The invention discloses a
graphene rubber macromolecular
flame-retardant composite foaming material and a preparation method thereof. The
graphene rubber macromolecular
flame-retardant composite foaming material comprises the following raw materials in parts by weight: 50-60 parts of
natural rubber, 13-17 parts of butadiene rubber, 4-6 parts of
ethylene propylene
diene monomer, 4-6 parts of whitecarbon black, 14-17 parts of a
flame retardant, 1.8-2.4 parts of
graphene, 4-6 parts of a nano medium, 2-3 parts of
zinc oxide, 2.5-4 parts of a heat stabilizer, 2-2.4 parts of a cross-linking agent,3-4 parts of a flow aid and 2-2.4 parts of a
foaming agent, wherein the flame retardant is a mixture of
zinc diethylphosphinate and
triphenyl phosphate. The flame-retardant test of the graphene rubbermacromolecular flame-retardant composite foaming material reaches a UL-94V0 level, and the
oxygen index of the graphene rubber macromolecular flame-retardant composite foaming material is far higherthan that of a common
natural rubber foam material; the density of the graphene rubber macromolecular flame-retardant composite foaming material is lower than that of a common
natural rubber foaming material, and the graphene rubber macromolecular flame-retardant composite foaming material is ultra-light; and moreover, the tensile strength of the graphene rubber macromolecular flame-retardant composite foaming material is greatly superior to that of a common natural rubber foaming material, the
mechanical property is good, and the ultra-light property and the excellent
mechanical property arewell considered.
