Description
Technical field
This utility model relates to a kind of cable, especially relates to a kind of fire resistant flexible environment-friendly cable.
Background technology
At present, domestic skyscraper, hospital, mine, metallurgy, boats and ships, power station, subway, tunnel, petrochemical industry and equipment
Fire-retardant and the Halogen that intensive place etc. are special, low cigarette, low toxicity.The occasion that fire safety condition is high, the cable insulation used,
Restrictive coating mostly has the insulant using Halogen.Fire once spreads, and not only can produce substantial amounts of dense smoke, and can produce tool
There is the hydrogen halide that the corrosivity of " secondary disaster " is the strongest, jeopardize the life of people, harm equipment and pollution environment, for low cigarette
It is strong that halogen-free material all has water absorption, and after insulation absorbs water, insulating properties are anxious and play declines, and meets high temperature sheath meeting cracking phenomena, with
The high speed development of World Economics and World Environment Organization to the requirement of ring protection and people's attention to safety, suddenly wait upon exploitation
Environmental type safety cable is to meet the needs of human kind sustainable development, and this is the development trend of novel cable.
Chinese patent ZL 201420596892.1 discloses a kind of fire-resistant, oil resistant, wear-resisting, high temperature resistant environment-protective power cable,
Including, a cable outer layer, is a high fire-retardance lapping layer, a halogen-free flameproof sheath, a high temperature resistant sheath protection the most successively
Layer；And, at least one cable inner core, be positioned at this cable outer layer, this cable inner core be the most successively a conductor wire core, one
Flame retardant coating, an insulating barrier, a high-temperature insulation protective layer；Wherein, in the gap formed between this cable outer layer and this cable inner core
It is filled with glass fiber rope.
Utility model content
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of fire resistant flexible is provided
Environment-friendly cable.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of fire resistant flexible environment-friendly cable, including cable inner core and the cable outer layer of parcel cable inner core, described cable
Inner core includes conductor wire core, and wraps up the thermal insulation layer of described conductor wire core, flame retardant coating and insulating protective layer the most successively,
Described cable outer layer includes wrapping up the most successively the ceramic lapping layer of described cable inner core, halogen-free flameproof restrictive coating and resistance to
Fire protective layer, is additionally provided with glass fiber rope packed layer between cable outer layer and cable inner core, and glass fiber rope packed layer is by glass fiber rope rack
Form with the water for cooling material of releasing being filled in glass fiber rope rack.
Cable inner core in cable outer layer is provided with at least one.
Described conductor wire core is drawn by highly purified oxygen-free copper bar and forms.
Described thermal insulation layer is Ceramic silicon rubber layer.
Described flame retardant coating is Muscovitum belt.
Described insulating protective layer is low smoke and zero halogen insulation material layer.
Described water for cooling material of releasing is aluminium-hydroxide powder.
Described refractory protection extrudes structure sheaf for fire prevention polyolefin.
Described halogen-free flameproof restrictive coating is made up of acid source, carbon source and source of the gas three part, and wherein, acid source is dehydrant, carbon
Source is carbon forming agent, and source of the gas is foaming agent.In the environment of fire, by acid source (dehydrant), carbon source (carbon forming agent) and source of the gas (foaming
Agent) three parts composition sheath materials expand rapidly, surface formed densification porous carbon froth bed, be securely attached to cable
On, play the most heat insulation, oxygen barrier, press down cigarette, and the effect of molten can be prevented.Flame-retardant effect is mainly by expanding
The end conduction of heat of a heat insulation foaming structure of layer of charcoal and to thermal-radiating reflection, every being acted on, limits and supplies underlying polymer
Oxygen and suppression can the releasing of property degraded gas and the melt and dissolved drippage of prevention polymer combustion generation effectively be so to reach resistance
Fire fire-resistant effect.
Compared with prior art, this utility model has the advantage that
(1) flame retardant effect is excellent, and flexible degree is high: this utility model is conventional insulating protective layer, flame retardant coating, fire-resistant guarantor
Outside the structures such as sheath, being also additionally arranged glass fiber rope packed layer, in glass fiber rope packed layer, glass fiber rope self just has good fire-retardant effect
Really, during and as rack, additionally it is possible to the collision etc. between effective buffering cable inner core and cable outer layer, cable is improved
Abrasion resistant effect, meanwhile, fills aluminium-hydroxide powder in glass fiber rope, and it endothermic decomposition will discharge knot when about 200 DEG C
Brilliant water, water of crystallization produces steam in heat absorption, can effectively play fire-retardant fireproof effect.
(2) outer surface at conductor wire core is also enclosed with Ceramic silicon rubber layer, and Ceramic silicon rubber is being made pottery by thermosetting
There is before porcelain housing good heat-proof quality, and when the outer all of insulating refractory of Ceramic silicon rubber layer lost efficacy, pottery
SiClx rubber also can generate ceramic shell under thermal-flame, protects conductor wire core from height as last layer of fire proof construction
The dinectly bruning of warm fire flame.
