Problems solved by technology

The structural strength of copper powder metallurgy is relatively low, it is difficult to adapt to high-load working conditions, and it is easy to cause strain during the running-in period
Existing bearing materials need to add molybdenum disulfide as wear-resistant phase, otherwise they cannot be used

Embodiment 1

[0017] Embodiment 1 A preparation method of slurry for wear-resistant bearings, comprising the following steps:

[0018] (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;

[0019] (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 ad...

Abstract

The invention provides a method for preparing slurry for a wear-resistant bearing. The method comprises the following steps: adding a resin system into an organic solvent, stirring, and adding micrometer packing and polycaprolactone dihydric alcohol; and stirring for a second time to obtain the slurry for the wear-resistant bearing. Through process selection, the probability that raw materials contact mutually in the reaction process is higher, non-uniform thermal reactions caused by excessive reactions in the mixing process are avoided, the heat reaction speed is higher, and the cross-linkingnetwork generation rate is higher; by adjusting stirring and heat reaction temperatures and time, extent of reaction in mixing can be controlled, and the method is smart and reasonable in design; with the addition of additives such as an inorganic material, metal compounds and the like, the wear resistant strength of a resin substrate composite material is increased.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of slurry for wear-resistant bearings. 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 strai...
