Definitions

  • This invention relates to the preparation of anti-corrosion preparations for protecting metal surfaces against corrosion and particularlyto prevent rusting of articles or surfaces of ferrous metals.
  • lubricating oils may be used. If two pieces of polished steel are taken and one of them immersed entirely in lubricating oil and the other is simply coated with a thin film of oil, e. g., by rubbing with a pad impregnated with lubricating oil, the plate entirely immersed is protected against rust for a very long time, while the plate which has simply been coated With a thin layer of oil becomes covered with rust after a very short exposure to the air.
  • the present inventors have discovered that there are two groups of compounds which, when mixed, are capable of producing the desired con ditions of preferential displacement of water by oil on the surface of the metal,
  • the first group of compounds comprises those which are soluble in the oils and insoluble in Water and which have also a great affinity for the metal surface.
  • the compounds capable of fulfilling these conditions are:
  • resinic acids e. g., abietic acid, etc.
  • Cresols extracted from wood tar such as the thio-cresols, alkyl phenols, mercaptans, or compounds corresponding to the formula I-ISR, R being an aliphatic radical having more than 5 carbon atoms and which may be substituted in the organic radical of these products, may contain one or more of the substitution groups such as: O, OH, N, S, 00, CL, and the like.
  • Polyvalent metal salts of the above acids such as salts of lead, copper, iron, tin, zinc, manganese, mercury, and the like, are' better agents than the similar acids. These salts can be prepared by double decomposition or by direct action of the metal, or better still its oxide, with the difierent acids, phenols, thio-phenols or mercaptans (in general the basic salts react better than the acid salts).
  • ether salts corresponding to the acids indicated above in particular, to ether salts of higher alcohols and most particularly, polyalcohols of natural, animal or vegetable origin, such as, suintine, lanoline, spermaceti oil, spermaceti wax, beeswax, Chinese wax, and the like, or of synthetic origin such as the ether salts of pentaerythritol, cholesterol, and the like.
  • Amines and imines of higher molecular weight, having more than 6 carbon atoms in the molecule, and their salts with the organic acids mentioned above such as heptadecylamine oleate, and the like, alkyl pyridine bases and their homologues, such as cetyl pyridine, and the like, and their salts with the organic acids indicated above, ammonium bases and pyridinium bases having more than 10 carbon atoms in the molecule, and their salts with the organic acids mentioned above.
  • the second group of compounds comprises compounds superficially active vis-a-vis the water by having a sufiicient solubility in the oil.
  • bases such as sodium, potassium, ammonium, lithium, calcium, quaternary ammonium bases, oxonium, urea and imines, and the like with:
  • the process according to the invention consists in mixing from 120% of any one or more of the many compounds of each of these two groups with a lubricating oil. In this manner there are obtained products possessing anti-rust properties greatly superior to those of the pure oils and equally superior to those obtained when using a mixture of the compounds of only one category. A plurality of compounds of each category may also be employed.
  • the comparative efiiciency was determined by the following method:
  • suintine suint
  • lanoline a mixture of suintine (suint) and lanoline on the one hand and sulfonate of soda on the other hand, being already known, these are used for comparative purposes.
  • the oily base may comprise petroleum mineral oils or synthetic oils covering all ranges of viscosities from spindle oils (very light lubricating oils) up to cylinder oils.
  • Mixtures of anti-rust oils, such as those obtained from petroleum or parafiin to obtain products of a Vaseline-like consistency may also be used which may, if desired, be'diluted with a solvent such as gasoline, white spirits, gas-oil, or other appropriate solvents.
  • a drying oil may also be used. In this manner, with the addition of pigments generally employed in paints, excellent anti-rust paints may be obtained.
  • Excellent industrial anti-rust oils, petrolatums, waxes, and ordinary or bituminous or tarry paints can thus be obtained by adding, during or after manufacture, mixtures of from 0.1 to 20% by weight, based on the total composition, of one or more of the compounds of each of the two groups mentioned above.
  • composition according to claim 6 wherein said oily vehicle comprises petrolatum.
  • a corrosion inhibiting composition consist-.
  • a rust inhibiting composition consisting essentially of a mineral oil base vehicle containing 0.1 to 20% by weight of at least one metal sulfonaphthenate selected from the groups which consist of lead and sodium sulfonaphthenates and 0.1 to 20% of a material selected from the group which consists of lanoline and suintine.
  • a rust inhibiting composition consisting essentially of a light mineral base lubricating oil containing about 5% by weight of sodium sulfonaphthenate and about 10% by weight of suintine, based on the weight of the total composition.
  • a rust inhibiting composition consisting essentially of a light mineral base lubricating oil containing about 10% by weight, based on the total composition, of sodium sulfonaphthenate and abo 5 of lanoli e.
  • Composition according to claim 8 to which is added about 2.5% of lead sulfonaphthenate.
