Magnesium oxychloride cement and preparation method thereof
The invention belongs to the technical field of inorganic cementing materials, and particularly relates to magnesium oxychloride cement and a preparation method thereof. The magnesium oxychloride cement contains a magnesium ligand complex, the magnesium ligand complex contains Mg2+ and a cyclic ligand coordinated to the Mg2+, and the cyclic ligand contains at least two independent electron donating atoms selected from phosphorus and oxygen. The magnesium oxychloride cement is preferably prepared from the following raw materials in parts by mass: 300-440 parts of light calcined magnesium oxide,195-210 parts of magnesium chloride hexahydrate, 120-130 parts of water and 0.6-3.6 parts of phytic acid. The magnesium oxychloride cement has excellent water resistance and strength, and is wide inraw material source and easy for industrial application.
本发明属于无机胶凝材料技术领域，具体涉及一种氯氧镁水泥及其制备方法。所述氯氧镁水泥含有镁‑配位体络合物，所述镁‑配位体络合物包含Mg2+和配位于所述Mg2+的环状配体，所述环状配体含有至少2个独立的地选自磷和氧的供电子原子，优选由包括以下质量份的原料制备得到:轻烧氧化镁300～440份、六水合氯化镁195～210份、水120～130份、植酸0.6～3.6份。本发明提供的氯氧镁水泥具有优异的耐水性和强度，同时原料来源广，易于工业化应用。
