Problems solved by technology

[0002] At present, the signal flexible cables for underwater buckets of dredgers 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 immersion in oil, the tensile strength and elongation at break drop greatly. Make the service life of the cable short and prone to cracking

Abstract

The invention discloses a signal flexible cable sheath material for an underwater dredging bucket of a dredger and a production method thereof. The signal flexible cable sheath material comprises the following components in parts by weight: 20 parts of chloroprene rubber T-type CR rubber, 1-1.5 parts of zinc oxide, 0.5-1.0 part of magnesium oxide, 0.05-1.0 part of NA (Natrium)-22, 0.1-0.5 part ofTMTD (Tetramethylthiuram Disulfide), 0.1-0.5 part of DM (Dibenzothiazyl Disulfide), 0.5-1.0 part of RD (poly(1,2-dihydro-2,2,4-trimethyl-quinoline)), 0.5-1.0 part of white wax, 0.5-1.0 part of stearic acid, 0.5-1.0 part of vaseline, 2.0-5.0 parts of carbon black, 8.0-15 parts of semireinforcing carbon black, 0.1-0.5 part of 4010NA, 10-15 parts of calcium carbonate, 1.0-2.5 parts of antimony trioxide and 0.5-1.0 part of talcum powder. The production method comprises the following steps of: firstly mixing the chloroprene rubber T-type CR rubber in an internal mixer for 8-10 min; then adding magnesium oxide and the like to mix for 8-10 min; filtering rubber and then adding zinc oxide and NA-22 to continuously mix for 4-7 min; adding TMTD and DM at the last 45-60 s; further rolling on an openmill; punching 6-8 triangular packages; overturning uniformly and discharging a tablet; and cooling completely for later use. A cable sheath produced by the cable sheath material has excellent mechanical property, high tensile strength, large elongation at break, ageing resistance and oil resistance.

Description

technical field [0001] The invention relates to a sheathing material for cables, in particular to a signal flexible cable sheathing material for an underwater bucket of a dredger. Background technique [0002] At present, the signal flexible cables for underwater buckets of dredgers 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 immersion in oil, the tensile strength and elongation at break drop greatly. The service life of the cable is short and it is prone to cracking. Contents of the invention [0003] The primary purpose of the present invention is to provide a signal flexible cable sheathing material for an underwater dredger bucket with good mechanical performance and aging resistance. [0004] In order to achieve the above object, the signal flexible cable sheathing material for the dredger underwater bucket provided by the present invention has the fo...
