As preferred version of the present invention, rotten anti-raw material components and the weight content that reverses rubber insulation of described salt tolerant is as follows, ethylene propylene diene rubber Keltan 5508:8 part; Ethylene propylene diene rubber Dutral TER4044:12 part; Particle ethylene elastomer rubber EP-20:5 ~ 7 parts; Vulcanizing agent cumyl peroxide: 0.5 ~ 0.7 part; Co-vulcanization agent triallylcyanurate: 0.3 ~ 0.5 part; Antiscorching agent N, a N '-penylene bismaleimides: 0.2 ~ 0.4 part; Age resistor 2,2,4-trimethyl-1,2-dihyaroquinoline condensate: 0.2 ~ 0.4 part; Age resistor 2 mercapto benzimidazole: 0.2 ~ 0.4 part; Silane coupler gamma-aminopropyl-triethoxy-silane: 0.2 ~ 0.4 part; Fire retardant hydration zinc borate: 2.1 ~ 2.5 parts; Fire retardant antimonous oxide: 1 ~ 1.5 part; Flame retardant filler aluminium hydroxide: 25 ~ 40 parts; Activator lead orthoplumbate: 0.8 ~ 1.2 part; Activator stearic acid: 0.5 ~ 1 part; Activator nano zine oxide: 1.5 ~ 2 parts; Plasticizer Sunpar 2280 paraffin oils: 2 ~ 5 parts; Plasticizer chlorinated paraffin-52: 0.5 ~ 1 part; Reinforcing agent hydrated SiO 2: 1 ~ 3 part.Ethylene propylene diene rubber Keltan 5508 is mixing good with the expressing technique performance, electrical insulation properties excellence, but cost height, and ethylene propylene diene rubber Dutral TER4044 then has excellent expressing technique performance, and cost is low, and proportion is little; Particle ethylene elastomer rubber EP-20 is the copolymer elastomer graininess rubber of a kind of modulated ethene and alpha-olefin, its flowability is good, density only is 0.903g/cm3, itself and other ethylene-propylene rubber has good compatibility, has intensity, the increase cable insulating surface fineness that reduces the epoxy glue Mooney viscosity, strengthens elastomeric compound, the characteristics of improving Extrusion Flow, raising extruded velocity; The shared electrical insulation properties that had both guaranteed electro-insulating rubber of three has been guaranteed the manufacturability of rubber, apparent, extruded velocity and cost economy simultaneously.Adopt anti-aging agent RD and the shared heat resistance that improves vulcanizate of antioxidant MB, strengthen the cable working temperature, improve ampacity, antioxidant MB has the copper conductor of inhibition aging action simultaneously.Because the direct coating conductor of insulation among the present invention, need avoid using the vulcanizing agent and the promoter of sulphur and sulfur-bearing, because adopt the vulcanized rubber heat aging property of this type of vulcanizing agent very poor, and copper is corrosive, produce the black copper sulfide on the copper surface, increase the resistance of copper conductor, reduce the current delivery ability.Adopt vulcanizing agent DCP to vulcanize the bright and clean and purity that can keep conductor for a long time as main vulcanizing agent, vulcanizing agent DCP decomposes produces free radical, seizes the hydrogen atom in the ethylene-propylene rubber, causes cross-linking reaction; But, cause the degraded of ethylene-propylene rubber under acid and reducing substances influence because vulcanizing agent DCP produces ionic and decomposes, the crosslinked of ethylene-propylene rubber and fracture are taken place simultaneously, reduced sulfuration efficient, the crosslink density of vulcanizate is low, and stretching strength and tensile strength are little; When list was with vulcanizing agent DCP simultaneously, its analyte had stink.Thereby vulcanizing agent DCP vulcanizing agent TAC and usefulness have together been adopted, co-vulcanization agent TAC has two unsaturated active functional group groups, can be fast and the radical reaction that decomposites of vulcanizing agent DCP, form constitutionally stable new free radical and continue to participate in cross-linking reaction, improve the utilance of vulcanizing agent DCP and the cross-linking efficiency of ethylene-propylene rubber, suppress the ethylene-propylene rubber fracture and take place.The two shared acidity influence that has overcome the reinforcing agent calcinated argil has guaranteed cross-linking efficiency.Peroxide vulcanizing agents such as antiscorching agent HVA-2 and vulcanizing agent DCP are also used the curability that can significantly improve sizing material, improve thermal endurance, reduce sizing material compression set rate, reduce amount of peroxide, prevent the incipient scorch of sizing material in the course of processing, help avoid the difficult problem that copper conductor pollutes blackout simultaneously.Adopt aluminium hydroxide (hydrated alumina) not only to can be used as fire retardant, can play simultaneously the effect of filler, do not need additionally to add again filler, can reduce cost, it contains 3 hydrones, begin to decompose at 250 ℃, discharge