Abstract
The utility model discloses an anti-flaming environment-friendly wire including a conductor. An insulation layer wraps the outer surface of the conductor in an extruded manner. The insulation layer is composed of an inner insulation layer and an outer insulation layer. The inner insulation layer is formed by processing irradiation crosslinking polyolefin material while the outer insulation layer is formed by processing low-smoke halogen-free anti-flaming irradiation crosslinking polyolefin material. The double-layer insulation layer of the anti-flaming environment-friendly wire provided by the utility model is formed in a single process through co-extrusion of the two irradiation crosslinking polyolefin materials with good compatibility and mutually-complementary properties by utilizing a concentric mold. The inner insulation layer has good mechanical, electrical and high-and-low temperature resisting properties while the outer insulation layer has good mechanical properties and low-smoke, halegon-free and anti-flaming performance, so that a problem that good insulation performance and anti-flaming performance cannot be realized at the same time is solved. In the meantime, since the double-layer insulation layer goes through an irradiation crosslinking link after being manufactured by adopting a concentric mold double-layer co-extrusion system, so that the integrality, quality uniformity and high efficiency of the double-layer insulation layer are guaranteed. The double-layer insulation layer of the anti-flaming environment-friendly wire provided by the utility model is reasonable in structure and comparatively high in cost performance, and is high-and-low temperature resisting, low-smoke, halogen-free and anti-flaming, so that the double-layer insulation layer of the anti-flaming environment-friendly wire has good social value and market prospect and is worthy of promotion.
Description
Technical field:
The utility model relates to a kind of electric wire, particularly relates to a kind of high-flame-resistance environment-friendly electric wire, is applicable to rated voltage 450/750V and following building, electrical equipment, the switch equal power device system that has low cigarette, Halogen, fire-retardant, environmental protection etc. to require.
Background technology:
Apparent in view advantage is arranged on processing characteristics, cost performance due to pvc material, thereby be widely used in electric wire.But there is following defect in pvc material: pvc material easily water suction causes insulating breakdown; Pvc material contains a large amount of halogens, and decomposition temperature is low, resistance to elevated temperatures is poor, can discharge a large amount of poisonous corrosive gas and dense smoke during burning, causes " secondary disaster ".Once as the high-rise breaking out of fire, common polyvinyl chloride (PVC) electric wire can be extended to the intensity of a fire all devices of connection, the every nook and cranny of building, produce a large amount of toxic smogs simultaneously, increased the loss of fire, and bring difficulty to rescue work, so a kind of low cigarette of developmental research, Halogen, electric wire fire-retardant, environment-friendly type are particularly important.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of rational in infrastructure, high-low temperature resistant, low cigarette, Halogen, high flame retardant and the higher high-flame-resistance environment-friendly electric wire of cost performance are provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of high-flame-resistance environment-friendly electric wire, comprise conductor, described conductor outer surface is extruded with insulating barrier, described insulating barrier is comprised of inner insulating layer and external insulation layer, wherein: described inner insulating layer is processed by the cross-linking radiation polyolefine material, and described external insulation layer is processed by low-smoke non-halogen flame-retardant cross-linking radiation polyolefine material.
Described conductor is closed and is formed by single or many soft copper skein silks.
Described inner insulating layer and external insulation layer double-layer coextrusion are made the irradiation crosslinked polyolefin insulating layer by irradiation processing.
Positive beneficial effect of the present utility model is as follows:
1, inner insulating layer of the present utility model and external insulation layer adopt that two kinds of compatibilities are good, performance has the complementary disposable machine-shaping of the concentric mould double-layer coextrusion of cross-linking radiation polyolefine material utilization.Inner insulating layer possesses good machinery, electric and high and low temperature resistance, and external insulation layer has excellent mechanical performance, low cigarette, Halogen, high flame resistance, has solved the difficult problem that insulation property and high flame retardant can be taken into account; Simultaneously due to this double insulating layer, carry out cross-linking radiation after adopting the manufacture of concentric mould double-layer coextrusion system of processing, guaranteed the one, homogeneous of two insulation and quality requirement efficiently.
2, insulating barrier of the present utility model adopts polyolefine material to process, and does not produce the characteristics of corrosive gas while having high temperature tolerance, low smokiness, visual range length, burning.After cross-linking radiation processing, make the polyolefin linear polymeric structure be transformed into three-dimensional netted molecule crosslinked structure, the heatproof degree rises to 125～150 ℃ from 80～90 ℃.
3, insulating barrier of the present utility model adopts after concentric mould double-layer coextrusion and carries out cross-linking radiation and process, when enhancing product performance, make again the insulation thickness of equivalents reduce (comparing with polyvinyl chloride (PVC) electric wire), save national resources, improved the cost performance of product.
4, anti-overload ability of the present utility model is strong, electrical property aspect current-carrying large (than common polyvinyl chloride (PVC) electric wire, promoting 20～40%).
5, the utlity model has excellent fire resistance, can pass through the single testing vertical flammability of electric wire category-A.
6, the utility model mechanical and physical performance is stable, anti-aging, corrosion-resistant, good environmental protection.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Referring to Fig. 1, a kind of high-flame-resistance environment-friendly electric wire, comprise conductor 1, conductor 1 outer surface is extruded with insulating barrier, insulating barrier is comprised of inner insulating layer 2 and external insulation layer 3, wherein: conductor 1 is closed and is formed by single or many soft copper skein silks, and inner insulating layer 2 is processed by the cross-linking radiation polyolefine material, and external insulation layer 3 is processed by low-smoke non-halogen flame-retardant cross-linking radiation polyolefine material; Inner insulating layer 2 and external insulation layer 3 double-layer coextrusions are made the irradiation crosslinked polyolefin insulating layer by irradiation processing.
