The utility model is good in elastica, the fire-proof heat-insulating layer (2) does not break when the utility model is used under low temperature (-20 centigrade degrees), the fire-proof heat-insulating layer (2) is homogeneous and good in fire-proof heat-insulating effects, and the insulating layer of cables is not destroyed after being burnt by fire of 520 to 570 centigrade degrees.
Description
Technical field
The utility model relates to a kind of fire-proof and thermal-insulation band, is specially adapted to all kinds of cables.
Background technology
Along with the develop rapidly of China's electric power and communication career, transmission of electricity and telecommunication are with the cable various places, town and country that spread all over the country.Fireproofing of cable has become guarantees that transmission of electricity and telecommunication are unimpeded, and even one of anti-electricity-theft key.Usually the cable fire-proof method that adopts has two kinds at present: the one, on cable, directly extrude the flame retardant type cable cover(ing), and the major defect of this method is trouble of construction; The 2nd, adopt band to coat cable, this class band comprises: the 1. belt that makes with material with fire retardancy, as glass fiber tape, mica tape etc.This band can reach certain fire-retardant requirement, but effect of heat insulation is poor; 2. heat insulation base band and the compounded band of plastic film, though pliability and thermal insulation all have improvement, heat-resisting effect is still not enough; 3. the coating that has fire retardancy in the base band surface-coated forms the fire-retardant fireproof coating.This class coating can adopt organic siliconresin to make base-material usually, though the good heat resistance of this resin does not produce harmful chlorine during burning, selling at exorbitant prices causes cable cost to rise; Also can adopt chlorinated polyvinyl chloride, chlorinated rubber to make base-material, it is all harmful to human and environment to produce chlorine during the burning of this coating, and the band that makes with this base-material, at low temperature during as-20 ℃ of winding cables, coating may ftracture, and has influenced the flame retardant effect of band.In addition, above-mentioned these bands overwhelming majority is wrapped between the heart yearn and insulating barrier of cable, only at the destroyed back of insulating barrier competence exertion fire retardation.
Summary of the invention
The purpose of this utility model provides a kind of fire-proof and thermal-insulation band, and it has better elastic, use at low temperatures, and still not embrittlement of fire proof heat-insulation layer, fire proof heat-insulation layer is even, and fire-proof and thermal-insulation is effective.
Realize the technical scheme of the utility model purpose: a kind of fire-proof and thermal-insulation band, it has base band and fire proof heat-insulation layer, the fire proof heat-insulation layer that continuous dip-coating formation is all arranged in the both side surface of base band, base band is a glass fabric, and fire proof heat-insulation layer is that what to contain carbonifying catalyst, carbon forming agent, blowing agent, fire retardant and color stuffing is the coating of the fire-proof and thermal-insulation coating of base-material with the saturated polyester resin.
Technique effect of the present utility model: fire-proof and thermal-insulation band of the present utility model is that the glass fabric that fires with difficulty is a base band, and the fire proof heat-insulation layer that also has continuous dip-coating to form in the base band both side surface, therefore, has dual fire-proof and thermal-insulation effect, the fire-proof and thermal-insulation coating that particularly forms fire proof heat-insulation layer is to be base-material with the saturated polyester resin with good mechanical properties, so, the fire-proof and thermal-insulation band has favorable elasticity and still can embrittlement as-20 ℃ of fire proof heat-insulation layers at low temperature, the various fillers with fire protection flame retarding function that contain in this coating make fire-proof and thermal-insulation band of the present utility model have good fire-proof and thermal-insulation effect.Because fire-proof and thermal-insulation band of the present utility model has the fire proof heat-insulation layer that continuous dip-coating forms, therefore guarantee that product has even fire proof heat-insulation layer and stable fire-proof and thermal-insulation ability.The results showed, width is 40 ± 1mm, the fire-proof and thermal-insulation band of the present utility model of thickness 0.5 ± 0.05mm, and the overlapping mode by 50% is wrapped in the insulating barrier appearance of cable, carry out bonfire test then and promptly burnt 15 minutes at 520~570 ℃, the insulating barrier of cable does not destroy on inspection.Guarantee that like this when terrible disaster took place, cable can be protected, reduce the loss, and can prevent that electricity filching person from adopting the insulating barrier of burning power transmission cable, again by the hook stealing, and the generation of consequent casualty.
Description of drawings
Fig. 1 is the structural representation of fire-proof and thermal-insulation band of the present utility model;
Fig. 2 is the schematic representation of apparatus that continuous dip-coating forms fire proof heat-insulation layer, and wherein arrow is represented the base band track route;
Fig. 3 is the schematic cross-sectional view with the cable of the utility model heat insulating belt making.
Embodiment
Below in conjunction with accompanying drawing fire-proof and thermal-insulation band of the present utility model is further described in detail.
As shown in Figure 1, fire-proof and thermal-insulation band of the present utility model, it has base band 1 and fire proof heat-insulation layer 2, the fire proof heat-insulation layer 2 that continuous dip-coating formation is all arranged in the both side surface of base band 1, base band 1 is a glass fabric, and fire proof heat-insulation layer 2 is that what to contain carbonifying catalyst, carbon forming agent, blowing agent, fire retardant and color stuffing is the coating of the fire-proof and thermal-insulation coating of base-material with the saturated polyester resin.
Fire-proof and thermal-insulation band of the present utility model adopts device as shown in Figure 2 to form fire proof heat-insulation layer 2 in the continuous dip-coating of the both side surface of base band 1, base band 1 is immersed in the fire-proof and thermal-insulation coating of the formed fire proof heat-insulation layer 2 that is contained in the hopper 3 through running roller 5, then base band 1 promotes through running roller 5, enter drying tunnel 4 inner dryings, get off then and repeat said process again, continuous dip-coating three roads can obtain finished product fire-proof and thermal-insulation band altogether.
Fire-proof and thermal-insulation band 7 of the present utility model is wrapped in cable insulation 6 outer surfaces, and it is outer to be plastic sheath 8 (referring to Fig. 3).Because directly being wrapped in the insulating barrier outer surface of cable, fire-proof and thermal-insulation band of the present utility model can reach the fire-proof and thermal-insulation effect, therefore, need not change original production technology of cable, and the former cable that has or not fire-proof function, can have the fire-retardant fireproof function as long as outside its insulating barrier, twine fire-proof and thermal-insulation band of the present utility model.In addition, fire-proof and thermal-insulation band of the present utility model is used for other and requires the fireproof material surface also to have the fire-retardant fireproof function.Therefore of many uses.
