However, during the use of light PVC conveyor belt, the wear resistance and low temperature resistance are poor, especially in the north, the surface of the conveyor belt will be brittle and worn, which will reduce the mechanical properties of the conveyor belt and affect its service life
The traditional coating method is used to prepare light PVC conveyor belts, and a large amount of plasticizer fumes will be generated during the preparation process, polluting the environment

Abstract
The invention discloses a wear-resistant cold-resistant modified polyvinyl chloride (PVC) / thermoplastic polyurethane elastomer (TPU) composite lightweight conveyor belt. The conveyor belt is formed by pressing a fiber fabric and a PVC / TPU composite clad material, the PVC / TPU composite clad material comprises the following components in parts by weight: 100 parts of PVC powder, 10-40 parts of TPU powder, 60-70 parts of dioctyl phthalate, 4-6 parts of epoxidized soybean oil, 2-4 parts of calcium-zinc composite heat stabilizer and 5-10 parts of ground calcium carbonate, so as to prepare the wear-resistant cold-resistant modified polyvinyl chloride (PVC) / thermoplastic polyurethane elastomer (TPU) composite lightweight conveyor belt. Because the compatibility of the polyester type TPU and the suspension type PVC of the composite clad material is good, the TPU can be uniformly dispersed in the PVC, the wear resistance and the low temperature resistance of the clad layer of the conveyor belt can be improved, the mechanical property of the material can be improved, the wear-resistant and low-temperature-resistant performance is superior to that of a traditional PVC coating clad layer, and the lightweight conveyor belt can be used for a long term in a low-temperature environment at the temperature of 30 DEG C, and the technical problems that the lightweight conveyor belt is prone to brittle cracking, easy to wear and the like in a low-temperature environment can be effectively solved.
Description
technical field [0001] The invention relates to a wear-resistant and cold-resistant modified polyvinyl chloride (PVC) / thermoplastic polyurethane elastomer (TPU) composite light-duty conveyor belt and a preparation method thereof. Background technique [0002] Lightweight PVC conveyor belt is composed of single-layer or multi-layer reinforcement and covering rubber layer. It has the characteristics of light weight, good dimensional stability, high tension, bright color, safety and non-toxicity, etc. It is widely used in various industries, among which polyester The light PVC conveyor belt with fabric as the matrix and PVC resin as the matrix is often used in the production lines of various industries. However, during the use of light PVC conveyor belt, the wear resistance and low temperature resistance are poor, especially in the north, the surface of the conveyor belt will be brittle and worn, resulting in the reduction of the mechanical properties of the conveyor belt and...
