NOVELTY - The utility model claims a multi-wall fire retardant microcapsule based on graphene, comprising flame retardant core and multi-layer wall material of the flame retardant core is set on the outer surface of said multi-layer wall material is composed of an organic material layer and a graphene material layers are arranged alternately, and the innermost layer and the outermost layer is an organic material layer. The utility model based on multi-wall fire retardant microcapsule of the graphene, the wall material is organic material and the graphene material layer alternately formed, has strong barrier preventing flame absorption, graphene material by organic interlayer; the mechanical property is improved obviously; multi-layer structure design, in the melting process still keeps good compatibility with the substrate, graphene as barrier and flame retardant promoter, can obviously improve the flame retardant effect, reduces the usage amount of flame retardant and has good popularization value.
