METHOD FOR PRODUCING UNDERWATER-HARDENING COMPOSITE MATERIAL COMPOSITION, AND METHOD FOR PRODUCING UNDERWATER-HARDENING CONSTRUCTION MATERIAL
To provide a method for producing a composite material composition capable of being hardened underwater at normal temperature, and capable of forming a hardened body excellent in water resistance, acid resistance, alkali resistance, adhesion strength, bending strength, and compressive strength; and to provide a method for producing an underwater-hardening construction material.SOLUTION: This invention relates to a method for producing an underwater-hardening composite material composition, obtained by mixing an organic amine hardener, a nonaqueous epoxy compound, and a reinforcer, the amine hardener having 4,500 mg/L of an organic nitrogen concentration at which an organic nitrogen is dissolved into water. Preferably, a compounding ratio of the organic amine hardener, the organic amine hardener and the nonaqueous epoxy compound is 0.7:1-1.3:1 by equivalent ratio.SELECTED DRAWING: None
【課題】常温で水中硬化が可能であり、耐水性、耐酸性、耐アルカリ性、接着強度、曲げ強度および圧縮強度に優れる硬化体を成形することができる複合体組成物の製造方法および水中硬化が可能な建設資材の製造方法の提供。【解決手段】水に溶け出す有機体窒素濃度が４５００ｍｇ／Ｌ以下の有機アミン系硬化剤、非水溶性エポキシ化合物および補強材を混練する水中硬化が可能な複合体組成物の製造方法であり、好ましくは、有機アミン系硬化剤と有機アミン系硬化剤と非水溶性ポキシ化合物の配合比が、当量比で、０．７：１〜１．３：１であることが好ましい。【選択図】なし
