Definitions
- the invention relates to the use of polyhydroxycarboxamides as a high pressure additive, especially for lubricants, Metalworking fluids and hydraulic fluids.
- High pressure additives also internationally in the professional world "EP-Additive” (Extreme-Pressure-Additives) fluids, e.g. Gear oils, motor oils, metalworking oils and hydraulic fluids added to to give them a high load capacity, which when transmitting large forces is necessary to avoid that touching metal surfaces weld together and are subject to uncontrolled wear.
- EP-Additive Extreme-Pressure-Additives
- Lubricant additives are known from US Pat. No. 4,647,389, which are prepared by reacting a natural oil, for example coconut oil or palm oil, with a C 2 -C 10 -hydroxy acid and a polyamine. These are hydroxyacylated fatty acid amides of polyamines, which act as friction modifiers in lubricating oil compositions, but not as EP additives.
- U.S. Patent 4,512,903 discloses hydroxyacylated amides from primary and secondary fatty acid amines as lubricant additives known, which also act as a coefficient of friction, but not as EP additives.
- polyhydroxycarboxamides the so far as sugar substitutes and dietary nutrients have been used as a high pressure additive (EP additive), especially for lubricants, metalworking oils and hydraulic fluids can be used can.
- EP additive high pressure additive
- polyhydroxycarboxamides are known, e.g. from international patent application PCT / US91 / 07534 as WO 92/06601.
- the amides which can be used according to the invention as EP additive of Polyhydroxycarboxylic acids can be N-unsubstituted amides, however, they are preferably N-substituted Amides, especially alkyl and dialkyl amides with alkyl radicals with 1 to 4 carbon atoms, as well as monohydroxyalkylamides and polyhydroxyalkylamides, aminoalkylamides and aminohydroxyalkylamides, in each case the respective Alkyl radical has 1 to 4 carbon atoms.
- Polyhydroxycarboxamides which are particularly preferred according to the invention are:
- At least one of the polyhydroxycarboxamides is preferred in an oily or aqueous composition included, e.g. in a lubricant, an engine or Gear oil, a metalworking oil or metalworking fluid or a hydraulic fluid, these Fluids also in the form of an emulsion, e.g. a water-in-oil emulsion or an oil-in-water emulsion.
- Such an oily or aqueous composition preferably contains still at least one anti-corrosion agent, wherein Boric acid esters are particularly preferred as corrosion inhibitors are.
- the composition can at least contain an emulsifier.
- the at least one polyhydroxycarboxamide is preferred used in such an amount that the amide content up to 70% by weight of the respective composition. Prefers however, the composition is applied diluted with water, wherein the amide content 0.01 to 3.0 wt .-% of the respective Composition.
- the polyhydroxycarboxamides used are chiral Compounds that have at least one asymmetric carbon atom own and therefore in the form of enantiomers and in Form of racemates can be present.
- the most preferred Gluconamides and glucoheptonamides can therefore be found in the D- or L-form or as a D, L-racemate.
- the invention further relates to a high-pressure additive (EP additive), especially for lubricants, metalworking fluids and hydraulic fluids that are at least one Contains amide of a polyhydroxycarboxylic acid, but preferably additionally at least one anti-corrosion agent and / or contains at least one emulsifier.
- EP additive high-pressure additive
- Emulsifier can be any of the usual ones known for this purpose Emulsifier and any usual and for this purpose known anti-corrosion agents act, provided that these additional agents with the polyhydroxycarboxamides are chemically compatible, what by simple, the Preliminary tests familiar to a specialist can be determined quickly can.
- the additive according to the invention particularly preferably contains additionally at least one polyalkylene glycol, e.g. Diethylene glycol, polyethylene oxide and / or polypropylene oxide or similar.
- polyalkylene glycol e.g. Diethylene glycol, polyethylene oxide and / or polypropylene oxide or similar.
- the proportion of the at least one amide is preferred 0.01 to 70 wt .-% of the high pressure additive.
- the additive according to the invention preferably contains one of the the aforementioned gluconamides or glucoheptonamides.
