The Study on Application of N-P Intumescent Flame Retardant Agent in Waterborne Polyurethane
Phosphorylation for the first generation product of hyperbranched polymer with terminal hydroxyl (HPAEl) was carried out to synthesize a type of P-N intumescent flame retardant (HPAEl-P),with phosphorus pentoxide and phosphoric acid as phosphorylating agent.HPAEl-P was used in waterborne polyurethane MWU-T-502B-30,and then they were tested the properties of the emulsion,such as the stability,LOI,smoke density and vertical combustion performance.The results showed that the compatibility of this flame retardant agent and waterborne polyurethane MWU-T-502B-30 was very good,and this flame retardant agent could effectively improve the polyurethane flame retardant property.
