Background technique
With the gradually quickening of urbanization process, urban planning increasingly tends to modernize.In Process of Urban Development, electricity
Cable becomes minimum construction requirements with entering.Meanwhile during urban renewal, it is also desirable to skyborne various cables will be set up
Enter ground.It puts cable underground and is often constructed at present using trenchless technology, this construction method has and do not influence traffic, over the ground
The advantages that layer structure destruction is small, and the period is short, is suitable for simultaneously, and using non-excavating construction method, the requirement for cable is high, has
Show themselves in that cable needs high, rigid good toughness etc. with intensity, in addition, the characteristics of due to cable itself, it is also necessary to have
The characteristics of high flame retardant, causes fire to prevent short circuit etc., causes safety accident.
The sheath material of most of cable, except must have higher insulation resistance, dieletric strength or low dielectric loss
Outside, it is necessary to take into account good physical mechanical property, such as tension, counter-bending, anti-vibration, antitorque；And due to adapt to not
Same use environment and occasion has the requirement such as tear-proof, high-low temperature resistant, weatherability, oil resistant, solvent resistant；Some then be at
The composite request that product cable proposes, such as radially, longitudinally pressure sealing, fire-retardant, fire resisting.Before these requirements are overlapped mutually
It puts, needs to improve the comprehensive performance of cable cover(ing).
Summary of the invention
In order to solve the problems, such as to mention in above-mentioned background, it is an object of that present invention to provide a kind of wear-resisting stretch-proof cable cover(ing)s
Material and preparation method thereof, the sheath excellent physical properties produced, product is wear-resisting, stretches drawing, tearing toughness, screen resilience performance
By force；And have it is good heat-resisting, resistance to combustion, radiation hardness, resistance to ozone, acid and alkali-resistance, chemical reagent-resistant performance, production cost is low, use
Service life is long.
To achieve the above object, the invention provides the following technical scheme:
A kind of wear-resisting stretch-proof cable jacket material, is made of: chlorinated polybutadiene 70 ~ 105 following raw material according to parts by weight

10 parts, change 20 ~ 27 parts and 2 ~ 5 parts of surfactant of surname inorganic filler.
As a further solution of the present invention: the surfactant includes the raw material composition of following weight fraction: polyethers
5 ~ 10 parts of polyalcohol, 7 ~ 10 parts of triphenyl phosphate, 7 ~ 10 parts and 10 ~ 13 parts of phosphite ester of cyclohexanone.
As a further solution of the present invention: described to change surname inorganic filler by nano silica, ceramic fibre, carbon fiber
Dimension, asbestos fibre, diatomite and expanded vermiculite are prepared in 1:1:1:1:1:1 ratio.
As a further solution of the present invention: the dithiocarbamates is by antimony dithiocarbamate, two sulphur
According to parts by weight for carbamic acid molybdenum, nabam, aminodithioformic acid potassium and aminodithioformic acid bismuth
It is formulated than 1:2:1:1:1.
As a further solution of the present invention: a kind of preparation method of wear-resisting stretch-proof cable jacket material, by following system
Standby step forms:
(1) weighing according to the ratio of surname inorganic filler raw material each component will be changed, it is spare, in nano silica, ceramic fibre, carbon fiber
In dimension, asbestos fibre, diatomite and expanded vermiculite, it is added in the silane coupling agent that 3-5 times of weight mass fraction is 1-3%, ultrasound
Disperse 30-40min, is dried to obtain modified inorganic filler；
(2) chlorinated polybutadiene, phenolic resin, brominated Polystyrene are first moulded on 80-90 DEG C of open mill according to parts by weight
Practice, after moulding and practicing completely, surfactant and dithiocarbamates is added, repetition is kneaded 10-15min and rubber master batch is made；
(3) roller temperature is raised to 130-155 DEG C, change surname inorganic filler and the rubber master batch that step (1) is obtained are total on hot-rolling open mill
Mixed 10min, is gradually added white carbon black, magnesia, isophthalic acid ester, petroleum microwax, citrate after being blended uniformly,
Calcium stearate, it is thin it is 3-5 times logical after, be uniformly mixed spare mixture；
(4) by extruding pelletization, the temperature setting of the extruder in the mixture investment double screw extruder prepared in step (3)
It is 150-220 DEG C, pellet is after drying, screening, packaging.
As a further solution of the present invention: a kind of wear-resisting stretch-proof cable jacket material and preparation method thereof, feature exists
In being made of following raw material according to parts by weight: 90 parts of chlorinated polybutadiene, 66 parts of phenolic resin, brominated Polystyrene 18
