Description
Technical field
The present invention relates to field of cable technology, specially a kind of preparation method of cable jacket.
Background technique
With the development of China's science and technology, earth-shaking variation is also had occurred in Ship Equipment, in military equipment all
There is very big application, China has vast sea area that there must be a large amount of naval vessel to resist foreign aggression, these naval vessels go to sea
After have to carry out just approach after surveying magnetic and demagnetization when returning base maintenance, survey magnetic and demagnetization have to dedicated survey magnetoelectricity cable
And degaussing cable, far apart from operation field due to surveying magnetic machine and Deperming Facility, there are also very big drops sometimes, in China
South Sea ultraviolet light is strong, corrosive properly is strong, this requires that one side naval vessel, which should have, certain defencive function to cable,
In this case and naval vessel is clearly to be difficult to accomplish, on the other hand we it has to be considered that cable itself should have uvioresistant
The function of line function, anti-seawater corrosion, this just needs the external sheath layer material of cable to need certain anti-ultraviolet function and prevent
Seawater corrosion function, there are no a kind of cable jackets with this excellent properties so far.
Closed experienced glue machine abbreviation mixer, also known as masticator, are mainly used for plasticating and being kneaded for rubber, mixer is one
Kind be equipped with a pair of of specific shape and the opposite rotor turned round, under adjustable temperature and the air-tight state of pressure intermittence to polymerization
The machinery that object material is plasticated and is kneaded mainly is filled by banburying chamber, rotor, rotor seals, charging material pressing device, discharging
It sets, the part such as transmission device and base forms.
It needs to mix various raw material using mixer during cable jacket is processed, currently,
During being plasticated and being kneaded to rubber, the addition of raw material successively carries out existing mixer, and multiple
It is to be connected at gating location with outside air frequently during addition raw material, it cannot be in the process to add materials
In remain that mixer in air-tight state, influences refining glue efficiency and refining glue effect.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation methods of cable jacket, to solve to propose in above-mentioned background technique
Existing cable oversheath cannot have both the function of anti-ultraviolet function and anti-seawater corrosion simultaneously, and carried out using mixer
Airtightness poor during refining glue.
To achieve the above object, the invention provides the following technical scheme: a kind of preparation method of cable jacket, including such as
The raw material of lower parts by weight:
