Technical field
The present invention relates to a kind of rubber for tire technical field, and suitable for high temperature, vulcanization causes the serious work of over cure for a long time
Journey machinery is with the rubber composition of radial ply tyre steel wire cord coating.
Background technology
It is well known that cord-rubber composite (cord and the rubber composition group being coated onto in radial
Into) be tire Main Load bearing carrier, they provide strength and stability for sidewall and tyre surface, and keep air pressure.Steel wire
The bonding force of cord and the rubber composition being coated onto directly influences the performance and service life of radial.
Engineering machinery bears that load is big, and travel speed is slow with radial product, and use environment is severe.To adapt to bear
Top load, the diameter of the framework material of engineering machinery radial, intensity will accordingly increase, to coordinate its skeleton material
Material, the bonding force of corresponding all-steel cord coating rubber composition also strengthen, and modulus increase, off-the-road tyre uses ring
Border is severe, moist, rainy, road conditions are poor etc., and that severe working environment make it that the framework material of off-the-road tyre should also have is heat-resisting
The excellent properties such as oxygen, steam, salt solution aging.Rugged hill path and top load cause off-the-road tyre deformation big, inside tires
Stress is high, therefore its framework material, particularly casingply are flexibility good, prevent from causing rubber composition under the conditions of flexion
Earlier period damage, so as to influence the life-span of tire.Off-the-road tyre belongs to thick rubber products, and the vulcanization of use is generally
High temperature vulcanizes for a long time, and vulcanization causes tire part over cure serious to high temperature for a long time, therefore the steel wire that reversion resistance is good
Fiber-reinforced rubber composition can solve the problems, such as that over cure is serious in sulfidation well.
The content of the invention
The purpose of the present invention is exactly to overcome existing technical deficiency, there is provided a kind of engineering machinery radial tire steel
Silk cord coating rubber composition, have bonding force high, modulus is high, resistance to ag(e)ing is good, it is flexibility it is good, reversion resistance is good
The characteristics of, coated and used with radial ply tyre steel wire cord especially suitable for engineering machinery.
The present invention solves the technical scheme that above-mentioned technical problem uses：A kind of engineering machinery radial ply tyre steel wire curtain
Line coating rubber composition, it is characterised in that：On the basis of the rubber components of 100 parts by weight, also include in parts by weight, in vain
Carbon black 5-20 parts by weight；Cobalt content is the organic acid cobalt salt of 0.03-1 parts by weight；Adhesive resorcinol 0.5-5 parts by weight, or
The mixture of person's resorcinol and adding carrier composition replaces；Adhesive HMMMM 0.5-7 parts by weight, or it is mixed with carrier composition
Compound replaces；The double two parts of crystallization water 1.0-3.0 parts by weight of sodothiol of hexa-methylene -1,6-, or with its carrier
The mixture of composition replaces；1,3- double (lemon acid imide methyl) benzene 0.1-1 parts by weight, or the mixing with its carrier composition
Thing replaces；Insoluble sulfur 2-8 parts by weight；Sulphenamide accelerators DZ0.5-1.5 parts by weight.
Described rubber components be natural rubber, one kind in butadiene-styrene rubber either its mixture or natural rubber with
The mixture of butadiene rubber, or the mixture of natural rubber, butadiene rubber and butadiene-styrene rubber.
The invention has the advantages that high with bonding force, modulus is high, resistance to ag(e)ing is good, flexibility good, anti-recovery
Property it is good the characteristics of, especially suitable for engineering machinery with radial ply tyre steel wire cord coat use.
Embodiment
With reference to embodiment, the present invention will be further described：
The present invention is used for the all-steel cord coating rubber composition of off-the-road tyre, can use following manufacture methods, specifically
Step is as follows：
1. rubber components, zinc oxide, cobalt salt, dispersant, age resistor, organic acid, 2/3 carbon black are put into GK400 type ZZ rotors
In banbury, 40 ± 3 revs/min of rotating speed, it is kneaded 2.5-4min and obtains elastomeric compound A, dump temperature is controlled at 155-165 DEG C.
2. by the carbon black of surplus, white carbon, adhesive SL-3020, phenolic resin, the double thiosulfuric acids of hexa-methylene -1,6-
Double (the lemon acid imide methyl) benzene of two parts of crystallizations water of disodium salt, 1,3- and elastomeric compound A are added to GK400 type ZZ rotor banburies
In, 28 ± 3 revs/min of rotating speed, 2.5-4min is kneaded, obtains elastomeric compound B, dump temperature is controlled at 145-155 DEG C.
3. elastomeric compound B is kneaded 2.5-3min in GK400 type ZZ rotor banburies according to 28 ± 3 revs/min of conditions of rotating speed,
Elastomeric compound C is obtained, dump temperature is controlled at 135-145 DEG C.
3. sulphur, RA-65, accelerator, antiscorching agent and elastomeric compound C are added in GK255 type banburies, 2.5- is kneaded
3min, obtain above-mentioned engineering machinery meridian tyre steel wire cord coating rubber composition.
Organic acid cobalt salt may include cobalt decanoate, cobalt naphthenate, cobaltous octadecanate, cobalt boracylate etc., the isophthalic in binding system
SL-3020, B-20-S or other resorcinols and its carrier can be used in diphenol, and RA-65 or other can be used in adhesive HMMM
HMMM and its carrier.The insoluble sulfur trade mark such as including HDOT-20, IS-7020.
Insoluble sulfur produces chemical adhesion, and rubber in the presence of cobalt salt with brass-plated steel cord in rubber composition
Double two parts of crystallizations water of sodothiol of hexa-methylene -1,6- in composition, 1,3- double (lemon acid imide methyl) benzene with
Adhesive resorcinol, HMMM also with all-steel cord produce chemical adhesion, a variety of bonding modes can repair copper facing it is uneven or
Person's steel wire cutting end points does not cover steel wire bare spots and the bonding of rubber composition of copper, while the double thio sulphur of hexa-methylene -1,6-
Two parts of crystallizations water of acid disodium salt, 1,3- double (lemon acid imide methyl) benzene and adhesive resorcinol, HMMM and white carbon shape
Into a kind of new network structure, the new network structure of formation enhances the modulus of rubber composition；In high temperature long-time sulphur
During change, new cross-bond is constantly formed during use, is alleviated caused by under the conditions of sulfidation medium and high temperature long-time
Molecular chain rupture, so as to slow down while modulus is enhanced rubber composition long-time vulcanize after, large deformation flexion lead
Bonding force under the hot conditions of cause declines, and improves the heat-resisting oxygen of rubber composition, damp and hot, salt solution ageing properties.This is new
Network structure can be blocked to subdue as caused by stress and destroyed, and improve flexion destructive characteristics.Add the double thio sulphur of hexa-methylene -1,6-
Double (lemon acid imide methyl) benzene of two parts of crystallizations water of acid disodium salt, 1,3-, with resorcinol, HMMM interphase interactions and being formed
Network structure, also effectively it can prevent resorcinol from spraying.
