Wear-resistant material with thermal response and self-lubricating properties and preparation method thereof

Abstract

The invention relates to a wear-resistant material with thermal response and self-lubricating properties and a preparation method thereof. The method of the invention comprises the following steps: 1. Dissolving both the high polymer and the nano-type fluid prepared by the ion exchange method in an organic mixed solvent , stir evenly to obtain a mixed solution, the mass concentration of the nano fluid in the mixed solution is 10%-30%, and the mass concentration of the high polymer is 10%-30%; 2. The mixed solution is injected into the mold, and air-dried at room temperature to obtain Wear-resistant material with thermally responsive and self-lubricating properties. The invention utilizes the special structure of the inorganic-organic combination of nano-type fluids, so that the inorganic particles in the lubricating film can isolate the direct contact of the friction pair and reduce the loss of the friction pair, and also fill the self-repairing function of the surface scratches, so that the resistance of the invention can be improved. The abrasive material has thermal response and self-lubricating properties, that is, it can secrete lubricating substances by itself during use, no additional lubricating fluid is required, and it is easy to use and has good wear resistance.

[0002] With the development of industry and the increase of people's demand, the improvement of output puts forward more efficient requirements for the production and processing of machines. Friction, as a common physical phenomenon, widely exists in industrial production. The existence of friction leads to the interaction between objects The transfer of substances on the surface causes the loss of mechanical contact surfaces, accelerates the aging of machinery, causes unnecessary consumption of manpower and material resources, increases production costs, and brings adverse effects on industrial production. In order to solve this problem and respond to the call for environmental protection, It is imperative to improve mechanical wear resistance, prolong service life and reduce energy consumption

The improvement of the original mechanical lubricity and wear resistance is mainly achieved by adding lubricant between the friction surfaces to achieve the lubrication effect. Due to the loss of lubricating oil caused by the operation and extrusion of the machine, it is necessary to continuously add lubrication to the friction center layer, mechanical self-lubrication cannot be achieved, and work efficiency is low
