Abstract
The invention discloses a shielding longitudinal watertight degaussing cable and a production method thereof for ships. A tinned copper wire is impregnated with a sealant and then twisted into a twisted copper conductor which is impregnated with a conductor sealant layer on the periphery, an electro-insulating rubber layer is extruded on the periphery of the conductor sealant layer to form insulation core wires, chloroprene rubber filling bars are filled into gaps between the insulation core wires, and a plurality of insulation core wires are twisted wholly into a cable core. A cable core inner sealant layer, an inner jacket rubber layer, an armor shielding layer and an outer jacket rubber layer are sequentially arranged on the periphery of the cable core. A single wire of the cable conductor is impregnated with the sealant, the twisted copper conductor is impregnated with the conductor sealant layer on the periphery, the cable core inner sealant layer is extruded on the periphery of the cable core to form multiple sealing, the chloroprene rubber filling bars swell during follow-up vulcanization and can fill in the gaps inside the cable core completely, and tangency between the insulation core wires can be avoided, so that the sealant can permeate to the inside of the cable core to guarantee the watertight effect when the cable core inner sealant layer is extruded.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of naval vessel shield type direction waterproof degaussing cable; The invention still further relates to a kind of naval vessel manufacture method of shield type direction waterproof degaussing cable.
Background technology
The naval vessel especially under water the naval vessel in the navigation process because of stealthy importance, to prevent that especially magnetic mine from attacking, need often carry out the hull demagnetization for this reason.Fixedly demagnetization is carried out demagnetization at degaussing stations and is got final product, but just need to carry out demagnetization by the outer eraser system of installing of self ship side for the induced field that the naval vessel under water that is in for a long time in the navigation process produces.But because under water particularity and the complexity of ship navigation environment, common degaussing cable can't satisfy simultaneously that ship side is outer installs the specification requirement that required longitudinal sealing and demagnetization performance possess simultaneously.
In the electro-insulating rubber industry, ethylene propylene diene rubber K21, the ethylene propylene diene rubber 4045M of arriving commonly used also uses various vulcanizing agents, age resistor, and wherein the vulcanizing agent cumyl peroxide claims again vulcanizing agent DCP, molecular formula C18H22O2; The vulcanization accelerator iso-cyanuric acid triallyl ester claims again vulcanization accelerator TAIC, and the age resistor 2 mercapto benzimidazole claims again antioxidant MB, age resistor 2,2, and 4-trimethyl-1,2-dihyaroquinoline condensate claims again anti-aging agent RD.
In the jacket rubber industry, commonly used to chlorosulfonated polyethylene rubber H40; Also use various vulcanizing agents, activating agent, age resistor, plasticizer, fire retardant and filler.The vulcanization accelerator dibenzothiazyl disulfide claims again vulcanizing agent DM, and molecular formula is C14H8N2S4; Vulcanization accelerator six sulfuration di-penta methylene thiurams claim again accelerator D PTT; The age resistor nickel dibutyl dithiocarbamate claims again antioxidant NBC, and molecular formula is C18H36N2S4Ni, and molecular weight is 467.51; Age resistor 4,4 '-two (alpha, alpha-dimethylbenzyl) diphenylamines claims again antioxidant HS-911, released in 2005 by Huangyan, Zhejiang China star laboratory; The plasticizer phthalic acid dioctyl ester claims again plasticizer DOP.
White carbon is divided into precipitated silica and fume colloidal silica by production method.Be the gluey nano particle of the amorphous cotton-shaped translucent solid of white under the white carbon normality, primary particle diameter is between 7～80nm, and specific area is generally greater than 100 ㎡/g.By halide (mainly being silicon tetrachloride and methyl trichlorosilane) the nanoscale white powder that pyrohydrolysis generates in oxyhydrogen flame of silicon, mainly as reinforced filling and multifunction additive.
Publication number is that the patent of invention of CN 102408636A discloses a kind of degaussing cable insulating material and preparation method thereof, it adopts ethylene-propylene rubber TER4044 and EBM4050 as the rubber matrix, and take TER4044 as main, as plasticizer, have good electric insulation and mechanical strength with paraffin wax fully refined, paraffin oil and microcrystalline wax.Ethylene-propylene rubber is fire-retardant thinks that energy is relatively poor, and oxygen index is usually less than 26, and fire resistance is bad.
Publication number is that the patent of invention of CN 102417639A discloses corrosion-resistant sheath material of a kind of degaussing cable waterproof and preparation method thereof, has adopted 100 parts of neoprenes, vulcanizing agent 5-20 part, vulcanization accelerator 0.5-5 part, vulcanization aid 0.5-5 part, filler 50-120 part, reinforcing agent 15-10 part, age resistor 1-5 part, plasticizer 5-15 part, fire retardant 5-20 part, coupling agent 1-5 part, processing aid 2-6 part.This sheath material adopts neoprene, the sea water corrosion resistant of neoprene is well below chlorosulfonated polyethylene, this sheath material is only realized immersing seawater and is born withstand voltage (7kV after 14 days, 5min) do not puncture, on water resistance radially, can only bear 0.5MPa air pressure, proof voltage (7kV, 5min) does not puncture.
