Problems solved by technology

[0003] After foaming, TPU particles are full of elasticity, very light in weight, and have a volume expansion of 5-8 times, which overcomes the heavy weight, high hardness and poor shock absorption performance of TPU particles At the same time, it is lighter in weight, more breathable, environmentally friendly, wear-resistant, high-elastic, and yellowing-resistant. It is widely used in the insole material industry, but it has not been used in the field of conveyor belts.

Abstract

The invention discloses a steel plate conveying belt for conveying metal plates. The steel plate conveying belt is of a two-cloth two-glue structure and comprises a conveying belt upper layer part and a conveying belt lower layer part which are formed by laminating a solvent-free two-component polyurethane glue, wherein the conveying belt upper layer part is formed by compounding a high-strength fabric framework coated with a PU glue, a TPU coating layer and a silicon sulfide modified TPU thermoplastic resin coating layer, and the conveying belt lower layer part is formed by compounding a high-strength fabric framework coated with a PU glue and a foaming coating layer. The invention further discloses a preparation method of the steel plate conveying belt for conveying metal plates. According to the invention, the thickness of the two-cloth two-glue conveying belt can reach 3.5-6 mm, and compared with an existing steel plate conveying belt needing three to five times of coating attaching, the conveying belt is high in production efficiency and small in loss.

Description

technical field [0001] The invention relates to the technical field of conveyor belts, in particular to a steel plate conveyor belt used for conveying metal plates and a preparation method thereof. Background technique [0002] At present, most of the steel plate conveyor belts used for conveying metal plates in the processing of automobiles, steel plates, and aluminum plates use polyester composite fabrics as the load-bearing skeleton, coated with polyurethane (TPU) resin as the loading surface, and the thickness is usually 3-6mm. It is necessary to laminate the polyester composite fabric coated with TPU resin in multiple layers, at least three times, or even five times, resulting in low production efficiency, increased thickness of lamination in the later stage, increased difficulty of lamination, and low strength. If it does not meet the requirements for use, it needs to be reprocessed or discarded. In addition, during the steel plate conveying process, steel plates, iro...
