Abstract
This invention relates to the chemical domain, publicizes one kind wearresistant repair agent preparation method and its application, its characteristic lies in the wearresistant repair agent including the phyllo-silicate mineral smalls which ferric oxide content is smaller than 2%, six sides boron nitride, the dispersing agent, base oil, among them, the ferric oxide content of phyllo-silicate mineral smalls is smaller than 1%, its granularity request is D97 ( 1 micron; Six sides boron nitride granularity request is D97 (1 micron; This invention has also publicized the preparation method and application of the wearresistant repair agent. The wearresistant repair agent have good dispersible stability, and it can willfully mix with the lubricating oil, it enable the lubricating oil to have the function of compensating the attrition. After using the wearresistant repair agent, it can obtain the lubricating ability carbon oxide film in the friction surface, this carbon oxide film has high hardness, high degree of finish, low friction coefficient, low rate of wear, self-compensated, self-healed, self-repair ability, it provides the exempt dismantling repair possibility of equipment maintenance.
Description
Technical field:
The present invention relates to chemical field, particularly nanotechnology and machinery exempt to tear open maintenance and lubricating grease technical field, particularly a kind of agent for repairing abrasion resistance and its production and application.
Background technology:
In mechanical means, the existence of friction has consumed portion of energy, has reduced the efficient of equipment; The generation of wearing and tearing can make component reduce dimensional precision gradually and lose efficacy, even causes equipment scrapping.For reducing or the inhibition frictional wear, except that carrying out rational tribology Design, also must take the measure of various anti-attrition anti-friction, the mode of employing has following several: the one, and minimizing or control cause the condition of wearing and tearing, as corrosion and fatigue, adhesion, erosion, abrasive wear etc.; The 2nd, the wear resisting property of raising surface of friction, as surface alloying, sulfurizing, boronising etc., or make material have self-organization, self-healing ability; The 3rd, in process of friction and wear, remedy wearing and tearing by forming new layer of compensation.And above three kinds of measures can be by to lubricating oil product Formula Design and utilize fricative physics chemical action to realize.
Because the influence of factors vary such as the temperature that produces when the physico-chemical property of lubricating oil, lubricating grease is subjected to the surface of friction motion or during environmental change, pressure is difficult to effectively lubricating and control wearing and tearing.For remedying the defective of lubricating oil, lubricating grease, method commonly used at present is to wherein adding various organic and inorganic compound additives, and these materials roughly can be classified as following a few class:
1. organometallic compound is as zinc dialkyl dithiophosphate etc.;
2. the organic compound of sulfur-bearing, phosphorus, chlorine isoreactivity element is as sulfide isobutene etc.;
3. the solid lubricant that has special constructions such as stratiform is as molybdenumdisulphide etc.;
4. micron, nano level soft metal are as copper etc.
Above-mentioned 1. 2. the class material mostly be oil-soluble compounds, under boundary lubrication and mixed lubrication condition, by modes such as thermolysiss, form adsorption film, reaction film or permeable membrane, thereby improve the lubricating status of surface of friction on the surface of metal mill spot.But when friction Temperature Rise was higher, adsorption film can decompose, or some degradation production of these compounds can have corrosive nature to metallic substance, and the decomposition and consumption when high temperature reduces its performance simultaneously.3. the class material can be easy to take place crystal-plane slip frying in shallow oil under the shear force effect, thereby reduces wearing and tearing, but its lubricity deficiency at a lower temperature.More than three class materials all can not repair occurring wear.Though 4. the class material can infiltrate the metallic surface in friction process, or be filled in the depression of friction surface, can improve the loaded area of surface of friction, ability with certain reparation wearing and tearing, but the new reparation surface that forms does not often have original surface more wear-resisting, reduce in oiling system with material, its repairing effect is with very fast disappearance.
In addition, up-to-date method is to utilize wear-resistant, the anti-attrition of oxide compound.Because a large amount of mechanical means is operated in the atmospheric environment, no matter be in lubricated, metal to-metal contact, particularly under hot conditions, its friction surface will inevitably oxidation, and oxide compound will participate in process of friction and wear.Oxidative wear will become the leading mechanism of wearing and tearing under certain condition.And friction oxidation has the different of essence with thermooxidizing, this be since under the andfrictional conditions solid mechanical interaction cause due to the structural changes and physical change of solid surface, friction makes metal produce various defectives, temperature rising, plastoelastic deformation, surface enlarge, bring out electronics etc., thereby rate of oxidation is accelerated, and can be produced the resultant different with thermal oxidative reaction.Along with deepening continuously of oxide compound anti-attrition and wear-resisting phenomenon research, the structure of the spontaneous oxide film that discovery forms under common lubricating condition is also stable inadequately, and oxide film breakdown can take place; Thickness deficiency, effectively bearing load; Compactness deficiency, hardness are not high, can not effectively reduce adhesive wear; Formation speed is low, can not provide effective anti-attrition during less than wear rate.Therefore utilize the oxide compound anti-attrition never to be widely used.
Summary of the invention:
The objective of the invention is to overcome that existing oxide compound is wear-resistant, the deficiency of anti-attrition technology, a kind of agent for repairing abrasion resistance of obtaining at friction surface oilness oxidation of coal film and its production and application that is used for is provided.
One of prerequisite of utilizing the oxide compound anti-attrition is: the formation speed of oxide film must be greater than the removal speed of its mechanical wear, so must find a kind of particularly can the film formed material of promote the oxidation under the situation that has lubricant medium to exist, be the key that addresses this problem.
By a large amount of tests, we find that layered silicate material has katalysis to the formation of oxidation of coal film, it can discharge oxygen freely in friction process, and carbon and other light elements (nitrogen, boron) that can quicken the lubricating oil decomposition ooze to the metal friction surface expansion, and then form oilness oxidation of coal film.
