Abstract

The invention discloses a rubber composition for engineering tire treads, comprising, by weight, 100 parts of a diene rubber component, 5-100 parts of carbon black, 1-50 parts of silica, and 1-30 parts of modified bisphenol phenolic resin. The rubber composition as an engineering tire tread material has improved aging resistance, tear resistance and wear resistance, with good mechanical propertiesand processibility retained.

Description

technical field [0001] The invention belongs to the field of rubber compositions, in particular to a rubber composition for engineering tire treads and a pneumatic tire using the rubber composition. Background technique [0002] During the use of engineering tires, due to the influence of various complex road surfaces, coupled with the effects of weather and sunlight, the tires age faster, wear increases, and are prone to problems such as block falling, which affects the service life and safety. . [0003] Patent 201410233702.4 discloses a tread rubber for high wear-resistant engineering tires. The tread rubber is mainly natural rubber, and styrene-butadiene rubber is used instead of styrene-butadiene rubber. While resisting chipping and chipping, its wear resistance is improved, so that the service life of the tire is greatly improved. [0004] Patent 201210291865.9 discloses a fully synthetic rubber tread compound for engineering tires, which uses rubber combined with st...
