Problems solved by technology

[0002] At present, the power cables for slag tank trucks mostly use ordinary rubber sheaths. The mechanical properties and aging performance of ordinary rubber sheaths are poor, and they are not resistant to oil. After being immersed in oil, the tensile strength and elongation at break drop greatly, which makes the service life of the cables short. , prone to cracking

Abstract

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.
