Title
(EN) CURING AGENT FOR EPOXY RESIN
(FR) AGENT DE DURCISSEMENT POUR RÉSINE ÉPOXYDE
(JA) エポキシ樹脂用硬化剤
Abstract
(EN) One problem addressed by the present invention is to provide a curing agent for an epoxy resin that yields a resin composition having low viscosity and rapid curing and a cured product having high impact strength. The present invention provides a curing agent for an epoxy resin, etc., in which there are combined (A) a liquid aromatic polyamine and (B) a solid aromatic polyamine including a secondary amino group, and in which (C) an aliphatic cyclic polyamine is furthermore used in combination when the (B) solid aromatic amine including a secondary amino group does not include (B1) a solid aromatic amine in which the number of secondary amino groups is greater than the total number of primary amino groups and tertiary amino groups.
(FR) Un problème abordé par la présente invention consiste à fournir un agent de durcissement pour une résine époxyde qui produit une composition de résine présentant une faible viscosité et un durcissement rapide, et un produit durci présentant une résistance élevée aux chocs. La présente invention concerne un agent de durcissement pour résine époxyde, etc., dans lequel sont combinées une polyamine aromatique liquide (A) et une polyamine aromatique solide (B) comprenant un groupe amino secondaire, et dans lequel une polyamine cyclique aliphatique (C) est en outre utilisée en combinaison lorsque l'amine aromatique solide (B) comprenant un groupe amino secondaire ne comprend pas d'amine aromatique solide (B1) dans laquelle le nombre de groupes amino secondaires est supérieur au nombre total de groupes amino primaires et de groupes amino tertiaires.
(JA) 本発明の課題の一つは、低粘度かつ速硬化性の樹脂組成物及び高い衝撃強度を有する硬化物をもたらす、エポキシ樹脂用硬化剤を提供することである。本発明は、(A)液状芳香族ポリアミンと(B)二級アミノ基を含む固形芳香族ポリアミンとを組み合わせ、(B)二級アミノ基を含む固形芳香族アミンが、(B1)二級アミノ基の数が一級アミノ基と三級アミノ基との合計数より多い固形芳香族アミンを含まない場合、さらに(C)脂肪族環状ポリアミンを組み合わせて使用する、エポキシ樹脂用硬化剤等を提供する。
