The invention relates to the application field of production and manufacturing industries of tires, automobiles and the like, and discloses tread rubber of a five-composite-tread different-rubber structure and a tire of the tread rubber. The tread rubber comprises tread rubber, base rubber, conductive rubber and tire shoulder rubber, and the tread rubber and the base rubber are sequentially arranged from outside to inside to form a tread layer; the tread rubber comprises middle tread rubber and shoulder tread rubber, the shoulder tread rubber is arranged on the two transverse sides of the middle tread rubber, the middle tread rubber is made of a low-rolling-resistance rubber composition, the shoulder tread rubber is arranged on the two transverse sides of the tread layer, and the conductive rubber is located in the center of the tread layer and penetrates through the middle tread rubber and the base rubber from outside to inside. Rolling resistance, wear resistance, braking and control are controlled through two different tread rubber combination modes on the inner side and the outer side, the tire which is low in rolling resistance, high in wear resistance and good in braking performance and control performance can be provided after vulcanization, the lagging loss of the shoulder of the tire can be effectively reduced, and meanwhile the wet land grabbing performance of the tire is considered.
本发明涉及轮胎、汽车等生产制造行业的应用领域,公开了一种五复合胎面异胶结构的胎面型胶及其轮胎,该胎面型胶包括胎面胶、基部胶、导电胶和胎肩胶,胎面胶和基部胶依次由外向内侧设置构成胎面层,所述胎面胶包括中间胎面胶和肩部胎面胶,肩部胎面胶设置在中间胎面胶的横向两侧,中间胎面胶采用低滚阻橡胶组合物,胎肩胶设置在胎面层的横向两侧,导电胶位于胎面层的中心,导电胶由外向内贯穿中间胎面胶和基部胶。通过两种内外侧不同的胎面胶组合形式来控制滚阻、耐磨性、制动和操控,硫化后可以提供低滚阻、高耐磨、制动性能、操控性能好的轮胎,能够有效降低轮胎肩部滞后损失的同时兼顾轮胎湿地抓着性能。
