Preparation method of ethylene propylene diene monomer (EPDM)

The invention discloses ethylene propylene diene monomer (EPDM), belonging to the field of rubber materials. The EPDM is prepared from the following components in parts by mass fraction: 100-140 parts of EPDM, 10-30 parts of an ethylene-propylene methylene copolymer, 6-8 parts of zinc oxide, 1-2 parts of stearic acid, 1-3.5 parts of an anti-aging agent 4010 NA, 1-2 parts of an anti-aging agent RD, 20-40 parts of N-330 carbon black, 30-60 parts of N-774, 40-80 parts of a casting slag XJ01 reinforcing agent, 10-15 parts of glass fiber powder, 1-5 parts of a silane coupling agent KH560, 20-40 parts of paraffin oil, 1-2.5 parts of an accelerant BZ, 1-2.5 parts of an accelerant CZ, 1-2 parts of an accelerant TETD, 6-12 parts of a cross-linking agent DCP and 0.5-1 part of sulphur. The EPDM provided by the invention is excellent in appearance and moderate in hardness, and has high wear resistance and high tensile strength under the condition of high temperature resistance. 本发明公开了种三元乙丙橡胶，属于橡胶材料领域，其组分和质量分数为：三元乙丙橡胶100～
