The present invention relates to a kind of flame-proof power cable, belong to cable field.
Background technology
Power cable is the cable for transmitting and distributing electric energy, and power cable is usually used in Urban Underground power network, power station
Lead line, industrial and mining enterprises' in-line power and mistake river sea submarine transmission line.In power circuit, cable proportion just gradually increases
Plus.Power cable is the cable product for being used to transmit and distribute high-power power in the basic routing line of power system, including 1-
500KV and any of the above voltage class, the power cable of various insulation.
Due to the working environment particularity of power cable, it is prevented fires, fire resistance requirement it is higher.
The content of the invention
To overcome above-mentioned deficiency, it is an object of the present invention to provide a kind of flame-proof power cable, by insulating barrier and inserts
Formula improve, increase cable fire-retardant, flameproof effect on the whole.
The solution of the present invention is as follows：Outside a kind of flame-proof power cable, including insulated wire cores and line insulated wire cores from the inside to the outside
The PP bands lapping layer of setting, fireprotection layer, metal screen layer, external sheath layer, described insulated wire cores are insulated by extruding line outside conductor
Layer is constituted, and described core sets inserts with wrapped interlayer, and described insulated wire cores are made up of following raw material：
Ethylene propylene diene rubber 60-80 parts, nitrile rubber 32-36 parts, GMA 4-6 parts, pi-allyl 2,4,
8-12 parts of 6- tribromo phenyl ethers, tetrasodium salt of EDTA 10-15 parts, 3.4-4.1 parts of trifluoromethayl sulfonic acid calcium, hexichol dichloro
Silane 10-13 parts, hexa 0.7-0.9 parts, polyethylene glycol stearate 2-5 parts, cobaltous octadecanate 2-6 parts, carbon black 4-6
Part, diatomite 25-29 parts, 0.6-0.8 parts of pest-resistant instrument agent.
Described pest-resistant instrument agent is dichloro ethofenprox, benzethazet acetofenate, the built agent of tetrachloroquinone, and mass ratio is 1：0.3：
0.41。
Further, described insulated wire cores are made up of following raw material：
76 parts of ethylene propylene diene rubber, 35 parts of nitrile rubber, 5 parts of GMA, pi-allyl 2,4,6- tribromo-benzenes
10 parts of base ether, 12 parts of tetrasodium salt of EDTA, 3.8 parts of trifluoromethayl sulfonic acid calcium, 12 parts of hexichol dichlorosilane, hexa-methylene
0.8 part of tetramine, 3 parts of polyethylene glycol stearate, 4.2 parts of cobaltous octadecanate, 5.5 parts of carbon black, 27 parts of diatomite, pest-resistant instrument agent 0.68
Part.
Further, described inserts is made up of following percentage by weight raw material：Waterglass 3.2-4.4%, carbon fiber 6-
9%th, mica stone flour 17.2-21%, water 15-18%, sodium antimonate 1.36-1.55%, strontium barium niobate 2.1-2.4%, nitrile (HTBN) 2.3-
2.6%th, pest-resistant ant agent 0.66-0.81%, remaining be aluminate cement；
Described pest-resistant instrument agent is dichloro ethofenprox, benzethazet acetofenate, the built agent of tetrachloroquinone, and mass ratio is 1：0.3：
0.41。
Inserts production method is comprised the following steps：
Water, aluminate cement, mica stone flour are mixed into 2-3min；Sodium antimonate, strontium barium niobate is subsequently added into mix
1min；It is subsequently added into carbon fiber, pest-resistant ant agent and mixes 3-5min；It is eventually adding waterglass and mixes 30sec, obtains final product
Rationally, fire-retardant, effect is obvious for cable insulation layer formula of the present invention.By the pest-resistant instrument agent added, insect can be reduced to electricity
Cable is damaged.
Inserts selection aluminate cement of the present invention is major ingredient, due to being free of tricalcium aluminate and calcium hydroxide in Behavior of Hardened Cement Paste,
And packing is larger, therefore acted on very strong anti-sulphates corrosive, meanwhile, also with stronger heat resistance, good flame retardation effect.
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 are high, and density is low, higher than performance, and without creep, superhigh temperature resistant under non-oxidizing atmosphere, fatigue durability is good, thermal expansion system
Number is small and with anisotropy, and good corrosion resistance, 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, increase pliability, on the other hand, also played strong
Change corrosion-resistant effect and shielding action, it is ensured that the normal work of core.
Mica powder is the resilient meagre chip of transparence, and high mechanical strength, electrical insulating property is good, high temperature resistant, acid and alkali-resistance, anti-
It is rotten.Physical property is superior, stable chemical nature.With aluminate cement, liquid fourth is fine mix after, with more preferable corrosion resistance
Energy.Sodium antimonate, strontium barium niobate is added to add increase inserts intensity, it is ensured that anti-dilatory effect.
