Abstract

The invention relates to an all-steel truck radical tire tread rubber, and also relates to an industrial and mineral all-steel truck radical tire using it. The tread rubber includes 100 parts by weight of a rubber component containing natural rubber or containing natural rubber and styrene-butadiene rubber, a filler containing 15-60 parts by weight of reinforcing carbon black and 8-25 parts by weight of high-dispersibility white carbon black, 1-4 parts by weight of a silane coupling agent, 3-9 parts by weight of an activator, 1-6 parts by weight of an antioxidant, 0.5-2.5 parts by weight of a promoter, 1-2 parts by weight of a processing assistant, 0.5-2.5 parts by weight of common sulfur, 1-6 parts by weight of an anti-tear assistant, and 1-3.5 parts by weight of a phenolic tackifying resin. The industrial and mineral all-steel truck radical tire made through using the tire tread rubber well solves a vulcanization speed coupling problem of the industrial and mineral all-steel truck radical tire tread rubber with the rubber compounds of other parts of the tire, and has the advantages of good wear resistance, good fatigue resistance, good tear resistance and good cutting resistance.

Description

technical field [0001] The present invention relates to an all-steel radial tire tread rubber, in particular to an industrial and mining type all-steel radial tire tire with high wear resistance, puncture resistance, cutting resistance, chipping resistance and reduction resistance The tread rubber, and the present invention also relates to an all-steel load radial tire using the tread rubber. Background technique [0002] In recent years, with the development of the global economy, the transportation equipment used in engineering construction and mining production has become increasingly large, which has led to a sharp increase in the demand for carrying tasks undertaken by construction machinery. Due to the harsh conditions of use of the tread rubber of industrial and mining type all-steel load-bearing radial tires, large loads, and many turns, it is easy to be hit, punctured and cut during the contact process between the tread and the road surface. The physical performanc...
