Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to a comprehensive cable for an electronic detector. Background Art

[0002] Electronic detectors refer to instruments, equipment and systems that use electronic technology to measure and observe electrical or non-electrical quantities, or light, electrical quantity and measuring accessories for measurement purposes. Measurement includes data acquisition, storage, display, printing, drawing, processing and transmission, etc., and are information products. Integrated cables refer to cables that combine different types of cables. They can not only connect power supplies, but also transmit audio and video signals. They are compact and easy to use, and can improve the sensitivity of electronic detectors.

[0003] Electronic detectors have high requirements for the anti-interference ability of cables. At present, improvements are generally made to the structure of the cables to improve the overall shielding effectiveness of the cables to resist external electromagnetic interference and internal crosstalk; for example, increasing the thickness and multi-level shielding are used to reduce the impact of electromagnetic induction. If the shielding layer is too thick, the cable will be heavier, the outer diameter will be thicker, and it will be difficult to bend, which will make it inconvenient to install and use. In addition, the electromagnetic shielding property will change greatly after bending and deformation, which needs to be improved urgently. Summary of the invention

[0004] The present invention aims to overcome at least one of the above-mentioned shortcomings and deficiencies of the prior art and provide a comprehensive cable for an electronic detector. The purpose of the present invention is achieved based on the following technical solutions:

[0005] The present invention provides an integrated cable for an electronic detector, which comprises a cable core, a wrapped shielding layer and a sheath from the inside to the outside. The cable core has a symmetrical structure, comprising a reinforcing core arranged in the center and conductive wires and signal wires alternately arranged around the surface of the reinforcing core. The reinforcing core, conductive wires and signal wires are twisted with each other. The wrapped shielding layer comprises a flexible insulating layer, a semiconductor layer and a vertical graphene layer from the inside to the outside. The vertical graphene layer grows on the surface of the semiconductor layer. The wrapped shielding layer is spirally wound on the outer surface of the cable core in multiple layers. The sheath is made of ceramic fiber and rare earth oxide-modified rubber.

[0006] The present invention adopts a central symmetrical structure in structural design, which not only has the advantages of small outer diameter, light weight, good bending performance and stable product structure, but also has excellent electrical performance, which is conducive to transportation and installation; a reinforcing core is arranged in the center, which improves the structural strength and service life of the integrated cable. The present invention constructs a multi-layer spirally wrapped semi-conductive-conductive shielding structure, which combines the structure and function of the traditional wrapping layer and the shielding layer into one, and has a novel structure; it can offset the electromagnetic effect layer by layer, and improve the electromagnetic shielding of the present invention; at the same time, the present invention uses vertical graphene instead of metal as a conductor shielding layer, and then cooperates with a semi-conductive layer, which greatly reduces the weight and has a better shielding effect; compared with planar graphene, vertical graphene can expose a larger effective specific surface area, so that both the basal surface and the edge reaction sites are improved, and the graphene layer is thinned, and the conductivity and light transmittance are also enhanced, and the carbon material itself has high stability, which greatly improves the shielding effect; the vertical graphene layer grows directly on the surface of the semiconductor layer, and the structure is more stable and reliable than bonding and other connection methods. The sheath adopts ceramic fiber and rare earth oxide modified rubber, the instantaneous crosslinking density is increased, the filling of ceramic fiber can further increase the crosslinking density and structural toughness, and finally improves the tensile strength and wind erosion resistance of the invention, so that the sheath of the invention has excellent mechanical properties and corrosion resistance.

[0007] Preferably, the conductive wire comprises a conductive core and a first insulating layer covering the conductive core, and the conductive core is formed by twisting a plurality of first conductors together.

[0008] Preferably, the signal line comprises two signal bodies and an aluminum-plastic composite tape wrapped around the two signal bodies, and each signal body comprises a second conductor located in the middle and a second insulating layer coated outside the second conductor.

[0009] Preferably, the material of the insulating layer includes one or more of polyethylene terephthalate, polyethylene naphthalate, polyether sulfone, polypropylene, polypropylene sulfide, polycarbonate, polyetherimide, polyphenylene sulfide, polyphenylene oxide, polysulfone, and polyphthalamide.

[0010] Preferably, the semiconductor layer is made of graphite foil or graphite cloth.

[0011] Preferably, the total thickness of the wrapped shielding layer is not higher than 5 mm.

[0012] Preferably, the method for preparing the wrapped shielding layer comprises the following steps:

[0013] 1) growing a vertical graphene layer on the surface of the semiconductor layer, and forming a bonding layer on the opposite surface of the semiconductor layer on which the vertical graphene layer is grown;

[0014] 2) when the adhesive layer is not cured or solidified, contacting one side edge of the surface of the flexible insulating layer with the adhesive layer, and placing the flexible insulating layer on the adhesive layer from the edge; and curing the adhesive layer.

[0015] Preferably, in step 1), a plasma in-situ growth method is used to grow a vertical graphene layer on the surface of the semiconductor layer.

