Abstract:
(EN) Provided is an epoxy resin composition with which an epoxy resin cured product with a high heat resistance and elastic modulus as well as a low colorability can be obtained, said epoxy resin composition not producing white deposits on a surface of a molded good when used as a matrix resin of a fiber-reinforced composite material, and thus having a superior external appearance. The epoxy resin composition includes an epoxy resin as a component [A], [B1] an aromatic urea and/or [B2] an imidazole compound as a component [B], and a boric acid ester compound as a component [C], wherein the included amount of dicyandiamide is 0.5 parts by mass or less per 100 parts by mass of the total epoxy resin, and the epoxy resin composition satisfies the following statement (i) or statement (ii). (i) The following condition (a), condition (b), and condition (c) are satisfied. (ii) The following condition (d) and condition (e) are satisfied. (a): For the component [A], [A1] an isocyanuric acid type epoxy resin is included at 10-40 parts by mass within 100 parts by mass of the total epoxy resin. (b) : For the component [A], [A2] a bisphenol type epoxy resin is included at 40-90 parts by mass within 100 parts by mass of the total epoxy resin. (c): The average epoxy equivalent weight of [A2] is 220-500g/eq. (d): For the component [A], [A3] an epoxy resin indicated by a specific general formula is included at 50-100 parts by mass within 100 parts by mass of the total epoxy resin. (e): The average epoxy equivalent weight of the total epoxy resin is 165-265g/eq.
(FR) L'invention fournit une composition de résine époxy avec laquelle est obtenu un produit durci de résine époxy conciliant une résistance à la chaleur ainsi qu'un module d'élasticité élevés et de faibles propriétés de coloration, qui ne produit pas de dépôt blanc à la surface d'un article moulé lors d'une mise en œuvre en tant que résine de matrice pour un matériau composite renforcé par des fibres, et qui présente une excellente apparence. Cette composition de résine époxy contient une résine époxy en tant que composant [A], une urée aromatique [B1] et/ou un composé imidazole [B2] en tant que composant [B], et un composé ester d'acide borique en tant que composant [C], présente une teneur en dicyandiamide inférieure ou égale à 0,5 partie en masse pour 100 parties en masse de l'ensemble de la résine époxy, et satisfait le point <i> ou <ii> suivant. <i> Les conditions (a), (b) et (c) suivantes sont satisfaites. <ii> Les conditions (d) et (e) sont satisfaites. (a) : Une résine époxy de type acide isocyanurique [A1], est contenue en tant que composant [A] à raison de 10 à 40 parties en masse pour 100 parties en masse de l'ensemble de la résine époxy. (b) : Une résine époxy de type bisphénol [A2], est contenue en tant que composant [A] à raison de 40 à 90 parties en masse pour 100 parties en masse de l'ensemble de la résine époxy. (c) L'équivalent époxy moyen de [A2] est compris entre 220 et 500g/eq. (d) : Une résine époxy représentée par la formule générale spécifique [A3], est contenue en tant que composant [A] à raison de 50 à 100 parties en masse pour 100 parties en masse de l'ensemble de la résine époxy. (e) : L'équivalent époxy moyen de l'ensemble de la résine époxy, est compris entre 165~265g/eq.
