Retarding magnesium phosphate cement and preparation method thereof
The invention discloses delayed coagulation type magnesium phosphate cement and a preparation method thereof, and relates to the field of building materials. The delayed coagulation type magnesium phosphate cement comprises a main component and a function regulating component. Wherein the main components comprise, by mass, (1) 50%-75% of a magnesium raw material and (2) 25%-50% of phosphate, and the sum of the mass percent of the magnesium raw material and the mass percent of the phosphate is 100%. Besides, based on 100% of the mass of the magnesium raw material in the main components, a function regulating component is additionally added, and the doping amount of each component is as follows: (1) 2%-8% of a retarder, (2) 2%-10% of a temperature rise inhibitor and (3) 4%-12% of a complexing agent. The preparation method comprises the following steps: grinding the magnesian raw material, and metering and mixing various composition materials. Effective regulation and control of the setting time of the magnesium phosphate cement and collaborative development of the compressive strength are realized, and the method has a wide application prospect.
一种缓凝型磷酸镁水泥及其制备方法，涉及建筑材料领域。所述缓凝型磷酸镁水泥包括主要组分和功能调控组分。其中主要组分以质量百分比计量如下：(1)镁质原料50％‑75％，(2)磷酸盐25％‑50％，两者之和为100％。另外，按主要组分中镁质原料的质量为100％计，额外加入功能调控组分，各组分的掺量分别如下：(1)缓凝剂2％‑8％，(2)温升抑制剂2％‑10％，(3)络合剂4％‑12％。制备步骤包括：镁质原料粉磨、各种组成材料的计量与混合。本发明实现了磷酸镁水泥凝结时间的有效调控和抗压强度的协同发展，具有广阔应用前景。
