Technical field
The present invention relates to rubber item field, be specifically related to a kind of very-high performance tire tread and synthetic method thereof.
Background technology
The aspect ratio of common high-performance tire is higher, and tyre sidewall is long, and impact capacity is strong, and comfortableness is higher comparatively speaking, but feeling of road pavement is poor, and side direction during turning is vulnerable.And when tire aspect ratio is low, internal diameter is large, because tyre sidewall is shorter, tyre surface is broad, thus contact area is large, and the pressure that tire can bear is also large, and road pavement reaction is very sensitive, and during turning, side direction resistivity is strong, by force Vehicle handling.
But when aspect ratio is lower, the contact area on tire and road surface is comparatively large, will inevitably increase tire drag, increase oil consumption.Simultaneously due to the increase of contact area, when ponding road traveling, water cannot be discharged fast, causes the earth-grasping force of tire to decline, and travels dangerous rising.For meeting the requirement of traffic safety, being badly in need of exploitation and a kind ofly there is good over-all properties, the curved resistivity of existing stronger mistake, have again and lowly roll resistance and the superior tire tread of wet earth-grasping force.
Chinese patent 102924771 discloses a kind of high wet-sliding resistant low-rolling-resistance formula, is applied to UHP tire tread, can make that tire tread is wet and slippery reaches B level with rolling resistance simultaneously, but its weak point is that dry ground earth-grasping force is inadequate.
Chinese patent 103408807 discloses a kind of low rolling resistance tyre tread mix, carbon black white carbon black is given part and replaces, add a certain amount of silane coupling agent simultaneously and carry out chemical modification to white carbon black, effectively improve the rolling resistance of tire.But its weak point is that dry ground earth-grasping force is poor with abrasion, can not meet the requirement of UHP tire.
Summary of the invention
The object of this invention is to provide a kind of very-high performance tire tread, it is comparatively strong that it crosses curved resistivity, and rolling resistance is little, saving oil consumption, can also balance wet earth-grasping force and dry earth-grasping force preferably simultaneously, improves wetland driving safety coefficient.
