Abstract:
The intumescent flame retardant melamine pyrophosphate was prepared by melamine and pyrophosphoric acid in sol vent. The optimum conditions for preparation were determined as follows: temperature: 5~ 15 ℃ , time: 2.5 h, material mole ratio: 2. 1: 1, the mother solution could be recycled 3 times. The P content was analyzed by ammonium molybdophosphate ( AMP) precipitation method, the result was 14. 0%. The decomposition temperature was about 300℃ by the thermogravimetric analysis.
