Description

technical field [0001] The invention belongs to the technical field of polymer processing, and in particular relates to a graphene-modified high-density polyethylene composite material for idlers and a preparation method thereof. Background technique [0002] Belt conveyors, also known as belt conveyors, are widely used in household appliances, electronics, coal mines, building materials and other fields. The idler roller is one of the important parts of the belt conveyor. It is composed of the idler tube body, the bearing seat and the inner and outer seals. impact and prevent the conveyor belt from running off. The cost of the idler can account for about a quarter of the total price of the conveyor, and its maintenance and replacement costs are also an important part of the cost of the belt conveyor. Therefore, the performance and quality of the idler will directly affect the cost and service life of the conveyor. [0003] In the current market, rollers can be divided int...
