Self-repair solution, preparation method and use method thereof

Abstract

The present invention provides a self-repair solution, a preparation method and a use method thereof. The self-repair solution comprises, by mass, 2-30% of nanometer attapulgite powder, 1-30% of nanometer copper alloy, 0.5-5% of nanometer lanthanum oxide, 0.5-5% of oleic acid, 1-10% of a dispersant, and 50-95% of base oil, wherein the dispersant is one selected from dialkenyl succinimide, mono succinimide, and poly succinimide, the base oil is synthetic ester base oil or mineral base oil, and the nanometer attapulgite powder adopts natural attapulgite as a raw material, is subjected to industrial purification, and has a purity of more than or equal to 75%. The self-repair solutions of the present invention has high anti-wear shocking reducing property so as to substantially reduce the surface roughness of parts and reduce friction, such that the purposes of energy saving, consumption reducing, and equipment service life prolonging can be achieved.

Description

technical field [0001] The invention relates to a self-repairing solution, in particular to a self-repairing solution applied to metal parts under oil-lubricated conditions to reduce frictional surface wear of the metal part, its preparation and use. Background technique [0002] With the development of modern industry, the design and operating conditions of mechanical equipment are becoming more and more stringent, and the performance requirements are getting higher and higher. There are a lot of technical problems such as friction and wear failure in the use of these equipments, and wear failure has become one of the technical bottlenecks restricting the safety, reliability and service life of equipment. [0003] Wear generally starts with early mild surface micro-damages and then develops into severe surface damages. Therefore, avoiding the slight wear of the early wear surface or preventing mild micro damage from turning into severe surface damage is one of the importan...

AI Technical Summary

Problems solved by technology

[0007] At present, the above-mentioned nano-self-repairing materials are mainly prepared by chemical synthesis or ultrafine pulverization. The advantages of using the nano-self-repairing materials prepared according to the existing technology are that the particle size is controllable and the surface activity is high, but it is made into an additive and added to a lubricating medium. (such as lubricating oil) has the following disadvantages: on the one hand, the dispersion stability of micro-nano materials in the lubricating medium is poor, which leads to the agglomeration and precipitation of micro-nano materials, thus losing the function of anti-friction and self-repairing, and even causing Severe abrasive wear; on the other hand, the preparation process of micro-nano self-healing materials is complicated and expensive, which makes the self-healing solution prepared by using the micro-nano self-healing materials expensive and difficult to promote and apply on a large scale
