摘要： A method for preparing an epoxy resin composition is disclosed. The method comprises mixing an epoxy resin selected from the group consisting of bisphenol A epoxy resin, bisphenol F epoxy resin, novolac based resin, cycloaliphatic epoxy resin, and a combination thereof in the range of 35-65% w/w, and an anhydride curing agent selected from the group consisting of glutaric anhydride, dodecenyl succinic anhydride, nonenyl succinic anhydride, and a combination thereof, in the range of 35-65% w/w while continuously stirring at a temperature in the range of 15-100 ° C for 15-120 minutes; adding to the mixture, one or more accelerator selected from the group consisting of amine, a metal halide, a phosphine, an acetylacetonate, an imidazole compound and a combination thereof, in the range of 0.3-1.5% by weight of the mixture and one or more filler selected from the group consisting of silica, wollastonite and a combination thereof, in the range of 190-230 % by weight of the mixture; and curing the mixture obtained after step (b) at 80 ° C-140 ° C for 10 minutes to 10 hours to obtain the epoxy resin composition. The weight loss of the composition obtained from the disclosed method is less than 1.8% after aging for 1000 hrs at 180 ° C based on IEC 60216.
