Abstract
The present invention relates to a cable and a manufacturing method thereof, which makes an original cable using a reticular fiber rope of polypropylene as filling materials changed into a cable using plasticine as filling materials and technologically uses plasticine processing. Wire core cabling is respectively carried out, and then, filing and a sheath are once extruded. The present invention has the advantages of water immersion resistance and acidity and basicity resistance. Because the plasticine filling materials have little possibility of bonding with an insulation layer and the sheath, the cable is easy to peel off when used. Besides, the cable has the advantages of high flexibility, full and round external appearance and wide applicability.
Description
The invention belongs to the cables manufacturing field.
The packing material of present similar products at home and abroad; be to adopt the polypropylene mesh cordage; the effect of its filling mainly is the protection insulation; improve the presentation quality of product; reduce cost; but owing to fill poor air-tightness with this kind material, for there was dampness in the air and the environment of water retting and soda acid is poor for applicability, the roundness for cable improves also very limited simultaneously.Be after adopting the stranding filling wrapped, to extrude the sheath moulding again on the production technology of above-mentioned cable.The cable of this explained hereafter, insulating barrier and sheath are easily bonding, are difficult for during use peeling off, and pliability is low.
Purpose of the present invention is at the problem of above existence, provide a kind of and have humidity, water-fast dipping and resistance to acids and bases, cable that roundness is good, and the manufacturing technique method with this cable is provided, it is bonding that this cable insulation and sheath are difficult for, easily peel off the pliability height during use.
The present invention is achieved like this: with original cable filler, the polypropylene mesh fiber is used plasticine instead.
The material of plasticine is made up of following percentage by weight:
20 machine oil, 3～9% dioctyl phthalates 3～9%
Paraffin 1.5%～10% yellow wax oil 0.3～1.5%
Antioxidant D 0.15～1.5%
Stearic acid 0.15～10% calcium carbonate 50～80%
Be plasticine processing on the technology, the core stranding carries out respectively, fills then and an extrusion molding of sheath.
The processing technology step of plasticine is:
Cut glue → mastication → mixing → filtration → compressing tablet → slitting → deposit
↑
[liquid material (CaCO
3)] (small powder)
Plasticine plastic squeeze processing step:
A, plasticine is extruded with gelatin extrusion machine.
B helps head with electric furnace or other heating apparatus, and mould is heated, 50 ℃ of heads, 70 ℃～80 ℃ on mould
C, core rod die sleeve external diameter is identical, is 6mm to the mould distance.
D will be transferred to gelatin extrusion machine and plastic extruding machine series connection speed consistently during driving, maximum is no more than laying up diameter 2mm.
E, plasticine is extruded the back external diameter by gelatin extrusion machine should be with the laying up diameter basically identical, and maximum is no more than laying up diameter 2mm.
F behind the burnishing-in, all extracts glue in the fuselage only.
Advantage of the present invention: its cable is water-fast to be soaked and resistance to acids and bases, and plasticine packing material and insulating barrier and sheath are difficult for bonding, easily peels off during use, the pliability height, and the plentiful rounding of outward appearance, applicability is wide.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is a product structure schematic diagram of the present invention.
Embodiment 1, the present invention is by core 3 and wraps up in the insulating barrier 2 usefulness plasticine 4 that wrap in core 3 and do packing material and sheath 1 disposable extrusion modling, its technical process is as follows: plasticine 4 materials processings, and core 3 strandings carry out respectively, and plasticine 4 is done to fill and 1 extrusion moldings of sheath then.

1, cuts glue: carry out at bale splitter.
2, mastication: adopt XK-560 type or XK-400 type rubber mixing machine all can.Roller temperature is not higher than 6～8 minutes 60 ℃ of times, with natural and cis-butadiene cement separately mastication good after, again that its fusion is even, do not add other compounding ingredient.
3, mixing: open internal rubber mixer carry out all can, the opening rubber mixing machine temperature is not higher than 6～12 minutes 80 ℃ of times, it is 5～8 minutes that the internal rubber mixer glue furnacing temperature is not higher than 100 ℃ of times, with calcium carbonate CaCO
3(liquid material) adds during this period.
4, filter: filter in Φ 250 or 150 gelatin extrusion machines, temperature is controlled at below 90 ℃.
5, compressing tablet: in XK-560 or XK-400 type rubber mixing machine, carry out processing temperature and be controlled at 60～70 ℃, sizing material is pressed into continuous film.
6, slitting: on cutting cutter, film is cut into required width film.
7, deposit: require ventilation, drying to keep away periods of direct sunlight, room temperature preservation.
Plasticine 4 plastic squeeze technical processs:
1, plasticine 4 usefulness Φ 90mm gelatin extrusion machines are extruded.
2, help head with electric furnace or other heating apparatus, mould is heated, and head is heated 50 ℃, and mould is heated 70～80 ℃.
3, core rod die sleeve external diameter is identical, is 6mm to the mould distance.
Be transferred to consistent with Φ 150mm extrusion speed Φ 90mm gelatin extrusion machine when 4, driving.
5, after plasticine was extruded by Φ 90mm gelatin extrusion machine, external diameter should be with the laying up diameter basically identical, and maximum can not surpass laying up diameter 2mm.
6, behind the burnishing-in, glue in the fuselage is all extracted only.
