Background technology
Along with country strengthens the attention developed ocean energy resources, large quantities of new ships is built, because ship's navigation mostly is marine site, ocean, goes to sea of long duration, needs the own wt alleviating naval vessel for this reason, increases the useful load on naval vessel.Cable is as naval vessel electric energy transfer device, and the load of its weight on boats and ships has very large impact.And the weight of cable and cross-sectional area of conductor amass relevant, cross-sectional area of conductor is long-pending then mainly to be determined by current capacity, and the factor affecting current capacity is except conductor material and sectional area, also has insulation used, sheath material and the construction of cable etc.Because shipboard cable conductor is twisted copper conductors, therefore shipboard cable current capacity is mainly determined by insulation, sheath material and the construction of cable.
Prior art is mainly passed through to improve the operating temperature ratings of insulation and sheath material thus the current capacity of raising cable, but the less surface temperature of cable that makes of the thermal resistance coefficient ren due to current material is very high, 110 DEG C can be reached, and cable dispels the heat not smooth in narrow and small boats and ships space, envrionment temperature is caused to raise, more can reduce again the current capacity of cable, and affect the safety of other facilities around, cause vicious cycle.The thermal resistance coefficient ren of existing rubber insulation material is 6.0 Km/W, and the thermal resistance coefficient ren of low smoke and zero halogen sheath material is 3.5 Km/W, is not enough to reduce cable surface temperature rise.
Summary of the invention
Primary and foremost purpose of the present invention is, overcomes problems of the prior art, and provide a kind of naval vessel high current-carrying capacity low surface temperature rise cable sheath rubber, thermal resistance coefficient ren is high, and heat-insulating property is good, when cross-sectional area of conductor amasss identical, can improve current capacity.
For solving above technical problem, the invention provides the low surface temperature rise cable sheath rubber of a kind of naval vessel high current-carrying capacity, feed composition and the weight content of described jacket rubber are as follows, LEVAPREN 500HV rubber: 10 parts; Terpolymer EP rubber 4045M:10 part; Dual-tert-butyl peroxy isopropyl base benzene: 0.6 ~ 1 part; Triallyl cyanurate: 0.2 ~ 0.4 part; Vinyl three ('beta '-methoxy oxyethyl group) silane: 0.2 ~ 0.5 part; Stearic acid: 0.5 ~ 1 part; Aluminium hydroxide: 30 ~ 35 parts; Thermal silica: 6 ~ 10 parts; N550 carbon black: 0.6 ~ 1 part; Polyethylene wax: 1.5 ~ 2.5 parts; Alkylated diphenylamine: 0.2 ~ 0.4 part; Zinc borate: 2 ~ 5 parts.
Relative to prior art, the present invention achieves following beneficial effect: (1) LEVAPREN 500HV rubber is along with the increase of wherein vinyl acetate content, the crosslinkable degree of sizing material, oil-proofness, elongation at break can significantly increase, but when vinyl acetate content is greater than 55%, the high thermal resistance of LEVAPREN 500HV rubber and elasticity can decline, and affect flexibility; The present invention is based on vulcanized rubber need to possess the high current-carrying capacity of high temperature resistant guarantee cable and select LEVAPREN 500HV rubber; The molecular structure of LEVAPREN 500HV rubber is saturated methyne main chain simultaneously, and containing polarity side base, nonpolar methin groups and suitable activity, there is high flame retardant, heat-proof aging, oil resistance, and vulcanization crosslinking can be carried out by cheap superoxide, but the price of LEVAPREN 500HV rubber is higher.(2) terpolymer EP rubber 4045M belongs to saturated copolymer, and not containing unsaturated double-bond, available peroxide cure, has excellent resistance to ozone ageing, heat-resisting weather-resistant property, process industrial art performance, cheap, but oil-proofness and poor adhesion.Adopt second Warburg Pincus rubber LEVAPREN 500HV and terpolymer EP rubber 4045M to share the overall performance that can play the two respective advantage, improve sizing material, reduce costs.(3) adopt aluminium hydroxide (i.e. hydrated aluminum oxide) as fire retardant; it contains 3 water moleculess; start to decompose at 250 DEG C; discharge water molecules and absorb heat and reduce surrounding temperature; the water vapour discharged serves again the effect of combustable gas concentration in dilution gas phase, and the aluminium sesquioxide of generation and the carbide on burning polymer surface combine, and form protective membrane; cut off the intrusion of heat energy and oxygen, serve fire retardation.Hydrated aluminum oxide has low cigarette and reduces the effect of carbon monoxide generation, environment-protecting clean simultaneously.(4) namely zinc borate sells fumicants as the synergistic fire retardant of aluminium hydroxide, not only can discharge crystal water and absorb large calorimetric after being heated, and limiting material temperature rises, reduce jacket surface temperature, can also boron chloride be formed, zinc chloride covers material surface, play heat insulation, oxygen barrier, prevent flue gas from overflowing.