Abstract

PURPOSE: The titled molded article useful for heat insulation, sealing, fixing electrical parts, etc., having functions such as keeping warm, sound insulation, weight saving, etc., obtained by blending an expandable epoxy resin composition containing a blowing agent wint a specific thermoplastic resin, followed by molding it into various kinds of shapes.
CONSTITUTION: (A) an epoxy resin having preferably ≥35 equivalent/kg epoxide, liquid or semisolid at room temperature, is blended with (B) a high-molecular- weight thermoplastic resin having a molecular weight of ≥10,000, consisting of a repeating unit shown by the formula derived from bisphenol A and epichlorohydrin, (C) a curing agent (e.g., dicyandiamide, etc.) exhibiting activity at high temperature, stable at room temperature, and (D) a blowing agent (e.g., azodicarbonamide, etc.) in such a way that the amount of the component B is 30W60wt% based on the total amounts of the components A, B, and C, the amount of the component C is 0.5W20wt% based on 100pts.wt. of the components A and B, or 0.3W1.5 opoxy equivalent, and the amount of the component D is an amount to give an expansion magnification of about 3W10 times, to hive the desired composition, and, if necessary, the composition is bonded to a reinforcing material and molded in an integrated way.
