Abstract

The present invention provides a siloxane-modified cyclotriphosphazene halogen-free flame retardant, and a preparation method and a use thereof. The siloxane-modified cyclotriphosphazene halogen-free flame retardant has the structural formula as shown in Formula I. In the siloxane-modified cyclotriphosphazene halogen-free flame retardant of the present invention, three kinds of structures of siloxane, aryl phosphorus oxygen compound and cyclotriphosphazene are built in one molecular formula, which combines the advantages of three structures, improves the compatibility between the flame retardant and resins, has a high flame retardant efficiency and a better char formation and can greatly increase the flame retardancy and stability of resin cured products.
