Description

A kind of deep sea cable protective cover material
Technical field
The invention belongs to field of cables, more particularly to a kind of cable jacket material suitable for deep-sea.
Background technology
Seabed is that a kind of cable of cable performance requirement highest is both required to meet laying in cable with power cable During high intensity pull and wear-resisting needs, it is also necessary to the environment of seabed high pressure and high corrosion can be resisted by having, simultaneously Also need to prevent baiting for marine organisms, long period of soaking there can not be harmful substance to come out polluted seawater, influence sea in seabed Water environment.
At present, substantial amounts of energy extraction needs electric power and power communication, and the transmission of marine clean energy resource all also will be a large amount of Using submarine cable.External sheath layer is located at the outermost layer of submarine cable, plays the basic protective effect such as waterproof, abrasionproof, anticorrosion. But in recent years, with the increase of ocean development dynamics so that the restrictive coating of submarine cable is often subject to the effect of external mechanical power And breakage occurs, the protection to inside is lost, seawater is in contact through waterproof layer with armouring wire or power supply conductor, is produced Raw damage.
Therefore, in order to meet some special laying environment, meet that marine site has sour environment, deep water laying, easily cast anchor There is reef in area, seabed, the needs that anti-marine borer corrodes, anti-marine animal baits etc., exploitation one kind is free of heavy metal, meets ring Guaranteed request, cable insulation can be operated in wet environment, have excellent anti-marine borer, can use a variety of in deepwater regions etc. External sheath layer seems especially important in the extrusion type being impregnated with without seawater of complicated rugged environment requirement.
The content of the invention
The present invention solves the technical problem of a kind of high-strength wearable submarine cable oversheath material is provided, can effectively change It is apt to the damage-retardation performance of existing submarine cable external sheath layer, safety and environmental protection, anti-marine animal baits.
In order to solve the above technical problems, the technical solution adopted in the present invention is：
A kind of deep sea cable oversheath material, it is characterised in that：Including the raw material in terms of parts by weight as follows：
65~72 parts of high density polyethylene (HDPE)

0.6~0.9 part of antioxidant
2~4.5 parts of makrolon
2.2~3.2 parts of cold resistant plasticizer
0.8~2.6 part of accelerator
6~8.5 parts of mica powder
0.6~1.2 part of magnesium hydroxide
0.3~0.6 part of benzoyl peroxide
0.8~1.4 part of tert-butyl peroxy base diisopropylbenzene (DIPB).
Preferably, cold resistant plasticizer is (2- ethyl hexyls) ester of phthalic acid two or citrate.
Preferably, accelerator is accelerator M or vulcanization accelerator TMTD.
Preferably, protective agent is made up of paraffin, oil microwax, EVA polymer and cationic surfactant, they Weight ratio is：1:1.5:3:0.3.
Preferably, the mixture of antioxidant 2,6- three-levels butyl -4- methylphenols and double octadecanol esters, three it Between weight ratio be 3:2.
The invention has the advantages that：
Brominated Polystyrene of the present invention has high flame retardant, heat endurance and photostability, can effectively improve the resistance of protective cover material Combustion, heat resisting and ultraviolet-resistant capacity；Basalt fibre, crocidolite and carbon fiber can effectively improve the strong of protective cover material Degree, and the ability of corrosion-resistant, the wear-resisting radiation proof of protective cover material can be improved.
The various raw materials of the present invention correspond to the mixing of ratio, are effective to ensure that the mechanical strength, corrosion-resistant, resistance to low of protective cover material Warm, wear-resisting and weather resistance, usage time length；Raw material environmental pollution of the present invention is small, can prevent that oversheath is extra large Foreign animal baits, high mechanical strength.
Carbon fiber quality is lighter than metallic aluminium, but intensity is higher than steel, and with corrosion-resistant, high-modulus characteristic axial direction Intensity and modulus is high, and density is low, higher than performance, no creep, and superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, thermal expansion system Number is small and has anisotropy, good corrosion resistance, and X-ray transparent is good.Good electrical and thermal conductivity performance, electromagnetic wave shielding are good. While on the one hand its addition ensure that intensity of packing, quality is reduced, increases pliability, on the other hand, is also played strong Change corrosion-resistant effect and shielding action, ensure the normal work of core.
Mica powder is the flexible meagre chip of transparence, and high mechanical strength, electrical insulating property is good, high temperature resistant, acid and alkali-resistance, is prevented It is rotten.Physical property is superior, and chemical property is stable so that cable outer sheath material has more preferable decay resistance.
