Abstract

The invention belongs to the technical field of composite materials and discloses a low-friction water lubricating macromolecular bearing composite material which is characterized by comprising ultra-high molecular weight polyethylene, polystyrene-ethylene-butylene triblock copolymer, polyvinyl alcohol, graphite and molybdenum disulfide, wherein each 100 parts of ultra-high molecular weight polyethylene is blended with 10-40 parts of polystyrene-ethylene-butylene triblock copolymer, 2-5 parts of polyvinyl alcohol, 2-10 parts of graphite and 1-5 parts of molybdenum disulfide. The low-friction water lubricating macromolecular bearing composite material provided by the invention is formed by adopting an effective material blending scheme.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a low-friction water-lubricated polymer bearing composite material. Background technique [0002] Compared with traditional oil-lubricated bearings, water-lubricated bearings use water as a lubricant. They have the advantages of environmental friendliness, simple structure, low friction coefficient, and high safety performance. They are widely used in ships, ships, marine engineering, water pumps, turbines and other fields. [0003] Iron pear wood was first used in water-lubricated bearings. With the depletion of resources, rubber, fiber-reinforced phenolic resin, nylon, polytetrafluoroethylene, ultra-high molecular weight polyethylene, polyethersulfone, polyether ether ketone, polyimide, etc. Synthetic polymer alternative materials. Among all polymer materials, the special elastic behavior of rubber materials ensures its excellent vibration damping performance and s...
