Summary of the invention
Primary and foremost purpose of the present invention is, overcome problems of the prior art, provide a kind of ocean wind-powered electricity generation with the rotten anti-cable insulation rubber that reverses of salt tolerant, production technique is simple, cost is lower, external diameter is little, in light weight, soft pliable is bent, be convenient to construction and installation, possess anti-ly reverse, sea water resistance salt air corrosion and the moist saturating machine of sea water resistance.
For solving above technical problem, the invention provides a kind of ocean wind-powered electricity generation with the rotten anti-cable insulation rubber that reverses of salt tolerant, the feed composition and the weight content of described electro-insulating rubber are as follows, terpolymer EP rubber Keltan 5508:8 part; Terpolymer EP rubber Dutral TER4044:12 part; Particle ethylene elastomer rubber EP-20:5 ~ 7 parts; Vulcanizing agent dicumyl peroxide: 0.5 ~ 0.7 part; Covulcanization agent triallylcyanurate: 0.3 ~ 0.5 part; Scorch retarder N, a N '-penylene bismaleimides: 0.2 ~ 0.4 part; Anti-aging agent 2,2,4-trimethylammonium-1,2-dihyaroquinoline polymer: 0.2 ~ 0.4 part; Anti-aging agent 2 mercapto benzimidazole: 0.2 ~ 0.4 part; Silane coupling agent γ-An Bingjisanyiyangjiguiwan: 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 tri-lead tetroxide: 0.8 ~ 1.2 part; Activator stearic acid: 0.5 ~ 1 part; Activator nano zine oxide: 1.5 ~ 2 parts; Softening agent Sunpar 2280 paraffin oils: 2 ~ 5 parts; Softening agent chlorinated paraffin-52: 0.5 ~ 1 part; Strengthening agent hydrated SiO 2: 1 ~ 3 part.
With respect to prior art, the present invention has obtained following beneficial effect: terpolymer EP rubber Keltan 5508 is mixing good with the expressing technique performance, the electrical insulation properties excellence, but cost height, terpolymer EP 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 particulate state 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(EPR) has good consistency, has intensity, the increase cable Surface Insulation smooth finish that reduces the epoxy glue mooney viscosity, strengthens rubber unvulcanizate, 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 resistance toheat that improves cross-linked rubber of antioxidant MB, strengthen the cable working temperature, improve current capacity, antioxidant MB has the copper conductor of inhibition solarization simultaneously.Because the direct coating conductor of insulation among the present invention, need avoid using the vulcanizing agent and the promotor 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 cupric 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 radical, seizes the hydrogen atom in the ethylene-propylene rubber(EPR), causes crosslinking reaction; But, cause the degraded of ethylene-propylene rubber(EPR) under acid and reducing substances influence because vulcanizing agent DCP produces ionic and decomposes, the crosslinked of ethylene-propylene rubber(EPR) and fracture are taken place simultaneously, reduced sulfuration efficient, the cross-linking density of cross-linked rubber is low, and tensile modulus and tensile strength are little; When list was with vulcanizing agent DCP simultaneously, its resolvent had stink.Thereby vulcanizing agent DCP vulcanizing agent TAC and usefulness have together been adopted, covulcanization agent TAC has two unsaturated active functional group groups, can be fast and the free radical reaction that decomposites of vulcanizing agent DCP, form constitutionally stable new radical and continue to participate in crosslinking reaction, improve the utilization ratio of vulcanizing agent DCP and the cross-linking efficiency of ethylene-propylene rubber(EPR), suppress the ethylene-propylene rubber(EPR) fracture and take place.The two shared acidity influence that has overcome the strengthening agent calcinated argil has guaranteed cross-linking efficiency.Peroxide vulcanizing agents such as scorch retarder HVA-2 and vulcanizing agent DCP are also used the curability that can significantly improve sizing material, improve thermotolerance, 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 aluminum oxide) not only to can be used as fire retardant, can play simultaneously the effect of weighting agent, do not need again extra absorb fillers, can reduce cost, it contains 3 water moleculess, begin to decompose at 250 ℃, discharge water molecules and absorb heat and reduced surrounding temperature, the water vapour that discharges has played the effect of combustable gas concentration in the dilution gas phase again, the aluminium sesquioxide that generates and the carbide combination of incendiary polymer surfaces, form protective membrane, cut off the intrusion of heat energy and oxygen, played fire retardation; Hydrated aluminum oxide has low smoke performance and reduces the effect that carbon monoxide takes place simultaneously, and the gas of release is water vapour, 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 degradation, 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 softening agent chlorinated paraffin-52 generation chemical reaction generate antimony chloride, boron chloride and zinc chloride, disengage combination water and produce glassy coverture, play coating effect and dilution effect, reach flame retardant effect, good dispersity.Strengthening 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(EPR), but hydrated SiO 2 have water-absorbent, 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-absorbent of weighting agent and strengthening agent, guarantee cross-linked rubber 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 wetting property of sizing material and weighting agent and strengthening agent, strengthen strengthening action; On the other hand in sulfidation, form rubber one filler key by unsaturated link(age), hydrated SiO 2 is changed to hydrophobicity by wetting ability, playing increases vulcanization rate, the tensile strength that improves cross-linked rubber and the water-resistant stability of electrical insulation capability, eliminates cross-linked rubber produces pore when the steam-pipe 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.Softening agent adopts Sunpar 2280 paraffin oils and chlorinated paraffin-52 and uses, Sunpar 2280 paraffin oil viscosity height, good with the ethylene-propylene rubber(EPR) mutual solubility, volatility is little, can reduce the elasticity of ethylene-propylene rubber(EPR), the harder shortcoming of rubber of improving its viscosity and adopting aluminium hydroxide to cause as flame retardant filler; The plasticity that the softening agent 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 flame retardant properties of sizing material.The adding of nano zine oxide can be accelerated vulcanization rate, improves state of vulcanization; Tri-lead tetroxide can improve acidproof, the water resistance of cross-linked rubber, and improves the heat aging property of rubber, be fit to boats and ships to the anti-water saturates of cable, contact water surrounding and heat-proof aging for a long time and increase current capacity and requirement in work-ing life.Stearic acid then possesses the effect of activator and softening softening agent simultaneously, promotes the active performance of nano zine oxide, makes the dispersiveness of nano zine oxide in sizing material better, more even; But tri-lead tetroxide 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 thermostability.Electro-insulating rubber tensile strength of the present invention is greater than 5.3N/mm2, elongation at break 〉=250%, and aging resistance 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-power 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.

