Abstract
The invention discloses a cable filler and a method for producing the same. The cable filler comprises a glass fiber cord and an oxygen isolation layer which is made from thermal plastic non-halogen fire-retardant polyolefin and is extruded on the outer circumference of the glass fiber cord. The external profile of the cross section of the oxygen isolation layer can be fan-shaped, triangular, round and the like. The method for producing the cable filler comprises the following steps: passing the glass fiber cord through a die hole of a shaping die of a plastic extruding machine, and towing theglass fiber cord by a tractor; filling particulate materials of the thermal plastic non-halogen fire-retardant polyolefin into a feed hopper of the plastic extruding machine; starting the plastic ext ruding machine and the tractor, extruding the particulate materials of the thermal plastic non-halogen fire-retardant polyolefin into a molten state by the plastic extruding machine, and then passing the molten material of the thermal plastic non-halogen fire-retardant polyolefin through the shaping die; and pulling out the glass fiber cord slowly by the tractor, cooling the glass fiber cord so that the non-halogen fire-retardant polyolefin is adhered to the periphery of the glass fiber cored to form the cable filler. When the filler is applied to manufacturing cables, glass fibers are not spilled over, the cables are soft, and the production environment is safe.
Description
Technical field
The present invention relates to a kind of packing material and production method thereof of cable.
Background technology
In the production process of cable; For guaranteeing the rounding property of cable, avoid phase mutual friction between the heart yearn simultaneously, need between heart yearn, add packing material; The normal rope made of hemp, the macromolecular material of adopting filled in the existing cable; These materials are inflammable, under conditions such as high pressure, thermal source, cause fire easily, and flame can carry the road to whole electric wire along the cable rapid spread.For addressing the above problem, available technology adopting non-flammable glass fiber material as packing material, also have the Halogen fire proofing of employing or bittern-free flame-proof material to fill, perhaps adopt fire-retardant mineral wool rope to fill.The Halogen fire proofing has good flame retardant property, still, and when fire takes place; This type Halogen fire proofing can produce a large amount of smog and poisonous corrosive hydrogen halides gas, causes secondary harm, and bittern-free flame-proof material amount of being fuming when burning is little; Do not produce poisonous, corrosive gas; Thereby be widely used, but the hardness of bittern-free flame-proof material self is bigger, and its cable of processing as cable filler has the shortcoming that hardness is big, poor performance is bent in folding; Glass fiber itself has good flexibility, and still, glass fiber material is prone to overflow; In air, form some tiny glass fiber dusts; Can cause direct labor's pruitus, shouting pain,, also suffer from occupational disease easily like the place of long-term work at this high glass fiber dust.Fire-retardant mineral wool rope has good flame retardancy, but it contains carcinogenic composition, and workman's suction can have a strong impact on health.
Summary of the invention
The present invention provides a kind of cable filler and production method thereof, and the problem that the glass fiber when making flexible cable to solve in the prior art overflows makes the environmental protection more of cables manufacturing place, safety.
Technical scheme of the present invention is: a kind of cable filler, the oxygen barrier layer that is made up of thermoplastics type's halogen-free anti-flaming polyolefin group that comprises that glass cord and glass cord periphery extrude.
That the profile shape of said oxygen barrier layer section can be is fan-shaped, triangle and circle.It uses as packed layer when cables manufacturing, mainly is the gap of filling between the heart yearn; Make cable rounding more, for this reason, oxygen barrier layer section profile is shaped as fan-shaped or leg-of-mutton packing material; Just can fill the gap between adjacent two heart yearns, make cable rounding more, appearance is more attractive in appearance; And its section is when rounded, and this cable filler is made convenient.This packing material is when carrying out cables manufacturing, because stopping of oxygen barrier layer arranged, glass fiber can not overflow, manufacturing site location environmental protection, safety; The cable of processing, it has good flexibility, and folding is curved, has good flame retardancy simultaneously.
The invention also discloses the manufacturing approach of above-mentioned cable filler, comprise the steps:
1) glass cord is passed in the nib of the shaper of plastic extruding machine, and draw with hauling machine;
2) thermoplastics type's halogen-free anti-flaming polyolefin granule materials of in the feed hopper of plastic extruding machine, packing into;
3) plastic extruding machine and hauling machine are worked simultaneously, and plastic extruding machine pushes thermoplastics type's halogen-free anti-flaming polyolefin granule materials, make its intensification be molten condition, pass shaper again; Hauling machine is slowly pulled out glass cord, and after the cooling, halogen-free anti-flaming polyolefin forms said cable filler attached to the glass cord periphery.
Aforementioned production method can guarantee that the glass cord external enwergy is coated with the halogen-free anti-flaming polyolefin material, can make glass cord not have tiny glass fiber and overflow, and has guaranteed Environmental security.
Plastic extruding machine produces high pressure and pushes the halogen-free anti-flaming polyolefin material when work, makes its intensification, makes material be molten state for guaranteeing that temperature can reach, and on the plastic extruding machine heating apparatus can be set.
Description of drawings

Fig. 2 is another structural representation of the present invention;
Fig. 3 is the third structural representation of the present invention.
Embodiment
As shown in Figure 1, be a kind of cable filler, the oxygen barrier layer 2 that constitutes by thermoplastics type's halogen-free anti-flaming polyolefin group that comprises that glass cord 1 and glass cord periphery extrude; Among Fig. 1, the profile of said oxygen barrier layer section is shaped as fan-shaped.The profile shape of this oxygen barrier layer section can also be triangle as shown in Figure 2, can also be circle as shown in Figure 3.
The production method of above-mentioned cable filler, its step is following:
1) glass cord is passed in the nib of the shaper of plastic extruding machine, and draw with hauling machine;
2) thermoplastics type's halogen-free anti-flaming polyolefin granule materials of in the feed hopper of plastic extruding machine, packing into;
3) plastic extruding machine and hauling machine are worked simultaneously, and plastic extruding machine pushes thermoplastics type's halogen-free anti-flaming polyolefin granule materials, and rely on heating apparatus, make its intensification be molten condition, pass shaper again; Hauling machine is slowly pulled out glass cord, and after the cooling, halogen-free anti-flaming polyolefin forms said cable filler attached to the glass cord periphery.
Owing to there is thermoplastics type's halogen-free anti-flaming polyolefin to be coated on the glass cord periphery, make glass fiber can not overflow, manufacture site surrounding health, the safety of cable, the dust of no glass fiber.With its cable of processing, has fire-retardant, soft superperformance.
