Accompanying drawing explanation
Accompanying drawing 1 illustrates a kind of core of steel cord the cross section with polymeric coating.
Accompanying drawing 2 illustrates a kind of cross section of steel cord.
Accompanying drawing 3 illustrates one embodiment of the invention.
The specific embodiment
According to the present invention, belt 20 is strengthened by steel cord 16, and the steel cord here has the core 12 being made up of single or multiple core thighs, has and is greater than the skin that an outer layer strand forms, and has one layer of polymeric coating 14 on core.
Steel cord can make by the following method.
Raw MAT'L is high-carbon steel wire rod, and composition is: carbon content is at least 0.45%, manganese content from 0.30% to 0.70%, and silicon content from 0.15% to 1.0%, maximum sulphur content 0.03%, maximum phosphorus content 0.03%, all percentums are percent by weight.Other element as chromium, vanadium also likely, content is for being up to 0.40%.
This kind of wire rod, through wire rod dephosphorization, removed the oxide on wire rod surface with machinery or chemical pickling, and then water rinses and is dried.Follow dried wire rod and can carry out a series of dry diameter that draws to reduce, for example, the wire rod from 5.5mm to 8mm, moves a suitable mid diameter to.
If necessary, perhaps centre experiences hot-cured process to meet the needs of further distortion.
To first mid diameter d1, for example 3.0mm is to 3.5mm, and the monofilament after dry drawing enters first heat treatment, cries quenching.Quench for first austenitizing, reduce to 600 to 650 degrees Celsius from about 1000 degrees Celsius, complete from austenite to pearlitic transformation.Monofilament like this can carry out next step mechanically deform.
Then filament diameter is further drawn by dry, and diameter is from d1 to the second mid diameter d2 of first mid diameter.Second mid diameter d2 is generally 1.0mm to 2.5mm.
When filament diameter is to when second mid diameter d2, monofilament enters second and quenches, i.e. austenitizing is again reduced to 600 to 650 degrees Celsius from 1000 degrees Celsius, completes from austenite to pearlitic transformation.
If the dry overall diameter that draws rear minimizing of the twice told is not above very large, also can move d2 to from wire rod together this time.
At this moment steel wire need to add anticorrosion coating, for example spelter coating, Zinc alloy coated.Coating can obtain by hot dipping or electroplating technology.
Then carry out a series ofly wetly drawing operation to thering is the monofilament of anticorrosion coating, until reach required final monofilament.
The steel cord of structure 7 × 7+7 × 19W is as a preference, method for making with this casehistory steel cord 16: after the monofilament being obtained by above technique, first manufacture the core 12 of steel cord, then on core, coat one layer of polymeric coating 14, and then around upper outer layer strand 15.
By expressing technique, above-mentioned core 12 is carried out to coating, after a kind of poly-mer of solid granulates shape melts equably, under the stirring of screw rod and extruding under, poly-mer flows out mould with uniform, stable speed.The core of steel cord, simultaneously also by this mould, is just capped last layer polymeric coating 14 like this on it, polymeric coating material may be thermoplastic polyurethane (TPU), polyamide 11(PA11), polyamide 12(PA12), polyamide 16(PA16), polyethylene (PET).Polymeric coating 14, under expressing technique, likely can infiltrate core thigh inside.
Accompanying drawing 1 illustrates the cross section of the core of steel cord, the thickness T 1=(D-d)/2 of polymeric coating, the circumscribed circle diameter that d is core, the external circle diameter of D polymeric coating.The thickness of polymeric coating 14 may be from 0.05mm to 0.15mm, better, and from 0.08mm to 0.12mm.
It is 7 × 7+7 × 19W steel cord, 16 cross sections that accompanying drawing 2 illustrates structure.
This steel cord 16 comprises core 12, polymeric coating 14 and outer layer strand 15.Core 12 is structures of 7 × 7, comprises a central strand and the six roots of sensation the first outer layer strand, and a central strand is the strand of a 1+6 structure, and wherein the diameter of Yi Gen center monofilament is 0.43mm, and the diameter of the outer monofilament of the six roots of sensation is 0.39mm, and the lay pitch is 17.5mm, twists with the fingers to being Z.The six roots of sensation the first outer layer strand is the strand of 7 × 1 structures, and filament diameter is 0.32mm, and the first outer layer strand lay pitch is 17.5mm, twist with the fingers to for S sth. made by twisting to.The six roots of sensation the first outer layer strand is twisted with the fingers and is become core thigh to Z and central strand twisting with lay pitch 26mm again.The skin of steel cord is made up of seven outer layer strand 15, structure is 7 × 19W, by 7 strands and per share Wa Lindun W (Warrington) structure that has 19 monofilament to form, 19 monofilament with identical sth. made by twisting to forming with lay pitch twisting, one, center steel wire, 6 of nexines are the steel wires of homogeneous size, outer 12 is that 6 major diameter steel wires and 6 minor diameter steel wires are spaced apart, 6 major diameter steel wires just on the depression of nexine steel wire, 6 minor diameter steel wires just nexine steel wire just above.Outer field seven strands that outer layer strand 15 is W structures, outer layer strand 15 comprises 19 monofilament, structure is 0.43+6 × 0.40+6 × 0.33/0.40, represent outer layer strand 15 be by 19 monofilament with identical sth. made by twisting to forming with lay pitch twisting, wherein, center filament diameter is 0.43mm, and the six roots of sensation filament diameter of the second layer is 0.40mm, and 12 monofilament of the 3rd layer comprise the monofilament that the six roots of sensation diameter that the arranges space monofilament that is 0.33mm and six roots of sensation diameter are 0.40mm.The lay pitch of outer layer strand 15 is 14mm, twist with the fingers to S twist with the fingers to.The lay pitch of steel cord 16 is 70mm, twist with the fingers to for Z sth. made by twisting to.In twisting process, the sth. made by twisting of each twisting is to vice versa.
Accompanying drawing 3 illustrates one embodiment of the present of invention.
Obtaining structure by above-mentioned technique is after 7 × 7+7 × 19W steel cord 16, then obtains final belt 20 by expressing technique again.The base material 18 of belt may be made up of plastics, also may be made up of rubber.
