Study on Synthesis and Application of Methylmethoxyphosphonate Aluminum

Article Preview

Abstract:

A novel flame retardant of methylmethoxyphosphonate aluminium (MMPA) was synthesized via the reaction of anhydrous aluminum chloride and dimethyl methylphosphonate (DMMP). The effects of introducing order of reactants, reaction time and washing agents were investigated to get pure target compound with higher yields.Application experiments indicates that MMPA is an effective flame retardant for PBT, especially when it is used in intumescent flame retardant(IFR) systems. When the composition of IFR is 20% wt., the limited oxygen index(LOI) value of the IFR-PBT is 30 and can pass the UL94 V-0 test.
