Organic/inorganic synergistic modified basic magnesium sulfate cement and preparation method thereof
The invention discloses organic/inorganic synergistic modified basic magnesium sulfate cement and a preparation method thereof, and belongs to the technical field of building materials. The organic/inorganic synergistically modified basic magnesium sulfate cement is formed by synergistically modifying fly ash-basic magnesium sulfate cement by taking epoxy resin as an organic modifier and basic magnesium sulfate cement seed crystal emulsion as an inorganic modifier. Through the synergistic effect of the epoxy resin and the seed crystal emulsion, the mechanical property and the water resistance of the fly ash-basic magnesium sulfate cement are remarkably improved, so that the application range of the magnesium cement is expanded. The prepared fly ash-basic magnesium sulfate cement synergistically modified by the epoxy resin/basic magnesium sulfate cement seed crystal has the compressive strength of 52.9 MPa after being cured for 28 days, and has the softening coefficient of 0.92 after being soaked in water for 28 days.
本发明公开了一种有机/无机协同改性碱式硫酸镁水泥及制备方法，属于建筑材料技术领域。所述有机/无机协同改性碱式硫酸镁水泥通过以环氧树脂为有机改性剂，碱式硫酸镁水泥晶种乳液为无机改性剂，二者协同改性粉煤灰‑碱式硫酸镁水泥而形成。本发明通过环氧树脂和晶种乳液的协同作用，使得粉煤灰‑碱式硫酸镁水泥的力学性能及耐水性得到了显著提升，从而扩大镁水泥的应用范围。本发明制备的环氧树脂/碱式硫酸镁水泥晶种协同改性的粉煤灰‑碱式硫酸镁水泥养护28天抗压强度达52.9MPa，泡水28天后软化系数达0.92。
