Abstract
The utility model discloses a double -deck sheath structure degaussing cable, including the copper conductor of setting in the cable bosom, the crowded median of wrapping outside the copper conductor adopts double -deck mode of crowding altogether to divide don't push rubber coating insulating layer and rubber inner sheath, the last oversheath of crowding package thickness and having added hydrolysis resisting agent's polyurethane component for 0.375 -0.525mm's adoption outside the rubber inner sheath outside the median. The utility model discloses a double -deck sheath structure, the oversheath has adopted the polyurethane material, has improved the extra large biological ability of preventing of cable, and the cable compliance of cable can be good simultaneously, conveniently lays, and the block -water performance is good, and the production efficiency of product is high.
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 for ship deperming, have to fix to lay and move and lay two kinds, owing to the cable life-time service of the type is in having briny environment, therefore, such cable is because having good weather-proof, salt spray resistance, and current used cable can reach this requirement substantially, but it is as the life-time service of cable, cable is extremely easily subject to marine organisms or other microorganism parasitisms corrode, it is easy to puncture, thus reducing the service life of cable.In order to solve 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 in that oversheath adopts IXPE material to constitute, its smooth surface, Marine microorganism is not easy parasitism, therefore can slow down microorganism the parasitic corrosion of cable is aging.
Prior art is adopted to have problems with:
1, adopting crosslinked polyethylene as oversheath, owing to material is harder, the complete poor performance of finished cable, its bending radius has reached more than 12 times, it has not been convenient to the laying and using of cable；
2, the block-water performance of cable is poor, and in having briny environment, the service life of cross-linking polyethylene materials is low for a long time；
3, owing to needing crosslinking in cross-linking polyethylene materials production process, production technology is complex, and production efficiency is low, owing to have employed the mode of cross-linking radiation, has certain radiation injury, producers have certain potential hazard.
Summary of the invention
The present invention is to solve problem of the prior art, it is provided that a kind of production efficiency is high, simple process, and production process non-hazardous, 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, including the copper conductor being arranged on cable bosom, isolation strip is extruded outside copper conductor, the mode adopting double-layer coextrusion outside isolation strip extrudes rubber insulation and rubber inner sheath respectively, finally extrudes the oversheath that thickness is 0.375-0.525mm outside rubber inner sheath.
Improving further, 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.
Improving further, the thickness of described rubber inner sheath is 2 times of rubber-covered layer thickness.
Compared with prior art, the present invention has the beneficial effects that:
1, the invention protect in have employed+protect outward duplex sheath structure, it is characterized in that oversheath have employed polyurethane material and constitutes, compared with prior art, oversheath adopts its production technology of polyurethane easy, cross-linking radiation need not be carried out after extruding oversheath, production efficiency can be improved, decrease the cross-linking radiation impact on operator simultaneously.
2, the oversheath of the invention is that polyurethane material is constituted, and in polyurethane material, add hydrolysis agent, so can ensure that cable block-water performance in briny environment, simultaneously because the flexibility of polyurethane material is very good, therefore, the good bending property of finished cable, its bending radius has reached 4 times of the outside diameter of cable.
3, oversheath adopts polyurethane material to constitute, and has intensity height, the advantage that anti tear, percentage elongation are good, has lightweight advantage simultaneously, very convenient manually lays.
4, the oversheath that polyurethane material is constituted, its surface is extremely smooth, can ensure the service 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 service life adds more than 2 times.
5, taking inner sheath to from isolation, the thickness of every layer is all incremented by 2 times, this ensure that the overall rounding property of cable so that each performance of cable is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
A kind of duplex sheath structure degaussing cable as shown in Figure 1, including 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 adopting double-layer coextrusion extrudes rubber insulation 3 and rubber inner sheath 4 respectively, outside rubber inner sheath, finally extrude the employing that thickness is 0.375-0.525mm add the oversheath 5 that the polyurethane of hydrolysis agent is constituted, this construction of cable protects in have employed+protect outward duplex sheath structure, it is characterized in that oversheath have employed polyurethane material and constitutes, compared with prior art, oversheath adopts its production technology of polyurethane easy, cross-linking radiation need not be carried out after extruding oversheath, production efficiency can be improved, decrease the cross-linking radiation impact on operator simultaneously；
In order to make cable better be improved, the polyurethane material constituting oversheath adds hydrolysis agent, so can ensure that cable block-water performance in briny environment, simultaneously because the flexibility of polyurethane material is very good, therefore, the good bending property of finished cable, its bending radius has reached 4 times of the outside diameter of cable；Oversheath adopts polyurethane material to constitute, and has intensity height, the advantage that anti tear, percentage elongation are good, has lightweight advantage simultaneously, very convenient manually lays；The oversheath that polyurethane material is constituted, its surface is extremely smooth, can ensure the service 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 service life adds more than 2 times.
This cable takes between inner sheath from isolation, and the thickness of every layer is all incremented by 2 times, and wherein, the thickness of rubber insulation is 1.75-3.75mm, this ensure that the overall rounding property of cable so that each performance of cable is better.
The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, it should be pointed out that; for those skilled in the art; under the premise without departing from the principles of the invention, it is also possible to make some improvement, these improvement also should be regarded as protection scope of the present invention.
