Abstract

The invention relates to the technical field of conveyor belts, in particular to a TPU (thermoplastic polyurethane) conveyor belt with excellent electric conductivity and a process for preparing the TPU conveyor belt. The TPU conveyor belt comprises an upper surface layer, a framework layer, a bearing layer and a lower surface layer from top to bottom. A carbon nano-particle layer is arranged on the upper surface of the upper surface layer. The process for preparing the TPU conveyor belt with the excellent electric conductivity includes particular steps of S1, adhering the carbon nano-particlelayer on the upper surface layer and drying the carbon nano-particle layer and the upper surface layer for standby application; S2, adding TPU linings onto the various layers and uniformly smearing the TPU linings; S3, carrying out casting molding on four layers and cooling the four layers; S4, closing the edges of cooled conveyor belts and winding the cooled conveyor belts to obtain the TPU conveyor belt which is a finished product. The TPU conveyor belt and the process have the advantages that the carbon nano-particle layer is arranged on the upper surface of the upper surface layer, and accordingly the TPU conveyor belt can be good in electric conductivity and long in service life.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a TPU conveyor belt with good electrical conductivity and a preparation process thereof. Background technique [0002] With the rapid development of the logistics industry, people have higher and higher requirements for logistics transportation equipment. Light conveyor belts are different from other ordinary conveyor belts. They are not only used in various industrial fields such as coal mines, but also widely used in food, medicine, hygiene, and other areas of life that are closely related to people's lives. Therefore, people are concerned about the performance and performance of light conveyor belts The requirements for environmental protection and safety are higher. [0003] The existing conveyor belt has poor electrical conductivity and short service life. Contents of the invention [0004] The object of the present invention is to provide a TPU conveyor belt with...
