METHOD FOR CURING EPOXY RESIN IN SHORT TIME AND METHOD FOR ABSORBING ELECTROMAGNETIC WAVE BY EPOXY RESIN CURED SUBSTANCE OBTAINED BY THE CURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for curing in a short time by irradiating a microwave to an epoxy resin composition, and further to utilize a curing substance containing an accelerator for generation of heat as an absorber of an electromagnetic wave. SOLUTION: The method is to cure an epoxy resin composition constituting of a curing agent component cured by reacting an epoxy resin having 1.8 or more epoxy groups with an epoxy group under the condition of ordinary temperature or elevating temperature in a short time by irradiating a microwave of frequency 300 MHz to 30 GHz, and to use the cured substance containing an accelerator for generation of heat as an absorber of an electromagnetic wave.
