Progress of Research Trinity-intumescent Flame Retardant System

Trinity-intumescent flame retardant plays an important role in the synthesis of halogen-free flame retardant. Trifunctional(source of acid,char-forming agent and blowing agent)was widely attracted more attention due to its high thermal stability、weatherability and better flame retardant、low smoke、low toxicity、low addition. Research of the recently of trinity-intumescent flame system was reviewed.
