摘要
利用E-39D双酚A环氧树脂与酸酐固化剂METHPA、α-Al2O3填料及其他添加助剂,经机械共混固化后可得到具有优异电气性能和耐侯性能的灌封体系。探讨了影响环氧树脂灌封材料工艺性的各种因素;通过填料表面偶联处理实现了填料粒子在环氧基体中的良好分散,得出了具有良好工艺性的环氧灌封材料的工艺条件。
A casting resin system which has excellent electrical and temperature-impacting resistance properties is got by blending bisphenol A-based epoxy resin (E-39D) with curing agent (METHPA) ,α-Al_2O_3 fillers and other additive agents.The factors that influence on the processibility of casting system are studied in this paper.α-Al_2O_3 fillers were well dispersed in epoxy matrix by surface coupling disposal. The appropriate processing conditions are also subjected in this paper.
