Abstract
The invention discloses a ceramic silicon rubber fireproof control cable. The ceramic silicon rubber fireproof control cable comprises a cable core. The cable core of the cable is formed by twisting a plurality of insulated wire cores. Antiflaming low smoke zero halogen filler is arranged in the gap of the cable core, a sheath layer is arranged on the outermost layer of the cable core in an extruding mode, and ceramic fireproof composite belt cladding is arranged between the cable core and the sheath layer. The insulated wire cores are composed of conductors, conductor insulating layers and ceramic fireproof protective layers, wherein the conductor insulating layers and the ceramic fireproof protective layers are sequentially arranged outside the corresponding conductors in an extruding mode. The ceramic silicon rubber fireproof control cable has the remarkable fireproof function and the remarkable high-temperature blocking function, so that the internal structure of the cable is effectively protected against he mechanical change and the electrical performance change; the ceramic silicon rubber fireproof control cable has the advantages of being free of toxicity, tasteless, good in mechanical property, high in rigidity, hardness and toughness, good in air tightness, capable of resisting puncture, friction, high temperature, low temperature, chemicals and oil and the like.
Description
?
Technical field
The present invention relates to power cable field, specifically a kind of ceramic silicon rubber fireproof control cable.
Background technology
Now all can lay different cables in many occasions, to meet the needs of communication, energising etc.But in the time that fire occurs, fire will prolong along cable place combustion and spread to other places.Add up according to fire department, in Urban Fires, wherein more than 2/3 because causing that cable fire spreads, electrical equipment fault or cable traffic overload cause, in while many fire in the past, what cause personal life danger and " secondary harm " is mainly often acid gas and the toxic gas discharging after cable fire.Fireproofing of cable technology more and more causes people's concern, and becomes an important development direction of line cable industry.
Traditional fireproof cable is mounted in copper pipe, fills high temperature resistant solid material between copper pipe and cable, needs solid material pad device, vertical bag equipment and welding equipment etc. in production and manufacture process.Material and facility cost of investment is very high, thereby it is many that manufacturing cost has been increased.In addition, because high temperature resistant protective sleeve is copper pipe structure, filling be solid material, so Cable Bending Radius is little, particularly elevator requires softness with power cable and control cable, brings many inconvenience of installing to user.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of nontoxic, tasteless, mechanical performance is good, rigidity, hardness and toughness are high, puncture-resistant, rub resistance, high temperature resistant and low temperature, chemical proofing, oil resistance, the good ceramic silicon rubber fireproof control cable of air-tightness.
A kind of ceramic silicon rubber fireproof control cable of the present invention, comprises cable core, and its cable core is by many stranded the forming of insulated wire cores; The gap of cable core is provided with flame-retardant low-smoke halogen-free filler, and cable core outermost layer extrudes restrictive coating; Between cable core and restrictive coating, be provided with ceramic fire prevention composite band belting layer; Insulating layer of conductor, ceramic fireproof jointing sheath that described insulated wire cores is extruded in outside conductor by conductor, successively form.
Further improve, described ceramic fire prevention composite band belting layer adopts wrapped the forming of mylar band.
Further improve the PE restrictive coating that described restrictive coating adopts PE material to make.
Further improve, described insulating layer of conductor adopts fluoroplastics to make.
Beneficial effect of the present invention is:
1, described fire-retardant filler is flame-retardant low-smoke halogen-free filler, can realize fire-retardant object, because flame-retardant low-smoke halogen-free filler is not halogen-containing, do not produce toxicity, and does not contain heavy metal, therefore harmless to people's health, environmental protection.
2, described insulating layer of conductor adopts the insulating layer of conductor that fluoroplastics are made; That fluoroplastics have is high temperature resistant, do not prolong the characteristics such as combustion, and the insulating layer of conductor that adopts fluoroplastics to make can effectively reduce cable and in the time that fire occurs, occur prolonging the probabilities such as combustion.
3, the present invention utilizes fireproof jointing sheath effectively to protect the internal structure of cable that machinery variation and electrical property variation do not occur.
4, fireproof jointing sheath of the present invention, as the protective layer of core, under the effect of fireproof jointing sheath, can well be protected inner conductor.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, described a kind of ceramic silicon rubber fireproof control cable of the present invention, comprises cable core, and its cable core is by many stranded the forming of insulated wire cores; The gap of cable core is provided with flame-retardant low-smoke halogen-free filler 4, and cable core outermost layer extrudes restrictive coating 6; Between cable core and restrictive coating 6, be provided with ceramic fire prevention composite band belting layer 5; Insulating layer of conductor 2, ceramic fireproof jointing sheath 3 that described insulated wire cores is extruded in outside conductor 1 by conductor 1, successively form.
Described ceramic fire prevention composite band belting layer 5 adopts that mylar band is wrapped to be formed; Polyester film is taking PETG as raw material, adopts extrusion molding to make sheet, then the thin-film material of making through biaxial tension.Its mechanical performance is good, and rigidity, hardness and toughness are high, puncture-resistant, and rub resistance, high temperature resistant and low temperature, chemical proofing, oil resistance, air-tightness are good, can further guarantee that inside of the present invention does not occur that machinery changes and electrical property variation.
The PE restrictive coating that described restrictive coating 6 adopts PE material to make.
Described insulating layer of conductor 2 adopts fluoroplastics to make; That fluoroplastics have is high temperature resistant, do not prolong the characteristics such as combustion, and the insulating layer of conductor that adopts fluoroplastics to make can effectively reduce cable and in the time that fire occurs, occur prolonging the probabilities such as combustion.
It has possessed the good fundamental characteristics of silicon rubber elastic to the fireproof jointing sheath 4 that ceramic silastic material is made at normal temperatures; there is nontoxic, tasteless, high-low temperature resistant, resistance to ozone aging, weather-proof aging, good electrical insulation capability; also possessed the good processing characteristics of common high temperature silicon rubber, can keep flexible cable state at 40 degrees below zero to 300 degree left and right above freezing.Attack at flame; temperature reaches 800 degree when above; can be converted to rigid sponge ceramic body by original soft condition; the inner hole that produces of fireproof jointing sheath after hardening; be conducive to insulation; sponge ceramic body has the effect of significant fire prevention and obstruct high temperature like this, thereby effectively protects the internal structure of cable that machinery variation and electrical property variation do not occur.
The invention provides a kind of elevator fireproof flexible control cables version and implementation method; the above is only preferred implementation method of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also make some improvement, these improve and also should be considered as protection scope of the present invention.
