Definitions

• the present invention relates; to manta-titwhen is useful in lubricating chemically coated; metal surfaces rior to deformation, and more'speificallyto a soap type lubricant whi'ch is capable of being applied to such metal surfaces by spraying without the formation of an e'ic es sive quantity of foam.
• a chemical coating such as a phosphate coating-by the use of aqueous so'a solutions; it is necessary that the aq eous soap soliiti'on have carefully controlled pH in order for the coating and the aqueous soap solntiorl'to interreact to form the desired lubricating metallic soap.
• This pH range is approximately 8.8 to 10.5 as measured by the appropriate Hydrion" pl-I papers (paper #460 for the lower numerical limit and paper #470 for the upper numerical limit),- and these limits correspond to a pH of 8.2 to 9.6 as determined-by using-a lithia-glass electrode pH meter.
• rosin acids in the amounts specified hereinafter, in aqueous soap solutions provides simultaneously the desired ratio of free fatty acid to total fatty acid to control the formation of foam and also provides the necessary pH to obtain the desired interreaction between the soap solution and the phosphate coating.
• the incorporation of rosin acid, unlike mineral or straight chainfatty acids, in an aqueous soap solution does not appreciably alter the pH of the soap solution throughout the desired pH range as discussed in greater detail below.- However, the amount of free fatty acid present and the ratio of free fatty acid to total fatty acid are greatly increased, and thus the requisite conditions for l0w;foam formation andtheformation of coatings of high lubricating value are fulfilled.
• Rosin acids which are suitable for the purposes of this invention may'beinthe form of commercialgum or wood rosin,- tall oil, or may be extracted from tall oil residues.
• the term' rosin acid is intended in its generally understood sense, and may include such specific acids as abietic acid, neo abietic acid, pimaric acid, levopimaric acid, dextropimaric acid, isodextropimaric acid and mixtures thereof.
• compositions of this invention in the form of an aqueous concentrate which, upon the addition of water, produce the reactive solutions of lowfoaming characteristics above described are set forth in Formula I, the range of proportions of the various ingredients being given inparts by weight.
• compositions of this invention may optionally include other ingredients which are now conventional in drawing compounds in minor proportions, such as mineral oils, coloring and scenting compounds, etc.
• Mineral oils have been found to be desirable in quantities of about 2%10% by weight.
• the particular mineral oil which is employed is not critical.
• oils are availablecommercially under the designation of mineral oils and the specifications of a typical mineral oil which has been successfully employed in the compositions of this invention are as follows:
• compositions including mineral oil are set fOi'thiii Formula II.
• compositions given in Formulas I and II are relatively concentrated and may be concerted into a working solution for spraying on a phosphate coated surface by incorporating 30 to 460, but preferably to pounds of such compositions in gallons of solution.
• the ratio of rosin acids to fatty acids in the concentrates of Formulas I and II has been found to be critical to the successful spraying of the working solutions of this invention.
• the concentrate contains less than 3.5 parts of rosin acid per 22.5 parts of fatty acid, the foaming which is encountered on spraying a Working solution prepared therefrom is excessive.
• the reaction of the solution with the phosphate-coated surface is decreased to the point such that the resultant reacted coating is not of the desired character, that is, it is no longer a White velvety coating and can be easily removed from the surface with water.
• the method of this invention comprises the steps of spraying a working solution on a metal surface which has been preliminarily coated with a phosphate coating, an oxalate coating, a sulfide coating or an oxide coating at a temperature of about F. to 200 F. for sufiicient time to permit the sprayed lubricant to penetrate the coating and to bring the metal being sprayed up to the temperature of the lubricant, this usually requiring about 1 to 5 minutes.
• the temperature of operation is not critical, spraying becomes more diflicult at lower temperatures because the solution tends to become somewhat thicker and drains from the work at a much slower rate.
• the solution is allowed to-drain therefrom after which the reacted coating should be dried. Drying may be accomplished by allowing the article to remain at room temperature for a sufficient length of time, or by the use of heated air or a dry-01f oven maintained at a temperature of about F. to 225 F.
