水性エポキシド樹脂組成物

Water-based epoxide resin composition

Abstract

(57)【要約】 【目的】 本発明の目的は、ポリエポキシド化合物と新 規合成ポリアミン誘導体を組み合わせて、優れた耐水性 と耐酸性を持つ硬化塗膜を与える水性エポキシド樹脂組 成物を提供することである。 【構成】 水性エポキシド樹脂組成物は、分子内に平均 1.5個以上のエポキシ基を持つポリエポキシド化合物 と新規合成ポリアミン誘導体とから構成される。新規合 成ポリアミン誘導体は、マンニッヒ塩基を含むポリアミ ンに疎水性ジエポキシドと親水性ジエポキシドを、又は マンニッヒ塩基を含むポリアミンに疎水性ジエポキシド と親水性ジエポキシドとモノエポキシド及びアクリロニ トリルから選択される単独又はこれらの混合物とを反応 させて造られる。
PROBLEM TO BE SOLVED: To obtain a water-based epoxide resin composition which can give coating films excellent in water resistance and acid resistance and is useful for coating materials, adhesives and binders by mixing a polyepoxide with a specified polyamine derivative. SOLUTION: This composition essentially consists of a polyepoxide having at least 1.5 glycidyl groups on the average per molecule and a polyamine derivative prepared by reacting polyamine containing a Mannich base obtained by reacting a phenolic compound with a carbonyl compound and a polyamine having at least two amino groups which are prim. and/or sec. amino groups with a diepoxide having an aromatic or alicyclic structure in the molecule and having two glycidyl groups and a diepoxide being a diglycidyl ether of polyoxyethylene glycol.
