摘  要：通过试验分析了乳液混合液固含量、聚灰比和淀粉醚对漆膜干燥时间、砂浆凝结时间、力学性能和砂浆施工性的影响。结果表明，环氧树脂乳液混合物固含量越高，其漆膜的干燥时间越短。随着聚灰比的增大，水性环氧水泥砂浆的凝结时间越长。当聚灰比为5%～10%和10%～15%时，水性环氧水泥砂浆分别可以达到Ⅱ级标准和Ⅰ级标准。当淀粉醚的掺量在0.3‰～0.5‰时，可以显著改善水性环氧砂浆的抗流挂和涂抹顺滑性。

Abstract: The influence of emulsion liquid mixture solid content, polymer-cement ratio and starch ether on the drying time of paint coatings and setting time, mechanical properties and workability of mortar is analyzed. The results show that the higher the solids content of the epoxy emulsion mixture is, the shorter the dry time of the paint coatings is. The setting time of the waterborne epoxy cement mortar get longer with increasing of the polymer-cement ratio. When the polymer-cement ratio is 5%～10% or 10%～15%, the waterborne epoxy cement mortar can respectively reach grade II and grade I standard. When the dosage of starch ether is between 0.3‰～0.5‰, the anti-sagging and smearing smoothness of waterborne epoxy cement mortarr can be significantly improved.
