Abstract
The utility model discloses a two-layer co-extruded ultraviolet light crosslinked wire which is characterized in that the two-layer co-extruded ultraviolet light crosslinked wire comprises a copper conductor (1) at an innermost layer, an inner insulating layer (2) which is extruded outside the copper conductor and is made of high density materials, and an outer insulating layer (3) which is extruded outside the inner insulating layer and is made of ultraviolet light crosslinked high flame retardant materials. Ultraviolet light is employed as a media by the wire with the above structure, the insulating materials are crosslinked under a light environment, thus a service life and a degree of heat resistance of the product are increased, there is no residue of toxic and harmful substances, ecological environmental protection is facilitated, insulation performance is good in a warm and wet environment, bending performance is good, and wiring requirements under various environments can be satisfied.
Description
Technical field
The utility model relates to a kind of electric wire, and especially a kind of life-span is long, is conducive to a kind of electric wire of ecological, environmental protective.
Background technology
At present, the electric wire that extensively adopts in the house decoration is generally the PVC material, and major defect is that its life-span is short, and fire resistance is not good, produce poisonous and hazardous gas after the burning, and the insulation property under warm and humid environment is relatively poor.The material of general wire insulation adopts the mode of cross-linking reaction to increase the life-span of electric wire; prior art generally adopts electron irradiation crosslinked, and electron irradiation is crosslinked higher radiation source is arranged, and can stay by Disabled in material; thereby environment and the person are impacted, be unfavorable for ecological environmental protection.The present invention therefore.
Summary of the invention
The utility model purpose is to provide a kind of life-span long, is conducive to a kind of electric wire of ecological, environmental protective.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
A kind of two layers of co-extrusion ultraviolet light cross-linking electric wire is characterized in that it comprises:
The copper conductor of innermost layer (1);
Extrude the inner insulating layer (2) outside this copper conductor, this inner insulating layer (2) adopts high density material to make;
And extruding external insulation layer (3) outside this inner insulating layer, this external insulation layer (3) adopts the high flame retardant material of ultraviolet light cross-linking to make;
Further, the high density material that described inner insulating layer (2) adopts is polyphenylene oxygen PPO, and Main Ingredients and Appearance is the oxidative condensation material of phenylate and xylenol.
Further, the high flame retardant material of the ultraviolet light cross-linking that described external insulation layer (3) adopts is low smoke and zero halogen LSNH, and Main Ingredients and Appearance is the intermingling material of polyethylene, inorganic matter fire retardant and photosensitizer.
Than solution of the prior art, the utility model advantage is:
1. the utility model adopts ultraviolet light as medium exactly, it is crosslinked to allow Insulation Material carry out under luminous environment, thereby increase life of product and temperature resistant grade, ultraviolet light can not be stayed in the material by Disabled when cross-linking reaction occured, can not produce any impact to environment and the person yet, thereby be conducive to ecological, environmental protective.
2. the utility model is that low-smoke non-halogen flame-retardant is crosslinked, do not contain any in the world with the explicitly provided poisonous and harmful substance of China;
3. consider the suction problem of fire proofing, so inner insulating layer adopts high density utmost point low water absorbable manufacture of materials, but the insulation property of Effective Raise electric wire under warm and humid environment.
4. external insulation layer adopts the high flame retardant manufacture of materials, carries out simultaneously the crosslinked anti-wear performance that increased, cracky not when poling.
Because above-mentioned advantage, the crosslinked series products of the alternative electron irradiation of the utility model, and can replace the PVC electric wire that uses in the house decoration, thereby solved common PVC electric wire life-span weak point comprehensively, can produce the series of problems such as toxic and harmful during burning, also can be used for connecting in all kinds of electrical equipments, also solved the problem that the electron irradiation series products exists irradiation Disabled picture to ring environment simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the cutaway view of two layers of co-extrusion ultraviolet light cross-linking of the utility model electric wire.
Wherein: 1 is copper conductor; 2 is inner insulating layer; 3 is external insulation layer.
Embodiment
Below in conjunction with specific embodiment such scheme is described further.Should be understood that these embodiment are not limited to limit the scope of the invention for explanation the present invention.The implementation condition that adopts among the embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in the normal experiment.
Embodiment
As shown in Figure 1, a kind of two layers of co-extrusion ultraviolet light cross-linking electric wire, structure is as follows:
The copper conductor 1 of innermost layer;
Extrude the inner insulating layer 2 outside this copper conductor, this inner insulating layer 2 adopts high density material to make; This high density material is polyphenylene oxygen PPO, and Main Ingredients and Appearance is the oxidative condensation material of phenylate and xylenol.
And extruding external insulation layer 3 outside this inner insulating layer, this external insulation layer 3 adopts the high flame retardant material of ultraviolet light cross-linkings to make; This high flame retardant material is low smoke and zero halogen LSNH, and Main Ingredients and Appearance is the intermingling material of polyethylene, inorganic matter fire retardant and photosensitizer
The electric wire of said structure adopts ultraviolet light as medium, it is crosslinked to allow Insulation Material carry out under luminous environment, thereby increase life of product and temperature resistant grade, not residual poisonous and hazardous material, be conducive to ecological, environmental protective, and under warm and humid environment good insulation preformance, the good cabling requirement that can satisfy under the various environment of bending property.
Above-mentioned example only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalent transformations that Spirit Essence is done according to the present invention or modification all should be encompassed within protection scope of the present invention
