Abstract

The invention discloses a composite material for a water lubricated bearing, and belongs to the technical field of a polymer composite material. The technical scheme of the invention is that: the composite material comprises the following raw materials in parts by weight: 100 parts of rubber, 2 to 12 parts of active agent, 0.5 to 2 parts of anti-aging agent, 20 to 70 parts of carbon black, 0.5 to2 parts of vulcanizing agent, 0.5 to 1.5 parts of accelerant and 1 to 50 parts of basalt fibers; and the raw materials above are used for preparing according to a special preparation method. The composite material has the beneficial effects that the composite material disclosed by the invention has the advantages of wide applicable temperature, excellent wear resistance, low wear rate and long service life under the water lubricated condition; the composite material uses nitrile rubber, carboxy nitrile rubber and hydrogenated nitrile rubber which are excellent in heat resistance and excellentin wear resistance as base materials; and by adding the basalt fibers and using the special preparation method, wear resistance of the rubber, particularly wear resistance in a water environment at ahigh temperature, is promoted.

Description

technical field

[0001] The invention belongs to the technical field of polymer composite materials, and in particular relates to a composite material for water-lubricated bearings. Background technique

[0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings can be divided into sliding bearings and rolling bearings, where sliding bearings refer to bearings that work under sliding friction. Under liquid lubrication conditions, the sliding surfaces are separated by the lubricant without direct contact, which can greatly reduce wear. Water-lubricated bearings use water as a lubricant. Compared with traditional oil-lubricated bearings, they have the advantages of environmental protection and low energy consumption. They are widely used in water turbines, marine pumps, sewage pumps, petrochemical and o...
