    • The present invention relates to a method for preparing amino phosphate flame retardants. Melamine and phosphoric acid substances are used as a starting material, AND then the starting material reacts in the absence of solvents at a temperature ranging from 40 to 200° C. to obtain powdery amino phosphate compounds used as flame retardants. Since the reaction free of solvents is carried out under a condition of lower temperature, the powdery amino phosphate compounds can be obtained without drying steps. Therefore, not only the contaminations caused by solvent volatilization can be avoided, but also the process of preparing the product is simplified and the cost of the product is reduced.
    • 本发明涉及一种制备氨基磷酸酯阻燃剂的方法。 使用三聚氰胺和磷酸物质作为原料,然后起始物质在不存在溶剂的情况下在40〜200℃的温度下反应,得到用作阻燃剂的粉末状氨基磷酸酯化合物。 由于没有溶剂的反应在较低温度的条件下进行,所以可以在没有干燥步骤的情况下获得粉状氨基磷酸酯化合物。 因此,不仅可以避免由溶剂挥发引起的污染,而且简化了产品的制备过程,降低了产品的成本。