[0016] After the graphite foil or graphite cloth is transformed into graphene through allotropy, it obtains optical, electrical and mechanical properties that are superior to those of graphite foil or graphite cloth. In addition, the graphene on the vertical substrate can expose more abundant active sites, and the three-dimensional interconnected structure forms channels that are conducive to ion transmission. The in-situ growth method is used to make the bonding force between the vertical graphene and the semiconductor layer (graphite foil or graphite cloth) stronger. Growing vertical graphene on the semiconductor layer can greatly reduce the thickness of the shielding layer.

[0017] Preferably, the conductor core is formed by twisting a plurality of silver-plated soft copper wires, and the first insulating layer is fluoroplastic.

[0018] Preferably, the method for preparing the material of the sheath comprises:

[0019] S1, mixing thermoplastic elastomer, styrene-butadiene rubber and chlorinated polyethylene at 80-130° C. to obtain mixture 1;

[0020] S2, mixing ceramic fiber, silane coupling agent, butanone, glycerol, EPDM rubber and rare earth oxide at 60-110° C. to obtain mixture 2;

[0021] S3, adding mixture 1 and mixture 2 into an internal mixer, and then adding triisobutyl aluminum, zinc oxide, zinc stearate, and a vulcanizing agent, mixing at 80-130° C., and extruding at 100-135° C. to obtain the sheath material.

[0022] Thermoplastic elastomers have good impact and fatigue resistance, high impact strength and good low-temperature flexibility, maintain good performance when the temperature rises, good resistance to chemicals, oils, solvents and weather, high tear strength and high friction resistance, easy processing and economical, good recyclability; can improve the mechanical strength, heat resistance and weather resistance of the sheath. Styrene-butadiene rubber, its physical structure properties, processing properties and product performance are close to natural rubber, and some properties such as wear resistance, heat resistance, aging resistance and vulcanization speed are better than natural rubber. Chlorinated polyethylene is a polymer synthetic material made by chlorination modification of polyethylene. Its molecules are linear saturated irregular structures, so it has excellent flexibility, heat aging resistance, weather resistance and ozone resistance. Because its molecular structure contains a considerable proportion of chlorine elements, it has good oil resistance, chemical resistance and flame retardancy. EPDM rubber has excellent oxidation resistance, ozone resistance and erosion resistance. Thermoplastic elastomer, styrene-butadiene rubber, chlorinated polyethylene and EPDM rubber are combined to greatly improve the mechanical strength, insulation, heat resistance, weather resistance and corrosion resistance of the resulting sheath.

The special electronic structure of rare earth oxides makes it easy to form complexes. Ceramic fiber and rare earth oxide are combined with the main rubber material through silane coupling agent to enhance the compatibility between ceramic fiber, rare earth oxide and rubber molecules. Rare earth oxide can promote the rapid formation of crystals in rubber molecules, so that the instantaneous crosslinking density of the present invention is increased. The filling of ceramic fiber can further increase the crosslinking density and structural toughness, and finally improve the tensile strength of the present invention; rare earth oxide complexes can also prevent the movement of rubber molecules, combined with the wind erosion resistance of ceramic fiber, so that the sheath of the present invention has excellent mechanical properties and corrosion resistance. Using cyanopropyl zirconium metallocene chloride-methyl aluminum oxide composite catalyst, zinc oxide, zinc stearate, and vulcanizing agent as the vulcanization system, the crosslinking density of the present invention is enhanced, and the aging resistance, insulation performance and mechanical properties of the resulting sheath are greatly improved.

[0025] Preferably, the material of the sheath includes the following raw materials in parts by weight: 15-25 parts of thermoplastic elastomer, 15-25 parts of styrene-butadiene rubber, 25-45 parts of chlorinated polyethylene, 2-6 parts of dibenzoyl peroxide, 15-25 parts of ceramic fiber, 10-15 parts of silane coupling agent, 3-6 parts of butanone, 4-8 parts of glycerol, 25-45 parts of ethylene propylene diene rubber, 15-25 parts of rare earth oxide, 3-10 parts of cyanopropionyl zirconium metallocene chloride-methylaluminum oxide composite catalyst, 3-10 parts of zinc oxide, 1-5 parts of zinc stearate, and 8-15 parts of vulcanizing agent.

[0026] Preferably, the rare earth oxide is cerium oxide and / or lanthanum oxide.

[0027] The present invention can achieve at least one of the following beneficial effects:

[0028] The present invention adopts a central symmetrical structure in structural design, which not only has the advantages of small outer diameter, light weight, good bending performance and stable product structure, but also has excellent electrical performance, which is conducive to transportation and installation; a reinforcing core is arranged in the center, which improves the structural strength and service life of the integrated cable.

The sheath is made of ceramic fiber and rare earth oxide modified rubber, which instantly increases the crosslinking density. The filling of ceramic fiber can further increase the crosslinking density and structural toughness, and ultimately improve the tensile strength and wind erosion resistance, so that the sheath has excellent mechanical properties, flame retardant properties and corrosion resistance.
