Abstract

The invention discloses a tire rubber material with excellent cooling performance. The tire rubber material is characterized in that in the formula, full-natural rubber is combined with a semi-effective vulcanization system and a reinforcing system, wherein the semi-effective vulcanization system comprises the following commixed components in parts by weight: (1) 2.3-2.8 parts of sulfur and (b) 0.5-0.8 part of an aminodithioformate accelerator; the reinforcing system comprises the following commixed components in parts by weight: (a) 25-35 parts of carbon black, (b) 15-25 parts of white carbon black and (c) 2.2-2.6 parts of a pure-silane coupling agent Si-69.

Description

technical field [0001] The invention relates to the technical field of production of giant all-steel radial engineering tires, in particular to a tire compound with excellent heat dissipation performance. Background technique [0002] Giant all-steel wire radial OTR tires are tires for vehicles transporting materials such as mining in large mines and other places. Since the section of the tread part of the giant tire includes the tread, the base tread rubber, the belt layer, the carcass, the transition layer, and the inner liner, the thickness of the entire section is large, and it is an extremely thick product among rubber products. [0003] The use conditions of giant tires are quite harsh, the load capacity is particularly large, and the size of each part of the tire section is large. During the use of the tire, the rubber inside the tire, especially the rubber at the base of the tread, generates high heat and is difficult to dissipate, which greatly reduces the service l...
