Title
(DE) EPOXIDHARZZUSAMMENSETZUNG, PREPREG, FASERVERSTÄRKTES VERBUNDMATERIAL UND GEHÄUSE FÜR ELEKTRONISCHE UND ELEKTRISCHE KOMPONENTEN
(EN) EPOXY RESIN COMPOSITION, PREPREG, FIBER-REINFORCED COMPOSITE MATERIAL, AND HOUSING FOR ELECTRICAL OR ELECTRONIC EQUIPMENT
(FR) COMPOSITION DE RÉSINE ÉPOXY, PRÉ-IMPRÉGNÉ, MATIÈRE COMPOSITE RENFORCÉE PAR DES FIBRES, ET BOÎTIER POUR UN ÉQUIPEMENT ÉLECTRIQUE OU ÉLECTRONIQUE
Abstract
(EN) To provide an epoxy-resin composition and prepreg for producing a fiber-reinforced composite material which exhibits excellent curability and has excellent flame retardance and heat resistance, as well as to provide fiber-reinforced composite materials produced using the prepreg and to provide housing for electronic/electrical devices. The epoxy resin composition contains component (A): a phosphorus compound; component (B): an epoxy resin which has at least three epoxy groups in the molecule, and which does not correspond to component (A) nor include component (A); component (C): an epoxy resin curing agent which does not have a urea structure in the molecule; and component (D): a dimethylurea compound represented by formula (a) (in formula (a), "R" is a hydrogen atom or an alkyl group having any number of 1 to 10 carbons).
(FR) L'invention concerne : une composition de résine époxy et un pré-imprégné qui présentent une excellente capacité de durcissement et qui peuvent chacun produire une matière composite renforcée par des fibres ayant une excellente capacité retardatrice de flamme et une excellente résistance à la chaleur ; et une matière composite renforcée par des fibres et un boîtier pour un équipement électrique ou électronique qui sont obtenus à l'aide du pré-imprégné. La composition de résine époxy comprend (A) un composé du phosphore, (B) une résine époxy qui comporte au moins trois groupes époxy par molécule et qui n'est pas le composant (A) et qui ne contient pas le composant (A), (C) un agent de durcissement pour des résines époxy qui ne présente pas de structure d'urée dans la molécule, et (D) un composé diméthylurée représenté par la formule (a) [dans laquelle R représente un atome d'hydrogène ou alkyle en C1-10].
