The invention belongs to the manufacture of polymer wear-resistant materials and relates to the manufacture of a material for the parts of a railway freight car, particularly to a material used for the slide groove wear plate of the railway freight car. The material is the blend of various nylon materials in weight proportions as follows: 20-25 parts of nylon 6, 70-80 parts of nylon 66, 15-20 parts of nylon 12 and 30-40 parts of nylon 1010. The slide groove wear plate made of the material can meet the requirements of strength, rigidity and frictional property for railway freight cars. Compared with the prior metal wear plate, the slide groove wear plate has improved wear resistance, prolonged service life, good elasticity, and less difficulty in embedded installation.
Description
technical field [0001] The invention belongs to the manufacture of polymer wear-resistant materials, and relates to the manufacture of a railway wagon component material, in particular to a railway wagon chute wear plate material. Background technique [0002] The wear plate of the traditional railway freight car chute is generally made of metal, and the friction between it and the body of the freight car chute is metal-to-metal. The product wears quickly during use, has a short service life and a large maintenance workload; in addition, the metal material When performing embedded security, it is not easy to install and difficult to operate. [0003] The technical problem to be solved by the present invention is to provide a railway wagon chute wear plate with low wear rate, strength and rigidity that can meet the use requirements of the wagon chute wear plate. Contents of the invention [0004] The material of the railway freight car chute wear plate of the present inven...
