Improving the surface insulating performance of epoxy resin/Al(2)O(3) composite materials by extending chain of liquid epoxy resin with Me-THPA

Basin-type insulators are made by epoxy resin composite materials. Curing defects are easily formed in basin-type insulators, and degrade their insulating performances. High curing exothermic rates of epoxy resin composite materials have deemed as the main cause of curing defects formation. In this...
