摘　　要：对丙烯酸乳液、醋酸乙烯-乙烯共聚乳液(VAE乳液)及自制水性环氧乳液改性砂浆中一系列影响因素进行研究。结果表明:自制的水性环氧改性砂浆具有显著提升砂浆的抗压、抗折及粘结性能,其掺入砂浆比例为10%,室温20℃,湿度55%,养护28天,抗压强度达到最大为75.9MPa,抗折强度为19.4MPa,粘结强度为5.5MPa。In this paper, acrylic emulsion, vinyl acetate ethylene eopolymer emulsion （VAE emulsion） and self-made waterborne epoxy resin emulsion modified cement mortar in a series of influencing factors were studied. The results show that the self-made modified waterborne epoxy mortar can significantly improve mortar compressive and flexural strength and adhesion properties. The mortar ratio was 10% at room temperature, 20 degrees celsius, humidity of 55% maintenance 28 days, reached the maximum compressive strength 75.9MPa, flexural strength 19.4MPa, the bonding strength of 5.SMPao
