Retarding type low-carbon magnesium phosphate composite material and preparation method thereof
The invention discloses a delayed coagulation type low-carbon magnesium phosphate composite material and a preparation method thereof, and belongs to the field of civil engineering materials. The retarding type low-carbon magnesium phosphate composite material comprises a main component and a function regulating component. Wherein the main components are metered in percentage by mass as follows: (1) 30%-65% of a magnesium material, (2) 25%-40% of phosphate and (3) 10%-30% of a mineral admixture, and the sum of the mass percentages of the magnesium material, the phosphate and the mineral admixture is 100%. Besides, based on 100% of the mass of the magnesium material in the main components, a function regulating component is additionally added, and the doping amount of each component is as follows: (1) 4%-10% of a dispersing agent, (2) 2%-6% of a surfactant, (3) 1%-5% of a chelating agent, (4) 2%-8% of a complexing agent and (5) 1%-15% of a retarder. The preparation method comprises the following steps: (1) grinding the raw materials; and (2) mixing. The magnesium phosphate composite material disclosed by the invention has the characteristics of long setting time, relatively large adjustable range and the like, meanwhile, the carbon emission of the magnesium phosphate composite material is far lower than that of a traditional magnesium phosphate cementing material, and the magnesium phosphate composite material has a wide application prospect.
一种缓凝型低碳磷酸镁复合材料及其制备方法，属于土木工程材料领域。所述缓凝型低碳磷酸镁复合材料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)镁质材料30％‑65％，(2)磷酸盐25％‑40％，(3)矿物掺合料10％‑30％，三者之和为100％。另外，按主要组分中镁质材料的质量为100％计，额外加入功能调控组分，各组分的掺量分别如下：(1)分散剂4％‑10％，(2)表面活性剂2％‑6％，(3)螯合剂1％‑5％，(4)络合剂2％‑8％，(5)缓凝剂1％‑15％。制备步骤具体如下：①原材料粉磨加工和②混料。本发明的磷酸镁复合材料具有凝结时间长且可调控范围较大等特点，同时其碳排放量远低于传统磷酸镁胶凝材料的碳排放，具有广阔应用前景。
