Abstract

The invention discloses an antistatic rubber conveyor belt. The antistatic rubber conveyor belt is used for effectively avoiding adverse effects of static electricity on a material during conveying. The antistatic conveyor belt is formed by an upper layer material, an intermediate layer material and a lower layer material. Each of the upper layer material and the lower layer material is formed bynatural rubber and a small amount of thermoplastic polyurethane filled with acetylene black. The intermediate layer material is formed by a polyester cord material cloth. The antistatic rubber conveyor belt adopting the intermediate layer as a skeleton is obtained by laminating, calendering, vulcanizing and molding the three layer materials. The directed aggregation of the acetylene black in the thermoplastic polyurethane is used to form an effective conductive path, o the effective antistatic effect is achieved under the premise of maintaining the wear resistance of the conveyor belt.

Description

technical field [0001] The invention relates to the field of rubber materials, in particular to a rubber conveyor belt with antistatic properties. Background technique [0002] The rubber conveyor belt is an accessory on the belt conveyor, which can convey materials continuously and efficiently. It is used in electronics, mining, metallurgy, steel, coal, hydropower, building materials, chemical industry, food and other fields. Generally, synthetic fiber dipped canvas is used as the skeleton, and the surface is covered with rubber materials. It is made through the processes of banburying, refining, calendering, molding and vulcanization. [0003] In the process of continuous conveying of materials, the rubber conveyor belt will produce friction with the driving pulley and between materials. This process is prone to static electricity. If the generated static electricity is not discharged in time, it may accumulate. The electric field formed by the accumulated static charg...
