Description
Technical field
The present invention relates to a kind of cross-linked computer cable and manufacture method thereof, especially relate to a kind of 150 ℃ of irradiation cross-linked computer cables and manufacture method thereof.
Background technology
In the prior art, domestic computer cable generally adopts the polyvinyl chloride insulation data cable, and this kind polyvinyl chloride insulation data cable, low because of its temperature resistant grade low (70～90 ℃), ampacity, easily aging, easy to crack, dielectric loss is big, poison exponent is high and defective such as environmental-protecting performance difference, on the application and the scope of application, be restricted.At present, European Union, the U.S., Japan and other countries are more and more higher to the requirement of producing cable product, and have formulated corresponding legal norm; For example, require computer cable not contain halogen, do not produce pernicious gas and corrosive gas.And existing polyvinyl chloride insulation data cable can not adapt to this needs, and in addition, the temperature resistant grade of polyethylene insulation is low, and is when the higher occasion of some long-term work temperature, more inapplicable.For addressing this is that, the researcher works out by crosslinked polyetylene insulated computer cable and substitutes traditional polyvinyl chloride insulation data cable.
Produce the crosslinked method of cable and mainly contain two kinds: be i.e. chemical crosslinking and physical crosslinking.Chemical crosslinking is divided into dry cross-linking and warm water crosslinking again.Dry cross-linking is to reach in 300-400 ℃ the gases at high pressure in temperature to make the sub polyethylene subchain crosslinked through regular hour property.Warm water crosslinking is that cable is dipped in 90 ℃ warm bubbly water 5-7 hour, makes the sub polyethylene subchain crosslinked.Physical crosslinking claims cross-linking radiation again, the high-energy electron line that promptly utilizes electron accelerator to launch, bombardment cable insulation or restrictive coating, macromolecular chain is interrupted, first point that is interrupted is called free radical, because of the free radical instability, will reconfigure each other, reconfigure the back and become three-dimensional netted molecular structure by original chain molecule structure and form crosslinkedly, this cross-linking method can not influence the anti-flammability and the electric property of cable.
General crosslinked data cable generally all is the chemical crosslinking control cable both at home and abroad, and its temperature grade only is 90 ℃.So the higher control system of temperature resistant grade generally adopts silicon rubber and fluoroplastics data cable.Silicon rubber is higher because of its price, processing technology is complicated, mechanical strength is low, insulation property and tear resistance are poor, has greatly limited its application on control cable; Fluoroplastics are used also not extensive because of shortcomings such as it costs an arm and a leg, the processing technology complexity, and are easy to crack at present.
Summary of the invention
Technical problem to be solved by this invention: be that a kind of temperature resistant grade that provides reaches the manufacture method of 150 ℃ computer cable and this computer cable in order to overcome the weak point that the dynamo-electric cable of aforementioned calculation exists.
The present invention is achieved in that a kind of 150 ℃ of irradiation cross-linked computer cables for solving the problems of the technologies described above its technical scheme, contain outer jacket 1, first screen 2, first belting layer 3, filling 4 and interior envelope curve 5, it is characterized in that: wherein be first screen 2 in the outer jacket 1, be that first belting layer, 3, the first belting layers 3 contain above-mentioned several interior envelope curves 5 in first screen 2; In the middle of the interior envelope curve 5 and first belting layer 3, be filling 4;
