Description

Water-base conductive lubricating oil and working method

Technical field:

The present invention relates to a kind of lubricating oil, especially a kind of lubricated and conduct electricity very well, cost is low, satisfy the water-base conductive lubricating oil and the working method of environmental requirement.

Background technology:

Element in the mechanical means provides necessary power through equipment, carries out relatively sliding or rotation, will produce friction between two mechanical organs that contact with each other.The frictional force that produces in order to reduce; Reduce wear; The heat of friction that stops the antithesis relative movement to produce; Prevent the mechanical organ surface corrosion, prolong the work-ing life of antithesis mechanical organ, the mechanical organ in the assurance equipment runs well for a long time, just must be to the mechanical organ execution swabbing of two antithesis of relative movement.Swabbing generally is divided into hydrodynamic lubrication, mixed lubrication and boundary lubrication, in industrial production, the lubricated widespread use of mechanical means be exactly hydrodynamic lubrication.The mechanism of action of hydrodynamic lubrication is to form one deck on the mechanical organ of relative movement surface continuously and have the fluid lubricant film of enough pressure and friction surface is separated; The lubricated employed lubricating oil of general fluid should have good lubricating effect; Has cooling effect preferably again; Therefore, existing lubricating oil all is oil base lubricating oil mostly, and the lubricity of the water-base lubricant of few part is relatively poor.But; Some specific equipment is when the aluminium zinc of processing particular requirement, admiro, aluminum magnesium alloy, cupronickel workpiece, and lubricant not only only is lubricated the workpiece face, when in equipment, circulating; Lubricant also directly acts on the whole work-piece surface; The lubricant that is adopted just must be an aq. type, can play lubricated effect, can play electrolytical effect again.But, existing water-base conductive lubricating oil adds needed lubricated and conductivity in man-hour because can not satisfying the lubricated and specific alloy workpiece of specific equipment mechanical organ; Directly influence the normal operation of these specific equipments, bring very big difficulty for the processing of specific alloy workpiece.

Summary of the invention:

The present invention is in order to solve the above-mentioned technical problem of existing in prior technology, provide a kind of lubricated and conduct electricity very well, cost is low, satisfy the water-base conductive lubricating oil and the working method of environmental requirement.

Technical solution of the present invention is: a kind of water-base conductive lubricating oil, it is characterized in that raw materials used and weight percent following:

Polyoxyethylene glycol 13～15%

USP Kosher 11～13%

Trolamine 5～7%

Alizarin assistant 4～6%

Saltpetre 0.5～1.5%

RH-893 0.05～0.15%

Deionized water 61～63%.

Preferred plan raw materials used and weight percent is following:

Polyoxyethylene glycol 14%

USP Kosher 12%

Trolamine 6%

Alizarin assistant 5%

Saltpetre 1%

RH-893 0.1%

Deionized water 62%

A kind of working method of water-base conductive lubricating oil is characterized in that carrying out as follows:

A. elder generation joins the deionized water of calculated amount in the reaction kettle, and the saltpetre with calculated amount adds wherein again, agitator, and rotating speed is 200 rev/mins of stirring at normal temperature 30 minutes;

B. add polyoxyethylene glycol, USP Kosher, trolamine, alizarin assistant and RH-893 more successively, and be warmed to 50～60 ℃, continuously stirring 2 hours;

C. reduce to normal temperature.

The present invention is a water-base conductive lubricating oil, on the metallic surface, sticks easily and launches, and has excellent lubricating properties; The polar group of the surfactant that is contained has very big avidity to the antithesis mechanical organ metallic surface of relative movement; The polar group of polar molecule has stronger chemisorption and physisorption simultaneously; Can easily be adsorbed on the metallic surface; With higher, stable, the firm more lubricant film of formation fusing point, also unlikely destruction under the rubbing effect of high pressure, high temperature and fierceness, it is lubricated and cooling performance is better; Conducting material that the present invention is used and lubricated promoting agent coupling are dissolved each other, and function is not separately offset mutually, and its electric conductivity is stabilized in the technical indicator scope; The present invention is not perishable in long storage or use, especially uses its long quality-guarantee period in summer, and is nontoxic to operator, environmentally safe.
