Abstract
The invention discloses a double-sheath structured degaussing cable comprising copper conductors which are arranged at the centermost of the cable. An isolation tape extrudes outside the copper conductors. A rubber insulating layer and a rubber internal sheath respectively extrude outside the isolation tape by adopting a double layer co-extrusion mode. Finally an external sheath formed by polyurethane with adding of a hydrolysis resistant agent and thickness of 0.375-0.525mm extrudes outside the rubber internal sheath. The double-sheath structure is adopted, and the external sheath adopts polyurethane material so that marine organism preventing performance of the cable is enhanced. Meanwhile, the cable is great in cable flexible performance, convenient for laying, great in water resistance performance and high in production efficiency of the product.
Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of duplex sheath structure degaussing cable.
Background technology
The effect of degaussing cable is ship deperming, have fixedly to lay and move and lay two kinds, because the cable Long-Time Service of the type is having in briny environment, therefore, such cable is because having good weather-proof, salt spray resistance, and current used cable can reach this requirement substantially, but along with the Long-Time Service of cable, cable is very easily subject to marine organisms or other microbes parasitism corrodes, and easily punctures, thus reduces the useful life of cable.In order to address this problem, in prior art, Chinese patent " 201020174851.5 " discloses a kind of warship high-performance degaussing cable, have employed duplex sheath structure, i.e. neoprene inner sheath and IXPE oversheath, its principle is that oversheath adopts IXPE material to form, its smooth surface, marine microorganism is not easy parasitism, therefore can slow down the parasitic corrosion of microbe to cable aging.
Prior art is adopted to have following problem:
1, adopt crosslinked polyethylene as oversheath, because material is comparatively hard, the complete poor performance of finished cable, its bending radius reaches more than 12 times, the laying and using of inconvenient cable;
2, the block-water performance of cable is poor, is having the useful life of cross-linking polyethylene materials in briny environment low for a long time;
3, owing to needing to be cross-linked in cross-linking polyethylene materials production process, production technology is comparatively complicated, and production efficiency is low, owing to have employed the mode of cross-linking radiation, has certain radiation injury, has certain potential hazard to producers.
Summary of the invention
The present invention, in order to solve the problem of prior art, provides that a kind of production efficiency is high, simple process, and production process is without harm, and anti-marine growth performance, softness are good, the duplex sheath structure degaussing cable that block-water performance is good.
A kind of duplex sheath structure degaussing cable of the present invention, comprise the copper conductor being arranged on cable bosom, isolation strip is extruded outside copper conductor, outside isolation strip, adopt the mode of double-layer coextrusion to extrude rubber insulation and rubber inner sheath respectively, outside rubber inner sheath, finally extrude thickness is the oversheath that polyurethane that the employing of 0.375-0.525mm adds hydrolysis agent is formed.
Further improvement, the thickness of described rubber insulation is 2 times of isolation strip thickness, and wherein, the thickness of rubber insulation is 1.75-3.75mm.
Further improvement, the thickness of described rubber inner sheath is 2 times of rubber-covered layer thickness.
Compared with prior art, beneficial effect of the present invention is:
1, the invention protect in have employed+protect duplex sheath structure outward, be characterized in that oversheath have employed polyurethane material and forms, compared with prior art, oversheath adopts its production technology of polyurethane easy, do not need to carry out cross-linking radiation after extruding oversheath, can enhance productivity, decrease the impact of cross-linking radiation on operating personnel simultaneously.
2, the oversheath of the invention is that polyurethane material is formed, and in polyurethane material, add hydrolysis agent, the block-water performance of cable in briny environment can be ensured like this, simultaneously because the flexibility of polyurethane material is very good, therefore, the good bending property of finished cable, its bending radius reaches 4 times of the outside diameter of cable.
3, oversheath adopts polyurethane material to form, and has intensity high, the advantage that tear-proof, percentage elongation are good, has lightweight advantage simultaneously, very conveniently manually to lay.
4, the oversheath of polyurethane material formation, its surface is very smooth, can ensure the useful life under salt mist environment for a long time, and self-cleaning ability is strong simultaneously, and marine growth is difficult to be attached to cable surface, and compared with prior art, its useful life adds more than 2 times.
5, take inner sheath to from isolation, the thickness of every layer is all increase progressively 2 times, this ensure that the overall rounding property of cable, makes each performance of cable better.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of duplex sheath structure degaussing cable as shown in Figure 1, comprise the copper conductor 1 being arranged on cable bosom, isolation strip 2 is extruded outside copper conductor 1, in isolation strip 2, the outer mode of double-layer coextrusion that adopts extrudes rubber insulation 3 and rubber inner sheath 4 respectively, the last thickness that extrudes outside rubber inner sheath is the oversheath 5 that polyurethane that the employing of 0.375-0.525mm adds hydrolysis agent is formed, protect in this construction of cable have employed+protect duplex sheath structure outward, be characterized in that oversheath have employed polyurethane material and forms, compared with prior art, oversheath adopts its production technology of polyurethane easy, do not need to carry out cross-linking radiation after extruding oversheath, can enhance productivity, decrease the impact of cross-linking radiation on operating personnel simultaneously,
Better improved to make cable, hydrolysis agent is added in the polyurethane material forming oversheath, the block-water performance of cable in briny environment can be ensured like this, simultaneously because the flexibility of polyurethane material is very good, therefore, the good bending property of finished cable, its bending radius reaches 4 times of the outside diameter of cable; Oversheath adopts polyurethane material to form, and has intensity high, the advantage that tear-proof, percentage elongation are good, has lightweight advantage simultaneously, very conveniently manually to lay; The oversheath that polyurethane material is formed, its surface is very smooth, can ensure the useful life under salt mist environment for a long time, and self-cleaning ability is strong simultaneously, and marine growth is difficult to be attached to cable surface, and compared with prior art, its useful life adds more than 2 times.
This cable takes between inner sheath from isolation, and the thickness of every layer is all increase progressively 2 times, and wherein, the thickness of rubber insulation is 1.75-3.75mm, this ensure that the overall rounding property of cable, makes each performance of cable better.
Embody rule approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