(5) adopt dual-tert-butyl peroxy isopropyl base benzene and vulcanizing agent BIPB to replace traditional DCP to have obvious advantage: DCP produces niff when crosslinked, and stays in goods; BIPB is without this shortcoming; BIPB temperature resistant grade is high, can carry out mixing at high 10 DEG C than DCP; BIPB contains two peroxide bridges, and active o content is high, amount ratio DCP few 30%; BIPB volatility is low simultaneously, can avoid the bubble caused by methane; But BIPB decomposes in rubber stock produces radical, cause crosslinking reaction, also there is the cut-out of propylene chain link in rubber backbone simultaneously, the thermotolerance of vulcanized rubber can be improved, improve compression set, reduce embrittlement temperature, improve low temperature and deflect performance, but BIPB is when vulcanized rubber, the ionic decomposition occurred can reduce the utilising efficiency of BIPB, and cross-linking density is low, bad mechanical property, and aging is poor; (6) adopt triallyl cyanurate and TAC as co-curing agent, utilize the unsaturated active group that TAC co-curing agent exists, the free radical reaction that rapid and BIPB decomposites, form constitutionally stable new radical, and continue to participate in crosslinking reaction, thus improve utilization ratio and the cross-linking efficiency of BIPB, improve the vulcanization rate of sizing material, cross-linking density and tensile strength, ensure the over-all properties of cross-linked rubber.Alkylated diphenylamine and antioxidant D DA high effect nontoxic, volatility little, have special protective effect and antifatigue effect to aging caused by heat, light, ozone, especially be outstanding to the anti-aging effect of the rubber item requiring to use under the high temperature conditions and antifatigue effect, and with second Warburg Pincus rubber LEVAPREN 500HV and terpolymer EP rubber 4045M with there is good describing property.(8) stearic acid can play the dual function of promoting agent and lubricant as lubricant, makes vulcanizing agent metal oxide have larger activity, better to the dispersiveness of carbon black N550 in sizing material, has the effect of releasing agent simultaneously, is beneficial to sizing material and mould adhesion; Also the process industrial art performance of Insulation Material can be improved, improve processing speed, the quality of sizing material can be improved simultaneously, prevent sizing material from adding the adhesion on man-hour and equipment and other contact material surfaces, sizing material in the course of processing is had good in roller and release property, ensure sizing material any surface finish, reduce kinetic viscosity when sizing material internal friction and melting, prevent from causing because of internal friction sizing material to cross heat affecting use properties.(9) N550 carbon black can improve the ultraviolet-resistant aging performance of sizing material as tinting material, has strengthening action to sizing material simultaneously.(10) thermal silica is as strengthening agent, for the cotton-shaped translucent solid colloidal nanoparticle of white-amorphous, by the halogenide nano level white powder that pyrohydrolysis generates in oxyhydrogen flame of silicon, particle diameter is little, and specific surface area is large, sizing material can be made to have higher physical strength, processing performance is good, and tensile strength is high, but the impact of thermal silica particle surface group acidity, sulfuration can be postponed, large, the mixing easy roll banding of sizing material viscosity.Due to the mooney viscosity of LEVAPREN 500HV low, mixing time easy roll banding, add vinyl three ('beta '-methoxy oxyethyl group) silane and coupling agent A-172 and softening agent polyethylene wax, improve complete processing.Coupling agent A-172 is undersaturated silane, it can coupling spontaneous with thermal silica, the viscosity of remarkable reduction stopping composition granularity and sizing material, improve on the one hand the wetting property of rubber and strengthening agent, weighting agent, rubber one filler key is formed by unsaturated link(age) on the other hand in sulfidation, play and increase vulcanization rate, the tensile strength strengthening cross-linked rubber and water-resistant stability, eliminate the effect of high temperature vulcanized generation pore.Polyethylene wax viscosity is low, and softening temperature is high, nontoxic, Heat stability is good, the large high-temperature volatile of molecular weight is low, and chemical-resistant resistance ability is strong, and electrical property is excellent, and the outward appearance can improving finished product can the diffusion of reinforcing filler, improve extrusion molding speed, increase mould flow, the demoulding is convenient.Tensile strength before jacket rubber of the present invention is aging can reach 11 more than N/mm2, and elongation at break can reach more than 190%; Tensile strength retention rate after air oven is aging can reach more than 61%, and reserved elongation at break can reach more than 62%; Under degree of crosslinking test load, elongation can reach less than 18%; Thermal resistance coefficient ren can reach more than 6.1Km/W; Acid gas content, content of halogen, poison exponent, smoke index etc. are all better than standard-required.
