Abstract
The invention discloses an electric wire radiation crosslinking technology. First, copper wires are drawn by a wire drawing machine to a required width and moved to a wire wrapping machine via a guide rail, and a conductor composed of the copper wires is coated with rubber to form a complete electric wire; then, electron beam irradiation is performed on the electric wire by an electron accelerator, and sensitizer is added in the process of irradiation; and finally, the electric wire after irradiation is post-processed. The insulating layer of the electric wire is bombarded by high-energy electron beams produced by the electron accelerator to break a polymer chain, and a recombined chain molecular structure is changed into a three-dimensional meshed molecular structure which is difficult to catch fire, can prevent or delay flame spread, has large overhead and high insulation resistance, and is environment-friendly and safe. Complex operation of a traditional production technology is avoided, and the production cost is reduced.
Description
Technical field
The present invention relates to electric wire production field, particularly relate to a kind of electronics and add the electric wire production technology of restrainting device and wire surface being processed.
Background technology
Electric wire is a kind of instrument common in life, for all electronic device field, traditional handicraft produces electric wire to improve its performance, such as: ampacity, insulated electro are resistive, useful life, Environmental Safety etc., need a large amount of technique to be used for ensureing the raising of above-mentioned performance, not only troublesome poeration, and input cost is comparatively large, and be not suitable for medium-sized and small enterprises, therefore, in order to solve electric wire complex production process, the problem that input cost is large seems particularly important.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of electric wire crosslinking with radiation technique, by carrying out electron accelerator process to the surface of electric wire, can greatly save other production technologies, to solve current electric wire complex production process, the problem that production cost is large.
In order to solve the problem, the invention provides a kind of electric wire crosslinking with radiation technique, first by wire drawing machine to copper cash wire drawing to required width, via guide rail, copper cash is moved on wire lapping machine again, rubber coated is carried out to the conductor that copper cash is formed, to form complete electric wire, then adds with electronics bundle device to carry out electron beam irradiation to electric wire, and in irradiation process, add sensitizer, finally again reprocessing is carried out to the electric wire after irradiation.
Further improvement is: described electric wire irradiation dose is at 10-20Mrad.
Further improvement is: described reprocessing includes high-temperature process, is moved to by electric wire in hot room, in hot room, be filled with nitrogen, and the temperature of described hot room remains on 150-200C °, and the processing time remains on 20-40min.
Further improvement is: the energy that described electronics adds bundle device remains on 2-4MeV, and line remains on 5-15MA.
The invention has the beneficial effects as follows: by the high-energy electron line bombardment electric wire insulation layer utilizing electronics to add the generation of bundle device, macromolecular chain is interrupted, the chain-like molecular structure reconfigured becomes three-dimensional netted molecular structure, there is the ability being difficult to catch fire and stop or delay propagation of flame, and overload quantity is large, insulation resistance large, Environmental Safety, eliminate the troublesome operation of traditional processing technology, reduce Productive statistics cost.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with execution mode, the invention will be further described, and present embodiment only for explaining invention, does not form limiting the scope of the present invention.
Present embodiments provide a kind of electric wire crosslinking with radiation technique, first by wire drawing machine to copper cash wire drawing to required width, via guide rail, copper cash is moved on wire lapping machine again, rubber coated is carried out to the conductor that copper cash is formed, to form complete electric wire, add with electronics bundle device to carry out electron beam irradiation to electric wire again, and add sensitizer in irradiation process, finally again reprocessing is carried out to the electric wire after irradiation.Described electric wire irradiation dose is at 10-20Mrad.Described reprocessing includes high-temperature process, is moved to by electric wire in hot room, in hot room, be filled with nitrogen, and the temperature of described hot room remains on 150-200C °, and the processing time remains on 20-40min.The energy that described electronics adds bundle device remains on 2-4MeV, and line remains on 5-15MA.Electronics is utilized to add the high-energy electron line bombardment electric wire insulation layer of bundle device generation, macromolecular chain is interrupted, the chain-like molecular structure reconfigured becomes three-dimensional netted molecular structure, there is the ability being difficult to catch fire and stop or delay propagation of flame, and overload quantity is large, insulation resistance large, Environmental Safety, eliminate the troublesome operation of traditional processing technology, reduce Productive statistics cost.
