Abstract
A water-blocking cable belongs to the technical field of cables, comprises a cable core and an outer protective layer, and is characterized in that the cable core is formed by stranding insulated wires and water-blocking fillers, the cable core is wrapped by an aluminium foil shielding layer, a PVDC (Polyvinyl Dichloride) protective film and the outer protective layer are extruded and wrapped on the aluminium foil shielding layer by adopting a coextrusion technology, and the thickness of the PVDC protective film is 0.1mm to 0.2mm. The water-blocking cable provided by the utility model has a scientific, novel and reasonable structure, an advanced and simple technology, low cost and a good bending property, is easy to produce and manufacture, has oxygen resistance and transparency under the condition of high humidity, is not easy to fracture and has good extensibility during transportation and carrying, has an attractive printing effect without ink removal, and has resistance to oil, organic solvents and corrosion.
Description
Technical field
The utility model relates to a kind of cable, and especially a kind of novel cable that blocks water belongs to the cable technology field.
Background technology
The cable that blocks water of Shi Yonging adopts radially that waterproof construction mostly is the APL aluminum plastic laminate sheath in the market, and general employing of the coating mode of plastic-aluminum band indulged pack arrangement, so protective coverings of cable adopts pe sheath and its bonding more, for be exactly the slit of putting up that solves the vertical packet generation of plastic-aluminum, and jacket thickness is nearly to more than the 1.4mm.Such cable construction cost height, bending property are lower, so need on the market that a kind of production cost is low, the novel cable that blocks water of good bending property.
The utility model content
The purpose of this utility model is exactly for satisfying the needs in market, a kind of novel cable that blocks water being provided.
The purpose of this utility model is to realize like this; a kind of cable that blocks water; comprise cable core and outer jacket; it is characterized in that described cable core is by insulated wire with the waterproofing type filler is stranded forms; wrapped foil shielding layer on described cable core; adopt coextrusion processes to extrude PVDC diaphragm and outer jacket on foil shielding layer, described PVDC diaphragm thickness is 0.1mm-0.2mm.
Described insulated wire constitutes for extrude flame-retardant crosslinking polyethylene insulated layer on the brass twisted wire conductor that meets the GB/T14954 regulation.
Described outer sheath material is Halogen cable jacket material or flame-proof cable sheath material or Oil-Resistant Cable Sheath or organic solvent-resistant cable jacket material or corrosion proof cable protective cover material.
The utility model scientific structure is new reasonable, and technology is advanced simple, manufactures easily, and cost is low, and serviceability is good.The utility model adopts PVDC cast film technology, increases one deck PVDC diaphragm on cable core.PVDC, formal name used at school are " polyvinylidene chloride ".It is a kind of nonpoisonous and tasteless, safe and reliable high barrier material.Except that general performance with plastics, also have oil resistance, corrosion resistance and excellent protection against the tide, mildew-resistant, also have the superior printing characteristics energy simultaneously.PVDC has linear polymerization chain structure from beginning to end: ...-CH2-CCl2-CH2-CCl2-... because the symmetry of its molecular structure, and intermolecular cohesive force is strong, oxygen molecule, hydrone are difficult in the PVDC molecule and move, and high-crystallinity and high density have determined that the PVDC copolymer has good oxygen barrier, gas barrier properties.Performances such as the protection against the tide of the oil resistance of application PVDC, corrosion resistance and excellence, mildew-resistant replace the waterproof technology structure of the APL aluminum plastic laminate sheath of traditional cable, thereby reduced cost on the structures of water-proof cable, have increased the diversity of cable processing.
The utility model adopts the wrapped shielding mode of aluminium foil to replace the cable shield structure that blocks water of traditional plastic-aluminum shielding, increases bending property.The bending property of the construction of cable of the vertical bag shielding of existing product employing plastic-aluminum band is lower, and needs professional vertical bag equipment, so have the limitation on the equipment, this product adopts the wrapped shielding of aluminium foil, just can operate on common cabler.
The utility model adopts PVDC and protective layer cable material coextrusion processes, and thickness 0.1mm-0.2mmPVDC diaphragm and protective coverings of cable are extruded jointly.Compare with traditional APL aluminum plastic laminate sheath, the bending property of this product is higher, and the outside diameter of cable is compared less with existing product.
The utility model has solved the limitation of polyethylene sheathing material bonding, present cable instructions for use improves constantly, but there is the limitation of many purposes aspect in polyethylene, and other materials such as that this product can be selected is fire-retardant, Halogen, winter protection, oil resistant reach the structure of multiple instructions for use coexistence.
This product has following characteristic: resistance oxygen, the transparency under the high humidity, transport, carry not frangibility, and ductility is good, and printing effect is attractive in appearance and do not fall China ink, oil resistant, organic solvent-resistant, corrosion-resistant.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-insulated wire, 2-filler, 3-foil shielding layer, 4-PVDC diaphragm, 5-outer jacket.
Embodiment
On the brass twisted wire conductor that meets the GB/T14954 regulation, extrude flame-retardant crosslinking polyethylene insulated layer and constitute insulated wire.Insulated wire and waterproofing type filler are twisted into cable core, and wrapped foil shielding layer on cable core adopts PVDC and outer jacket cable material coextrusion processes to extrude PVDC diaphragm and outer jacket on foil shielding layer.The thickness of PVDC diaphragm is 0.1mm-0.2mm, and outer sheath material is Halogen cable jacket material or flame-proof cable sheath material or Oil-Resistant Cable Sheath or organic solvent-resistant cable jacket material or corrosion proof cable protective cover material or has simultaneously and be Halogen, fire-retardant, oil resistant, organic solvent-resistant and corrosion resistant cable jacket material.
