Magnesium phosphate cement as well as preparation method and application thereof
The invention relates to magnesium phosphate cement as well as a preparation method thereof. The magnesium phosphate cement at least comprises the following components in parts by weight: 100-400 parts of sintered magnesia, 100 parts of phosphate and 5-80 parts of a compound retarder, wherein the sintered magnesia is a calcined product of a salt lake-based lithium by-product magnesium oxide; and the compound retarder comprises a mixture of at least two of glucose, sucrose and chloride, and can also comprise citric acid. The preparation method of the magnesium phosphate cement comprises the following steps: mixing the sintered magnesia and the phosphate with the compound retarder, and carrying out ball-milling to obtain the magnesium phosphate cement. The compound retarder can be applied to a bone repair surgery. According to the magnesium phosphate cement disclosed by the invention, the hydration reaction rate and the hydration temperature are reduced; meanwhile, the strength of the magnesium phosphate cement meets the requirements; the operation is simple; and the cost is relatively low.
