Abstract
The present invention relates to a method for manufacturing a high-temperature resistant superthin conductor and a product thereof. The present invention comprises: polyethylene(100), crosslinking agents 1, 3-double (tert-butyl peroxy isopropyl) benzene (5 to 10), flame retardant (20 to 50), antioxidant (5 to 10) and light stabilizing agents three (1, 2, 2', 6, 6'-pentamethyl piperidino) phosphorous (5 to 20) are adopted, and are mixed and granulated, so that the insulation layer of the conductor is made; then, irradiation crosslinking processing is carried out to the insulating layer of the conductor by using an electron accelerator. The conductor made by the method of the present invention can work under the condition of high a temperature of 150 DEG C for a long time, and has the advantages of oil resistance, flame resistance, wear resistance and softness.
Description
Technical field
The present invention relates to a kind of manufacture method of high temperature resistant ultra-thin lead.
Background technology
At present, the long-term work temperature of ultra-thin lead mostly is no more than 130 ℃, and the ambroin layer that surpasses this temperature lead is often very fast aging, even on fire.Thereby limited the load of lead.If want by bigger load, that has only the metal-cored cross section of increase lead, wire diameter is increased and the weight increase, thereby causes the wiring space increase and influence the long-term use of lead etc.
Summary of the invention
The objective of the invention is to improve the shortcoming of prior art, and a kind of manufacture method and product of high temperature resistant ultra-thin lead are provided.
For achieving the above object, the present invention takes following design: at first, the insulating barrier of ultra-thin lead is by the weight components mixing granulation, and extrudes and make,
Polyethylene 100
Crosslinking agent 1, two (t-butyl peroxy isopropyl) the benzene 5-10 of 3-
Fire retardant 20-50
Antioxidant 5-10
The inferior phosphorus 5-20 of light stabilizer three (1,2,2 ', 6,6 '-pentamethyl piperidyl)
Secondly, making line metal wire drawing, twisted wire and making lead by ultra-thin insulating barrier expressing technique with above-mentioned particle;
In the 3rd step, with electron accelerator the described wire insulation of making is carried out cross-linking radiation and handle irradiation dose 50-250kGy, irradiation energy: 0.5-3.0Mev, radiation mode: parallel " 8 word " mode technology or intersection " 8 word " mode technology.
The wire insulation made from above-mentioned material carries out after cross-linking radiation handles through electron accelerator, and variation has taken place its insulating barrier molecular structure, and the long-term work temperature that can improve lead is at 150 ℃.The lead of making as stated above can be at the ultra-thin expressing technique system one deck of insulating barrier external application restrictive coating the same with insulating material as needs, and it also carries out the electron accelerator irradiation crosslinking Treatment with insulating barrier.Certainly after insulating barrier carries out the cross-linking radiation processing with electron accelerator, also available ultra-thin expressing technique system one deck fluoroplastics restrictive coating.In above-mentioned granulation component, what crosslinking agent was selected for use is 1, two (t-butyl peroxy isopropyl) benzene of 3-; Fire retardant is available to be aluminium hydroxide, magnesium hydroxide or deca-BDE; The neat agent of antioxygen is available to be: four-(4-hydroxyl-3,5-t-butyl-phenyl propionic acid) pentaerythritol ester (antioxidant 1010), 3,5-di-tert-butyl-4 monohydroxy benzenpropanoic acid octadecyl ester (antioxidant 1076), 1,1,3-three (second-methyl-4 hydroxyls-5-t-butyl-phenyl) butane (antioxidant CA); What light stabilizer was selected for use is the inferior phosphorus in three (1,2,2 ', 6,6 '-pentamethyl piperidyl).
The thickness of the cladding that wire insulation made from the inventive method or insulating barrier constitute with sheath between 0.1mm-0.8mm, but long-term work under 150 ℃ hot conditions, its mechanical performance is:
Tensile strength 〉=10 MPas before insulating barrier is aging,
Elongation at break 〉=150% before insulating barrier is aging.
Wore out 168 hours through air-oven, 178 ℃ ± 2 ℃ of aging temperatures, aging front and back tensile strength rate of change≤± 30%,
Elongation at break rate of change≤± 30% before and after aging.
Product of the present invention is oil resistant, fire-retardant, wear-resisting, soft also.
