Description
Technical field
The present invention relates to a kind of cable, and in particular to environment-friendly type thermostable fireproof cable.
Background technology
Fire resistant cable, it is adaptable to ac rated voltage 300/500V and following, the signal detection in hot environment.
The fire-fighting that is particularly suitable for use in is used with the control of security system protective loop and the transmission line of power.Existing common cable is in high temperature
When being worked in environment, aging and incipient scorch phenomenon are also easy to produce, cable is lost performance, is damaged and can not use.It is reported that in recent years
In all kinds of electrically caused fire of China, have 60% above is by caused by electric wiring (electric wire).The line of electric wire
Core is made up of inorganic material, and its insulating barrier and restrictive coating are then made up of organic material.Because electric wire is responsible for
The effect of energy is transmitted, so it is in work with certain temperature.If this temperature exceedes insulating barrier and restrictive coating institute energy
The scope born, can result in these organic materials prolongs combustion or burning, cable is powered or information transmitting terminal.
The content of the invention
The technical problems to be solved by the invention are that existing cable that high temperature fire protecting performance is poor, are easily sent out in hot environment
Raw aging or incipient scorch phenomenon, are that cable is powered or information transmitting terminal, it is therefore intended that provide environment-friendly type thermostable fireproof cable, have
The energy normal table work under high temperature rated beneficial to cable, signal or electric energy transmission performance are normally used, moreover it is possible to ensure that cable has
There is longer service life.
The present invention is achieved through the following technical solutions：
Insulating barrier and screen layer, the screen are sequentially provided with outside environment-friendly type thermostable fireproof cable, including conductor, the conductor
Cover a layer outer cable and be radially sequentially provided with flame-retardant layer, water blocking layer, insulating layer and heat-resistant layer from inside to outside；The flame-retardant layer uses silicon
Alkane crosslinking polyolefin elastic body halogen-free flameproof layer, the water blocking layer is using the expansion powder coating polyester layer of polyacrylate, institute
Insulating layer is stated using aerosil thermal insulation layer, the heat-resistant layer is using the coating inorganic silicon materials of silicon powder alkali-free glass wool
Layer.
It is resistance to good insulation by setting the coating inorganic silicon material layer of silicon powder alkali-free glass wool in cable outermost layer
High-temperature behavior can effectively protect cable jacket layer not by high temperature failure, while having good wear-resisting, corrosion-resistant, moisture resistance
Energy；By setting one layer of temperature insulating material in heat-resistant layer, the thermal conductivity of aerosil thermal insulation layer is relatively low, is conducive to preventing
It is rapidly heated in high temperature environments inside cable and causes to damage, and layer sets halogen-free environment-friendly flame-proof layer in the cable, and using master
Dynamic water swelling waterproof layer is protected, and prevents flame-retardant layer from being influenceed during long-term use by the moisture absorption and losing fire resistance,
Can not occur etc. in particular cases to play protective effect in fire.
Preferably, the thickness of the insulating layer is 3~5mm.
The aerosil thermal insulation layer thermal conductivity that the present invention is used is low, can be sent out only with the ring set of 3~5mm thickness
Good heat-blocking action is waved, is conducive to mitigating cable weight.
Preferably, the flame-retardant layer is provided with the projection uniformly arranged, the projection towards integration in the outer rim of water blocking layer side
In embedded water blocking layer, and the raised thickness for being less than water blocking layer in the length along cable radial direction.
Because flame-retardant layer uses organosilane crosslinked polyolefin elastic-body halogen-free flameproof layer during long-term use, if cable soaks
Enter moisture, and the flame-retardant layer easily moisture absorption, then can decline the flame-resistant insulation effect of flame-retardant layer.By the way that flame-retardant layer and water blocking layer is embedding
Enter formula connection, significantly increase the contact area of flame-retardant layer and water blocking layer, be conducive to strengthening protection against the tide guarantor of the water blocking layer to flame-retardant layer
Shield is acted on, and water blocking layer can expand after absorbing water so that flame-retardant layer and water blocking layer contact even closer fixation.
Preferably, the insulating barrier is using adhesive-contented mica tapes temperature-resistant material layer.
By the way that insulating barrier is used to protect conductor using adhesive-contented mica tapes temperature-resistant materials layer, even if cable outer layer by
In the case of certain damage, the holding in a short time of conductor can be so maintained normally to be powered or information transfer capability.
Preferably, enhancement layer is additionally provided between the gentle heat-resistant layer of the insulating layer, the enhancement layer uses carbon steel belt layer.
It is mainly used in strengthening the mechanical strength and buckle resistance energy of cable with protective layer by using carbon steel, strengthens to leading
The protective effect of body.
The present invention compared with prior art, has the following advantages and advantages：
1st, environment-friendly type thermostable fireproof cable of the present invention, by setting silicon rubber temperature-resistant material in cable outermost layer, can have
Effect protects cable jacket layer not by high temperature failure, and has good moistureproof, corrosion-resistant protective effect；By being set in heat-resistant layer
One layer of temperature insulating material, the thermal conductivity of aerosil thermal insulation layer is relatively low, is conducive to preventing inside cable in high temperature environments
It is rapidly heated and causes to damage, and layer sets halogen-free environment-friendly flame-proof layer in the cable, and carried out using active water swelling waterproof layer
Protection, prevents flame-retardant layer from being influenceed during long-term use by the moisture absorption and losing fire resistance, it is impossible to special in fire generation etc.
In the case of play protective effect；
2nd, environment-friendly type thermostable fireproof cable of the present invention, because flame-retardant layer is hindered using organosilane crosslinked polyolefin elastic-body Halogen
Layer is fired during long-term use, if cable immersion moisture, and the flame-retardant layer easily moisture absorption, then can imitate the flame-resistant insulation of flame-retardant layer
Fruit declines.By by flame-retardant layer and the embedded connection of water blocking layer, significantly increasing the contact area of flame-retardant layer and water blocking layer, favorably
The moisture protection of flame-retardant layer is acted in enhancing water blocking layer, and water blocking layer can expand after absorbing water so that flame-retardant layer and water blocking layer
Contact even closer fixation.
