Abstract
The invention discloses a fire-retardant binding belt for a cable and a manufacturing method therefor, and relates to a fire-retardant binding material and a manufacturing method therefor. The fire-retardant binding belt comprises a substrate and fire-retardant adhesive outside the substrate, and is characterized in that firstly, polyacrylate emulsion is matched with a fire-retardant agent, a dispersion agent, an addition agent and the like to form the fire-retardant adhesive via mixing, agitating and screening; secondly, the fire-retardant adhesive is combined with the substrate material in coating and dipping manners; and lastly, the combination of the substrate and the fire-retardant adhesive is baked, cut and packed to form the binding belt. The fire-retardant binding belt provided by the invention has an ideal fire-retardant effect, enables a cable core to be firmly bound, improves fire protection safety performance, is simple to manufacture and stable in technical function, and has lower manufacturing cost.
Description
Technical field
The present invention relates to a kind of cable-flame retardant Binding material and manufacture method thereof, particularly relate to fire-retardant binding strap and manufacture method thereof for a kind of cable.
Background technology
Cable is in service, due to the powerful function of current of cable core, the protruding thorn of impurity, pore and interior outer shielding layer in insulating barrier and damaged location all can be due to the infiltration generation water tree phenomenons of water, make the inner generation electric discharge of insulating barrier even puncture cable, and make metallic sheath produce the phenomenon of expanding with heat and contract with cold because cable core load variations can produce the temperature difference, therefore, must leave gap in metallic sheath inner side, but this gap just has water to infiltrate if do not filled, thereby there is breakdown accident.For addressing the above problem; and can laterally block water; applicant has declared the Chinese patent of " semi-conductive buffer sealing binding strap and manufacture method thereof " by name; this technology has played the effect of semi-conductive screen buffering electric field to a certain extent; also there is good water absorbing capacity simultaneously; laterally water-resisting ability, protection cable avoids making moist.But still Shortcomings part: there is no anti-flammability, Performance-based fire is low.
In middle high-pressure electric power cable, the insulating barrier of the insulated wire cores in oversheath has absorbed the heat being transmitted by sheath outward, and insulating barrier temperature is raise, and impels depolymerization (decomposition) to become low molecular weight volatile thing.Reach the ignition temperature of analyte when temperature continues to raise, then cause burning in the situation that has air to exist, then produce heat this hot spots temperature is further raise, until all burn up.For the purpose of reliable, generally becoming cable core to dress outside layer 2-3 inhibiting tape as flame-retardant layer.
In the construction of cable, use at present fire-retardant bringing to achieve the above object, but owing to there is no tack, band itself is harder, holds and be not very tight, bring unnecessary difficulty to subsequent technique, and production cost is high, should not popularize.
Summary of the invention
The object of the present invention is to provide fire-retardant binding strap and manufacture method thereof for a kind of cable, make it fire-retardant binding strap product flame retardant effect ideal, colligation cable core is more firm, improves Performance-based fire, and manufacturing process is simple simultaneously, technical performance stable, raising is wrapped up compactness and reduces production costs.
The present invention is achieved by the following technical solutions:
