Tyre

Abstract

The invention discloses a tyre, which comprises (A) tread rubber, (B) tread basal rubber, (C) sidewall rubber, (D) rebate protective rubber, (E) carcass layer rubber, (F) lining layer rubber, (G) triangle rubber, (H) belted layer rubber, (I) air-tight layer rubber and (J) tyre bead steel wire rubber. The tyre components consist of rubber compositions, wherein the rubber compositions of the (A) tread rubber, the (B) tread basal rubber, the(C) sidewall rubber and the (D) rebate protective rubber adopt white carbon black and carbon black with high specific surface area as reinforcing fillers; and the rubber compositions of the (E) carcass layer rubber, the (F) lining layer rubber, the (G) triangle rubber, the (H) belted layer rubber, the (I) air-tight layer rubber and the (J) tyre bead steel wire rubber adopt white carbon black and carbon black with low specific surface area as reinforcing fillers. The tyre has the advantages of good puncture resistance and chunking resistance, low rolling resistance and heat generating performance, and greatly-reduced production cost. The full-steel giant engineering tyre is particularly suitable for an adverse road environment such as a large-scale mine yard.

Description

(1) Technical field: [0001] The invention relates to a tire, in particular to a tire which uses high specific surface area white carbon black and carbon black and low specific surface area white carbon black and carbon black as reinforcing fillers. (two) background technology: [0002] From the perspective of the structure of the tire, its cross section is roughly divided into tread rubber, tread base rubber, carcass rubber, belt layer rubber, sidewall rubber, inner liner rubber and inner liner rubber. Due to the different roles played by the rubber materials in various parts, different rubbers, reinforcing fillers and auxiliary agents can be selected to make them. Carbon black is a reinforcing filler commonly used in the rubber industry, but its heat generation is relatively large, which is easy to make tires Aging, in order to reduce the heat generation of tires and avoid premature aging of tires, many manufacturers have used white carbon black to replace part or all of ca...

Problems solved by technology

In 1992, Michelin took the lead in manufacturing the "green tire" with high specific surface area silica, its rolling resistance was about 30% lower than that of ordinary tires, and the effect of saving fuel and reducing automobile exhaust gas was remarkable. The dispersion is not good, and the tread rubber with white carbon black has lower rolling resistance than that with carbon black, but its wear resistance is much worse than that with carbon black.
