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 an anti-tearing and wear-resistant conveyor belt, in particular it is used for operation conveying of bulk mineral materials in mines, and belongs to the technical field of rubber products. Background technique [0002] Anti-tearing and wear-resistant conveyor belts are widely used in the operation and transportation of iron ore, copper ore, stone ore and other mineral materials in mines. In recent years, my country's economy has grown rapidly, and the domestically developed mineral resources are in short supply, which has led to the large-scale exploitation and utilization of mine resources (iron ore, copper ore, quarry, etc.). After blasting and coarse crushing, the mineral material is transported to the next operation area by the conveyor belt. At this time, the mineral material has a block size of more than 500mm and a weight of about 100Kg. The drop of the mineral material on the conveyor belt is 1-5M. Therefore, the own ...
