Description
Technical field
The present invention relates to a kind of steel cord being suitable to strengthen elastomer, elastomer for example, rubber passes
Send band, pneumatic tire, rubber hose, rubber synchronous belt and polyurethane synchronous belt.This steel curtain
Line has Open architecture to allow full rubber osmosis.
Background technology
Steel cord with twisted steel filaments is well known in the art, particularly at rubber reinforcement
In field, more particularly in pneumatic tire enhancing field.
A major requirement to steel cord is that the complete of elastomer (such as rubber) permeates.This meaning
Taste rubber and have to be can penetrate between the element of steel cord and fill all possible sky
Gap, to reduce the abrasion between element and stress, avoids dampness to move along steel cord simultaneously, should
Dampness can cause corroding in a large number and can significantly reduce the life-span of steel cord and rubber.
In order to realize full rubber osmosis, prior art provides and makes steel wire deformation and construct open
The solution of steel cord.WO95/16816A1 discloses in the case of not having additional energy
Make the technology that steel wire deforms with becoming polygon.WO99/28547A1 discloses and makes steel wire at two
The technology of curling in plane.WO02/088459A1 discloses and includes first group and the steel of second group
Cord.Twist spirally around first group with the cord lay pitch for this second group.This first group includes
First steel wire of one quantity.First quantity is in the range of between 3 to 8.Second group includes second
Second steel wire of quantity.Second quantity is more than or equal to the first quantity.The lay pitch of the first steel wire is big
In 300mm.At least one in second steel wire is into polygon ground preforming, to allow rubber
Glue penetration.
Although prior art provides several side prepared open steel cord and allow rubber osmosis
Method, but steel cord carries out the deformation of much degree and remains unknown with regard to obtaining full rubber osmosis
's.
Summary of the invention
The primary goal of the present invention is to provide to have and significantly deforms with the steel curtain realizing full rubber osmosis
Line.
The second target of the present invention is to provide for not weakening the steel cord for elastomer enhancing
The steel cord of the full rubber osmosis of energy in the case of processing characteristics and function.
According to the first aspect of the invention, it is desirable to a kind of product of protection, i.e. steel cord includes first
Organizing and second group, twist spirally around first group with the cord lay pitch for second group, first group includes
First steel wire of the first quantity, the first quantity is in the range of between 3 to 8, and second group includes
Second steel wire of two quantity, the second quantity is more than or equal to the first quantity, the lay pitch of the first steel wire
More than 300mm, the first steel wire and all preforming of the second steel wire.Steel cord is in 50N stretching
PLE during power is between 0.08% to 0.25%.It is highly preferred that steel cord stretches at 50N
PLE during tension force is between 0.10% to 0.18%.Second steel wire is when 50N tensile stress
PLE be between 0.9% to 2.0%, between more preferably 1.0% to 1.2%, and first
The steel wire PLE when 50N tensile stress is between 0.4% to 1.0%, more preferably
Between 0.65% to 0.75%.First quantity is 4, and the second quantity is 6.First steel wire preformation
Type is three-dimensional waveform, and this solid waveform preferred has the first curling and the second curling, simultaneously
The plane at the first curling place differs with the plane of the second curling.Second steel wire is that polygon is pre-
Molding.
Accompanying drawing explanation
Fig. 1 describes first preferred embodiment of the present invention.
Fig. 2 shows that the tensile stress of the steel cord for having different PLE and percentage elongation are bent
Line.
Detailed description of the invention
Fig. 1 shows the steel cord combining the present invention, and wherein, steel cord 10 includes first group of steel
Silk 12 and second group of steel wire 14.Second group with length of lay for steel cord around first group spirally
Twisting.First group includes 4 first steel wires 12, and second group includes 6 second steel wires 14.
The lay pitch of the first steel wire 12 is more than 300mm.First steel wire 12 and second steel wire 14 all preformations
Type.Therefore, between steel wire, there is space.
In order to realize full rubber osmosis, the steel cord PLE when 50N tensile stress is 0.08%
Between 0.25%.It is highly preferred that the PLE that steel cord is when 50N tensile stress is 0.10%
Between 0.18%.In the manufacture process of tire, in calendering operation, steel cord is in 8N
To the effect of the tensile stress of 12N, wherein, in calendering operation, steel cord is incorporated into rubber
In gum base body.In order to ensure being constantly present the space for rubber osmosis between steel wire, steel curtain
The line PLE when 50N tensile stress is not lower than 0.08%, because the lowest PLE meaning
In calendering operation opening between steel wire under the tensile stress effect of 8N to 12N can close
Close.On the one hand, although bigger steel cord PLE can bring more preferable rubber permeability, but
The upper limit of steel cord PLE is about 0.25%.Steel cord strengthens thing as tension and is embedded in
In pneumatic tire, and the steel cord that PLE is more than 0.25% means the most open steel cord,
This first can be the most loose and cause trouble in the structure of steel cord due to steel cord；Secondly can be at wheel
Causing trouble in the manufacture process of tire, such as casing ply is coarse or spacing is uneven, and this will cause
The inhomogeneities of tire and the dynamic balancing of destruction tire；3rd, it is impossible in tire, produce foot
Enough intensity, because big PLE means the biggest percentage elongation, and in phase
The steel cord under conditions of Tong with big PLE can not produce and have the steel cord one of little PLE
The intensity of sample.Therefore, the PLE of steel cord should be between 0.08% to 0.25%, more preferably
Ground is between 0.10% to 0.18%.
Based on similar reasoning, in order to obtain preferable steel cord PLE, deposit for steel wire
At upper and lower bound.Second steel wire PLE when 50N tensile stress should be 0.9% to 2.0%
Between, between more preferably 1.0% to 1.2%, and the first steel wire is when 50N tensile stress
PLE be between 0.4% to 1.0%, between more preferably 0.65% to 0.75%.Compare
For, the PLE of the second steel wire needs bigger than the first steel wire, to form sky between the second steel wire
Gap, thus realize full rubber osmosis.
The contrast test carrying out 4+6 × 0.30mm steel cord demonstrates above reasoning equally.
Fig. 2 shows that the tensile stress of the steel cord for having different PLE and percentage elongation are bent
Line, wherein, line 22 represents the steel cord that PLE is 0.08%, and it is 0.14% that line 24 represents PLE
Steel cord, line 26 represents the steel cord that PLE is 0.25%.These three lines have identical
Slope, because three steel cords have identical elastic modelling quantity；And structural elongation is different, because of
Open difference for steel cord.Therefore, line 22,24 and 26 are parallel to each other and stagger.?
In the case of identical percentage elongation E, line 22 can produce the power of F2, and line 24 can produce F4
Power, line 26 can produce the power of F6.Therefore, the PLE steel cord more than 0.25% can not produce
It is sufficiently used for the power of enhancing by polymer.
In order to compensate the decline from F2 to F4 power caused due to the increase of PLE, permissible
Use high-tensile steel wires or super high-tensile steel wires, even special high-tensile steel wires.
In above-mentioned contrast test, use tensile strength higher than 3800-2000 × d (steel wire diameter
(mm)) high-tensile steel wires of MPa is up to the steel curtain of 175GPa to obtain elastic modelling quantity
Line.
Being three-dimensional waveform by the first preshaping of wire, more preferably this solid waveform has first
Curling and the second curling, the plane at the first curling place is different from the plane of the second curling simultaneously.
Owing to the first steel wire is positioned at the inside of steel cord, and do not twist or with the sth. made by twisting more than 300mm
Away from twisting, therefore the three-dimensional waveform on the first steel wire guarantees to be constantly present sky between the first steel wire
Gap is to realize full rubber osmosis.
