Definitions

  • the present invention relates to a lubricant. More in particular, it relates to a lubricant useful in the metal deformation work, such as stamping and forging.
  • the lubricant is used to facilitate the deformation work, reducing the friction forces between punch, metal and die.
  • composition aqueous polishing-cooling comprising, in weight percent, 0.1 to 0.5% monoethanolamine, 0.1 to 0.5% hexamethylene tetramine, 0.1 to 1.5% fat itself containing 50.1% phospholipids, the balance being some water.
  • non-oil-based lubricant based on phospholipid and a organic or mineral basic compound, suspended in the water.
  • Phospholipids are polar compounds whose molecule has a lipophilic fraction and a fraction hydrophilic. They are not soluble, but dispersible in water.
  • organic basic compound is meant here the amines and their derivatives.
  • basic mineral compound is meant a base of a metal from group IIa of the periodic table of the elements.
  • the lubricant of the invention can be removed from stamped metal using a solvent aqueous, thanks to its hydrophilic fractions.
  • a solvent aqueous thanks to its hydrophilic fractions.
  • biodegradable so it does not pose environmental issues.
  • An object of the invention is therefore to provide a lubricating composition consisting of a suspension in water from a mixture of phospholipids and a compound basic mineral or organic.
  • the phospholipids are present in the form of lecithin; the lecithin is soy lecithin; the basic compound is at least partially in suspension; the compound basic is an amine or an amine derivative; the compound basic is a hydroxide of a group IIa metal of periodic table of elements; the composition includes plus an acid, to neutralize the alkalinity of the compound basic after its interaction with phospholipids.
  • Raw soy lecithin is a mixture of approximately 60% by weight of polar lipids (insoluble in acetone) consisting essentially of phospholipids, and about 40% by weight of non-polar lipids (soluble in acetone) made up of oil, free fatty acids and sterols.
  • the lecithin phospholipids are glycerophospholipids of general formula wherein either X and Y each independently represent an acyl radical of palmitic acid, stearic acid, oleic acid, linoleic acid, linolenic acid and the like, or Y represents hydrogen, and X a acyl radical as above; Z represents choline, ethanolamine, inositol or hydrogen.
  • lecithins are used mainly for their emulsifying properties (due the presence of hydrophilic fractions and fractions lipophilic), for example in lubricants and the food industry, and also as a basis ointments.
  • the presence of the basic compound makes the pH of the lubricating composition alkaline, and it may be useful to add an acid to neutralize the composition.
  • This acid has no other function than neutralization, and will therefore generally be arbitrary, provided that it has no undesirable side effects. Without being limited thereto, it is thus possible to use H 2 SO 4 , H 3 PO 4 , CH 3 -CH 2 OH, CHOOH, and the like.
  • any neutralizing acid should be added to the lubricant composition, that is to say after setting suspension of the mixture of phospholipids and compound basic, and not the basic compound alone, before its incorporation into the composition.
  • the inventors have in effect noticed that if the acid is added to the compound basic before adding the latter to the phospholipids in suspension, the lubricating effect is not reached.
  • calcium stearate is for example known as thickener for oil, but has no synergy with the phospholipids according to the invention.
  • a composition based on calcium carbonate salts or tricalcium phosphate does not provide lubrication effective. This is to be compared to a composition according to the invention, containing calcium hydroxide, which retains its lubricating properties even after neutralization, as will be seen below.
  • the lecithin used in the lubricant of the invention is defatted lecithin, to facilitate suspension in water.
  • lecithin can also be modified lecithin, by example to improve its hydrophilic properties, and therefore its dispersibility in aqueous and polar media. So we can use hydroxylated lecithin, hydrolyzed, acetylated or the like. Modified lecithin may also be degreased or not.
  • the phospholipid / basic compound ratio is a important parameter of the invention, insofar as it there is a synergy between the two components, and where the lubricating effect is absent below a certain proportion of basic compound.
  • Water on the other hand, only has a diluting effect, and does not not change the lubrication properties, so the quantity of water is not an important parameter of the invention.
