Embodiment 1
[0018] Embodiment 1 A wear-resistant bearing material, its preparation method comprises the following steps:
[0019] (1) Add 100g nickel nitrate hexahydrate, 80g ruthenium trichloride, and 120g urea into 1Kg water, add 35g mica powder after stirring for 30 minutes; add 20g sodium percarbonate after stirring again for 15 minutes, finish adding in 15 minutes, the third time After stirring for 50 minutes, the filler mixture was obtained; then the mixture was poured into a flat plate and then heat-treated in a vacuum at 120°C, and the vacuum environment was a conventional vacuum oven to obtain a powder; then the powder was calcined at 550°C for 1.5 hours to obtain a block; finally, the block was crushed Obtain micron fillers with a particle size of 200-350 microns;
[0020] (2) Add 100g of allylboronic acid to 1000g of cyanate, heat and stir at 95°C for 30 minutes, then add 80g of diethylphenylphosphate and 100g of tetraethoxysilane, stir again at 115°C for 90 minutes, then add 8...

Abstract
The invention provides a wear-resistant bearing material. The wear-resistant bearing material is obtained by adding a resin system into an organic solvent, agitating, then adding a micron filling material and polycaprolactone diol, agitating again to obtain wear-resistant slurry, coating the wear-resistant slurry on a steel plate with copper powder, and carrying out heat treatment. According to the wear-resistant bearing material, through technological selection, the probability that raw materials are in contact with one another is higher in a reaction process; a reaction is prevented from being excessive to cause that a thermal reaction is not uniform in a mixing process; a reaction speed is quicker on a thermal occasion; the generation rate of a cross-linked network is higher; through regulating temperatures and time of agitation and the thermal reaction, the extent of the reaction is controlled during mixing; a method is ingenious and further reasonable in design; through adding additives including an inorganic material and a metal compound and the like, the wear-resistant strength of a resin matrix composite material is increased.
Description
technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a wear-resistant bearing material. Background technique [0002] Composite materials are widely used in metallurgy, non-ferrous metals, machinery, petrochemical, electric power and other fields. The composite material has the characteristics of low density, high flexibility, waterproof, etc., can collect excess heat, has good randomness, has no cavity, and can avoid tearing and falling off under negative wind pressure. Self-lubricating bearings have begun to receive attention because they are suitable for places where lubrication is unreliable or impossible. Single-material self-lubricating bearings generally have two structures: copper powder metallurgy and plastic. The structural strength of copper powder metallurgy is relatively low, it is difficult to be suitable for high-load working conditions, and it is easy to cause strain during the running-in p...
