摘　　要：研究了纤维素醚MFS6003对聚合物水泥防水浆料性能的影响。结果表明,随着MFS6003用量的增加,聚合物水泥防水浆料的施工性能、抗流挂性和憎水能力显著提高,对聚合物水泥防水浆料的抗压、抗折强度,横向变形能力及抗渗性能几乎没有影响。当MFS6003用量为0.07%时,制得的防水浆料抗渗压力大于0.5 MPa,横向变形能力为2.5 mm,28 d收缩率为0.28%,符合JC/T2090—2011《聚合物水泥防水浆料》中I型产品的要求。The effects of the cellulose ether MFS6003 on the properties of polymer cementitious waterproof slurry were studied.The results showed that the workability,sag-resistance and hydrophobicity of polymer cementitious waterproof slurry are increased clearly with the increase of MFS6003 dosage.Cellulose ether has verylitlle effect on the compressive strength,flexual strength,transverse deformation and impermeability of polymer cementitious waterproof slurry.When the amount of MFS6003 is 0.07%,the impermeability of waterproof slurry is more than 0.5 MPa,the transverse deformation capacity is 2.5 mm,and the 28 d shrinkage rate is0.28%.Meet the requirements of Type I products in JC/T 2090—2011 "Polymer Modified Cement Slurry for Waterproof".
