Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the underwater high-definition comprehensive towline cable comprises a cable core 1, a cable core protective layer 2, a shielding layer 3, a shielding layer protective layer 4 and an outer sheath 5.

The cable core 1 comprises a CAT6 net wire 11, a signal wire 12 and two power wires 13, wherein the CAT6 net wire 11, the signal wire 12 and the two power wires 13 are twisted.

The CAT6 network cable 11 comprises eight network cable cores 111, every two network cable cores 111 form a group, a signal shielding layer 112 wraps the outside of each group of network cable cores 111, the four groups of network cable cores 111 are arranged in a rectangular shape, and a network cable wrapping layer 113 wraps the outside of the shielding layer 112 together. The net twine sinle silk 111 wraps up in shielding layer 112 after twisting each other with the carbon fiber rope.

Because net twine sinle silk 111 in CAT6 net twine 11 adopts eight core structures to net twine sinle silk 111 still wraps up in shielding layer 112 after through twisting each other with the carbon fiber rope, has prevented the noise interference of playing between net twine sinle silk 111, has improved the interference killing feature of cable. Eight network cable cores 111 are divided into four groups and are arranged in a rectangular shape to be wrapped in a network cable wrapping layer 113, a certain movable room is reserved for the network cable cores 111, and therefore in the cable dragging process, the network cable cores 111 are not bent or stretched to cause disconnection of the network cable cores 111 to be controlled, and production is not affected.

The signal wire 12 includes an optical cable 121, a plurality of twisted pairs 122 surrounding the optical cable 121, and a signal wire wrapping layer 123 and a signal wire outer sheath 124 sequentially wrapping the twisted pairs 122 from inside to outside. The optical cable 121 includes five cores.

The cable core 11 further comprises a tensile filling layer 14, wherein the tensile filling layer 14 comprises tensile filling cotton ropes and tensile fillers, and the tensile filling cotton ropes are axially arranged in gaps of the cable core 11. The cable core sheath 2 covers the cable core 1.

The tensile filler is obtained by blending the following components in parts by weight: 60 parts of LLDPE-7042; 20 parts of HDPE-TR 144; 20 parts of HDPE-2200J; the lubricant is 0.8 part. The selection of proper PE resin is a crucial step for designing the tensile filler for the wires and cables, and the performance of the PE resin is directly related to the physical mechanical property and the electrical property of the tensile filler and the forming and processing performance of the tensile filler. When the cable is laid, the stress cracking phenomenon easily occurs under the stress action, so that the cable is damaged. Although Linear Low Density Polyethylene (LLDPE) has excellent anti-cracking performance, when LLDPE is extruded, the extrusion rate is high, which causes some processing defects, so that the single use of LLDPE is difficult to meet the requirement, and tensile filler with excellent processing performance is obtained by blending modification.

The relative molecular mass of the PE resin has a great influence on the anti-cracking performance, the PE resin with large relative molecular mass, namely small melt flow rate, has good anti-cracking performance, and the PE resin for the tensile filler requires small melt flow rate. The High Density Polyethylene (HDPE) has lower molecular branching degree, more regular chain segment arrangement and better anti-cracking performance, so that LLDPE with lower melt flow rate and HDPE are selected for blending.

The addition of a small amount of polyethylene wax lubricant to the PE resin can reduce the mechanical friction and polymer internal friction of the PE material in processing.

7042 has a melt flow rate of 0.782g/10min, excellent cracking resistance and low cost, so 7042 is selected as the blended base resin; the melt flow rate of TR144 is 0.091 g/10min, the anti-cracking performance is excellent, but because the relative molecular mass and the melt viscosity of TR144 are both larger, the processing and forming are more difficult, and the price of TR144 is also more expensive, the problems of more difficult processing and forming and higher price need to be overcome by adopting blending modification. The melt flow rate of 2200J is 2.170 g/10min, the processing and forming performance is better, the anti-cracking performance is poorer than that of TR144, and the blending of TR144 and 2200J together with 7042 can play a good complementary role.

3 cladding of shielding layer the cable core sheath 2, shielding layer 3 is woven by galvanized copper wire, carbon fiber, nickel-plated copper wire and tinned wire and is formed, the carbon fiber is as warp, the galvanized copper wire the nickel-plated copper wire with the even interval of tinned wire is as weft.

The shielding layer sheath 4 covers the shielding layer 3. The outer sheath 5 covers the shielding layer sheath 4.

The outer sheath 5 is obtained by mixing blended rubber and a sizing material: the weight ratio of the rubber material to the blending rubber is 1: 7-8.5; the blend rubber is formed by melting and blending EPR and CSP, the weight ratio of EPR to CSP is 1:0.25-0.75, and the EPR and CSP are mixed for 10min on a double-roller open mill with the roller temperature of 30 ℃; the rubber material comprises the following components in parts by weight: 100 parts of polymer, 1 part of anti-aging agent, 84 parts of mineral filler, 10 parts of carbon black, 8 parts of process oil, 2 parts of process additive, 1.5 parts of coupling agent, 10 parts of magnesium oxide, 7 parts of 40% DCP solution and 0.3 part of sulfur; and (3) mixing the mixture of the rubber material and the co-mixed rubber on a double-roll open mill with the roller temperature of 30 ℃ for 35min, adding a vulcanizing agent, and mixing for 10min to obtain the rubber compound. Because the modified blended outer sheath is adopted, the outer sheath 5 has higher tensile strength and tearing strength than common rubber, maintains flexibility, has better wear resistance and has oil resistance and corrosion resistance.

The natural rubber is easy to degrade when being irradiated by sunlight, particularly ultraviolet light, so that the cable outer sheath 5 is added with a light stabilizer, and the carbon black is an economic and efficient light shielding agent.

In addition to the preferred embodiments described above, other embodiments of the present invention are also possible, and those skilled in the art can make various changes and modifications according to the present invention without departing from the spirit of the present invention, which should fall within the scope of the present invention defined by the appended claims.
