Tyre tread rubber composition used in hard mine area and production method of tyre tread rubber composition in hard mine area

Abstract

The invention relates to the technical field of rubber, in particular to a tyre tread rubber composition used in a hard mine area and a production method of the tread rubber composition in the hard mine area. The tyre tread rubber composition comprises the following materials by weight: 50-90 parts of styrene butadiene rubber, 10-50 parts of natural rubber, 45-55 parts of carbon black, 15-25 parts of white carbon black, 2-5 parts of zinc oxide, 1-3 parts of stearic acid, 2-4.5 parts of silane coupling agent, 2-5 parts of cutting resistant resin, 10-20 parts of aromatic oil, 1-3 parts of antioxidant N-(1,3-dimethylbutyl)-N'-phenyl p-phenylenediamine, 1-2 parts of antioxidant 2, 2, 4-trimethyl-1,2-dihydroquinoline polymer, 1-3.5 parts of microcrystalline wax, 1-2 parts of sulfur, 1.0-2.0 parts of vulcanization accelerant N-tertiary butyl-2-benzothiazole sulfonamide, 0.5-1.0 parts of vulcanization accelerant N,N-diphenylguanidine and 0.1-0.3 parts of scorch retarder. The tyre tread rubber composition used in a hard mine area and the production method provided by the invention can obviously improve puncture resistant property, the chipping resistant property, the safety and the service life of a tyre in the hard mine area.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a tire tread rubber composition used in hard mining areas. Background technique [0002] As we all know, radial truck tires have the advantages of wear resistance, fuel saving, and long service life. type design. In traditional technology, the raw rubber system in the tread rubber of radial truck tires is mainly natural rubber, and the filler system is mainly high-structure carbon black N234. This formula is suitable for high-speed and ordinary road conditions. When applied to mining area roads, especially On hard mining roads such as iron and molybdenum, the tire tread rubber is not resistant to puncture, the tread rubber is easy to fall off, and the tearing performance of the rubber material is poor. In severe cases, the tire crown bursts, and the tire safety performance is low. The service life is short, and traditional products obviously cannot meet the current requirements...
