摘要：

Flame retardation and water-resistance still remained concerned for the intumescent flame retardant. In this work, a flame retardant, amino trimethylene phosphonic melamine salt (ATMPMEL), was synthesized via the reaction of amino trimethylene phosphonic acid (ATMP) and melamine. The products were characterized by FT-IR, XRD, element analysis, and water solubility. The results indicate that ATMPMEL exhibits an excellent water-resistant property while the mole ratio of ATMP to melamine in this reaction is nearly 1:2. The flame retardant performance of PP composites was investigated by limiting oxygen index (LOI), UL-94 vertical test, cone calorimeter test(CCT)and thermogravimetry analysis (TGA). The results confirm that both the ATMPMEL/ pentaerythritol (PER) system and ATMPMEL/ammonium polyphosphate (APP) /PER system could effectively improve the thermostability of PP and reduce the heat release rate and smoke production rate, indicating a remarkable flame retardancy. SEM images prove the char residue of PP/ATMPMEL/APP/PER system is more continuous and compact. Furthermore, the prepared flame retardant PP composites exhibit rather good water resistant and their LOI values are slightly decreased after being soaked in water at 25 ℃ for 168 h. © 2020, Editorial Board of Polymer Materials Science & Engineering.
