A machine tool lubricating oil or hydraulic or tapping fluid composition comprises in a mineral oil or other lubricant base and an oil-water partitionable anti-microbial, active against micro-organisms present in oil-water metalworking fluids.
Description
Technical field
The present invention relates to the prevention that microorganism grows in a kind of metal working fluid of machine, lubricating oil or hydraulic fluid in this machine (hydraulic fluid) or perforated liq (tapping fluids) may the pollution metal working fluids, the invention still further relates to machine tool lubrication agent, hydraulic fluid or the perforated liq etc. that comprise antiseptic-germicide, more particularly, the present invention relates to antiseptic-germicide is joined method in the metal working fluid.
Background technology
In a lot of mechanical environments, exist oiliness compound and aqueous compounds simultaneously.A lot of machines adopt in closed environment and comprise a kind of high-pressure and hydraulic oil, i.e. a kind of hydrodynamic drive of oil.Yet, the aging and leakage of hydraulic fluid of sealing-ring may take place, thus the pollution metal working fluid.
A kind of lubricating compound of the common needs of mechanical process prevents the friction between the moving parts.An example of this system is the lathe of Industrial Metal processing, and wherein workpiece and instrument are placed on the level and smooth bearing that is commonly referred to as chute, and moves thereon.These surfaces need a kind of lubricant-slideway-reduce the metal/metal contact, thereby eliminate friction and ' viscous ' (stick-slip) slides, and prevent that chute from wearing and tearing.This is in shape and guarantee that mechanical workout accurately is necessary for keeping those very expensive lathes.Because most of mechanical processing process also adopt a kind of liquid that adds, promptly water-fat liquor metalloid working fluid makes processing district cooling and lubricated, so slideway is constantly washed off from the slideway surface.In order to prevent this problem, on the basis of continuous or metering, most lathe distributes oil on the trend slideway.If the slideway cost is very low, the method for this complete loss is the cheapest method of cost of guaranteeing that machine performance is without prejudice.The lubricant of loss is the oil (tramp oil) that loses in the course of processing, is washed in the storage tank with metal working fluid, and metal working fluid can recycling from storage tank.
Though this method guarantees that machine is in good state, it brings opposite effect to metal working fluid.Metal working fluid is an oil-in-water emulsions, for growing of microorganism provides ideal environment.Though when the preparing metal working fluid, remove tangible nutrition source very hand and foot, and guarantee the antimicrobial as much as possible growth of metal working fluid,, just can not stop growing of microorganism to a great extent if metal working fluid has been polluted by slideway.Because slideway is generally based on purified mineral oil, contain for example element of sulphur and phosphorus (as anti-wear agent and sanitas), these provide the ideal nutrition for microorganism.At whole metal-processing industry can received one of the main reasons for the metal working fluid failure be that metal working fluid has been promoted growing of microorganism by excessive contamination with slideway lubricants.In system, by means of stirring at low speed, chute lubricating oil can be separated from emulsion, and is again that emulsion is airtight isolated with air.Under this anaerobic condition, microorganism growing in liquid produces the respiration by product, hydrogen sulfide for example, and hydrogen sulfide brings a kind of uncomfortable smell that makes us, and makes us uncomfortable when making this system works.
The perforated liq that applies can be used for perforate, fraising and drilling operation by hand, and when being used from the lathe with water mixture one, the current that added cutting fluid also can pollute cutting fluid.
Carried out some and attempted overcoming this problem, these trials comprise:
I) adopt synthetic, biologically-hard base (biologically-hard base) liquid substitute mineral oil, as the basal component (base) of slideway.Though this can reduce the aggregate level of micro-nutrients, crucial sulphur and phosphorus reagent still exist.The synthetic alkaline liquid is also too expensive for the system of " complete loss ".
Ii) adopt the metal working fluid enriched material as slideway.Though this has overcome pollution problems, suffer damage as the major function of slideway.These products can be easily by flush away, makes chute " exsiccation ", causes high frictional force between instrument/workpiece and restive.The emulsifying effect of this additional enriched material also can cause cutting fluid concentration (strength) to be increased to too high degree.
Iii) adopt oil skimmer vessel/oil separator.This has different variations at price and aspect of performance.The simplest and the most cheap type is belt or disc type oil skimmer vessel, and these oil skimmer vessels are directly immersed in the machine storage tank, divides from the surface of metal working fluid and takes out free oil.These oil skimmer vessel/oil separators aspect of performance be restricted be since only under the situation of not stirring the shadow region of storage tank (promptly) or liquid saturated by oil, oil could be isolated from liquid.
Be extracting liq and remove the stand-alone machine of all oil contaminants from the machine storage tank on the other hand.These stand-alone machines can be fixedly to be exclusively used in a unit, or according to removable to serve many machines in shifts.Though these machines can be removed pollutent effectively from liquid, the price of these equipment is every and is tens thousand of sterlings.This can mean even also be sizable capital investment for the moderate engineering shop of scale.
Iv) use antiseptic-germicide in cutting fluid, antiseptic-germicide is the reagent of the chemical preparations, particularly concentration-type of danger, and in order to keep the function antiseptic-germicide to need to add with correct dosage.
Prevent that the most effectual way that microorganism grows from being to add antimicrobial compounds in this liquid in metal working fluid.Adding the most general place of antiseptic-germicide in liquid is in household and industrial environment.
Document-A-US 4968323 discloses use of insecticide composition or sanitas in hydrocarbon fuel and metal working fluid.Sterilant is joined in the fuel such as home heating oil, diesel-fuel and rocket engine fuel, and these fuel are stored in the jar usually, have gathered one deck water in these jars below fuel.This piece document has also disclosed and added the bromo Pinacolone in emulsifiable oil, prevents growing of the middle bacterium of metal working fluid (as cutting fluid and roll extrusion liquid).The document has disclosed and added the bromo Pinacolone before or after metal working fluid pollutes.
Document-A-US 4414121 discloses in the water-base metal lubricant and has added antiseptic-germicide, grows therein to prevent microorganism.
Document-A-US 5508417 discloses a kind of wide spectrum isothiazole antiseptic-germicide, can adopt this antiseptic-germicide to stop the invasion and attack of microorganism under many circumstances, normally uses this sterilant a kind of in such as carriers such as water or solvents.
Document-A-US 4946612 discloses a kind of difunctional oil compositions, can be used for the lubricating oil of sliding surface simultaneously and be used for metal working fluid, solves the problem that contains two kinds of different solutions, and it is unfavorable separately to them that these two kinds of solution mix.Second kind of performance of this oil compositions is antibacterium or antimycotic.
Yet, in metal working fluid, adding antimicrobial composition and have problem, employed most composition is poisonous, and comprises dangerous chemical preparations.The amount of the antimicrobial compounds that uses in metal working fluid must be carried out careful monitoring, so that the first, this compound concentrations is enough high, thereby has enough anti-microbial effects; The second, this concentration can not exceed the degree that near the staff the machine of handling this compound is produced injury.
Summary of the invention

