Abstract
A moisture-proof corrosion-proof coaxial cable comprises an inner conductor, an insulating layer, an outer conductor and an outer sheath, wherein an inner crusting layer is arranged between the inner conductor and the insulating layer; the outer conductor is composed of an aluminum foil layer and a weave layer; a filling layer is arranged between the outer conductor and the outer sheath; and the inner conductor, the inner crusting layer, the insulating layer, the aluminum foil layer, the weave layer, the filling layer and the outer sheath are radially arranged from inside to outside in sequence. Self-prepared mineral oil mixture is employed, so that corrosions of moisture and saline solution on aluminum foil and woven wire are prevented and metal oxidation resistance performance is good; the self-prepared mineral oil mixture is employed, so that, during production, filling process is simple and convenient, production efficiency is high and quality is stable; the self-prepared mineral oil mixture, which is a high molecular weight organic matter itself, effectively controls filling amount, helps to solve the problem of incompatibility between traditional ointments and cable sheath materials and meanwhile the transmission performance of the cable is not influenced.
Description
(1) technical field
The present invention relates to a kind of cable, specifically a kind of Dampproof corrosion-protected coaxial cable.
(2) background technology
Coaxial cable is in case corroded by moisture, moisture, the material such as saline and alkaline, and outer conductor will oxide etch, and the aluminium foil of outer conductor and braided wires gradually embrittlement are rotten, thereby causes electric and physical characteristic worsens, and loses the use function.
And the way of usually taking at present is to fill between outer conductor and sheath with moistureproof rust preventive oil cream.Use this measure to have the following disadvantages:
1) anticorrosion ointment itself just contains certain moisture, processes badly to run counter to desire on the contrary;
2) there are consistency problem in ointment and sheath material, and consumption is large, and ointment can be separated out by jacket surface, or force in the sheath little molecule to be separated out;
3) use adds the ointment method, controls aborning difficulty larger, and operating personnel relatively dislike;
Addition relatively was difficult to control when 4) waterproofing unction was produced, and the quality problems that cause are more, and waste is large, and production efficiency is low.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the technical problem to be solved in the present invention provides a kind of Dampproof corrosion-protected coaxial cable, adopt the mineral oil anti-corrosive mixture of new autogamy, substitute original ointment, be filled between outer conductor and the sheath, both had good anticorrosive property, and also solved the consistency problem with cable sheath material, transmission performance is also unaffected.Loading is easily controlled during simultaneously actual production, steady quality, and production efficiency is high.
For this reason, the present invention takes following technical scheme:
A kind of moisture-proof anticorrosive erosion coaxial cable, include inner wire, insulating barrier, outer conductor and oversheath, interior skinning cortex is arranged between described inner wire and the insulating barrier, described outer conductor is comprised of aluminium foil layer and braid, be provided with packed layer between described outer conductor and the oversheath, described inner wire, interior skinning cortex, insulating barrier, aluminium foil layer, braid, packed layer and oversheath radially arrange successively from inside to outside.
Described packed layer is a kind of mineral oil mixture of autogamy, and mineral oil mixture is a kind of semi liquid state mixture, can realize filling by the mode that drips or spray before the extrusion head of sheath production.
The prescription of described mineral oil mixture is: mineral oil A, mineral oil B, antioxidant, its part by weight are (80-85): (14-19): (0.8-1.2); The Chinese wax oil that described mineral oil A is a kind of HMW, main component is the mixture of the positive isoparaffin of C16~C31; The Chinese wax oil that described mineral oil B is another kind of HMW, main component is the mixture of the positive isoparaffin of C16~C31.
Advantage of the present invention is: 1, adopt the mineral oil mixture of autogamy, can stop the corrosion of the external conductor foil of moisture and salt solution and braided wires, have the effect of good anti-burning; 2, adopt the mineral oil mixture of autogamy, realize during production that the technique of filling is simple and convenient, production efficiency is high, steady quality; 3, the mineral oil mixture of autogamy originally as high score amount organic substance, and has effectively been controlled loading, has solved the incompatibility problem of traditional ointment and cable sheath material, and the transmission performance of cable is also unaffected simultaneously.
(4) description of drawings
Fig. 1 is structure cross-sectional schematic of the present invention;
Wherein, skinning cortex in the 1-inner wire, 2-, 3-insulating barrier, 5-packed layer, 6-oversheath, 7-aluminium foil layer, 8-braid.
(5) specific embodiment
With reference to accompanying drawing 1, a kind of moisture-proof anticorrosive erosion coaxial cable, include inner wire 1, insulating barrier 3, outer conductor and oversheath 6, interior skinning cortex 2 is arranged between described inner wire and the insulating barrier, described outer conductor is comprised of aluminium foil layer 7 and braid 8, be provided with packed layer 5 between described outer conductor and the oversheath, described inner wire, interior skinning cortex, insulating barrier, aluminium foil layer, braid, packed layer and oversheath radially arrange successively from inside to outside.Described packed layer is a kind of mineral oil mixture of autogamy, and mineral oil mixture is a kind of semi liquid state mixture, can realize filling by the mode that drips or spray before the extrusion head of sheath production.The prescription of described mineral oil mixture is: mineral oil A, mineral oil B, antioxidant, its part by weight are (80-85): (14-19): (0.8-1.2); Described mineral oil A is a kind of organic substance of HMW, is a kind of Chinese wax oil of HMW, and main component is the mixture of the positive isoparaffin of C16~C31, and is colourless, tasteless, has good oxidation stability, chemical stability, light stability.The trade mark is DASCOLUBE AW 32; The Chinese wax oil that described mineral oil B is another kind of HMW, main component is the mixture of the positive isoparaffin of C16~C31, and is colourless, tasteless, has good oxidation stability, chemical stability, light stability.The trade mark is KX1101.Described antioxidant is a kind of novel environmental protection antioxidant, and the antioxidant anticorrosive of the metals such as copper, aluminium is had good protection effect.The trade mark is MK-PC.During use load weighted each batching is added to successively to mix in the mixer and gets final product packed for standby use.
The cable finished product that makes carries out the outer conductor corrosion resistance test according to U.S. SCTE standard, and the result is all qualified, and is respond well.Simultaneously, the technique simple and feasible, production efficiency is high, steady quality, percent defective reduces greatly.
