Description
Technical field
The present invention relates to a kind of novel nano metal self-restoring lubricating oil that is applicable to multiple friction pair in the mechanical sealing member, suitable friction pair comprises graphite/steel, steel/steel, Wimet/Wimet, SiC/SiC, tetrafluoroethylene/Al
2O
3, graphite/SiC.
Background technology
It is reported that 30～50% of the produced worldwide energy is lost in the frictional wear, China annual because of frictional wear cause with a toll of more than one hundred billion Renminbi.Therefore, reduce friction, reduce wearing and tearing, improve plant factor, increase the service life, be one of important content of countries in the world research always.In mechanical sealing member, the oil product of used seal lubrication is very big to product work-ing life and energy consumption influence.The friction of sealing section can consume mechanical power, reduces mechanical efficiency; The generation of wearing and tearing then can make friction pair parts forfeiture dimensional precision, causes seal failure, thereby leaks, and causes equipment scrapping.For reducing wearing and tearing, except that carrying out rational tribology Design, also can solve by good lubrication that improves the special lubricating oil realization of employing friction pair and wear-resistant, the antifriction performance that improves friction pair material.Because article one approach is subjected to many restrictions of the aspects such as cost, processing and working conditions of part in actual mechanical process, therefore, more use occasion still realizes antifriction between the friction pair and wear-resistant by developing lubricating oil efficiently.
In research and practical application, find, adopt lubricating oil merely, be difficult to satisfy the requirement of various different application occasions, particularly do not possess the requirement of wear surface being carried out selfreparing.It is to add the various organic and inorganic compound with difference in functionality lubricating oil is carried out modification in lubricating oil that the tradition of these lubricating oil is improved one's methods, to improve the physicochemical property of lubricant medium, improve the supporting capacity of lubricating oil (fat) film and reduce frictional coefficient.But also brought the part side effect simultaneously, in friction process, may produce objectionable constituent as part of compounds, particularly warm when higher when oil, may play corrosive nature to the bearing materials of non-ferrous metal, the easy decomposition and consumption of some oil soluble organic additive needs constantly to replenish.In addition, the synthesis technique complexity of this additive, some has chemical pollution, makes its development be subjected to certain limitation.But the analysis that has the acidic substance that produce after better suspension characteristic and neutral lubrication oil oxidation and the fuel combustion based on nanoparticle, the research of nanometer lubricating additive has in recent years caused the generally attention of countries in the world, and has developed multiple nano level slip additive.The JB automobile patron saint series that contains polymkeric substance as the production of U.S. Justicebrothers company; The anti-serial anti-wear agent of speeding of the peace that contains the unit molecule carbon compound that U.S. ER company produces; The Slick50 engine antifriction lubricant that contains the PTFE material that U.S. Petrolon produces.
The nano antiwear agent product of development emerges in large numbers gradually both at home and abroad, mostly the target market is locked on the vehicles.Yet industrial goods has more wide user group, and mechanical sealing member is the common running stores of industries such as chemical industry, agricultural, metallurgy, and too much damage causes maintain and replace frequent, has had a strong impact on the service efficiency of equipment.In addition, for the improvement of industrial goods, emphasis to consider cost, the cost raising too much is not suitable for promoting in the industry.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of nano metal self-restoring lubricating oil for mechanical sealing element and preparation method thereof, this preparation method is simple, the cost increase less, pollution-free, the formed reconditioning layer hardness of this self-restoring lubricating oil agent height, frictional coefficient is little, rerum natura is stable.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of nano metal self-restoring lubricating oil for mechanical sealing element, be made up of Nano metal powder, nano metal powder dispersion agent and dispersion medium, the weight percentage of the shared nano metal self-restoring lubricating oil total amount of each component is as follows:
Nano metal powder 0.07～0.15%
Nano metal powder dispersion agent 0.2～1%
Dispersion medium 98.9～99.7%.
Nano metal powder is a kind of in copper nanoparticle, nanometer copper nickel composite powder and the nanometer copper bismuth composite powder, the mean particle size≤80nm of nickel, bismuth wherein, and the mean particle size≤60nm of copper, wherein the proportioning of copper nickel is 8: 2, the proportioning of copper bismuth is 8: 2.
The nano metal powder dispersion agent is at least a kind of in Sodium hexametaphosphate 99, oleic acid, hard ester acid and the silane coupling agent.
Dispersion medium is a machine oil.
The preparation method of nano metal self-restoring lubricating oil for mechanical sealing element the steps include:
1.. stir in earlier that proportioning is the required nano metal powder dispersion agent adding dispersion medium, further add Nano metal powder more according to the above ratio, agitation as appropriate to nano metal powder does not have obvious sediment;
2.. put in the KH-700 type ultrasonic oscillator together with container and to vibrate 20～30 minutes, power is 500～600W, product, can use in a conventional manner in mechanical sealing member, perhaps can to the container as sell goods.
The invention has the beneficial effects as follows: laboratory and the actual equipment test result that uses show, add the suitable Nano metal powder and the machine oil of dispersion agent, than the machine oil that does not add additive, mechanical sealing member normally uses in half an hour, the frictional coefficient of sealing section is reduced to 0.036 by 0.046, has reduced by 21.7%.And by adjusting component ratio applicable to multiple friction pair, can improve the friction pair gap, after this reconditioning layer forms, do not come off through behind the long-play, can in time repair the wearing and tearing that produce in the friction, effectively prolong stopping the cycle of repairing of use equipment, reduce that equipment running cost and preparation method are simple, the cost increase less, pollution-free etc.
