Abstract

The invention relates to a highly anti-static thermoplastic polyurethane (PU) conveyer belt for the textile industry and a preparation method thereof. The upper surface of a facing fabric is sequentially coated with a PU bottom coating, a TPU (Thermoplastic Polyurethane) surface layer and a carbon nano tube modified TPU surface layer from bottom to top, and the lower surface of the facing fabric is coated with a PU bottom coating; a bottom fabric is a fabric containing conductive fibers, and the upper surface of the bottom fabric is sequentially coated with a conductive liquid coating, a PU bottom coating and a TPU laminating layer from bottom to top; and the conductive liquid is a solution of carbon nano tube modified TPU in an organic solvent. The preparation method comprises the following steps of: coating the PU bottom coating, the TPU surface layer and the carbon nano tube modified TPU surface layer on the upper surface of the facing fabric, and coating the PU bottom coating on the lower surface of the facing fabric; coating the conductive liquid coating, the PU bottom coating and the TPU on the upper surface of the bottom fabric and carrying out heat setting to form the laminating layer; and superposing and compounding the fabrics up and down to prepare the conveyer belt. The conveyer belt has the advantages that the surface resistance of the conveyer belt reaches 103 omegas and the bottom resistance reaches 105 omegas, which sufficiently meet the requirement on the textile industry.

Description

technical field [0001] The invention belongs to the textile field, in particular to a high antistatic thermoplastic polyurethane elastomer conveyor belt used in the textile industry and a preparation method thereof. Background technique [0002] TPU (thermoplastic polyurethane elastomer) is an emerging polymer material with high elasticity, high Young's modulus, good flexibility, wear resistance, weather resistance, oil resistance, solvent resistance, environmental protection and other excellent properties. Therefore, it is widely used in ships, vehicles, aviation, light industry, textile and other departments. [0003] The above advantages based on polyurethane materials determine that the conveyor belt made of this material has a wide range of uses in the textile machinery industry that has high requirements for deflection and wear resistance; textile machinery needs high-speed operation due to the transmission device, and the conveyor belt is in friction with the machine....
