Abstract

The invention discloses a flame-retardant and antistatic epdm (ethylene-propylene-diene monomer) material. The flame-retardant and antistatic epdm material is prepared from EPDM rubber, nitrile rubber, polyethylene glycol terephthalate, silicon dioxide, graphene, nanometer titania, nano-particles of polyacenic semiconductor material, zinc oxide, magnesium oxide, stearic acid, dicumyl peroxide, sulphur, trimethylolpropane triacrylate, acrylonitrile grafted epdm, an accelerant, an anti-aging agent, a flame retardant, octadecyl methyl dihydroxyethyl ammonium bromide and polyoxyethylene stearate;the flame retardant is a mixture of aluminum diethyl phosphonate, melamine pyrophosphate, aluminum hydroxide, carbon microspheres and ammonium polyphosphate. The flame-retardant and antistatic epdm material is high in strength, excellent in heat resistant and flame retardant property and good in antistatic property.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a flame-retardant and antistatic EPDM material. Background technique [0002] EPDM rubber is a copolymer produced by the polymerization of ethylene, propylene and non-conjugated diene. It has the advantages of low density, high filling, aging resistance, corrosion resistance and good elasticity. It has been used in waterproof materials , automotive parts, wire and cable sheaths, heat-resistant hoses, and automotive seals. But like most hydrocarbon polymers, EPDM rubber is also very flammable, and the oxygen index of pure rubber is only about 19, which limits its use. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a flame-retardant and antistatic EPDM material, which has high strength, excellent heat resistance and flame retardancy, and good antistatic performance. [0004] A flame-retarda...
