Abstract

The present invention relates to one kind of tearproof antiwear conveying belt, and belongs to the field of rubber product technology. The tearproof antiwear conveying belt is produced through pre-pressing and mixing natural rubber, styrene butadiene rubber and cis-butadiene rubber inside a Banbury mixer; adding promoter, activator, leveler and antiaging agent before further mixing; adding reinforcing agent, softening agent and aramid fiber before further mixing to obtain mixed rubber; mixing for the second time and adding cross-linking agent inside a Banbury mixer after being set for some time; discharging batch to obtain mixed rubber; rolling to form rubber sheet; combining rubber sheet with tension element belt blank, rolling up and sulfurizing; and trimming to obtain the product. The tearproof antiwear conveying belt has excellent tearproof performance, excellent antiwear performance and long service life, and is suitable for use in mines.

Description

technical field [0001] The invention relates to a tear-proof and wear-resistant conveyor belt, in particular to the operation conveying of large blocks of ore in mines, and belongs to the technical field of rubber products. Background technique [0002] Tear-resistant and wear-resistant conveyor belts are widely used in the operation and transportation of iron ore, copper ore, quarry and other minerals. In recent years, my country's economy has grown rapidly, and the domestically developed mineral resources have been in short supply, which has driven the large-scale mining and utilization of mining resources (iron ore, copper ore, quarry, etc.). After blasting and coarse crushing, the ore material is transported to the next operation area by the conveyor belt. At this time, the ore material has many lumps above 500mm and the weight is about 100Kg. Therefore, the own weight of the mineral material, the sharp shape of the mineral material, and the high drop cause great impact...
