Abstract
The utility model belongs to the field of wires and cables and especially relates to a halogen-free crosslinked cable. The halogen-free crosslinking cable comprises a conductor and a crosslinked insulating layer. An EVA resin layer is arranged on the crosslinked insulating layer. The crosslinked insulating layer and the EVA resin layer are bonded through polyimide thermosetting resin. A flame-retarding layer is arranged on the EVA resin layer. The material of the flame-retarding layer is synthetic rubber. The EVA resin layer and the flame-retarding layer are bonded through moistureproof adhesive. With the above structure, the halogen-free crosslinked cable is improved on the basis of a conventional halogen-free crosslinked cable; and through the effect of the EVA resin layer, the defects on the aspects of elasticity, flexibility, glossiness and gas permeability of the crosslinked insulating layer 2 are compensated.
Description
Technical field
The utility model belongs to electric wire field, particularly the crosslinked line of a kind of Halogen.
Background technology
Radiation electric wire is radiated crosslinking PVC (Polyvinyl Chloride) and the crosslinking with radiation PE general designation as the electric wire of insulator, and PVC and PE have outstanding electrical characteristic, mechanical property, and chemical proofing, and more cheap in price, be therefore widely used.Their weakness is to meet high temperature after-tack, merges, deforms, but after PVC, PE is crosslinked, molecular structure becomes three integrated structures, even if temperature rise also can not be melted above, flow to fusing point, non-radiating.
Electric wire refers to the material for electric power, communication and associated transport purposes.Along with the continuous expansion of the industry sizes such as power industry, data communication industry, urban track traffic industry, car industry and shipbuilding industry, also will increase rapidly the demand of electric wire, following electric wire also also has huge development potentiality, through research, these development potentialities are cable further to promote in anti-flammability, the performance such as anti-aging, thereby adapt to the use under various conditions.
Summary of the invention
The technical problem to be solved in the present invention is to provide the crosslinked line of a kind of Halogen, and the crosslinked line of this Halogen, on the basis of existing crosslinked line, has further raising in anti-flammability, elasticity, flexibility, glossiness, gas permeability.
For solving the problems of the technologies described above, the utility model provides a kind of Halogen to be cross-linked line, comprises conductor and cross linked insulation layer; Described cross linked insulation layer is provided with EVA resin bed, and cross linked insulation layer and EVA resin bed bind by polyimides thermosetting resin; Described EVA resin bed is provided with flame-retardant layer, and the material of flame-retardant layer is synthetic rubber, between EVA resin bed and described flame-retardant layer, is provided with moistureproof bonding coat.
Further, described moistureproof bonding coat is melamine resin adhesive.
Further, between described flame-retardant layer and EVA resin bed, be provided with radiation protective layer, described radiation protective layer is copper nickel ion coating.
Further, the thickness of described flame-retardant layer is 80-110nm.
The beneficial effect of the crosslinked line of a kind of Halogen of the present utility model is, on the basis of the crosslinked line of existing Halogen, improves, and by the effect of EVA resin bed, has made up the deficiency of cross linked insulation layer 2 in elasticity, flexibility, glossiness, gas permeability.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model structure.
In figure, 1 is conductor, and 2 is cross linked insulation layer, and 3 is EVA resin bed, and 4 is flame-retardant layer, and 5 is radiation protective layer
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of Halogen is cross-linked line, comprises conductor 1 and cross linked insulation layer 2; And the cross linked insulation layer 2 that the utility model Halogen is cross-linked in line is PE cross-linked layer, described cross linked insulation layer 2 is provided with EVA resin bed 3, cross linked insulation layer 2 binds by polyimides thermosetting resin with EVA resin bed 3, polyimides has high temperature resistant, corrosion-resistant and good electrical property, when ensureing bonding effect, can also ensure the use of cable under high temperature, perishable condition; Described EVA resin bed 3 is provided with flame-retardant layer 4, the material of flame-retardant layer 4 is synthetic rubber, synthetic rubber has good shock resistance and anti-fatigue performance, high impact and good low temperature flexibility, when temperature rise, keep good performance, both possessed the high resiliency of traditional cross-linking vulcanized rubber, ageing-resistant, the every excellent properties of oil resistance, possessed again the feature that common plastics is easy to process, processing mode is wide, and can cut down finished cost simultaneously.Between EVA resin bed 3 and described flame-retardant layer 4, be provided with moistureproof bonding coat, in the present embodiment, described moistureproof bonding coat is melamine resin adhesive.
The content of the vinyl acetate in EVA resin bed 2 is lower than 20%, and the EVA resin bed of this sample ingredient has good resistance to low temperature, the chemicals corrosion such as sea water resistance, grease, acid, alkali, antibacterial, nontoxic, tasteless, pollution-free, be easy to carry out hot pressing, cut out, the processing such as gluing, laminating, also there is obvious impact toughness and environmental stress crack resistance, made up the deficiency of cross linked insulation layer 2 in elasticity, flexibility, glossiness, gas permeability.
Further, between described flame-retardant layer 4 and EVA resin bed 3, be provided with radiation protective layer 5, described radiation protective layer 5 is copper nickel ion coating, the advantage that radiation protective layer 5 arranges is, reduced in cable use procedure, internal flow radiation to external world, has ensured long-term user's health.
In the present embodiment, the thickness of described flame-retardant layer 4 is 80-110nm, and such size can farthest be protected cable.
It should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
