摘　　要：以硫铝酸盐水泥为基材,聚合物选用聚乙烯醇,并掺加硅烷偶联剂制备出抗弯强度达165 MPa以上,抗压强度超过267 MPa的高强SAC-MDF水泥材料,并优化出一套这种材料的适宜的制备工艺参数。另外,极少量的硅烷偶联剂能显著提高SAC-MDF水泥的抗弯强度和韧性,增幅分别达49.76％和14.55％。Using sulphoaluminate cement as base material, polyvinyl alcohol as polymer, and adding in silane coupling agent, high strength SAC-MDF cement with bending strength greater than 165MPa and compression strength greater than 267MPa can be produced. Process parameters for producing such kind of material have been optimized. It is noticeable that a bit of silane coupling agent can raise bending strength and toughness of SAC-MDF cement remarkably, and the increment can reach 49.76% and 14.55% respectively.
