Abstract

The invention relates to a composite flame retardant and a preparation method. The composite flame retardant is formed by coating graphene with aluminum hydroxide. Aluminum hydroxide is uniformly dispersed to the surface of graphene so as to form an aluminum hydroxide-graphene composite flame retardant with a relatively good coating layer, aluminum hydroxide is decomposed into water and aluminum oxide when a material is combusted, aluminum oxide generated by the decomposition of aluminum hydroxide uniformly covers the surface of graphene so as to form a compact structure, and aluminum oxide and a carbon layer cover the surface of a polyolefin material to generate synergetic flame retardance effect so as to realize thermal insulation and oxygen isolation, so that the flame retardance of thepolyolefin material is improved.
