PROBLEM TO BE SOLVED: To provide a casting epoxy resin compsn. obtd. as a product with stabilized pot life and quality while suppressing the variation in the reactivity of an epoxy resin and preventing agglomeration of alumina particles, and a method therefor. SOLUTION: An epoxy resin is blended with alumina particles and aluminum sulfate to obtain a casting epoxy resin compsn. The alumina particles are mixed using a high-speed mixer provided with a turbine impeller having a high shear force according to a method of preparing the casting epoxy resin compsn. |
