Definitions
- This invention relates to water-miscible or aqueous metalworking lubricants.
- Aqueous metalworking lubricants are excellent culture media for microorganisms, and as emulsions and solutions must therefore be protected against microbial attack or they will lose their utility and toxicological problems may arise owing to infection of the aqueous metalworking lubricant.
- a biocide incorporated as an ingredient in the metalworking lubricant concentrate.
- a microbial infestation of an emulsion can cause considerable toxicological problems (rapid multiplication of microorganisms, occurrence of coliformic germs with the risk of human pathological infections), it results in a drop of the pH-value (increased corrosivity of the aqueous metalworking lubricant) and incomplete breaking of the emulsion (which in turn necessitates not only replacement of existing emulsion and loss of broken emulsion, but also inadequate machining efficiency and reduced tool service life).
- the speed of decomposition of the biocide depends upon the respective composition of the metalworking lubricant.
- the present invention seeks to solve this problem by improving metalworking lubricants of this type in respect of their microbial stability to prevent or hinder decomposition of the biocide during storage of the metalworking lubricant concentrate.
- a water-miscible metalworking lubricant containing mineral oil, emulsifier, solubilizer, corrosion inhibitor biocide and acidic components, characterized in that the acidic component comprises an acidic organic phosphoric acid ester in an amount of preferably 3 to 12% by weight of the composition and that the biocide comprises a formaldehyde liberating compound.
- Such a composition may have a composition in percentage by weight:
- compositions according to the invention provide prolonged inhibition of biocide decomposition by virtue of using instead of the conventional carboxylic acids (in particular fatty acids), acidic organic phosphoric acid esters. This markedly retarded biocide decomposition results in a considerably better microbial resistivity of the metalworking lubricants of the invention after storage as compared with conventional compositions.
- compositions contain no or only very minor amounts of carboxylic acids (in particular fatty acids), and instead, acidic organic phosphoric acid esters.
- Conventional water-miscible metalworking lubricants for metal machining contain biocides, predominantly formaldehyde liberating biocides, in the concentrate for protection against microbial attack of the working emulsions or solutions.
- These water-miscible metalworking lubricants contain also inter alia alkaline components (for example alkanolamines) as well as carboxylic acids (predominantly fatty acids), which perform a neutralizing, lubricating, and partly an emulsifying and corrosion inhibiting function.
- biocides which in most cases are selected by microbiological tests, impart to the working emulsions and solutions a good or at least adequate resistance to microorganisms provided that the emulsions or solutions are prepared from concentrates which are freshly prepared or stored for short periods only.
- the biostability of the working emulsions and solutions is, however, often unsatisfactory or at least no longer completely sufficient since due to decay of the biocide during storage the biocide concentration necessary for microbial protection in the working solution or emulsion (minimum restraint concentration) is no longer available.
- skimmers often containing silicon.
- skimmers often become ineffective even after brief use (since they become adsorbed and discharged or altered in their particle structure). There is therefore a need for metalworking lubricant formulations which do not froth per se and do not require the use of skimmers.
- biocides have also been investigated in which the effective mechanism does not reside in the release of anti-microbially acting formaldehyde.
- formaldehyde-free biocides either do not have the necessary broad spectrum activity (against all bacteria, fungi and yeasts usually occurring in machining emulsions) or have doubtful toxicological or ecological effects. Moreoever, these formaldehyde-free biocides often cannot be incorporated into concentrates.
- the decomposition rate of the biocides during storage of the concentrate can, to a specific extent, be influenced by the chemical composition of the concentrates.
- the presence or absence of certain components can favorably or unfavorably affect the decomposition speed.
- Cooling lubricant formulations of this kind do not have a frothing tendency (as emulsions or solutions) in laboratory tests or under practical conditions (even in complex situations, for example high emulsion concentrations and under unfavorable conditions, for example in drilling a deep blind hole) compared with conventional products.
- Acidic organic phosphoric acid esters are sometimes used as components for corrosion reduction (extreme pressure components) in metalworking lubricants.
- the stabilizing effect of acidic organic phosphoric acid esters on formaldehyde liberating biocides was not previously known.
- carboxylic acids especially fatty acids
- acidic organic phosphoric acid esters are at least substantially replaced by acidic organic phosphoric acid esters.
- Particularly suitable acid phosphoric acid esters for use in the compositions of the invention are monoalkyl phosphoric acid esters, dialkyl phosphoric acid esters, monoisoalkyl phosphoric acid esters, diisoalkyl phosphoric acid esters, monoalkenyl phosphoric acid esters, dialkenyl phorphoric acid esters, mono(alkylphenyl) phorphoric acid esters, di(alkylphenyl) phosphoric acid esters, mono (isoalkylphenyl) phosphoric acid esters, di(isoalkylphenyl) phosphoric acid esters as well as mono and dipolyether phosphoric acid esters, the polyether group comprising, if desired, as terminal group alkyl, isoalkyl, phenyl, alkylphenyl and isoalkylphenyl and hydrogen.