1. paraffin mineral oil is about 100cSt 40 ℃ of kinematic viscosity;
2. paraffin mineral oil is about 30cSt 40 ℃ of kinematic viscosity;
3. the slideway bag of buying from Ethyl Petroleum Agents Ltd.;
4. the polyisobutene tackiness agent of buying from Ethyl Petroleum Agents Ltd..
These samples carry out the antibiotic shaker test of anti Bacillus pyocyaneu Flugge then, and Pseudomonas aeruginosa is one of modal spoilage organism of finding in cutting fluid.
These oil samples are put into " groove " of diameter 10mm of the center of the agar plate of inoculating.Then with these dull and stereotyped cultivations 48 hours and visual inspection.To represent the anti-microbial activity of all samples around inhibitory area-bacterium zero growth-initial diameter 10mm groove, can record their diameter, thus the anti-microbial activity of sxemiquantitative ground sample estimates.

| A | 10mm | 0mm |
| B | 14mm | 4mm |
| C | 20mm | 10mm |
| D | 22mm | 12mm |
[note: in order to record anti-microbial activity, groove primary diameter must be deducted (so 10mm is null suppression).]
From these results, obviously sample C reaches best cost efficiency balance between sterilant consumption and anti-microbial activity.
One of main standard of selecting antiseptic-germicide is to guarantee the consistency of itself and slideway.In two main modules of this point is the resistance to abrasion and the breakdown of emulsion of oil.Sample A (untreated slideway) and sample C adopt following industrial standards experimental technique to test.
The breakdown of emulsion experiment (mixes 40mls oil and 40mls water in the graduated cylinder of 100ml.The volume of isolated water from oil/water mixture is noted at interval every 5 minutes.

Although slow down owing to add the speed of antiseptic-germicide water sepn, but demulsifying phenomenon takes place.In fact a little slow velocity of separation provides the longer time for antiseptic-germicide changes cutting fluid over to.
Carry out shell 4 balls (the shell 4 ball) wear test, to measure the abrasionproof performance of two kinds of lubricants.
Shell 4-ball wear experiment (60kg load running 15 minutes) sample A
| The ball numbering | Wearing and tearing scar size mm |
| 1 | 0.709×0.723 |
