The flame retardant is a cross-linked product of amino cyclotriphosphazene which is hexa (2-aminoethoxy) cyclotriphosphazene after polycondensation for 3 hours under an acidic condition. The amino-containing cyclotriphosphazene is a pre-crosslinked product of hexa (2-aminoethoxy) cyclotriphosphazene, has larger molecular weight, and a small amount of peripheral amino groups can also be used as a curing agent to be crosslinked with epoxy resin and epoxy organic silicon resin in preparation, and the epoxy cyclotriphosphazene is matched with polyamide to realize better crosslinking effect.