  • the amount of water just needs to be chosen depending on the desired fluidity, and therefore the applicability of the lubricant to metal surfaces. So when the amount of water becomes low, by example of the order of 20% by weight of the composition total, the composition becomes very pasty, and difficult to apply; on the other hand, when the amount of water becomes too large, for example of the order of 90% by weight of the total composition, the lubricant becomes too diluted, and there is no longer enough of the "active" component of phospholipids / basic compound to ensure lubrication. The amount of water will therefore be adjusted each times depending on requirements and method of application (spraying, sprinkling, brushing, and the like).
  • the lubricating compositions of the invention will also contain adjuvants classics, such as antioxidants, agents anticorrosion, and the like.
  • test tubes used for the stamping test were test pieces made up of 70 mm diameter discs and 0.8 mm thick, made of 304 stainless steel.
  • the lecithin used in the examples is defatted soy lecithin, containing 97% or more weight of polar lipids, marketed under the name LIPOPUR by the company Lucas Meyer.
  • the test consists of training, using the press stamping, cylinders with a diameter of 35 mm and a depth of about 32 mm (the depth varies with the lubricant quality).
  • Example 1 (reference) - Deep drawing using a known oil-based lubricant
  • the conventional lubricant is replaced with a lubricant consisting of 20% by weight of lecithin soy and 80% by weight of water.
  • the test fails by breaking the metal.
  • the conventional lubricant is replaced with a lubricant consisting of 20% by weight of hydroxide calcium and 80% by weight of water.
  • the test fails by breaking the metal.
  • Example 4 (invention) - Use of lecithin + mineral base
  • the conventional lubricant is replaced with a lubricant according to the invention, consisting of 10% by weight of soy lecithin, and 10% by weight of hydroxide calcium in 80% by weight of water
  • this lubricant shows superior to conventional lubricant, since the force necessary for stamping is significantly less than in the case of Figure 1.
  • the conventional lubricant is replaced with a lubricant according to the invention, consisting of 10% by weight of soy lecithin, 10% by weight of stearylamine (a stearylamine put on the market by the company Hoechst, under the trade name Genamin SH 100 and 80% by weight of water.
  • a lubricant according to the invention consisting of 10% by weight of soy lecithin, 10% by weight of stearylamine (a stearylamine put on the market by the company Hoechst, under the trade name Genamin SH 100 and 80% by weight of water.
  • this lubricant shows substantially equal to conventional lubricant, since the force necessary for stamping is equal to that required in the case of Figure 1.
  • the diagram in Figure 6 shows the result of a test carried out on a composition according to Example 4, neutralized to pH 8 with phosphoric acid.
  • FIG. 7 shows the result of a test carried out on a composition according to Example 5, neutralized to pH 8 with phosphoric acid.
  • the purpose of this example is to show the effect of a neutralization of the basic compound before formation of the composition.
  • calcium pyrophosphate Ca 3 (PO 4 ) 2 is mixed at 10% by weight with 10% by weight of lecithin and 80% by weight of water, to obtain a composition made up of the same elements as that of l example 6, but with salt instead of hydroxide.
  • the test is negative insofar as the test piece breaks.
  • lecithin alone (example 2)
  • calcium hydroxide alone (example 3) are not useful as a drawing lubricant, except 20% by weight in water
  • the combination according to the invention (Example 4) of lecithin and hydroxide calcium in the same proportions (20%) gives a lubricant superior to conventional lubricant, since requires less drawing force, and therefore requires minus the metal.
  • the effect lubricant is substantially independent of the concentration phospholipid and basic components, such as show the diagrams of Figures 9 and 10, relating in trials in which the proportion of the compound basic, namely calcium hydroxide and stearylamine, respectively, was increased to 20%.
  • the limit is here that imposed by the fluidity and applicability of the composition.
  • the basic compound to be used according to the invention is will generally be found commercially in the form of a dry powder.
  • the granulometry of the powder is not in itself not a parameter of the invention.
  • the inventors observed that as the particle size increases, you must allow a longer period of time to elapse between the preparation of the composition and its use, as if it took more time for a reaction to produce, between phospholipids and the surface of basic compound particles.
  • the inventors have tested various basic compounds, and found that the best results were obtained with compounds not completely soluble in the suspension phospholipids in water, at least part of which therefore remains in suspension, or else which form a mixture heterogeneous with suspended phospholipids.
