The invention provides a siloxane-modified cyclotriphosphazene halogen-free flame retardant, a preparation method and application thereof. The siloxane-modified cyclotriphosphazene halogen-free flame retardant has the structure shown in Formula I. formula. The siloxane-modified cyclotriphosphazene halogen-free flame retardant of the present invention constructs three structures of siloxane, arylphosphine and cyclotriphosphazene in one molecular formula, which combines the advantages of the three structures and improves The compatibility between the flame retardant and the resin, the flame retardant efficiency is high, the carbon forming property is good, and the flame retardant performance and stability of the cured resin can be greatly improved. |
