Description
Technical field
The present invention relates to rubber field, and in particular to a kind of low rolling resistance tyre tread rubber of super-high wear-resistant performance
Material.
Background technology
Automobile can produce various running resistances in the process of moving, wherein 80% is air drag, remaining is 20% to roll
Resistance.It data show, the CO discharged at present during tire frictional heat2The greenhouse gas of global fossil fuel release is occupied
The 3% of body；Automobile fuel consumption has quite a few to be used to overcome tire frictional resistance.The data of EU Committee show, automotive wheels
Energy consumption needed for tire rolling resistance accounts for 20% of complete-vehicle oil consumption or so.In other words, it is just once complete equivalent to often plus five oil
It is to add for tire.According to surveying and determination, tire drag often reduces by 7%, vehicle fuel consumption is reduced by 1%, while also may be used
So that CO is greatly reduced2Discharge capacity, if using the small tire of rolling resistance, under steam pin step on the degree of gas also with
Reduction, also imply that saving oil consumption.Therefore, the overall energy consumption of vehicle is reduced so as to reach by reducing tire drag
To fuel-efficient purpose.
Common low rolling resistance tire, wet-sliding resistant performance, anti-wear performance etc. are but sacrificed while reduction rolling resistance itself,
So people are studying the relation between rolling resistance (RR), anti-slippery (WSR), anti-wear performance (WR) this three always.Due to
The self performance of this three, it is impossible to while improved, that is, will be while a certain or two kinds of performances are sacrificed
The improvement of another performance can be obtained, this three has the relation mutually restricted.The influence of tire drag is special by material
Property, the factors such as tire construction, tire quality and use condition influence, some of which factor influences each other again, simple drop
Low tire drag is not to be difficult, but generally to sacrifice some performances of tire, particularly wet-sliding resistant performance.And from peace
Full angle sets out, and tire should keep certain wet-sliding resistant performance, so selection material and Design of Tire Structure are to reduce tire
The important channel of rolling resistance.Common low rolling resistance tread rubber, although there is low-rolling-resistance, there is sizing material intolerant to
Mill, the shortcomings of wet-sliding resistant performance is poor, low-rolling-resistance is invented, while keep the tire of good wearability and wet-sliding resistant performance
Face glue formula has great significance for reducing tire drag.
The content of the invention
It is an object of the invention to provide a kind of low rolling resistance tyre tread mix of super-high wear-resistant performance, its anti-wear performance
By force, excessively curved resistivity is stronger, and rolling resistance is small, while also has preferably wet earth-grasping force, ice-snow field earth-grasping force, it is possible to increase wetland
Driving safety coefficient.
To achieve the above object, technical scheme provided by the invention is a kind of low-rolling-resistance wheel of super-high wear-resistant performance

Wherein, the ratio of butadiene rubber and the oil-extended styrene buadiene rubber total amount is 1: 6~1: 7.Under this proportionate relationship, glue
Material can have high abrasion resistance under the premise of superior mechanical performance is kept.
Wherein, the ratio of the oil-extended styrene buadiene rubber SBR1739 and SBR1723 can kept between 1: 5~1: 6
The earth-grasping force performance of sizing material is improved on the premise of superior mechanical performance.
Wherein, the specific surface area of the fine intermediate super abrasion furnace black high structure is 111~121m2/ g, it has very high benefit
Epistasis energy, make the anti-wear performance of sizing material excellent.
Wherein, the high-dispersion white carbon black specific surface area is 130~400m2/ g, it can greatly reduce rolling resistance.
Wherein, fine intermediate super abrasion furnace black high structure and the white carbon ratio is 1: 1~1: 2, can be made in sizing material proportioning
Wear-resisting and rolling resistance Coordination Equilibrium.
The coumarone indene resin COUMARONE RESINCY-CR1 tackifying resins main component is being total to for benzofuran and indenes
Polymers, for the product of catalytic polymerization after kerosene distillate processing, it act as effectively improving earth-grasping force.
Soften tackifier GOYENCHEM-GR80 tackifying resins mainly using rosin and hydrogenated rosin fat as basis
Adhesive, contact adhesive and rubber tackifier, it act as improving sizing material joint viscosity and sizing material transaction capabilities.
Fine intermediate super abrasion furnace black high structure and new modified tackifying resin are used in conjunction with that Mechanical Properties of Products can be greatly promoted,
Improved in mechanical properties.
Silane coupler X-50S is combined with rubber greatly improves stress at definite elongation, tensile strength, dynamic modulus, wearability
Can, while acted on white carbon, low rolling resistance, low-heat-generation, optimal between good earth-catching property and high-wear resistance can be obtained
Balance.
Two kinds of low temperature breasts gather oil-filled butadiene-styrene rubber, butadiene rubber, fine intermediate super abrasion furnace black high structure, high-dispersion white carbon black, thickening
Resin, silane coupler X-50S are combined produce special viscoelastic body rubber together, not only make rubber is anti-slippery can be lifted, and
And greatly improve the anti-wear performance of sizing material.
The present invention also provides a kind of synthetic method of the low rolling resistance tyre tread mix of super-high wear-resistant performance, the conjunction
It is as follows into method：
