Abstract

The invention discloses a wear-resistant tire tread rubber material for an ultra-long driving mileage. The wear-resistant tire tread rubber material comprises a tread rubber material, wherein 0.40-0.60 wt% of crude rubber and 0.30-0.45 wt% of a reinforcing material are also dispersed in the tread rubber material, and specifically the tread rubber material comprises the following raw materials in parts by weight: 100.0 parts of rubber, 50.0 to 80.0 parts of a reinforcing filler, 3.0 to 8.0 parts of an active agent, 0.5 to 4.5 parts of an anti-aging agent, 1.0 to 2.5 parts of protective wax, 2.0to 15.0 parts of rubber processing oil, 1.2 to 3.5 parts of sulfur, 0.8 to 3.5 parts of an accelerant, and 0.1 to 0.4 part of scorch retarder. According to the wear-resistant tread rubber disclosed by the invention, unique raw rubber and a reinforcing system are adopted, so that excellent wet skid resistance and ultra-long mileage can be provided in the whole life cycle of a tire, and the formulais flexible in design, the raw material selection range is wide, the processing process is not limited by the type of an internal mixer, and the quality is stable.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a tire wear-resistant tread rubber material for super long driving mileage. Background technique [0002] Due to the demands of domestic and foreign taxi markets, wear-resistant tires have always occupied an important market segment. Mainstream wear tires can suffer from insufficient wet grip, especially in rainy areas. The development of wear-resistant tire tread compounds focuses on improving the tire's wet grip without compromising mileage. [0003] Usually, in order to meet the long mileage of the tread compound, the amount of butadiene rubber and reinforcing agent will be increased in formula design, but the ensuing problem is the reduction of wet skid performance. In order to meet the long mileage and wet performance requirements of wear-resistant tires, a unique design of the tread formula is required. Emulsion or solution polystyrene-butadiene rubber, high-bu...
