A kind of preparation method of porous oil-containing lubricating material

Abstract

The invention discloses a method for preparing a porous oil-containing lubricating material and belongs to the technical field of lubricating material preparation. In the invention, prepared black fungus powder is mixed with chitinase solution through stirring, enzyme deactivation and centrifugal separation treatment are performed to obtain supernatant, the supernatant is mixed with absolute ethyl alcohol, then centrifugal separation and sediment collection are performed to obtain black fungus polysaccharides, then the black fungus polysaccharides, deionized water and trisodium citrate are subjected to heating and ultrasonic dispersion treatment to obtain black fungus polysaccharide dispersion liquid, then lubricating mixture liquid prepared by mixing lubricating oil with the black fungus polysaccharide dispersion liquid is mixed with styrene monomers and acrylate, heating and filtration are performed, a filter cake is collected, washed and dried to obtain modified oil-containing resin particles, the modified oil-containing resin particles are mixed with talcum powder and azodicarbonamide, then kneading is performed, and then discharging and cooling are performed to obtain a porous oil-containing lubricating material. The lubricating material prepared by adopting the method disclosed by the invention has the advantages of high porosity, uniform distribution, high material strength, good binding force with substrates and greater application space.

Description

technical field [0001] The invention discloses a preparation method of a porous oil-containing lubricating material, belonging to the technical field of lubricating material preparation. Background technique [0002] With the continuous development of society, people's requirements for the quality of social products are getting higher and higher, which also puts forward higher standards for the production of industry and daily necessities. As a result, the industrial revolution was set off, and the industrial revolution also led to the technological upgrading of equipment. [0003] When two objects in close contact move relative to each other along their contact surfaces, there will be a kind of resistance, which is friction force, and this phenomenon is friction. Two friction surfaces that are in contact with each other are called friction pairs. Any mechanical movement is realized by the relative motion of various friction pairs, so friction is inevitable. Friction cause...

Problems solved by technology

[0006] The technical problem mainly solved by the present invention is that existing porous oil-containing lubricating materials have uneven pore distribution, low porosity, low self-strength, poor bonding force with the matrix, and the pores are easily affected by the environment and precipitated when the lubricating oil material is adsorbed. The problem leading to the failure of lubricating materials provides a preparation method of porous oil-containing lubricating materials. In this method, the prepared black fungus powder and chitinase solution are stirred and mixed, and the supernatant is obtained after deactivation and centrifugation. After stirring and mixing with absolute ethanol, centrifuge to collect the lower precipitate to obtain black fungus polysaccharide, then heat it with deionized water and trisodium citrate in a water bath, and ultrasonically disperse to make a black fungus polysaccharide dispersion, then mix lubricating oil with black The lubricating mixture prepared by mixing the fungus polysaccharide dispersion is mixed with styrene monomer and acrylate, heated and filtered, and the obtained filter cake is washed and dried to make modified oleoresin particles, which are mixed with talcum powder and azodicarbonamide Mixing and banburying, followed by discharge and cooling, a porous oil-containing lubricating material can be prepared. The preparation process of the present invention is simple, and the prepared lubricating material has a rich porous structure, and the pores are evenly distributed, and the strength is high, and it is compatible with the matrix. High binding force, not affected by the environment, can continuously and stably supply oil to the friction pair, and has a large application space
