Thermoplastic resin-coated ammonium polyphosphate comprises a core material which comprises ammonium polyphosphate and a thermosetting resin, a melamine monomer or a surface-treating agent; and a coating layer of a thermoplastic resin which covers the core material. The thermoplastic resin-coated ammonium polyphosphate is excellent in water resistance, resistance to acids, resistance to alkalis, resistance to ions and resistance to organic solvents and if it is incorporated into a resin composition as a component of a flame retardant used therein and the composition is formed into a molded article, the resulting article does not show any marked reduction of its mechanical strength.
涂有热塑性树脂的聚磷酸铵包括芯材(由聚磷酸铵和热固性树脂、三聚氰胺单体或表面处理剂组成)和覆盖芯材的热塑性树脂涂层。涂有热塑性树脂的聚磷酸铵具有优异的耐水性、耐酸性、耐碱性、耐离子性和耐有机溶剂性,如果将其作为其中所用阻燃剂的成分加入树脂组合物中,并将组合物制成模塑制品,则所得制品的机械强度不会明显降低。
