Description
Technical field
The present invention relates to the preparation methods of the high-dispersion white carbon black of a meridian line tyre.
Background technology
Radial is that body cord is arranged by meridian direction, there is cord circumferential array or delaying close to circumferential array
It rushes layer and tightly binds round a kind of novel tire on carcass.Radial makes stress improve, than oblique line wheel because scientific and reasonable for structure
There are many excellent performances for mould:
（1）Service life is long.Due to having rigid larger belt between radial tire tread and casingply,
Therefore for tire when being rolled on road surface, circumferential deformation is small, and Relative sliding is small.Again because the radial elastic of tire body is big, tire is made to connect
Ground area increases, and pressure reduces, therefore tread wear is strong, and resistance to puncture, is not easy to blow out, mileage travelled is than common diagonal-ply tire
More 30%.
（2）Rolling resistance is small, and oil consumption is low.Since radial curtain cloth layer is few, traveling temperature is low, rapid heat dissipation, and because
Circumferential deformation is small, therefore rolling resistance is smaller 15%-20% than common oblique line tire, therefore coasting distance more 25% or so, uses meridian
The travel speed of automobile not only can be improved in tire, and automobile fuel ecomomy also can be improved（Oil consumption 5%-12% can generally be reduced）.
（3）Large carrying capacity.Since the arrangement of radial cord is consistent with the main deformation direction of tire, thus make curtain
Line intensity obtains sufficiently effective utilization, therefore higher by 10% or more than common diagonal-ply tire bearing capacity.
（4）Damping performance is good.It is radial because the radial elastic of radial ply tire is big（Perpendicular to ground direction）Deformation is big, can
To mitigate the impact of uneven road surface, make automobile hold under the arm it is pliable improved, ride comfort, while also reducing vehicle and being hit damage
Possibility, contribute to extend vehicle service life.
White carbon is a kind of excellent reinforcing agent for rubber product.It is added in radial crown suitable white
Carbon black can improve the performances such as its wear-resisting, durable and resistance to puncture, while can improve the grasp property of tire tread road pavement, reduce and roll
Resistance and dynamic heat build up, the existing precipitated silica product that can meet radial requirement on the market is also less, and
Predominantly imported product.
