Abstract
A seawater-corrosion-resistant coaxial cable comprises an inner conductor, an insulating layer, an outer conductor and an outer sheath, wherein the outer conductor is composed of an aluminum foil layer and a weave layer, an inner crust layer is arranged between the inner conductor and the insulating layer, and the inner conductor, the inner crust layer, the insulating layer, the aluminum foil layer, the weave layer and the outer sheath are axially arranged from the inside out in sequence. Due to the fact that the inner crush layer is arranged between the inner conductor and the insulating layer, the adhesive force of the inner crust layer and the inner conductor of the cable is improved greatly, saline and alkaline moisture is effectively prevented from soaking in the direction of the inner conductor, and the effect of corrosion resistance is achieved. Due to the fact that environmental friendly copper antioxidant without public harm or pollution is used in the inner crust layer, the design of the cable is guaranteed to be environmental friendly, and export risks of the products are reduced. Further, the seawater-corrosion-resistant coaxial cable is simple in technology, compact in structure, low in manufacturing cost and good in using effect.
Description
(1) technical field
The present invention relates to a kind of cable, specifically a kind of seawater corrosion resistance coaxial cable.
(2) background technology
In order to reach the purpose of inner conductor antioxidant anticorrosive, generally take in the thin layer plastics to add a certain proportion of adhesive means method, as the EAA of acrylic compounds etc., or add a certain proportion of copper antioxidant again, anticorrosion ability is good.Such as (patent No.: 200910018304.X), introduced a kind of manufacture method of binding agent dedicated parent material, copper antioxidant wherein is acene triazole (BTA) at a kind of binding agent for physical foaming of communication cable of patent.And copper antioxidant generally adopts acene triazole (BTA) or 2-to dredge basic acene thiazole (MBT) at present, the defective of these two kinds of material maximums all is benzene class material, belong to non-environmental protection material, bring certain influence for like this environmental protection index of product, particularly increased the products export risk.
(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 seawater corrosion coaxial cable, adopt new environment-friendly type copper antioxidant, make the internal layer masterbatch, guaranteed the inner wire anticorrosive property, the transmission performance of cable is unaffected simultaneously, and environmental protection index meets all latest requirement of European Union.
For this reason, the present invention takes following technical scheme:
A kind of seawater corrosion resistance coaxial cable, include inner wire, insulating barrier, outer conductor and oversheath, described outer conductor is made up of aluminium foil layer and braid, interior skinning cortex is arranged between described inner wire and the insulating barrier, and described inner wire, interior skinning cortex, insulating barrier, aluminium foil layer, braid and oversheath radially arrange successively from inside to outside.
Skinning cortex is polyethylene solid plastic thin layer in described, extrudes with the internal layer masterbatch of autogamy to form; The allocation plan of described internal layer masterbatch is: low density polyethylene (LDPE) PE, binding agent EAA, copper antioxidant, its part by weight are 100:(4-6): (0.8-1.2), load weighted each batching is added to successively to mix in the high-speed mixer and gets final product packed for standby use.
Advantage of the present invention is: 1, interior skinning cortex is arranged between inner wire and insulating barrier, greatly improved the bonding force of the interior skinning cortex of cable and inner wire, effectively suppressed saline and alkaline moisture along the infiltration of inner wire direction, played anticorrosion ability; 2, adopt the environment-friendly type copper antioxidant in the interior skinning, do not had any public hazards or pollution, guaranteed the environmental protection design of cable, reduced the products export risk; 3, simple, the compact conformation of production technology, low cost of manufacture, result of use are good.
(4) description of drawings
Fig. 1 is structure cross-sectional schematic of the present invention;
Wherein, 1-inner wire, 2-insulating barrier, 3-outer conductor, skinning cortex in the 4-oversheath, 5-, 6-aluminium foil layer, 7-braid.
(5) specific embodiment
With reference to accompanying drawing 1, a kind of seawater corrosion resistance coaxial cable, include inner wire 1, insulating barrier 2, outer conductor 3 and oversheath 4, described outer conductor is made up of aluminium foil layer 6 and braid 7, interior skinning cortex 5 is arranged between described inner wire and the insulating barrier, and described inner wire 1, interior skinning cortex 5, insulating barrier 2, aluminium foil layer 6, braid 7 and oversheath 4 radially arrange successively from inside to outside.
Skinning cortex is polyethylene solid plastic thin layer in described, extrudes with the internal layer masterbatch of autogamy to form.3002), the copper antioxidant (trade mark: MK-PC low density polyethylene (LDPE) PE(trade mark DGDA1253), the binding agent EAA(trade mark allocation plan of internal layer masterbatch is::, its part by weight is 100:5:1.0, load weighted each batching is added to mix in the high-speed mixer successively get final product packed for standby use.Described copper antioxidant is an environmental protection copper antioxidant, be the antioxidant of the best a new generation of various metals, the trade mark is MK-PC, is that Sakurai company produces according to state-of-the-art technology and state-of-the-art prescription, do not have any public hazards or pollution, meet the requirement of global environmental protection newest standards.
Described aluminium foil layer is close to the vertical bag of foamed insulation by the double-sided self-adhesive foil laminated film and is formed.
Described oversheath adopts the pvc sheath of seawater corrosion resistance.
The cable finished product that makes carries out the inner wire corrosion resistance test according to U.S. SCTE standard, and the result is all qualified, and is respond well.Environmental protection index has passed through the test of SGS center, Shanghai, satisfies the environmental protection index requirement of ROHS and REACH fully.
