Abstract
PURPOSE: To provide the titled molding material which inhibits the corrosion of metallic electronic parts such as a sealed aluminum electrode, by a method wherein a small amount of phophoric acid (or a salt thereof) is added to an electronic part sealing compsn. consisting of an epoxy resin, a hardener and a filler.
CONSTITUTION: 100pts.wt. of a mixt. (A) consisting of an epoxy resin (i) and a hardener (ii) for the epoxy resin (e.g. a phenolic novolak, an amine or an acid anhydride), 150W400pts.wt. of an inorg. filler (B) ( e.g. crystalline silica powder or silica glass powder) and at least 0.1pt.wt. of phoshporic acid (or a salt thereof) (C) (e.g. phosphoric anhydride, orthophosphoric acid, or a metal salt or an ammonium salt thereof) are mixed together by means of a mixer and then melt-mixed by means of heating rollers, etc. to obtain the titled molding materials.
