摘　　要：采用相反转法制备高稳定性环氧树脂乳液,在环氧树脂乳液改性水泥砂浆方面,着重探讨了改性水泥砂浆的力学性能和吸水性,在环氧树脂乳液改性水泥浆体方面,进行了减水试验,分析得出不同聚合物掺量水泥浆体的减水效果,同时进行水泥凝结时间试验。研究表明,聚合物的存在一方面延缓了水泥的水化速度,另一方面改善了硬化浆体的毛细孔结构。环氧树脂乳液改性水泥砂浆的力学性能得到提高,抗渗性得到改善。The phase inversion method is used to prepare the high-stability epoxy resin emulsion. The article focuses discussion on the mechanical property and water absorption of modified cement mortar in the aspect of epoxy resin emulsion modified cement mortar, introduces the water reduction test in the aspects of epoxy resin emulsion cement paste, analyzes to achieve the water reduction effects of the cement pastes with the different polymer contents, and also describes the cement setting time test. The study results show the existence of polymer not only delays the hydration speed of cement, but also improves the pore structure of hardened paste. The mechanical property of epoxy resin emulsion modified cement mortar is improved and the impermeability is improved.
