PURPOSE: Provided are an epoxy resin composition which is formed by fine dispersing a low molecular weight wax component in a biphenyl epoxy resin, and thus has both adhesion and excellent mold releasing property, and a method for preparing the same. CONSTITUTION: The method comprises the steps of (i) completely fusing a phenol novolac-based curing agent in a reactor maintained at 120-140 deg.C, slowly adding 50-130 parts by weight of biphenyl epoxy resin(with respect to 200 parts by weight of the phenol novolac-based curing agent), fusion-mixing the curing agent and the biphenyl epoxy resin at the above temperature range for 20-60 minutes, and quenching the mixture at low temperature so as to obtain a resin masterbatch, and (ii) fusion-mixing the resin masterbatch with other components to obtain a final resin composition. |
