Retarder of potassium magnesium phosphate cementing material, raw materials, preparation method and application of retarder
The invention discloses a retarder of a potassium magnesium phosphate cementing material, raw materials, a preparation method and application of the retarder. The retarder of the potassium magnesium phosphate cementing material comprises a compound containing a chelating group. According to the invention, the retarder containing the chelating group is added into the raw materials of the magnesium potassium phosphate cementing material, so that the coagulation time of the magnesium potassium phosphate cementing material can be prolonged according to engineering requirements, and meanwhile, the strength of the magnesium potassium phosphate cementing material after coagulation is ensured, so that the magnesium potassium phosphate cementing material can be suitable for different engineering operations.
本申请公开了一种磷酸钾镁胶凝材料的缓凝剂及原料、制备方法及其应用，所述磷酸钾镁胶凝材料的缓凝剂包括含螯合基团的化合物。本申请中通过在磷酸钾镁胶凝材料的原料中加入含螯合基团的缓凝剂，可根据工程需要延长磷酸钾镁胶凝材料的凝结时间，同时保证了磷酸钾镁胶凝材料凝结后的强度，使磷酸钾镁胶凝材料可以适用于不同的工程作业中。
