WATER-DISPERSED EPOXY-AMINE ADDITIVE RESIN COMPOSITION, METHOD FOR PRODUCING SAME, PREPREG, AND FIBER-REINFORCED COMPOSITE MATERIAL

摘要

The purpose of the present invention is to provide a water-dispersed epoxy-amine additive resin composition which is highly reactive, is capable of improving adhesion between reinforcing fibers and a resin in a fiber-reinforced composite material, and is particularly useful as a sizing agent. The present invention pertains to a water-dispersed epoxy-amine additive resin composition characterized by containing a surfactant and an epoxy-amine additive represented by formula (I), and by the epoxy-amine additive being dispersed in a water-based medium. (In formula (I), each R1 may be the same or different, and represents a bivalent organic group having a carbon atom at the bonding sites with the nitrogen atoms depicted in the formula. X represents a single bond or a bivalent group having one or more atoms. q represents an integer of 1 or higher.)
