Waterborne epoxy polymer and high-toughness cement repair mortar containing same
The invention discloses a waterborne epoxy polymer and high-toughness cement repair mortar containing the same, and belongs to the field of building materials. The waterborne epoxy polymer is prepared by the following steps: reacting bisphenol A, epoxy resin B, epoxy resin C, hydroxyalkyl secondary amine and a monomer X, and then adding a hydrophilic prepolymer E to continuously react; the terminal hydroxyl group of the bisphenol A is connected with the terminal epoxy group of the epoxy resin B or the epoxy resin C through reaction; the amino group at the X end of the monomer is connected with the epoxy group at the end of the epoxy resin B or the epoxy resin C through reaction, and the hydroxyalkyl secondary amine is reacted with the epoxy group at the end of the epoxy resin B or the epoxy resin C to form a sealed end; isocyanate groups in the hydrophilic prepolymer E are connected with active hydroxyl groups in reactants through reaction. The high-toughness cement repair mortar containing the waterborne epoxy polymer is simple and rapid to prepare, convenient to use, excellent in mechanical property, high in bonding strength and good in anti-permeability performance, and the materials are all waterborne, non-toxic and environmentally friendly.
本发明公开了一种水性环氧聚合物及包含其的高韧性水泥修复砂浆，属于建筑材料领域。所述水性环氧聚合物，由双酚A、环氧树脂B、环氧树脂C、羟烷基仲胺及单体X反应后，再加入亲水性预聚体E继续反应制得；所述双酚A的端羟基与环氧树脂B或环氧树脂C的端环氧基反应相连；所述单体X端胺基与环氧树脂B或环氧树脂C的端环氧基反应相连，所述羟烷基仲胺与环氧树脂B或环氧树脂C的端环氧基反应形成封端；所述亲水性预聚体E中的异氰酸酯基与反应物中的活性羟基反应相连。所述包含水性环氧聚合物的高韧性水泥修复砂浆，制备简单快捷，使用方便，力学性能优异，粘结强度高、抗渗性能好，材料为全水性化，无毒环保。
