Abstract
PURPOSE: To produce a molding resing which gives molded articles having high reliability and output, by a method wherein an epoxy resin and a phenolic resin hardener (one of them being solid and the other being liquid) are melt-mixed, and then an inorg. filler and a curing promotor are melt-mixed with the resulting mixture.
CONSTITUTION: In a process for the production of a molding resin employing an epoxy resin compsn. contg. an epoxy resin having at least two epoxy groups per molecule, a phenolic resin hardener having at least two hydroxyl groups per molecule, a curing promotor and an inorg. filler powder, at least one component selected from the epoxy resin and the phenolic resin hardener is solid and the other is liquid or viscous. A mixture of the epoxy resin and the phenolic resin hardener excluding the curing promotor is previously melt-mixed and then the whole epoxy resin compsn. contg. 55W70vol% (based on the entire volume of the compsn.) said inorg. filler powder, is melt-mixed.
