Analysis of Basic Properties of Rubber Conveyor Belt

Conveyor belt is generally composed of three parts: skeleton material, covering layer and bottoming material. According to the material of the covering layer, conveyor belts can generally be divided into rubber conveyor belts and light conveyor belts. The covering layer of the former is mainly made of various modified natural rubber, synthetic rubber and special rubber, and the latter is made of various high Molecularly modified materials mainly include modified PVC, PE, TPU, TPEE, silica gel materials, etc.

Rubber conveyor belts are mainly used in the transportation of heavy materials in heavy industry, and play the role of carrying and transporting materials. In the process of use, it can reduce labor intensity by 60%, reduce labor by 40%, and increase work efficiency by 3.5 times; if combined with palletizers and other machinery, it can reduce labor intensity by 75%, reduce labor by 40%, and improve work efficiency 8 times. The rubber conveyor belt can be transported continuously, with high efficiency and large inclination. It has the advantages of safe operation, simple use, easy maintenance, and low freight. It can shorten the transportation distance, reduce the project cost, and save manpower and material resources.

There are many types of rubber conveyor belts, classified according to their functional characteristics: general purpose conveyor belts, flame retardant and antistatic conveyor belts, general flame retardant conveyor belts, heat and high temperature resistant conveyor belts, acid and alkali resistant conveyor belts, oil resistant conveyor belts, cold resistant conveyor belts Conveyor belt etc.

The raw materials of rubber conveyor belts are mainly raw rubber, additives and framework materials. The raw rubber used in the rubber conveyor belt process mainly includes natural rubber, styrene butadiene rubber, and butadiene rubber, and the proportion of materials used reaches 40%. Carbon black, zinc oxide, accelerators, antioxidants and other rubber additives account for 30% and 10% of the manufacturing process, respectively. Each manufacturer will adjust the ratio of raw materials to different extents according to cost. The development of conveyor belts is inseparable from the improvement of the performance of the framework material. The strength, extension characteristics, elasticity, toughness, and dimensional stability of the conveyor belt are closely related to the framework material. The skeleton materials of the rubber conveyor belt include fiber skeleton and metal skeleton, among which the fiber skeleton materials are mainly cotton, polyester, nylon and aramid. The downstream application of rubber conveyor belts is mainly the coal industry, which accounts for about 50%, followed by the steel industry, which accounts for about 20%. Other application areas include cement, thermal power generation and port transportation.
