Abstract
The invention provides a polystyrene based flame-retardant wire-cable filling material belonging to the technical field of composite materials. The polystyrene based flame-retardant wire-cable filling material is obtained by adding a polystyrene waste, a flame retardant and a toughening agent into a high-speed mixing machine to perform kneading, then putting the mixture into a twin-screw extruder, adding a foaming agent for extrusion, and cooling in water. The wire-cable filling material is a frothed string of which the single-string diameter is less than 3mm, the stretching resistance of the wire-cable filling material is not less than 30N, the oxygen index of the wire-cable filling material is 36-55, and the wire-cable filling material has the characteristics of strong water resistance, light weight, flame retardance, low cost and the like, so that the problems of a common wire-cable filling material on the market at present are effectively solved, and the wire-cable filling material has a good market application prospect.
Description
Technical field
The present invention relates to a kind of electric wire packing material, relate in particular to a kind of preparation of polystyrene-based flame-retardant electric wire and cable packing material, belong to technical field of composite materials.
Background technology
Cable all needs to use packing material in preparation process, and the object that common cable is filled is: make cable core structure stable, keep the rounding property of cable; With packing material cheaply, substitute the more expensive sheath material of price; Cable center's bedding core of multicore structure also plays mechanical damping effect, strengthens shock resistance and the extrusion performance of cable.Packing material generally comprises PP punching fiber crops, cotton paper, cotton thread, tNonwovens, the PP band that foams, PE and PVC film, self-adhesion copper aluminium foil, two copper aluminium foils of leading, anti-elater, nylon wire etc.Because the rope made of hemp, cotton yarn are soft, during stranding, form-dependent character is good, fills more in fact, can keep stranding rounding, can save sheath rubber, reduce costs, because of but the most frequently used cable filler.But the rope made of hemp and cotton yarn have a fatal technique weakness, exactly after extruding sheath rubber, easy moisture absorption gas in the process of sulfuration, causes the foaming phenomenon of sheath rubber, has seriously affected sheath performance and the outward appearance of cable.Although cable socket has been done to end socket processing before sulfuration, but still can not guarantee non-foamingly, very easily cause cable quality accident.Another kind of conventional cable and wire packing material is polypropylene elastic cable, this material softness, and white, body is light, belongs to fibre product, after buying, without any secondary process, just can use, and the cable roundness of stranding is good, fills consolidation.But after extruding eraser sheath and vulcanizing, can cause cable outward appearance thickness uneven, like Bamboo-shaped; In high temperature vulcanized process, easily cause gasket for packing local melting, and with the adhesion of insulation layer phase, had a strong impact on insulating performance of cable.Other packing materials due to or containing fiber fines, or not fire-retardant, or high in cost of production reason, be restricted in actual applications.In addition, above-mentioned packing material is except above shortcoming, and maximum weakness is not fire-retardant, easily causes fire hazard.Therefore prepare a kind of mechanical property high, light weight, fire-retardant electric wire packing material is the new focus of industry development.
Summary of the invention
The object of the invention is for problems of the prior art, a kind of light weight is provided, the preparation method of the polystyrene-based flame-retardant electric wire and cable packing material that mechanical property is high, flame retardant properties is good.
The preparation of the polystyrene-based flame-retardant electric wire and cable packing material of the present invention, after waste polystyrene, fire retardant, toughner are joined in high-speed mixer and to be mediated, be placed in twin screw extruder, add whipping agent to extrude the cord of single diameter below 3mm, cooling in water, both polystyrene-based flame-retardant electric wire and cable packing material.
Above-mentioned fire retardant is that (preparation method of palygorskite grafting resol is shown in document to palygorskite grafting resol: the preparation of resol/attapulgite clay nano composite material and sign, wear antelope antelope etc., plastics industry, the 2nd phase in 2010, in the present invention, be crushed to 400 orders, with powder state, use) with the compound of melamine phosphate, wherein the mass ratio of palygorskite grafting resol and melamine phosphate is 1:1～1:5.The addition of fire retardant is 10～25% of waste polystyrene quality.
Above-mentioned toughner is commercially available universal plastic toughner, and as glycerol, Holland produces F102, CAS:212-421 etc.The addition of toughner is 1～5% of waste polystyrene quality.
Whipping agent is water vapour or carbon dioxide, and its addition is that 2～6%(water vapour of waste polystyrene quality or the interpolation quality of carbon dioxide can accurately be controlled by gas meter).
Electric wire packing material prepared by the present invention is the foaming cord of single diameter 3mm, and its stretching resistance is greater than 30N, and oxygen index is 36～55.During use, the afterturn of many foaming cords is used, and mechanical property is more superior.
Polystyrene-based flame-retardant electric wire and cable packing material of the present invention, has water tolerance strong, light weight, and the feature such as fire-retardant, cost is low, efficiently solves the problem that the common electric wire packing material of existing market exists, and has good market application foreground.
