Problems solved by technology

However, rubber has low elastic modulus, poor bearing capacity, and there are phenomena such as aging and crawling.
Polyurethane tends to generate a lot of heat during the friction process, and its friction coefficient is large, and its anti-interference ability is poor, so it is difficult to exert its excellent performance

Abstract

The invention relates to the technical field of composite materials, and relates to a composite water-lubricated bearing material and a preparation method thereof. The composite water-lubricated bearing material comprises the following raw materials in parts by weight: 100 parts of polyurethane pre-polymer, 10-20 parts of sodium polyethylene oxide, 1.5-1.8 parts of polyoxyethylene polyoxypropanolamine ether, 20-30 parts of 4,4'-methylene bis(3-chloro-2,6-diethylaniline), 2.5-3 parts of polytetrafluoroethylene, 3-4 parts of glass fiber, 8-10 parts of boron carbide, and 8-10 parts of lead powder. The obtained composite water-lubricated bearing material has the advantages of excellent friction resistance and good impact resistance through synergistic actions of the components. The preparationmethod of the composite water-lubricated bearing material has simple process and is suitable for industrialized production.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a composite water-lubricated bearing material and a preparation method thereof. Background technique [0002] Water-lubricated bearings use water as the lubricating and working medium, which can reduce the environmental pollution of traditional bearings that use oil as the lubricating medium, and save a lot of oil. In addition, water has the advantages of no pollution, wide range of sources, safety and flame retardancy. If water is used instead of oil as the lubricating medium, it will bring an unprecedented revolution to the traditional mechanical transmission system, and the structure and materials of water-lubricated bearings will therefore It has become the object of attention of mechanical design and material researchers from all over the world. [0003] Water-lubricated bearings are composed of a bearing jacket and a bearing surface layer. The bearing jacket is...
