type epoxy resin was modified with methoxy-polyethylene glycol (mPEG-550). The impact toughness of the epoxy materials was effectively increased with the adding of grafting epoxy. Meanwhile, the addition of grafting epoxy can improve the cracking resistance property of the epoxy materials. When the mass fraction of grafting epoxy reached 10%, the epoxy sample embedded with the stainless-steel block remained intact in -60°C. And the viscosity of grafting epoxy was lower than the original epoxy resin, which facilitated the casting process of the high frequency power transformer. Above all, the epoxy material containing partial grafting epoxy can meet the encapsulate requirements of high-frequency transformers.
