Hyperbranched polyphosphazene flame retardant charring agent and preparing method thereof
An efficient hyperbranched polyphosphazene flame retardant charring agent is prepared by reacting hexachlorocyclotriphosphazene with a binary compound containing two active groups. The charring agent has characteristics of good foaming charring performance, excellent flame retardant effects and good processing performance, and can be widely used in plastics, rubber, coating, adhesives, and other polymer materials. A preparing method adopts a one-pot method, and has characteristics of continuous reaction process, short reaction time and high production efficiency. By controlling the mole ratio of the hexachlorocyclotriphosphazene to the binary compound, no end-capping agent is added in the reaction process. When compared with the addition of end-capping agents in synthesis processes in triazine type charring agent patents, the synthetic process of the charring agent is simplified.