hydrone and absorb heat and reduced environment temperature, the steam that discharges has played the effect of combustable gas concentration in the dilution gas phase again, the carbide combination of the alundum (Al that generates and the polymer surfaces of burning, form diaphragm, cut off the intrusion of heat energy and oxygen, played fire retardation; Hydrated alumina has low smoke performance and reduces the effect that carbon monoxide takes place simultaneously, and the gas of release is steam, fully to biological nontoxic, to hardware non-corrosiveness, environment-protecting clean.But aluminium hydroxide uses the very few flame retardant effect that is difficult to reach, and uses and too much can cause sizing material expressing technique decreased performance, and sizing material hardens, and can feed the glue difficulty when extruding, and the insulation outward appearance is coarse.Adopt aluminium hydroxide and antimonous oxide and hydration zinc borate shared, during burning and plasticizer chlorinated paraffin-52 generation chemical reaction generate antimony chloride, boron chloride and zinc chloride, disengage in conjunction with water and produce glassy covering, play blanketing effect and dilution effect, reach flame retardant effect, good dispersion.Reinforcing agent adopts hydrated SiO 2 strengthening action excellence, can effectively increase the physical and mechanical properties of rubber, improve the viscosity and the processing characteristics of ethylene-propylene rubber, but hydrated SiO 2 have water absorption, the immersion electric property is relatively poor, needs to carry out surface treatment by coupling agent and overcomes drawback.Silane resin acceptor kh-550 can effectively improve the water absorption of filler and reinforcing agent, guarantee vulcanizate at boats and ships electrical insulation capability stable under the moist or immersion environment, its one side and the spontaneous coupling of hydrated SiO 2, significantly reduce its granularity, make it to be easier to fill evenly, improve the wettability of sizing material and filler and reinforcing agent, strengthen strengthening action; On the other hand in sulfidation, form rubber one filler key by unsaturated bond, hydrated SiO 2 is changed to hydrophobicity by hydrophily, playing increases curingprocess rate, the tensile strength that improves vulcanizate and the water-resistant stability of electrical insulation capability, eliminates vulcanizate produces pore when the jet chimney continuous high temperature vulcanizes effect.And silane resin acceptor kh-550 proportion is little, and 0.94g/cm3 is only arranged, and can help alleviating the weight of cable.Plasticizer adopts Sunpar 2280 paraffin oils and chlorinated paraffin-52 and uses, Sunpar 2280 paraffin oil viscosity height, good with the ethylene-propylene rubber intersolubility, volatility is little, can reduce the elasticity of ethylene-propylene rubber, the harder shortcoming of rubber of improving its viscosity and adopting aluminium hydroxide to cause as flame retardant filler; The plasticity that the plasticizer chlorinated paraffin-52 can be promoted sizing material is on the one hand improved production and processing technology, on the other hand with fire retardant antimonous oxide and hydration zinc borate reaction, realizes the fire resistance of sizing material.The adding of nano zine oxide can be accelerated curingprocess rate, improves state of cure (vulcanization); Lead orthoplumbate can improve acidproof, the water resistance of vulcanizate, and improves the heat aging property of rubber, be fit to boats and ships to the anti-water saturates of cable, contact water environment and heat-proof aging for a long time and increase ampacity and requirement in useful life.Stearic acid then possesses the effect of activator and softening plasticizer simultaneously, promotes the performance of nano zine oxide activity, makes the dispersiveness of nano zine oxide in sizing material better, more even; But lead orthoplumbate easily makes rubber produce the getting up early sulfuration, and the adding of stearic acid and nano zine oxide then can reduce the incipient scorch tendency of sizing material, increases thermal stability.Electro-insulating rubber tensile strength of the present invention is greater than 5.3N/mm2, elongation at break 〉=250%, and ageing properties is superior, good insulation preformance; The ocean wind-powered electricity generation that electro-insulating rubber of the present invention is made is suitable with the prior art cable with the rotten anti-double shield telecommunication cable manufacturing cost of reversing of salt tolerant, but this cable has sea water resistance salt air corrosion performance, sea water resistance moisture saturating machine and anti-twisting property, and common cable does not then possess these performances.
