The conveyor belt plays a role in traction and load carrying in belt conveyors; it is the main working component of the conveyor, and its motion state determines the continuity and stability of material transport by the conveyor. During operation, frictional wear occurs between the conveyor belt and rollers, idlers, as well as the material itself. According to information from the mine site, belt wear occurs on both the load-bearing surface and the non-load-bearing surface. To extend the service life of the conveyor belt, it is first necessary to find ways to minimize friction on the belt, especially sliding friction ； Secondly, when selecting the material for the conveyor belt, it is necessary to choose a material with low friction and high wear resistance. However, during mechanical operation, frictional wear of the conveyor belt is inevitable. The cost of replacing the conveyor belt is high; therefore, to save costs, the worn belt can be repaired. By using repair materials with excellent adhesive properties, the conveyor belt can be restored to its original condition, and friction between the original belt material and the idlers can even be reduced, thereby maximizing the service life of the conveyor belt. The two types of 100% solid-based, shrink-resistant polyurethane repair materials are available in paste form and are packaged in cans or other containers suitable for use on site. This repair material is highly effective for repairing damages in products with elastic properties such as rubber, polyurethane linings, conveyor belts, and pulley insulations. Polyurethane repair materials are room-temperature curing, solvent-free polyether adhesive types ； It features fast curing speed, simple operation, ease of use, good filling properties, being non-toxic and odorless, resistance to media, aging resistance, high bonding strength, and high insulation strength ； After curing, it exhibits high toughness, wear resistance, corrosion resistance, as well as excellent resistance to impact wear and cavitation. The polyurethane adhesive repair material series features excellent adhesion properties; different primers and adhesives are available depending on the substrate, ensuring that there is a suitable primer and adhesive for all metal and non-metal substrates. After being mixed in the proper proportions, polyurethane repair material can be applied to form coatings of any thickness. Since the material contains no volatile components, the coatings do not shrink. The cured surface can be machined or polished to achieve a relatively smooth surface. These features make it easier to achieve a smooth repair surface that is consistent with that of the original substrate when carrying out surface repairs using polyurethane repair materials. Polyurethane repair materials can be used to address a wide range of repair issues related to elastomers. They are primarily employed for sealing and repairing longitudinal and transverse tears in rubber products, as well as in steel-reinforced products and conventional conveyor belts, as well as for creating elastic joints ； Repair of surface wear, defects, chipping, edge wear, and perforations on conveyor belts, as well as sealing of joints ； Bonding, insulation sealing, and repair of cables, rubber linings, tires, rubber impellers, rubber rollers, and other rubber products ； It can also be used for the preparation of rubber lining coatings that provide equipment with resistance to cavitation, protection against cavitation, as well as resistance to impact and wear
