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] and an imidazole compound as a component [B], and satisfies the following conditions (a)-(d). (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): The included amount of the component [B] is an amount such that the ratio of the number of imidazoles to the number of epoxide groups within the total epoxy resin is 0.01-0.06.
(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], et un composé imidazole en tant que composant [B], et satisfait les conditions (a) à (d) suivantes. (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) : La teneur en composant [B]est égale à une quantité telle que le rapport du nombre d'imidazole vis-à-vis du nombre de groupe époxy dans l'ensemble de la résine époxy est compris entre 0,01 et 0,06.
(JA) 高い耐熱性および弾性率と低着色性を両立するエポキシ樹脂硬化物が得られ、かつ繊維強化複合材料のマトリックス樹脂として用いたときに成形品表面に白色析出物を生じず、優れた外観を有するエポキシ樹脂組成物を提供する。 成分[A]としてエポキシ樹脂、成分[B]としてイミダゾール化合物を含み、下記条件(a)~(d)を満たすエポキシ樹脂組成物。 (a):成分[A]として[A1]イソシアヌル酸型エポキシ樹脂を、全エポキシ樹脂100質量部中10~40質量部含む。 (b):成分[A]として[A2]ビスフェノール型エポキシ樹脂を、全エポキシ樹脂100質量部中40~90質量部含む。 (c):[A2]の平均エポキシ当量が220~500g/eqである。 (d):成分[B]の含有量が、全エポキシ樹脂中のエポキシ基数に対するイミダゾール数の比が0.01~0.06となる量である。
