Polyurethane logistics conveyer belt and manufacturing method thereof

Abstract

The invention discloses a polyurethane logistics conveyer belt and a manufacturing method of the polyurethane logistics conveyer belt. The polyurethane logistics conveyer belt comprises a middle framework fabric layer, polyurethane adhesive dipped in the middle framework fabric layer and a wear-proof thermoplastic polyurethane elastomer film surface layer. Polyester fiber base fabric is dipped into a polyurethane adhesive solution, dried and shaped, the surface of the polyester fiber base fabric is attached to an extruded thermoplastic polyurethane elastomer film, polishing treatment and other processes are conducted on the back face of the polyester fiber base fabric, and then the polyurethane logistics conveyer belt is manufactured. The conveyer belt is an open conveyer belt, and steel buckle flocking connectors are adopted. Compared with the prior art, the polyurethane logistics conveyer belt has the excellent properties of being low in mass, low in energy consumption, resistant to wear, free of burrs, resistant to low temperature and the like. Especially, flocking is conducted at the positions of the steel buckle connectors, steel buckles and a rolling wheel can be prevented from generating friction damage, and the service life of the conveyer belt is prolonged.

Problems solved by technology

[0003] Polyurethane logistics conveyor belt is a kind of composite material conveyor belt with excellent processing performance and mechanical strength made by dipping process. The temperature in northern China is low in winter. There are great shortcomings in terms of weight, wear and tear, low temperature resistance, etc., and when running at low temperature in winter, the belt bone becomes hard, resulting in a larger turning diameter and increased turning stress, which cannot eliminate the problem of running deviation and edging; at the same time Traditional conveyor belts have heavy weight, high wear, low service life, high corresponding energy waste, and low transmission efficiency, which do not meet the current theme requirements of green energy conservation and environmental protection in China and the world.

[0004] The Chinese invention patent with application number 201410217584.8 discloses a kind of impregnated PVC conveyor belt for the logistics industry and its manufacturing method. The conveyor belt includes a fabric skeleton structure and a coating. And the fabric is impregnated with PVC layer, and the joint is gear joint; during preparation, the composite polyester fabric woven by double warp beams is shaped, impregnated with PVC, rolled, plasticized and dried, and the surface is finished until the surface is smooth. The logistics conveyor belt is heavy and has high wear and tear. In a low temperature environment, especially in an environment of -30°C~-40°C, such as winter in Northeast China, the surface hardness will increase sharply during use, and the turning diameter will increase by about 100%. Above, the surface of the conveyor belt has cracks, edge wear and fluffing and other undesirable phenomena, resulting in the peeling off of the surface coating of the conveyor belt and a serious shortening of the service life; based on the above reasons, it is necessary to improve the technology of the polyurethane logistics conveyor belt of the prior art to meet its use requirements
