Description
Technical field
The present invention relates to steel cord processing technique field, and in particular to a kind of steel wire aramid fiber composite cord.
Background technology
All-steel cord has intensity height, impact resistance, resistance to deformation, thermal conductivity as the main framework material of radial
Can excellent many advantages, but the deficiency such as steel cord is there is also line density is big, endurance and corrosion resistance difference.Aramid fiber is used as one kind
New material, because its light weight, intensity is high, corrosion-resistant etc., excellent performance is just widely used once coming out.
Many tire plants are all studied as the substitute products of novel framework material, but there is also be not easy to rubber for aromatic polyamide cord
Glue bond, resistance to compression are poor, rigidity is low and the bad defect of tire manipulation.
Composite cord is a kind of new cord that the long filament or yarn of unlike material are twisted together, and can be played each
Advantage, obtain a kind of performance more superior rubber framework material.The concept of composite cord is existing in some technical literatures
Related introduction, but the long filament of two kinds of unlike materials is twisted with the fingers together, the problem of still having many.Steel wire aramid fiber composite cord
It there is the problem of two kinds of Materials Fracture elongations are inconsistent, although aramid fiber has high modulus and low fracture to stretch compared with other fibers
Long rate, but compared with the steel cord monofilament for passing through multi pass drawing with high-carbon steel, still there is larger difference.Except part high-modulus
Outside aramid fiber, the elongation at break of most of aramid fiber 2.5~4%, and after wet drawing the elongation at break of monofilament 1.8~2.2%,
The composite cord so formed can be because steel wire be different with aramid fiber extension at break and does not play the strength advantage of aramid fiber, in outer layer surface
When line steel wire reaches maximum intensity fracture, the intensity of the intensity of core aramid fiber at this moment only has the 60~70% of maximum intensity, and
Once cover wire is broken, the load that core aramid fiber is born will be reduced and be broken rapidly so that the rupture strength of whole cord
Have a greatly reduced quality.
Patent CN 102123877A disclose a kind of mixing cord for tire reinforcement, and it is by aramid yarn
Core and steel wire crust composition, the technology employs to solve the problem of two kinds of different materials elongation at breaks are inconsistent
The long filament of high-modulus para-aramid does cored wire, and requires that the long filament has the modulus more than 6.5 newton/dtex, that is, selects
Select the contraposition that standard is also described in the elongation at break high-modulus para-aramid consistent with steel wire fracture elongation, text
When aromatic polyamides makees mixing cord core, the utilization rate of core aramid fiber intensity is about 50%, but this make it that most aramid fiber is fine
Dimension can not all be used.
The content of the invention
To solve the deficiencies in the prior art, it is an object of the invention to provide a kind of intensity height, light weight, add just
Degree, also with higher elongation at break, and improves the fatigue behaviour of the bond properties between steel wire and rubber and cord
Steel wire aramid fiber composite cord.
In order to realize above-mentioned target, the present invention is adopted the following technical scheme that：
Steel wire aramid fiber composite cord, including aramid fiber core and outer layer metal, aramid fiber core include many twisted aramid fibers together
Line, the elongation at break of aramid line is 2.5~4%, and outer layer metal includes many upper thread steel wires, the elongation at break of upper thread steel wire
For 2.5~4%, outer layer metal is wrapped in the outer layer of aramid fiber core, and both are twisted together, and the lay pitch of upper thread steel wire is 8~18mm.
Preferably, the density of foregoing aramid fiber core is 1000D~5000D.
More preferably, the quantity of foregoing aramid line is 1~3, and its specification is 840D × 2,1000D × 2,1000D × 3
Or one kind in 1500D × 2.
It is highly preferred that the sth. made by twisting of foregoing aramid line is to being that S sth. made by twisting or Z are twisted with the fingers, its twist is 50~180 sth. made by twisting/m, too big twist meeting
The intensity of aramid line is reduced, and elongation at break is become big.
It is further preferred that the quantity of foregoing upper thread steel wire is 1~15, upper thread steel wire by carbon content 0.70~
The 0.92% special wire rod of steel cord is after drawing, heat treatment, plating and wet drawing processing, then carries out pre-treatment and make
, plating rear wires steel wire is brass, and copper zinc ratio is 63.5% ± 2.5% or 67.5% ± 2.5%.
Specifically, foregoing upper thread steel wire is wave structure.
Preferably, foregoing upper thread gauge of wire is 0.175~0.38mm, and its wavelength is 10~25 times of diameter, wave height
For 1.2~2.5 times of diameter, because steel wire aramid fiber composite cord is layer structure, core and skin only have two layers, if upper thread steel wire
Diameter is too thin, the reduction of cord rigidity, tire manipulation reduction；If upper thread steel wire diameter is too thick, the single upper thread steel wire of one side
The too high fatigability reduction of rigidity, another aspect cord integral diameter overstriking weight is increased.
More preferably, the sth. made by twisting of upper thread steel wire to be S twist with the fingers or Z twist with the fingers.
The present invention is advantageous in that：
(1) present invention is that many steel wires are wound in the outside of one or more strands of aramid fibers, and then twisting is formed together, is being retained
While the characteristics of aramid fiber intensity height, light weight, the rigidity of cord is added, also allows steel cord to bear higher fracture
Intensity；
(2) by after upper thread copper wire electroplating surface, the fatigue of the bond properties and cord between steel wire and rubber is improved
Performance, and the contact portion between adjacent wires is avoided during long-term use because of mutual extrusion abrasion, then cause tired
The problem of labor declines；
(3) strike-through between upper thread steel wire can be increased, the contact between adjacent wires is reduced.

Detected, testing result is shown in Fig. 2, testing result, which is shown in Fig. 3, to be detected to the elongation at break of steel wire aramid fiber composite cord.
As seen from Figure 2, the rupture strength that aramid line can bear is apparently higher than steel wire, the Breaking elongation one of steel wire
As not more than 2.2%, but can to adjust Breaking elongation by adjusting deflection consistent with aramid fiber for deforming steel wire, thus
Invention carries out pre-degeneration processing to steel wire.As seen from Figure 3, steel wire aramid fiber composite cord for deforming steel wire in phase
The rupture strength that can bear under same elongation at break is significantly increased.
Steel wire and the composite cord of aramid fiber that the present invention is provided, are that, using aramid fiber as core, steel wire is the layer structure curtain of upper thread
Line, i.e., wind many steel wires, then twisting is formed together in the outside of one or more strands of aramid fibers.The steel wire aramid fiber of the present invention is combined
While cord is the characteristics of the intensity height of aramid fiber, light weight is retained, the rigidity of cord is also add, at the brass plating of steel wire
The reason bond properties excellent to improve itself and rubber, bigger effect is the fatigue behaviour of raising cord, it is to avoid steel curtain
Contact portion between line adjacent wires during long-term use because of mutual extrusion abrasion, what the fatigability then caused declined
Problem；Also, the present invention changes steel cord structure, the strike-through between its steel wire is added, is reduced between adjacent wires
Contact so that steel cord has lighter weight and can bear higher fracture strength.
