Abstract

The invention relates to an energy-saving high strength aramid fiber conveyer belt and a preparation method thereof. The conveyer belt is composed of a skeleton layer, adhesive glue and an upper-lower cover adhesive laminated structure. Firstly, the skeleton layer employs aramid fiber canvas after dipping treatment to replace a conventional steel wire rope, so that the problems of large weight of the steel wire rope which brings much inconvenience for processes of shaping, installing, maintaining and the like is solved. Secondly, the aramid fiber canvas has structure in broadwise direction, has excellent anti-tear and anti-impact performances, so that phenomena of longitudinal tear and the like of the steel wire rope conveyer belt cab be prevented. Compared with a conventional steel wire rope high strength conveyer belt, the energy-saving high strength aramid fiber conveyer belt has high strength, good corrosion resistance, wear resistance and impact and fatigue resistance, and greatly reduce the weight and thickness of the conveyor belt, so that conveying power energy consumption is saved. The energy-saving high strength aramid fiber conveyer belt is expected to have longer service life and better energy-saving and environment-friendly properties, and is particularly suitable for long-distance material conveyance in industries such as coal mine, metallurgy, mine, etc.

Description

technical field [0001] The invention relates to an energy-saving high-strength aramid conveyor belt and a preparation method thereof, which is especially suitable for long-distance material transportation in industries such as coal mines, metallurgy, and mines, and belongs to the technical field of rubber products. Background technique [0002] Rubber conveyor belt is the second largest category of important rubber products after tires, and belongs to the field of petrochemical industry. High-performance conveyor belts are mainly used in key national industries such as coal, metallurgy, building materials, coke, and power generation that support national economic and social development, and the annual growth rate of demand exceeds 25%. my country is the world's largest producer of conveyor belts, but foreign products are still monopolized in high-end application fields and high-end customer groups, earning huge profits with high added value. With the continuous development ...