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 resistance toheat that improves cross-linked rubber of antioxidant MB, strengthen the cable working temperature, improve current capacity, antioxidant MB has the copper conductor of inhibition solarization simultaneously.Because the direct coating conductor of insulation among the present invention, need avoid using the vulcanizing agent and the promotor 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 cupric 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 radical, seizes the hydrogen atom in the ethylene-propylene rubber(EPR), causes crosslinking reaction; But, cause the degraded of ethylene-propylene rubber(EPR) under acid and reducing substances influence because vulcanizing agent DCP produces ionic and decomposes, the crosslinked of ethylene-propylene rubber(EPR) and fracture are taken place simultaneously, reduced sulfuration efficient, the cross-linking density of cross-linked rubber is low, and tensile modulus and tensile strength are little; When list was with vulcanizing agent DCP simultaneously, its resolvent had stink.Thereby vulcanizing agent DCP vulcanizing agent TAC and usefulness have together been adopted, covulcanization agent TAC has two unsaturated active functional group groups, can be fast and the free radical reaction that decomposites of vulcanizing agent DCP, form constitutionally stable new radical and continue to participate in crosslinking reaction, improve the utilization ratio of vulcanizing agent DCP and the cross-linking efficiency of ethylene-propylene rubber(EPR), suppress the ethylene-propylene rubber(EPR) fracture and take place.The two shared acidity influence that has overcome the strengthening agent calcinated argil has guaranteed cross-linking efficiency.Peroxide vulcanizing agents such as scorch retarder HVA-2 and vulcanizing agent DCP are also used the curability that can significantly improve sizing material, improve thermotolerance, 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 aluminum oxide) not only to can be used as fire retardant, can play simultaneously the effect of weighting agent, do not need again extra absorb fillers, can reduce cost, it contains 3 water moleculess, begin to decompose at 250 ℃, discharge water molecules and absorb heat and reduced surrounding temperature, the water vapour that discharges has played the effect of combustable gas concentration in the dilution gas phase again, the aluminium sesquioxide that generates and the carbide combination of incendiary polymer surfaces, form protective membrane, cut off the intrusion of heat energy and oxygen, played fire retardation; Hydrated aluminum oxide has low smoke performance and reduces the effect that carbon monoxide takes place simultaneously, and the gas of release is water vapour, 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 degradation, 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 softening agent chlorinated paraffin-52 generation chemical reaction generate antimony chloride, boron chloride and zinc chloride, disengage combination water and produce glassy coverture, play coating effect and dilution effect, reach flame retardant effect, good dispersity.Strengthening 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(EPR), but hydrated SiO 2 have water-absorbent, 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-absorbent of weighting agent and strengthening agent, guarantee cross-linked rubber 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 wetting property of sizing material and weighting agent and strengthening agent, strengthen strengthening action; On the other hand in sulfidation, form rubber one filler key by unsaturated link(age), hydrated SiO 2 is changed to hydrophobicity by wetting ability, playing increases vulcanization rate, the tensile strength that improves cross-linked rubber and the water-resistant stability of electrical insulation capability, eliminates cross-linked rubber produces pore when the steam-pipe 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.Softening agent adopts Sunpar 2280 paraffin oils and chlorinated paraffin-52 and uses, Sunpar 2280 paraffin oil viscosity height, good with the ethylene-propylene rubber(EPR) mutual solubility, volatility is little, can reduce the elasticity of ethylene-propylene rubber(EPR), the harder shortcoming of rubber of improving its viscosity and adopting aluminium hydroxide to cause as flame retardant filler; The plasticity that the softening agent 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 flame retardant properties of sizing material.The adding of nano zine oxide can be accelerated vulcanization rate, improves state of vulcanization; Tri-lead tetroxide can improve acidproof, the water resistance of cross-linked rubber, and improves the heat aging property of rubber, be fit to boats and ships to the anti-water saturates of cable, contact water surrounding and heat-proof aging for a long time and increase current capacity and requirement in work-ing life.Stearic acid then possesses the effect of activator and softening softening agent simultaneously, promotes the active performance of nano zine oxide, makes the dispersiveness of nano zine oxide in sizing material better, more even; But tri-lead tetroxide 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 thermostability.Electro-insulating rubber tensile strength of the present invention is greater than 5.3N/mm2, elongation at break 〉=250%, and aging resistance 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-power 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.
