TOUGHENED EPOXY RESIN COMPOSITION HAVING GOOD INTERFICIAL ADHESIVENESS AND ITS PREPARATION

摘要

The present invention relates to a toughening epoxy resin composition having excellent interfacial adhesion and a method of manufacturing the same.;An object of the present invention is to improve the impact resistance of the resin in order to improve the brittle properties of the epoxy resin while providing a toughened epoxy resin composition and a method for producing the excellent epoxy adhesive composition and the cured product of the epoxy resin.;According to the present invention, 10 to 30% by weight of the reactive polyether ester copolymer represented by the following general formula (1) with the main component as the epoxy resin per 100% by weight of the total amount of the epoxy resin and the reactive polyether ester copolymer Toughened epoxy resin composition excellent in interfacial adhesion, characterized in that the dicyandiamide is included and the curing agent is included in the equivalent ratio.;However, m, n is an integer and the range is 100 ~ 200, x is 10 and, R is _{(CH 2) 4 O, (} CH 2) 6 O is one of the one selected.
