METAL ION MODIFIED MELAMINE POLYPHOSPHATE COMPOUND, PROCESS FOR ITS PREPARATION AND USE OF IT

This invention concerns a melamine polyphosphate salt compound modified by a metal ion of the following formula. The formula is as shown in formula (I): with M: metal ion, Z + is the oxidation state of M, n is average degree of polymerization of polyphosphoricacid , n 2. This invention of a metal ion modified melamine polyphosphate has stable heat resistance, excellent flame retardancy and can be easily incorporated into various plastics. This invention application also reveals the process method which includes following steps: (1) add polyphosphoric acid slowly into melamine while stirring and then increase the temperature for reaction and made the compound of melamine polyphosphate. (2) then add metal ion into the melamine polyphosphate compound. Stir and then increase temperature for reaction and made the final product. It's a facile process, stable and controllable, with a mild reaction temperature. Other advantages are low energy consumption, less environmental pollution and no corrosion of the reactor tubes.
