电机用环氧绝缘材料相容性的研究OA

Epoxy insulating materials often need to be blended and compatibilized with other epoxy materials during preparation and application to meet service requirements,where compatibility is a critical factor determining the physicochemical properties and mechanical performance of blended materials.In the study,two types(1#and 2#)of commonly used two-component epoxy resin systems were mixed using specific processes,and their properties and micro-morphologies were characterized.The results showed that the mechanical properties of compatibilized blended and cured samples fell basically between those of the two pure samples,and no obvious linear interface was observed after sequential curing,indicating good compatibility between the two components.All prepared samples met relevant technical requirements.Although sequential curing required longer time,it exhibited superior performance.Considering all factors,samples obtained by sequential curing were finally selected.The research results provide a reference for the study of epoxy resin compatibility.
