Polyurethane elastomer material for belt spraying repair

Thread Content

The polyurethane elastomer material used for belt spraying repair is a material with high cohesive energy and excellent wear resistance; compared to natural rubber, its wear resistance can be increased by 2 to 10 times. At the same time, it possesses high mechanical strength and tear strength. Coupled with its excellent shock-absorbing properties, this gives it the ability to overcome harder materials through flexibility. Although it does not have the high hardness of steel or certain plastics, it performs better than steel in applications that require wear resistance. For example, when sandpaper is used to rub polyurethane rubber and other materials, its wear rate is 6 to 7 times that of iron; however, in wet friction processes involving liquid media such as water or oil, the wear resistance of polyurethane rubber is significantly better than that of other materials. Polyurethane elastomer material for belt repair, suitable for addressing rubber damage in various conveyor belts, such as surface damage, cracks, and non-penetrating longitudinal tears in steel-cord conveyor belts, as well as for repairing large-scale damage to conveyor belts. For its repair, rubber components suitable for NR/SBR/IR/BR are selected ； The repair composite adhesive used contains no solvents, allowing it to reach operational strength quickly after repair; there is no need to wait before starting use ； After repair, it maintains stable chemical properties and excellent wear resistance, ensuring long-lasting durability. I. Product Advantages 1. Ready for use immediately, reducing downtime and improving work efficiency. The strength after repair meets the usage requirements, eliminating the need to wait for curing time. 2. The repair technology is reliable, offering a long service life; under normal conditions, it can match the lifespan of the original belt. The filler rubber is a highly wear-resistant rubber produced from natural rubber; it has a high wear coefficient, and its wear resistance is on par with that of the cover rubber on the working surface of the conveyor belt. 3. By utilizing the principle of cold vulcanization, the filling adhesive, under the action of the A+B composite adhesive, fuses with the original belt, thereby preventing delamination and ensuring that no rework is necessary. 4. It is easy to operate, has a simple process, and requires low labor intensity. The vulcanization repair effect can be achieved without large-scale vulcanization equipment. 5. Environmental protection is beneficial to the health of operators. All of TIPTOP’s repair materials contain no harmful substances to the human body such as benzene, formaldehyde, or toluene. 6. An economical repair method with low costs. II. Application Areas 1. Repair of damage to the rubber on the surface of conveyor belts, as well as vertical tears in the rubber. 2. Repair of rubber sealing components (such as hatch seals on ships). 3. Filling of joints after applying rubber lining to their surfaces. 4. Filling of V-shaped joints at areas where drums are covered with rubber. 5. Aesthetic repair of rubber components. 6. Conveyor belt repair process 7. Local damage 8. Cold joints in conveyor belts, steel belt joints 9. Adhesion of rubber to steel, as well as rubber to rubber, and rubber to conveyor belts
