Research Progress of Triazine- based Charring Agents

This paper overviewed the raw materials, synthetic technology and flame retardant effect of triazine based charring agents in terms of their molecular structures including small molecules, linear macromolecules and hyperbranched macromolecules. Charring agents prepared by using cyanuric chloride, melamine, cyanuric acid and its derivatives as raw materials were emphatically introduced. Moreover, advantages and disadvantages of different types of triazine based charring agents were analyzed, and their development prospect was discussed.