• it is necessary to control both the pH and the free acid content respectively in order to obtain the maximum reactivity with the phosphate coating and to avoid the formation of excessive quantities of foam.
• the pH should be maintained in the range of 8.8 to 10.5 and preferably in the range of 9.4 to 10.0 as determined by the use of Hydrion pI-I papers and the free acid should be maintained in a definite relar tion to the Babcock number as defined below.
• the active ingredients of the solution are gradually consumed.
• the Babcock number is pref erably maintained in the range of 2.5 to 3.0, and as the Babcock number decreases below 3.0, sufficient con- 4 centrated solution should be added to increase the Babcock number up to about 3.0.
• the free acid in the solution means the fatty acid which is uncombined and not in the form of a soap.
• Free acid in the operating solution is determined by adding 200 ml. of 99% isopropyl alcohol containing a small amount of phenolphthalein indicator to a 10 ml. sample of the aqueous working solution. This solution is then heated to boiling and titrated while hot with a 0.1 N aqueous solution of sodium hydroxide to the development of a permanent pink color. The number of milliliters of sodium hydroxide solution required to attain the permanent pink color is known as points of free acid. The free acid value, for best results, varies with the Babcock number and should be 0.3 to 1.3 points higher than the Babcock number.
• the free acid may be controlled by adding caustic soda or mineral acid to the working solution as required to compensate for dragin effects.
• the pH will be found to remain within the desired range of 8.8 to 10.5.
• the more eifective pH range of 9.4 to 10.0 is obtained when the Babcock number is maintained in the near vicinity of 3.0 and the free acid is maintained between 3.3 and 4.3, and these conditions represent the preferred operating conditions.
• Example 1 A soap concentrate was made up by admixing 225 grams of stearic acid, and 75 grams of gum rosin and 20 grams of mineral oil (specification given hereinbefore), 26 grams NaOH and 310 grams water at 200 F. to 210 F. for about 10 minutes with slow stirring to produce a thick paste at room temperature. The thick paste was then diluted with Water to 6 liters in volume and the working solution so formed was found to have a Babcock number of 3.2 to 3.5. The solution was sprayed at a tempeerature of 160 F. on a number of 4" X 6" mild steel panels, which had been preliminarily coated with a conventional zinc phosphate coating, for about one-half minute to one minute. The coatings were dried in an oven at 170 F. to 225 F. and inspected. The coating which was the reaction product of the zinc phosphate coating and the sprayed solution was gray to whitish in color and soft, velvety and capable of being crushed to a continuous unctuous film.
• Example 2 A 250 gallon working solution was prepared by adding 187 pounds of a concentrate, having the composition given below, to sufficient water to give 250 gallons of solution.
• the concentrate used contained 26.2 parts stearic acid, 10.5 parts rosin acid, 7.9 parts mineral oil (specification given hereinabove), 3.6 parts sodium hydroxide and 51.8 parts water.
• the tank containing this working solution was operated at a temperature between F. and F. as one unit in the continuous spray processing of annealed 76 mm. steel cartridge case components prior to drawing, the complete processing including the steps of pickling, rinsing, phosphate coating, rinsing and spraying with the solution of this tank for l to 3 minutes and drying.
• Example 3 A working solution was repared by admixing 300 grams stearic acid, 120 grams rosin acid, 90 grams mineral oil, 6 grams pine oil, 42 grams sodium hydroxide and 522 grams of water at 200 F. to 210 F. for about 10 minutes, and the admixture was then diluted to 8 liters with water. The pH of the solution was found to be 9.2. No excessive foaming was encountered in spraying this solution at 180 F. to 190 F. and the quality of the lubricating coating resulting from contacting phosphate coated panels therewith was found to be satisfactory for protecting the metal during relatively severe drawing operations.
• a plurality of panels were individually provided with an oxalate coating, others with a sulfide coating and' still others with an oxide coating, all processes for producing these coatings being conventional.
• these panels were contacted with the above composition at a temperature of 180 F. to 190 F., lubricating coatings suitable for protecting the metal during relatively severe drawing operations were obtained.
