Abstract
The invention discloses a novel composite flame-retardant cable. The cable has a two-layer flame-retardant protection function because a ceramic silicon rubber composite tape is wound outside a conductor, and a mica tape is wound outside the ceramic silicon rubber composite tape; two high-flame-retardant materials are used for protection when the cable encounters fire and is burnt, and a closed ceramic pipe is formed when the outer flame-retardant silicon rubber tape encounters the fire and is burnt, so that flames and spraying water can be insulated, the inner mica tape is protected from damage, and the inner mica tape still can play a good flame-retardant protection effect even if the silicon rubber ceramic pipe is broken. According to the ceramic silicon rubber composite tape winding structure, the cable diameter can not be greatly increased, the cable is flexible when being used normally, and materials can be saved; specific extrusion equipment is not required to be arranged during processing; and the ceramic silicon rubber composite tape is wound inside an outer sheath, and the surface performance of the cable is not influenced at all. The cable still can normally work when the cable is burnt for over 120min at a temperature of 950+50 DEG C, and the water is immediately sprayed lasts for 3 minutes.
Description
Technical field
The present invention relates to power cable, especially a kind of NEW TYPE OF COMPOSITE fire-resisting cable.
Background technology
The fire-resistant wire and cable field of employment is the higher occasions of fire protection requirement such as various skyscraper facilities, commercial center, information network center (computer controlling center), large warehoused center, naval vessel, oil platform, subway, hospital, metallurgy, chemical industry, fireproof alarming system and aircraft control system, substitute the plain edition cable with fire-resistant wire and cable gradually both at home and abroad, especially external, fire-resistant wire and cable is in very great demand.Fire-resisting cable commonly used is two kinds, and a kind of is the mineral insulation fire-resisting cable, and this type of fire-resisting cable grade is higher, but the equipment investment height that cable is made, repay for a short time, manufacture difficulty is big, and drum length of cable is restricted, the hard crooked difficulty of cable, cable cost is very high, and producing and selling are restricted.Another kind of is the wrapped fire-resisting cable of mica tape (CN201965977U), this type of cable is most of to stand 750+50 ℃, burning 90min test, rare energy is by 950+50 ℃, burning 90min test, chance water cloud band namely comes off and causes cable short circuit, and work brings very big difficulty to fire rescue at once.CN202275623U discloses a kind of potteryization fire resistant fire-resisting cable, it is ceramic chemoprevention fire fire-resistant silicon rubber that its outer protective sleeve adopts material, it is ablated through 90 ~ 180min or above time in 650 ~ 1300 ℃ or above flame, silicon rubber is sintered into hard pottery housing in a short period of time, guarantee that circuit does not open circuit in ablation process, not short circuit, do not prolong combustion, extraordinary anti-flammability is arranged, thereby guarantee that circuit does not cut off the power supply in fire, provide safeguard for escaping and rescuing fire.But outer protective sleeve need adopt expressing technique, this just needs to be equipped with special-purpose extrusion equipment, and because the bad processing characteristics of ceramic chemoprevention fire fire-resistant silicon rubber, be bound to make extrude wall thickness can not be enough thin, so just increased processing cost and cost of material greatly.Also be the bad processing characteristics owing to ceramic chemoprevention fire fire-resistant silicon rubber in addition, the bad control of expressing technique, the surface quality of products obtained therefrom is bad.
Summary of the invention
The purpose of this invention is to provide a kind of NEW TYPE OF COMPOSITE fire-resisting cable.
This NEW TYPE OF COMPOSITE fire-resisting cable is wrapped potteryization silicon rubber composite band outside conductor.
In order to strengthen fire-resistant effect, also in order to save cost, the present invention's wrapped mica tape also outside pottery silicon rubber composite band inner wire.
In order to make winding effect better, mica tape preferably twines in the same way with potteryization silicon rubber composite band.
Lap when mica tape is wrapped is 30% ~ 40% of mica tape width.
Lap when potteryization silicon rubber composite band is wrapped is 15% ~ 20% of potteryization silicon rubber composite band width.
The thickness of the pottery silicon rubber composite band that the present invention uses is 0.08 ~ 0.3mm.Be preferably 0.1 ~ 0.2mm.
In the NEW TYPE OF COMPOSITE fire-resisting cable of the present invention, the outer wrapped potteryization silicon rubber composite band of conductor is met fire burns can form a sealing earthenware, can cut off flare and spray quinoline water, guarantee that such cable can be at 950+50 ℃, above and the 3min that sprays water of burning 120min still can operate as normal at once, cable still can keep the circuit integrality in burned flame when breaking out of fire in other words, guarantee that electric equipment normally moves, make fire-fighting equipment and the facility can operate as normal, thereby guaranteeing that disaster-stricken people can have time enough to flee the scene, to avoid or to reduce loss of life or personal injury and property loss.
The pottery silicon rubber composite band of wrapped thin softness, rather than be extruded as protecting pipe, cable size can not increased greatly, very soft when normally using, and save material.Adding does not need to be equipped with special-purpose extrusion equipment man-hour, can use same equipment with wrapped mica tape.In addition, within the wrapped externally sheath of pottery silicon rubber composite band of thin softness, do not influence the surface property of cable fully yet, avoided bad this defective of processing characteristics of ceramicization silicon rubber.
Potteryization silicon rubber composite band is used in combination with mica tape; has double-deck refractory protection; there are two kinds of high refractory materials to protect when meeting fire burns; outer fire-resistant silicon rubber band is met fire burns can form a sealing earthenware; can cut off flare and spray quinoline water; protection internal layer mica tape is injury-free, and that is afraid of the breakage of silicon rubber earthenware, and the mica tape of internal layer still can play fine refractory protection effect.And the use of mica tape can also reduce the consumption of potteryization silicon rubber composite band, further reduces cost.In general, be that wrapped one deck refractory material then needs lap is controlled to more than 50% of twining package tape width, as only use in the prior art fire-resisting cable that mica tape makes its lap just need be at more than 50% of mica tape width when wrapped.As method of the present invention pottery silicon rubber composite band is used in combination with mica tape, lap when mica tape is wrapped is 30% ~ 40% of mica tape width, and the lap of potteryization silicon rubber composite band when wrapped is 15% ~ 20% of potteryization silicon rubber composite band width.
Description of drawings
Fig. 1 is the structural representation of a kind of form of NEW TYPE OF COMPOSITE fire-resisting cable of the present invention.
Embodiment
See Fig. 1.Conductor 1 outer wrapped be mica tape 2, wrapped outside mica tape 2 is potteryization silicon rubber composite band 3.Potteryization silicon rubber composite band 3 is twined in the same way with mica tape 2.Insulating sleeve 4 outside wrapped good pottery silicon rubber composite band 3.
In the above-mentioned process, the lap when mica tape is wrapped is 35% of mica tape width, and the lap when potteryization silicon rubber composite band is wrapped is 15% of potteryization silicon rubber composite band width.The thickness of the pottery silicon rubber composite band of using is 0.14mm.
Having finished conductor cores that said process makes and filled core 5 one with two, to reinstate fire-retardant band 6 wrapped, extrudes oversheath 7 at last, a kind of form of NEW TYPE OF COMPOSITE fire-resisting cable of the present invention.The filled core 5 here, fire-retardant band 6 and oversheath 7 are conventional structure and material, and finish making and the course of processing in the mode of routine.
