Description
Technical field
The present invention relates to a kind of metal cords, the rubber tyre for including the metal cords is further related to.
Background technology
It is well known that enhancing rubber product, especially tire product using steel cord, it is widely used general." height extends steel
Cord " is generally used for enhancing tire zero band and protective layer as one of steel cord family member.It is so-called that " height extends steel
Cord ", the fracture elongation for generally referring to steel cord are not less than 5%.Fracture elongation（δ）It is the finger for describing material plasticity performance
One of mark.The percentage of the total deformation Δ L of gauge length section and the ratio between former gauge length L after fracture elongation, that is, sample tension failure：δ
=ΔL/L×100%.The fracture elongation of steel cord includes the structural elongation of steel cord itself, for example, for " height extends steel
Cord ", when sample stretches first, measure acquisition at first is the structural elongation of the steel cord structure itself, when the structure
After elongation percentage reaches a certain level, just enter the deformation stage of material itself, final sample tension failure, measuring overall result is
The fracture elongation of the steel cord.
In rubber tyre preparation process, especially prepare comprising the rubber wheel by the high nullity belt for extending steel cord enhancing
When tire, it is desirable that the structural elongation that the height extends steel cord is also bigger, otherwise tire can be caused to go out in Vulcanization Process of Rubber
Existing delamination.Currently, widely used tradition is high to extend steel cord 3 × 7 × 0.20mm of structure, it is often used as rubber wheel
The reinforcing element of tire nullity belt.The structure has larger strand spiral angle and cord spiral angle（20.37°/20.84°）, to reach
To higher structural elongation and fracture elongation（2.25%/7.17%）.But the traditional structure not can solve rubber
Strike-through problem, often leading to steel cord cannot be covered by rubber well, eventually lead to the serious corrosion of steel cord itself, pole
The big service life for affecting rubber tyre.Therefore, it finds one kind and being provided simultaneously with high fracture elongation and high structural elongation
The steel cord for meeting full strike-through characteristic simultaneously, is current problem to be solved.
On the other hand, when facing some special rubber tyre preparation processes, such as the preparation of ultra-wide tire.It is well known that
The nullity belt of ultra-wide tire, has and only single layer steel cord winding is used as reinforcing element, extends steel as the high of reinforcing element at this time
Cord must have king-sized structure extension could avoid delamination well.As described above, traditional high extension steel curtain
The structural elongation of 3 × 7 × 0.20mm of cable architecture（2.25%）The preparation requirement of ultra-wide tire cannot be met, if by continuing to do
Big strand spiral angle and cord spiral angle are to obtain higher structural elongation, then steel cord is easily broken, even if by sheer good luck not
Fracture, the mechanical performance of steel cord itself, such as fatigue, rupture pull force are also greatly affected, and service life is had a greatly reduced quality.Cause
This, how under the premise of keeping smaller strand spiral angle and cord spiral angle, be made meet demand, there is more big structure to prolong
The steel cord of rate is stretched, for example, steel cord of the structural elongation more than 3.0% and current problem to be solved.
Invention content
One of the object of the invention is to provide a kind of metal curtain of high fracture elongation and high structural elongation and full strike-through
Line.
Another object of the present invention is to provide a kind of gold including high fracture elongation and high structural elongation and full strike-through
Belong to the rubber tyre of cord.
The first purpose according to the present invention, the technical scheme is that：A kind of metal cords press cord by multiple strands
Lay pitch twisting forms, and each strand is formed by multiple wires by strand lay pitch twisting, the extension of the metal cords
Rate is not less than 5%, and the strand has strand spiral angle, the metal cords to have cord spiral angle, wherein when the strand spiral angle
When with cord spiral angle adduction being 20 °~29 °, the structural elongations of the metal cords of gained is not less than 2.0%；When the stock
When spiral angle of restricting and cord spiral angle adduction are 30 °~38 °, the structural elongation of the metal cords of gained is not less than 2.5%；When
When the strand spiral angle and cord spiral angle adduction are 39 °~48 °, the structural elongation of the metal cords of gained is not less than
3.0%。
Preferably, the structural elongation of the metal cords is not more than 4.0%.
The calculation of strand spiral angle and cord spiral angle is as follows：
Strand spiral angle is α,
Wherein " d " is filament diameter, and " Ls " is the strand lay pitch, and " n " is the quantity for including monofilament in each strand；
Cord spiral angle is β,
Wherein " d " is filament diameter, and " Lc " is the cord lay pitch, and " m " is the quantity for including strand in cord, and " n " is each
Include the quantity of monofilament in strand.
Currently, traditional high metal cords that extend can be made by a series of effective method：Reduce general
The lay pitch of logical metal cords either increases the diameter of wire or increases the quantity of wire strand, in one word, root
According to above-mentioned spiral angle formula, that is, increase the spiral angle of metal cords, to obtain high extension metal cords.But the twirl of metal cords
Angle nor can without limit it is increased, have certain limitation.The spiral angle increase of metal cords will be led to a certain extent
Cause the fracture of metal cords；Even if metal cords are not broken, the continuous increase of metal spiral angle at any time, the machinery of metal cords itself
Performance, such as fatigue, rupture pull force etc. also can drastically decline, and seriously affect the service life of metal cords.
Different from traditional metal cords production technology, the present invention provides another side for obtaining high extension metal cords
Method.The metal cords structure of the present invention is more open, is located at the gap bigger between wire between strand in metal cords, breaks
Split elongation percentage and structural elongation higher（Under the premise of not changing spiral angle size）, simultaneously because the increase in gap, metal curtain
The strike-through performance of line is greatly improved, and meets complete strike-through performance.