- the polyhydroxycarboxamides used according to the invention can be produced as in the publication WO 92/06601.
- the preparation of N-2- (hydroxyethyl)] - D-gluconamide can be done, for example, that one mole of D (+) - gluconolactone, which is insoluble in methanol, Methanol is added and heated to 65 ° C with stirring becomes.
- the suspension of the lactone slowly becomes 1 mol ethanolamine, which is dissolved in methanol, added. It takes place a spontaneous exothermic reaction takes place during its course the gluconolactone dissolves completely.
- About amide formation To complete, reflux is continued for two hours touched. Then the solution is slowly becoming permanent Stirred cooled, whereby the solid amide precipitates out of the solution.
- the solution is then filtered and the residue washed twice with methanol. Yield: 95% pure N- [2- (hydroxyethyl)] - D-gluconamide, hereinafter referred to as "HEGA”.
- Cool 1 is an emulsion based on mineral oil that contains 15% Mineral oil, anti-corrosion agents (boric acid esters) and emulsifiers contains.
- Cool 10 is an ester-based cutting oil, containing 10% Esters, emulsified in water, as well as corrosion inhibitors and Emulsifiers.
- Cool Syn 100 is an aqueous system based on polyalkylene glycol with anti-corrosion agents, but without emulsifiers.
- the Reichert Friction Wear Test is carried out as follows: A roller or roller made of metal is firmly against a rotating sliding ring pressed, the lower third immersed in the fluid to be examined. The speed of rotation the slide ring is set so that the Contact point and thus the point of friction Abrasion between roller and slide ring from the fluid whose Load capacity should be tested, achieved and is wetted.
- the slide ring rotates on the Roll elliptical abrasion surfaces, the size of which depends on the load capacity depends on the fluid to be tested. The smaller the abrasion surface after a defined time or after a defined distance, the greater the load bearing capacity.
- the noise distance sets another parameter that is used in the Reichert friction wear test is measured.
- metallic Noise until a reaction film is formed from the fluid to be tested has formed between the slide ring and roller.
- the Orbital distance covered by the slide ring up to this noise suddenly stops, is called a "noise route" designated. The shorter this route, the better the fluid is suitable as an EP additive.
- pure Water does not form a reaction film, so the noise can be heard over the entire test distance of 100 m.
- Example 1 consists of 95% by weight of Cool 1 and 5% by weight HEGA
- example 2 from 90% by weight Cool 1 and 10% by weight HEGA
- example 3 consists of 95% by weight of Cool 10 and 5% by weight of HEGA
- example 4 from 90% by weight of Cool 10 and 10% by weight of HEGA
- example 5 from 95% by weight of Cool Syn 100 and 5% by weight of HEGA
- example 6 from 90% by weight of Cool Syn 100 and 10% by weight of HEGA
- Example 7 from 80% by weight of Cool Syn 100 and 20 wt% HEGA.
- both the noise distance and the abrasion area drop to 14 m or 12 mm 2 even at a very low concentration of 5% HEGA.
- An increase in the concentration from 5 to 10% HEGA leads to a further reduction in the noise distance to 10 m, while the abrasion area remains the same at 12 mm 2 .
- a further increase in the HEGA concentration to 20 or 30% only slightly improves the noise path and the abrasion area. It follows that the effect achieved with the use of polyhydroxycarboxamides according to the invention occurs even at very low concentrations and that an increase in the concentration is in most cases not economically sensible since the best compromise between cost and benefit is achieved even at the lowest concentrations. This is of great importance for the technical use of the EP additives according to the invention.
- polyhydroxycarboxamides as EP additives thus offers the following advantages: the additives used are readily biodegradable, they are water-soluble, so that, as a rule, neither emulsifiers nor anti-foaming agents are necessary, they are inherently non-foaming, and they are particularly easy to use for the processing of iron and ferrous metals and they are non-toxic, as is shown in particular by their known use as sugar substitutes and dietary nutrients.
- the amides used according to the invention can be used in anhydrous but also in aqueous metalworking fluids, in hydraulic fluids, in textile machining fluids and in fluids for cutting and grinding metals and glass. Example No.
