The compounded epoxy resin used as a raw material for casting epoxy resins is a two-component epoxy resin with excellent storage stability that is separated into an epoxy resin component side and a curing agent component side to prevent a curing reaction from occurring. Compositions are known. However, even in the case of such a two-component type, a reaction occurs during storage on the epoxy resin component side where no curing agent is present, resulting in an increase in viscosity, or gelation or hardening occurs when the temperature rises, causing the liquid resin to deteriorate. becomes unusable.

Based on the recognition that the reaction during storage of the epoxy resin component of a casting epoxy resin composition containing additives such as colorants and inorganic fillers is due to the polymerization reaction caused by 0H7j, OF: Added flame retardant that does not contain
This has a remarkable effect on storage stability, especially at high temperatures of 50 to 150°C, and achieves the above object.

抑制されたことを示している。In order to confirm the effects of the present invention, epoxy resin compositions of Examples and Comparative Examples having the formulations shown in Table 1 were prepared. Of MIft in Table 1, Epicoat 828 is an epoxy resin and is a product name of Ciel Epokin Co., Ltd., decabromodiphenyl oxide and tetrabromo bisphenol A are flame retardants, antimony trioxide is a flame retardant aid, and Hiezrefx RD-8 is a filler. Carbon black, a product name of Ryumori Co., Ltd., is a coloring agent. Figure 1 shows the changes in viscosity over time when both epoxy resin compositions in Table 1 were stored at 50°C (dashed line) and 100°C (solid line), with line 11.12 representing the example and line 21.22 representing the example. A comparative example shows that the increase in viscosity was suppressed by using decabromodiphenyl oxide, which does not contain an OH group, as an IT fuel instead of tetrabromobisphenol, which contains an OH group.
