Abstract

The invention discloses a magnetic rubber material. The magnetic rubber material is characterized by comprising the following components in parts by weight: 60-80 parts of standard rubber, 25-35 parts of chloroprene rubber, 20-30 parts of carbon black, 15-25 parts of dibutyl ester, 3-7 parts of zinc oxide, 1-5 parts of magnesium oxide, 40-50 parts of nickel zinc ferrite, 1.5-2.5 parts of stearic acid, 0.3-0.7 part of accelerant M, 0.5-1.5 parts of accelerant DM, 0.3-0.7 part of accelerant NA, 0.03-0.07 part of accelerant TT, 0.4-0.8 part of anti-aging agent 4010, 0.4-0.8 part of anti-aging agent RD and 1.4-1.8 parts of sulphur. The magnetic rubber material has the advantages that mixing and vulcanization steps are adopted, so that plasticity of the magnetic rubber material can be effectively improved, and the plasticity of the magnetic rubber material is more than 0.55; the magnetic rubber material is sulphurized after being magnetized, so that magnetic property of the magnetic rubber material can be permanently maintained.
