Description

Patented Oct. 8, 1946 2,408,971 SLUSHING COMPOSITION Gordon W. Duncan, Scotch Plains, N. J., assignor to Standard Oil Development Company, a corporation of Delaware Application December 27, 1941, Serial No. 424,595
8 Claims. (Cl. 106-14) No Drawing.
The present invention relates to slushing compositions, particularly to those compositions applied to the surface of easily corrodible metals for arresting, preventing, and inhibiting the corrosion thereof.
The corrosion of the metal is considered to be the result of chemical reactions between the environment surrounding the metal, and the metallic surface due to differences in electro-motive forces in and about the surface of the metal. By coating metallic surfaces with an inert impervious film the development of these electro chemical relations can be impeded and arrested and thus active corrosion prevented. The use of a slushing composition usually involves the formation of a viscous liquid or semi-solid layer on the metal which is easily removable from the surfaces over which it is spread by wiping with a. cloth or flushing with a solvent.
In the application of slushing compositions the removal of adherent moisture offers some difficulty. In the fabrication of many metal machine parts it becomes necessary, as in the case of certain roller bearings, to electroplate a portion of the surface in an acid electroplating bath. After the electroplating operation is complete and the machine part removed from the bath, a Washing operation is required to remove the adherent plating solution. It may then be necessary due to the character of the machine part to completely disassemble and dry it prior to the application of an anti-corrosion composition. Many other metal stock parts are water-washed during fabrication and this adherent moisture is customarily removed by oven drying over an ascertained period of time or by the application of a volatile liquid miscible with water and air-blowing. It would be much more convenient to apply a slushing compound capable of absorbing or dislodging adherent moisture directly from the metal. Articles that are manually moved or handled often are contaminated with moisture or perspiration from the hands of operating personnel. Subsequent slushing with a rust-proofing composition will not prevent rusting at these fingerprint marks unless the rust preventive is capable of absorbing or dislodging moisture directly from the metal.
It is an object of the present invention to pro- Vide an anti-corrosion composition or slushing compound for metals which will readily dislodge water and aqueous solutions from contact with metal surfaces. This and other objects will be apparent to those skilled in the art upon reading the following description.
It has now been found that the addition of a small amount, from 1 to 10%, of a compound partially or wholly soluble in both water and mineral oil distillates to an anti-corrosion composition or slushing compound results in an improved slushing compound having the characteristic of completely conditioning a ferrous metal surface against corrosion even in the presence of adherent water or aqueous solutions. Substances having the properties requisite for the purposes of the present invention and boiling within the range of from 100 C. to 300 C. possess the formula ROalky1ene0-R where R is either hydrogen or an alkylolradical such as ethanol; alkylene represents a bivalent radical such as =CH2(methylene),
H CH3 CH:-CH:-, -*JJ-',
CH3 etc., and R. is either hydrogen, an alkyl radical, such as methyl, ethyl, propyl, etc., or an aryl radical such as 'phenyl. In instances where both R and R are hydrogen the alkylene radical should contain at least 4 and not more than 10 carbon atoms. Specific representative compounds of this class of materials are monomethyl ether of ethylene glycol, monobutyl ether of ethylene glycol, mono-ethyl ether of di-ethylene glycol, l-phenoxy Z-hydroxy propane and 2-methyl 2,4- pentane diol.
The compositions of the invention are, therefore, improved slushing oil compositions which contain, in addition to a petroleum or fatty oil base and anti-rust agents, preferably of the metallic sulfonate type small amounts of both oiland water-soluble dihydroxy alcohols (diols) of from 4 to 10 carbon atoms, mono-others of glycols or mono-ethers of ether-glycols. A specific instance of an anti-rust composition which is appreciably improved by the addition thereto-of the compounds of this invention. is that disclosed'in Patent 2,182,992. The compositions therein disclosed are composed of a petroleum oil of lubricating oil consistency blended with a fatty compound, such as degras, and mahogany soap such as an alkaline metal soap of theoil-soluble sulfonates derived from petroleum by treating oils with concentrated sulfuric acid. The following formula is a specific example Per cent Petroleum oil (750 seconds Saybolt at 100 F.) 50% oil solution of sodium salts of oil-soluble sulfonic acids formed on treating petroleum stocks with concentrated sulfuric acid 10 Degras 5 In compounding the compositions of the invention all that is necessary is to dissolve from 1 to 10%, preferably from 2 to 4%, of the additives previously described to a slushing oil composition such as disclosed in Patent 2,182,992 or other commonly employed slushing oil composition.
The efiicacy of the slushing oil compositions of this invention is evaluated bycertain standard tests of which the water displacement test and corrosion test are the more important. In the water displacement test, sand blasted panels of hot rolled steel are dipped in tap water or other aqueous solution and are immediately immersed suspended in the slushing compounds for 100 seconds and the time required to displace the water or aqueous solution is noted by visual inspection. The panels are then-suspended vertically for two hours in the atmosphere, .then washed with naphtha, and examined for signs of corrosion. In a series of tests, the effects of several of the additive substances falling'within the scope of the invention in solution in a slushing oil composition consisting of 80% petroleum solvent, mahogany soap concentrate and 10% degras were investigated with the results given below. In all cases where corrosion does not occur within the two hour period the slushing compound film was found to give rust preventive results comparable to that obtained when a dry panel was coated with the slushing compound not containing the additive.
'4 petroleum fraction to which is added degras, a metal salt of oil-soluble sulfonic acids derived from petroleum by treating petroleum stocks with concentrated sulfuric acid and from 1 to 10% of a compound having the formula RO-alkylene--OR wherein R is selected from the group consisting of hydrogen and alkylol radicals; and R is selected from the group consisting of hydrogen,
. alkyl, and aryl radicals.
