With respect to prior art, the present invention has obtained following beneficial effect: form flat outward, can close-packed arrays between adjacent cable during layout, and take up room little, especially can reduce the thickness of degaussing cable, the integral arrangement surfacing; What the outer wall of insulated wire cores adopted is high thermal resistivity chemical crosslinking polyolefin oversheath, can reduce the temperature of cable outer wall.
As preferred version of the present invention, raw material components and the weight content of described high thermal resistivity chemical crosslinking polyolefin inner sheath and high thermal resistivity chemical crosslinking polyolefin oversheath are as follows, LEVAPREN 500HV rubber: 10 parts; Ethylene propylene diene 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 ethyoxyl) silane: 0.2 ~ 0.5 part; Stearic acid: 0.5 ~ 1 part; Aluminium hydroxide: 30 ~ 35 parts; Fume colloidal silica: 6 ~ 10 parts; N550 carbon black: 0.6 ~ 1 part; Tissuemat E: 1.5 ~ 2.5 parts; Alkylated diphenylamine: 0.2 ~ 0.4 part; Firebrake ZB: 2 ~ 5 parts.This sheath is obtained following beneficial effect: (1) LEVAPREN 500HV rubber is along with the wherein increase of vinyl acetate content, the crosslinkable degree of sizing material, oil resistance, elongation at break can significantly increase, but when vinyl acetate content is greater than 55%, the heat-resisting quantity of LEVAPREN 500HV rubber and elasticity can descend, and affect flexibility; The present invention is based on vulcanized rubber need to possess the high current-carrying capacity of high temperature resistant assurance cable and select LEVAPREN 500HV rubber; The molecular structure of LEVAPREN 500HV rubber is saturated methine main chain simultaneously, and contain polarity side group, nonpolar methine group and suitable activity, there is high flame retardant, heat-proof aging, oil resistance, and can carry out vulcanization crosslinking by cheap peroxide, but the price of LEVAPREN 500HV rubber is higher.(2) ethylene propylene diene rubber 4045M belongs to saturated copolymer, does not contain unsaturated double-bond, and available peroxide cure has excellent anti-ozone aging, heat-resisting weather-resistant property, process industrial art performance, cheap, but oil resistance and poor adhesion.Adopt second Warburg Pincus rubber LEVAPREN 500HV and ethylene propylene diene rubber 4045M to share and can bring into play the two advantage separately, the overall performance of raising sizing material, reduce costs.(3) adopt aluminium hydroxide (being hydrated alumina) as fire retardant; it contains 3 hydrones; at 250 ℃, start to decompose; discharge hydrone and absorb heat and reduced environment temperature; the steam discharged has played again the effect of combustable gas concentration in the dilution gas phase, and the carbide combination of the alundum (Al2O3) of generation and burning polymer surfaces, form diaphragm; cut off the intrusion of heat energy and oxygen, played fire retardation.Hydrated alumina has low cigarette and reduces the effect that carbon monoxide occurs, environment-protecting clean simultaneously.(4) Firebrake ZB sells fumicants as the synergistic fire retardant of aluminium hydroxide, not only can discharge the crystallization water after being heated and absorb large calorimetric, and the limiting material temperature rises, reduce the jacket surface temperature, can also form boron chloride, zinc chloride covers material surface, plays heat insulation, oxygen barrier, prevents that flue gas from overflowing.(5) adopting dual-tert-butyl peroxy isopropyl base benzene is that vulcanizing agent BIPB replaces traditional DCP to have obvious advantage: DCP producing niff when crosslinked, and stays in goods; BIPB is without this shortcoming; The BIPB temperature resistant grade is high, can under high 10 ℃ than DCP, carry out mixing; BIPB contains two peroxide bridges, and active o content is high, and amount ratio DCP few 30%; The BIPB volatility is low simultaneously, can avoid the bubble caused by methane; But BIPB decomposes in rubber composition produces free radical, cause cross-linking reaction, the cut-out of propylene chain link on rubber backbone also occurs simultaneously, can improve vulcanized rubber thermal endurance, improve compression, reduce brittle temperature, improve low temperature and deflect performance, but BIPB is when vulcanized rubber, the ionic occurred decomposes the utilization ratio that can reduce BIPB, and crosslink density is low, bad mechanical property, and aging is poor; (6) adopting triallyl cyanurate is that TAC is as co-curing agent, the unsaturated active group that utilizes the TAC co-curing agent to exist, the radical reaction rapid and BIPB decomposites, form constitutionally stable new free radical, and sustainable participation cross-linking reaction, thereby improve utilance and the cross-linking efficiency of BIPB, improve curingprocess rate, crosslink density and the hot strength of sizing material, guarantee the combination property of vulcanizate.Alkylated diphenylamine be antioxidant D DA high effect nontoxic, volatility little, to heat, light, ozone caused aging have special protective action and antifatigue effect, especially to the anti-aging effect of the rubber that requires to use under hot conditions and antifatigue effect for outstanding, and with second Warburg Pincus rubber LEVAPREN 500HV and ethylene propylene diene rubber 4045M with good describing property is arranged.(8) stearic acid can play the double action of activating agent and lubricant as lubricant, makes the vulcanizing agent metal oxide have larger activity, and the dispersiveness to carbon black N550 in sizing material is better, has the effect of release agent simultaneously, is beneficial to sizing material and mould adhesion; Also can improve the process industrial art performance of Insulation Material, improve processing speed, can improve the quality of sizing material simultaneously, prevent that 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, guarantee the sizing material any surface finish, the kinematic viscosity while reducing sizing material internal friction and melting, prevent from crossing the thermal impact serviceability because internal friction causes sizing material.(9) the N550 carbon black can improve the ultraviolet-resistant aging performance of sizing material as colouring agent, sizing material is had to strengthening action simultaneously.(10) fume colloidal silica is as reinforcing agent, for the gluey nano particle of the amorphous cotton-shaped translucent solid of white, by the halide nanoscale white powder that pyrohydrolysis generates in oxyhydrogen flame of silicon, particle diameter is little, and specific area is large, can be so that sizing material has higher mechanical strength, processing performance is good, and hot strength is high, but the impact of fume colloidal silica particle surface group acidity, can postpone sulfuration, large, the mixing easy roll banding of sizing material viscosity.Due to the Mooney viscosity of LEVAPREN 500HV easy roll banding when low, mixing, adding vinyl three ('beta '-methoxy ethyoxyl) silane is coupling agent A-172 and plasticizer Tissuemat E, improves processing technology.Coupling agent A-172 is undersaturated silane, it can with the spontaneous coupling of fume colloidal silica, significantly reduce the viscosity of inserts granularity and sizing material, improve on the one hand the wettability of rubber and reinforcing agent, filler, form rubber one filler key by unsaturated bond on the other hand in sulfidation, play the tensile strength and the water-resistant stability that increase curingprocess rate, strengthen vulcanizate, eliminate the effect of high temperature vulcanized generation pore.Tissuemat E viscosity is low, and softening point is high, nontoxic, Heat stability is good, the large high-temperature volatile of molecular weight is low, and the chemical-resistant resistance ability is strong, and electrical property is good, but can improve the diffusion of the outward appearance reinforcing filler of finished product, improve extrusion modling speed, increase the mould flow, demoulding facility.More than tensile strength before high thermal resistivity chemical crosslinking polyolefin oversheath of the present invention is aging can reach 11 N/mm2, 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 cross linking test load, percentage elongation can reach below 18%;
