Description
Technical field
The invention belongs to automobile tire field of material technology, and in particular to a kind of UHPT tyre surfaces that can be used for drift match
Glue.
Background technology
Tire is the unique parts that automobile contacts with road surface, and among vehicle traveling process, biography is contacted with ground by tyre surface
Pass tractive force or brake force.Car race is always the important motion for promoting tire technology development, and major tyre company is matching
There are larger research and development strength and fund input in tire field.In recent years, automobile drift is matched because of superpower sight at home and abroad
Quickly grow, influence increasingly to increase.Under the attraction of the fast and the furious, the consumer of many kicksters competes to drift to jump
It is intended to try, but expensive luxurious professional race threshold, general public are difficult to go beyond, and some sport cars and refitted car have just adapted to this city
, increasing amateur race is suddenly risen.The drift tire of specialty requires harsh to earth-catching property, handling, but takes turns
The tire life-span typically only tens or hundreds of kilometer, can not compared with common UHPT tires easily up to ten thousand kilometers of distance travelled,
And wet earth-catching property is general, wet-skid road surface driving safety can not ensure, not be suitable for drive routine, and need frequently to change wheel
Tire.And common UHPT tires can not meet the drive demand that drifts about with grabbing with handling, be not suitable for race and use.How to balance
Tire various aspects of performance, make the needs of its race that can meet to drift about is to grabbing ground, handling, can meet drive routine to wheel again
Tire life-span and the requirement of wet earth-catching property, the person that turns into tire working are difficult to a difficult problem overcome.
The content of the invention
The technology being had higher requirements for tire in the prior art to service life (wear hardness) and wet earth-catching property is asked
Topic, it is an object of the invention to provide it is a kind of can be used for drift match UHPT tread rubbers, this patent is exactly that design can be used for
The UHPT tyre surface formulas of amateur drift race.The rubber system of tread rubber from the high-phenylethylene poly- butylbenzene of breast and middle styrene,

Can be balanced.
The UHPT tread rubbers that can be used for drift match that the present invention designs, have selected the solution polymerized butadiene styrene rubber of double terminal groups modifications
With the poly- butylbenzene of breast and rubber system, grab ground, manipulate, wear hardness it is more balanced；Reinforcement system selects SAF and high-ratio surface
Long-pending white carbon and filling system, it is excellent with the rubber system coordinating and unifying, earth-catching property, wear hardness.
Compared with prior art, the present invention has taken into account daily traveling and drift race performance requirement：With common UHPT
Tread rubber is compared, and tread rubber of the present invention is dry, and to grab ground, handling very excellent；Compared with specialty drifts about tread rubber, service life
It is obviously improved, it is wet also to have preferable improvement with grabbing.
Embodiment
The design principle of the UHPT tread rubbers of the match that is used to drift about for the application is described further.
The softer tire of rubber compounding can provide stronger earth-grasping force, but relative abrasion is also very fast.The ground connection of tire
Area adds tire and the area of road surface contact.With the horizontal lifting of tire technology, the perfect and new of design concept is formulated
The application of type elastomeric material has been able to the properties of preferably balance tire, it is met consumer to a greater degree not
With requirement.Rubber system in the application is used in combination from the poly- butylbenzene of high-phenylethylene breast with middle styrene, high-vinyl solution polymerized butylbenzene
The needs of can meeting to drift about race to grabbing ground, handling, high wear hardness can be met again, emulsion polymerized styrene butadiene rubber, contain intermingle with fourth
Benzene rubber is mixed, it is grabbed the dynamic resin of ground low-heat-generation with height and filled by constantly research and development using specific proportions
A large amount of technical oils synergies, make tread rubber grab ground, manipulation, wear hardness are preferably lifted and balanced so that match
The dual-purpose UHPT tread mixs of thing, highway are achieved.
Earth-grasping force can be generally divided into horizontal and vertical earth-grasping force, and the transverse grip refers to the cornering ability of tire, longitudinal direction
Earth-grasping force can be weighed with braking ability or acceleration etc..Meanwhile we can also be commented with the earth-grasping force on wetland and dry ground
Sentence the earth-grasping force of tire.For properties of rubber, dry adherence properties are characterized usually using fissipation factor (tan δ (20 DEG C)) at 20 DEG C
Can, fissipation factor (tan δ (0 DEG C)) characterizes wet earth-catching property at 0 DEG C, and fissipation factor is bigger, and earth-catching property is better.Both are related
Property is verified by formula worker by many experiments.Certainly, more subjective impression experience such as handling, it is exactly
There is provided by most earth-grasping force.For example the grabs ground ability on the common dry ground of Slicks is very powerful, and for wetland phase
To weaker, vice versa.The application of white carbon is nearly all to apply to grab ground field tire is wet in the prior art, and reduces rolling
Resistance, those skilled in the art are difficult that it is fused to dry ground gripping power field well, and it does not reach the grabs ground ability on dry ground,
And the application using super abrasive carbon black and high-ratio surface high-dispersion white carbon black and reinforcement system, high fill can effectively carry
Rise and grab ground and wear hardness.Super abrasive carbon black, it is dry grab ground, manipulation, wear hardness it is excellent, heat is larger；High-ratio surface high dispersive
White carbon, it is dry grab ground, manipulation, wear hardness it is excellent, wet earth-catching property is preferable, and heat is relatively low.Itself and joint with improved dynamic behaviour
The synergy of resin, the thermogenesis performance of tire is maintained at optimum state, be advantageous to reach work faster when drifting about and competing
Make temperature, resin softening, i.e. between 80 DEG C -120 DEG C, tyre surface softens softening point, dry earth-catching property is substantially improved, while can protect
Demonstrate,prove rigidity required during normally travel under tread-rubber normal temperature.On the other hand, the optimization of as above component, the wearability of tyre surface are passed through
More professional can be drifted about one times of tire lifting, suitable with common UHPT tires.
The present invention is further illustrated with reference to specific embodiment.
