Definitions
- the invention relates to the field of lubricants and more particularly for object that of the aqueous lubricants useful for the work or the shaping of metals.
- a lubricant in order to reduce the forces between the workpiece and the tool, remove chips and debris, cool and check the surface finish of the part or of the worked sheet.
- oil-based lubricants have been used. These are whole oils or emulsions to which oiling agents, anti-wear (AU) and / or extreme pressure (EP) additives have been optionally assistants.
- the lubricants form a monomolecular mat on the surface to be lubricate and thus reduce wear and friction. When the conditions of friction become more severe, the rise in temperature causes a desorption of these lubricants, and AU or EP additives (generally compounds containing phosphorus, chlorine or sulfur) are then necessary to lubricate the contact.
- AU additives reduce heavy wear of the parts in contact; EP additives can cause some wear but prevent welding and adhesion phenomena.
- the whole oils have excellent lubricating properties but, when rates are high, the evacuation of heat requires the use of emulsions. However, the use of emulsions also tends to be reduced because, over time, they degrade and cause bad odors.
- aqueous fluids which are either synthetic fluids (aqueous solutions based on soluble additives in water), or semi-synthetic fluids (oil-in-water microemulsions containing a large quantity of emulsifiers).
- synthetic fluids aqueous solutions based on soluble additives in water
- semi-synthetic fluids oil-in-water microemulsions containing a large quantity of emulsifiers.
- the aqueous fluids evacuate heat very well and have improved resistance to bacterial growth, their use is often limited to metal working operations where friction and wear conditions are not too severe.
- the additives AU and EP having been developed for oils, very few of them are soluble in water and suitable for aqueous fluids.
- the phosphoric acid esters obtained by reaction of a fatty alcohol, ethoxylated or not, on P 2 O 5 . They are soluble in water by neutralization in the form of alkaline salt, ammonium or alkanolamine or else thanks to their ethoxylated part. Widely used in aqueous metal working or shaping fluids due to their AU, emulsifying and corrosion-inhibiting properties, these esters are however not suitable for operations where the friction and wear conditions are very severe.
- alkylthio-acids which are monosulfides consisting of an alkyl chain generally comprising between 6 and 18 carbon atoms and a carboxylic acid group. Soluble in water by neutralization in the form of alkali, ammonium or alkanolamine salts, they are used in aqueous working or metal forming lubricants for their AU and corrosion inhibiting properties. However, their EP capacity is insufficient for very severe operations.
- the subject of the invention is also an additive for a multifunctional aqueous lubricant. consisting of an aqueous solution of at least one water-soluble salt of dithiodiglycolic acid and at least one water-soluble compound chosen from the group consisting of the phosphoric acid esters (I) and their salts and by the salts water-soluble alkylthio-acids (II).
- alkali metal, ammonium or alkanolamine salts such as, for example, monoethanolamine, diethanolamine and triethanolamine.
- Phosphoric esters (I) are the most often mixtures of mono- and di-esters in proportions ranging from 10/90 to 90/10. When they are not by themselves water-soluble, these esters can be used in the form of alkali metal, ammonium or alkanolamine salts.
- alkylthio-acids (II) those in which n is equal to 1 are preferred. or 2 and the radical R 'contains from 8 to 18 carbon atoms.
- the alkali metal, ammonium salts are preferably used or an alkanolamine such as monoethanolamine, diethanolamine and triethanolamine.
- the mass ratio: dithiodiglycolic acid / compound (s) I and / or II can range from 1/1 to 20/1, but is preferably understood between 2/1 and 10/1.
- the concentration total mass in dithiodiglycolic acid and in compound (s) I and / or II can range from 0.01 to 20% and is preferably between 0.1 and 10%.
- the additive according to the invention can be stored in the form of a dilutable concentrate later in synthetic fluids (true solutions) or semi-synthetic fluids (microemulsions).
- This concentrate may contain additives conventionally used in synthetic or semi-synthetic fluids such as inhibitors corrosion, emulsifiers, lubricant additives, alkaline agents, anti-foaming agents, ...
- the total mass content of acid dithiodiglycolic and in compound (s) I and / or II can range from 1 to 50% and is preferably between 15 and 35%.
- Phosphoric esters sold by CECA S.A., are mixtures of mono- and diesters, predominantly monoester.
- Test 4 extreme pressure balls (ASTM D-2783):
- the ball-disc test consists of spinning a disc at constant speed under a ball on which a constant load is applied. The disc and the ball are immersed in the lubricant. A force sensor measures the coefficient of friction of the lubricated ball-disc contact.
- a steel shaft immersed in the lubricant rotates at constant speed between two V-shaped jaws on which a constant load is applied.
- the weight loss of the two ves and of the axis is measured and must be less than 20 mg so that the formulation has anti-wear properties.
- AL / MEA lauric acid
- MEA monoethanolamine
- Examples 1 to 5 which do not contain ADTDG salt all have a welding load of less than 250 kg and the formulations of examples 6 to 8 which do not contain compound I or II all have a charge before seizing less than 63 kg and a coefficient of friction greater than 0.1.
- Example 16 which contains a mixture of lauric acid salts and dithiodiglycolic acid does not have antiwear properties (last load before seizing ⁇ 63 kg and wear in Falex> 20 mg).
