Abstract

Polyphenylene oxide and the intumescent flame retardant were used in combination to achieve the fire-retardancy of polystyrene. The IFR system is mainly composed of ammonium polyphosphate, pentaerythritol and melamine. To solve the problems existed in the ternary IFR system, such as hydrophilicity and heterogeneity in particle size and mixing, IFR powders were surface modified by silane coupling agent KH-550 via wet ball milling. The results showed that the combination of PPO and IFR could effectively enhance the thermal stability and improve the flame-retardant performance of composites, with the synergistic effect between them.
