Description
Technical field
The present invention relates to submarine cable fields, more particularly to a kind of preparation method of waterproof submarine cable.
Background technology
Water proofing property is a key factor of submarine cable long-term reliability operation.Submarine cable on the one hand will be by seawater
Erosion, on the other hand to prevent the attachment of marine organisms.The marine organisms being attached on submarine cable can secrete corrosive goods
Matter destroys the sheath of submarine cable, causes the damage of submarine cable.Existing various submarine cable, water resistance still have
Certain limitation needs to further increase.
Invention content
The invention mainly solves the technical problem of providing a kind of preparation methods of waterproof submarine cable, can significantly improve
With improvement water resistance, the service life of submarine cable is improved.
In order to solve the above technical problems, one aspect of the present invention is：A kind of waterproof submarine cable is provided
Preparation method includes the following steps：
（1）Wire drawing process is carried out to conductor；
（2）By step（1）Conductor after middle wire drawing is passed in PBT protecting pipes；
（3）Using injection pump to step（2）In protecting pipe in gap squeeze into inhale hydrogen filler, formed core；
（4）By vertical cross-linked production line to step（3）In core carry out insulation and insulation shielding coextrusion process, and
It is wrapped that vertical cross-linked production line outlet carries out the first waterproof layer spiral；
（5）By step（4）Material after middle outlet is after deaeration chamber degassing, through continuous extruder cladding copper strip, and even
It is wrapped that continuous extruder outlet carries out the second waterproof layer spiral；
（6）By step（5）In the material of wrapped second waterproof layer enter wire armoring machine, carry out wire armoring, and coat
Anti-corrosion asphalt；
（7）Again to sheathing is completed on extrusion molding production line, the waterproof submarine cable is obtained.
In a preferred embodiment of the present invention, the degassing time is 6~8 days, and temperature is 85~90 DEG C.
In a preferred embodiment of the present invention, the step（3）In, the loading for inhaling hydrogen filler accounts for the PBT
The 75~90% of gap between pipe and conductor.
In a preferred embodiment of the present invention, the thickness ratio of first waterproof layer and the second waterproof layer is 1：1~2.
The beneficial effects of the invention are as follows：A kind of preparation method of waterproof submarine cable of the present invention is easy, easy to implement, leads to
The design for crossing two layers of water-proof system effectively improves the water resistance of submarine cable, meets submarine cable of new generation and is protected to waterproof
The requirement of shield, wide market.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below so that advantages and features of the invention can be easier to by
It will be appreciated by those skilled in the art that so as to make a clearer definition of the protection scope of the present invention.
The embodiment of the present invention includes：
A kind of preparation method of waterproof submarine cable, includes the following steps：
（1）Wire drawing process is carried out to conductor；
（2）By step（1）Conductor after middle wire drawing is passed in PBT protecting pipes；
（3）Using injection pump to step（2）In protecting pipe in gap squeeze into inhale hydrogen filler, formed core；The suction
The loading of hydrogen filler accounts for 75~90% of gap between the PBT pipes and conductor；The suction hydrogen filler is mainly to be by mass fraction
60~80 parts of poly-a-olefin oil, 20~40 parts of molecular sieve and 10~20 parts of SBR emulsion are mixed with, to catch
Catch the hydrogen for being present in conductor gap；
（4）By vertical cross-linked production line to step（3）In core carry out insulation and insulation shielding coextrusion process, and
It is wrapped that vertical cross-linked production line outlet carries out the first waterproof layer spiral；
（5）By step（4）Material after middle outlet is after deaeration chamber degassing, through continuous extruder cladding copper strip, and even
It is wrapped that continuous extruder outlet carries out the second waterproof layer spiral；The degassing time is 6~8 days, and temperature is 85~90 DEG C；
（6）By step（5）In the material of wrapped second waterproof layer enter wire armoring machine, carry out wire armoring, and coat
Anti-corrosion asphalt；
（7）Again to sheathing is completed on extrusion molding production line, the waterproof submarine cable is obtained.
The thickness ratio for the first waterproof layer and the second waterproof layer that the above method obtains is 1：1~2, and the material of two waterproof layers
Identical, main component is that mass fraction is 60 parts of epoxy group rubber oils, 20 parts of silvalins, 10 parts of epoxy resin and 10 parts of drips
It is green；Wherein, it is 1 that silvalin, which is mass ratio,:2 aramid fiber and the mixture of nylon fiber.
Above-mentioned submarine cable effectively increases the NdFeB permanent magnets of core by inhaling the design of hydrogen filler and copper strips；Pass through two
The use of layer waterproof layer, effectively increases the whole block-water performance of cable.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
Domain is included within the scope of the present invention.
