Abstract
The invention discloses a semiconductive flame retardant belt for cables and a manufacture method thereof. The semiconductive flame retardant belt for the cables comprises a framework and semiconductive flame retardant glue and is characterized in that the framework is fabric which has properties of strength, softness and non-hygroscopicity and is selected from one of glass fiber cloth, nylon fiber cloth and polyester fiber cloth. The manufacture method of the semiconductive flame retardant belt for cables is characterized by comprising the following process steps of: (1) manufacture of a framework material: manufacturing into the framework material according to specification requirements of a product; and (2) treatment of the semiconductive flame retardant glue outside the framework, wherein the semiconductive flame retardant glue is prepared by steps of mixing and stirring by taking a polyacrylic polymer as a main material, and the finished product is obtained by combining the semiconductive flame retardant glue with the framework through various modes of coating, impregnating, and the like, and then baking, parting off and packaging. The product of the invention has the advantages of favorable electric property, ideal flame retardant effect, simple production process, stable technical property and strong practicability.
Description
Technical field
The present invention relates to a kind of semiconductive fire proofing and manufacturing approach thereof, particularly relate to a kind of cable with semiconductive inhibiting tape and manufacturing approach thereof.
Background technology
In middle and high low power cable production process; Reason owing to manufacturing process; Inevitably the outer surface at conductor exists tip or projection, and the electric field of these tips or projection is very high, and high electric field must cause tip or projection in insulation, to inject space charge.The space charge that injects will cause the electric branchization or the water treeization of insulation.Concentrate in order to relax the inner electric field of cable; Improve the inside and outside surface field stress distribution of insulating barrier; Improve the electrical strength of cable, require between lead cable core and insulating barrier, insulating barrier and metal level, to be added with one deck semiconductive shielding layer respectively, be called conductor shield and insulation screen.
The insulating barrier of the insulated wire cores in the oversheath has absorbed the heat that is transmitted by sheath outward, and the insulating barrier temperature is raise, and impels depolymerization (decomposition) to become the low molecular weight volatile thing.Reach the ignition temperature of analyte when temperature continues to raise, cause burning under the situation that has air to exist again, produce heat then this hot spots temperature is further raise, all burn up up to cable.For the purpose of reliable, generally becoming the cable core outsourcing to prick the layer 2-3 inhibiting tape as flame-retardant layer.
In the construction of cable, use semi-conductive tape, fire-retardant bringing to achieve the above object at present, though have shielding and fire resistance, normally two kinds of structures that material repeatedly holds; The performance of two kinds of materials interacts; Reduced shielding and anti-flaming function, and production cost is high, should not popularize.
Summary of the invention
The object of the present invention is to provide a kind of cable with semiconductive inhibiting tape and manufacturing approach thereof; Be selected from have intensity, softness and non-hygroscopic fabric; Like glass fabric, nylon fiber cloth, polyester fiber cloth is skeleton; Apply above that or soak the semiconductive fire retardant glue and process cable and use the semiconductive inhibiting tape, with electric, the security against fire performance of raising cable and reduce production costs.
The present invention realizes through following technical scheme:
Cable is used the semiconductive inhibiting tape, comprises the semiconductive fire retardant glue that skeleton and skeleton are outer; Its skeleton is for having intensity, softness and non-hygroscopic fabric, is selected from wherein a kind of of glass fabric, nylon fiber cloth, polyester fiber cloth;
The semiconductive fire retardant glue, it comprises following composition:
A.50-200 the binders for coatings of mass fraction, binders for coatings is selected from acrylate copolymer, polyurethane, ethene vinyl chloride, polyester, polyamide, styrene-butadiene polymer or its combination;
B.10-50 the fire retardant of mass fraction, fire retardant is selected from antimony oxide, APP, phosphoric acid, magnesium hydroxide, aluminium hydroxide, Firebrake ZB, pentaerythrite, melamine, melamine, triaryl phosphate, trichloroethyl phosphate, chlorinated paraffin wax or its combination;
C.0.1-10 the dispersant of mass fraction, dispersant is selected from glyceryl monostearate, calcium stearate, barium sulfate, alkyl polyethylene oxides ether, Tissuemat E or its combination;
D.1-30 the conductive black of mass fraction;
C. deionized water.
Cable comprises following process steps with the manufacturing approach of semiconductive inhibiting tape:
(1) making of framework material: framework material is processed in the specification requirement by product;
(2) the outer semiconductive fire retardant glue of skeleton is:
I: form: the binders for coatings of 50-200 mass fraction, the fire retardant of 10-50 mass fraction, the dispersant of 0.1-10 mass fraction, the conductive black of 1-30 mass fraction, deionized water;
II: mix above-mentioned material, stirring makes the semiconductive fire retardant glue;
(3) above-mentioned glue is imposed on the framework material single or double to be processed linear speed 5-50 rice/min;
(4) oven dry: the prepared product of above-mentioned steps (3) is dried down at 100-200 ℃;
(5) cut:, cut into the product of specification the prepared product of above-mentioned steps (4);
(6) packing: the specification according to product is classified to finished product packing.
Advantage of the present invention and effect are:
Product excellent electrical properties of the present invention, flame retardant effect is desirable.And production technology is simple, and technical performance is stable, and is practical.
