The invention discloses a
slag pot carrier cable sheath material and a manufacturing method thereof. The
slag pot carrier cable sheath material comprises 23 parts of
chloroprene rubber CR3221, 1.2 to 1.5 parts of
zinc oxide, 1 to 1.5 parts of
magnesium oxide, 0.1 to 0.3 parts of
tetramethylthiuram disulfide (TMTD), 0.2 to 0.3 parts of
ethylene thiourea (ETU), 1.0 to 1.3 parts of
dioctyl sebacate (DOS), 0.45 to 0.6 parts of dioctyl
phthalate (DOP), 0.1 to 0.15 parts of
stearic acid (SA), 1.2 to 1.4 parts of
microcrystalline paraffin, 0.9 to 1.2 parts of iso-octyl decyl
adipate (ODA), 0.1 to 0.15 parts of N-(p-
toluene-sulphonylamido-N'-
phenylene diamine) (TPPD), 0.2 to 0.4 parts of 4,4-bis(alpha,alpha-dimethylbenzyl)
diphenylamine (HS)-911, 5 to 8 parts of
carbon black, 4.5 to 6 parts of semi-reinforced
carbon black, 0.5 to 0.7 parts of
vaseline, 8 to 10 parts of calcining potter's clay and 3 to 4 parts of
calcium carbonate. The manufacturing method comprises the following steps of 1, mixing the
chloroprene rubber CR3221 for 5 to 7 minutes, 2, adding the
magnesium oxide as an
active agent, the
zinc oxide as an
active agent, the
microcrystalline paraffin, the SA, the
calcium carbonate, the DOP, the
carbon black, the DOS, the semi-reinforced carbon black and the
vaseline into the mixture obtained by the step 1 to carry out mix for 9 to 11 minutes, 3, adding the calcining potter's clay, the ODA, the TPPD, the HS-911, the TMTD and the ETU into the mixture obtained by the step 2 to carry out mixing, wherein the TMTD and the ETU are added at the last 90 seconds, and 4, moving the mixture obtained by the step 3 to an open mill to carry out tabletting, turning eight triangular cornerites, and
cutting into tablets. A cable sheath prepared from the
slag pot carrier cable sheath material has the advantages of excellent mechanical properties, high tensile strength,
high fracture elongation,
aging resistance and oil resistance.
