Description
Patented Jan. 30, 1951 UNITED STATES PATENT OFFICE NONFERROUS METAL BURNISHING COMPO- SITION AND BURNISHING PROCESS No Drawing. Application April 19, 1947, Serial No. 742,736
8 Claims. (Cl. 51-282) pegs, wood chips, etc. It is the general objective 10 of such a burnishing treatment to perform two functions: first, the removal of any tarnish on the non-ferrous metal surface, and secondly the lusterizing, brightening or polishing of such surface, without causing the redeposition of a tarnish.
Heretofore such burnishing metal treatments have been carried out in an aqueous solution containing soap and sodium cyanide, or one containing a wetting agent such as ispropyl naphthalene sulfonate. The burnishing treatments accomplished by the use of such aqueous solutions however, have been found to be deficient in that they wouldnot accomplish both of the desired functions of removing tarnish and brightening of the metal surface without tarnish redeposition.
I have discovered that this dual function objective can be attained by performing the burnishing treatment in an aqueous solution containing a synthetic organic wetting agent, preferably one derived from a long chain alkoxy compound, and containing an alkylenepolyamine. Only very small amounts of such wetting agent and alkylenepolyamine need be present in the aqueous solution to achieve the desired result. Thus ODDS-0.05% by weight (all percentages herein given by weight unless otherwise specified) of alkylenepolyamine and 0.05-0.1% of long chain alkoxy-derivative wetting agent, represent suitable and operative range concentrations of these ingredients.
In making up a composition suitable for use in the burnishing operation, i. e., by further dilution with water, a composition consisting of 5-20 parts by weight of wetting agent and 5-2 parts of alkylenepolyamine, represents preferred range proportions. When such composition is to bemade in liquid form, as a concentrated stock solu- .tion for use by the burnishing operator, then water may be added to the'last given range proportions of ingredients in a quantity suflicient to make a total of 100 parts.

As the alkylenepolyamine ingredient of my composition, it has been determined that ethylene diamine, propylene diamine and triethylene tetramine are most suitable and to be preferred.
Monoethanolamine is preferably added to the composition of my invention as a stabilizing and an alkaline pH control agent, and in an amount equal to one-half that of the wetting agent; or in a range proportion of 0.025-0.05% concentration in the final burnishing solution.
In order to determine the operability and emciency of the compositions of my invention, they have been subjected to a tarnish removal test" and luster test, the conditions and specifications of which are as follows:
Tarm'sh removal test Specimens of brass plate, measuring 3" x 1 with on each of the 1 width ends bent over at right angles, are placed in a rubber lined, closed tumbling barrel together with 50 lbs. of diameter steel balls. This tumbling barrel, mounted on a horizontal axis, is driven at a speed of 30 R. P. M. The specimen brass plates before charging into the barrel, are first degreased with an alkaline detergent, and then given a tarnish by the following procedure:
1. Immersed in a 2% caustic soda solution at 35 C. and subjected to a 2.8 ampere current for 1 minute, with the brass specimen as the anode.-
2. Subjected to the same electrolytic treatment in the same caustic soda solution for 1 minute, but at a current of. 0.25 ampere.
3. Removed from caustic soda solution, held in the air for 1 minute and rinsed oil with water.
The burnishing composition is made up at a concentration of 1 liquid ounce per gallon in tap water of medium hardness (approximately 7 grain hardness) in an amount to make two liters ingredient of my composition is commercially of solution which is then added to the tumbling available under various trade names, such as barrel whereupon the tarnished brass specimens,

A stock solution was made up consisting of 10% of the same wetting agent as employed in the results shown in Table I, plus 5% monoethanolamine, and varying percentage proportions of different alkylenepolyamines. These solutions were then similarly tested and with the following results:

mensions as under the tarnish removal test specifications given above are degreased with an alkaline metal cleaner and then dipped for seconds in a 10% sulfuric acid solution at room temperature, in order to remove any tarnish. The so-treated brass specimens are then subjected to a one hour burnishing treatment in the rubber-lined tumbling barrel described above. Average initial and final reflectance readings are similarly obtained upon these so-treated samples. The increase in reflectance constitutes a measure of the efliciency of the burnishing action, and the presence or absence of a tarnish on the burnished specimen is visually observed in order to determine whether there has been a redeposition of tarnish from the burnishing treatment.
Several difierent alkyl amines in the amount of 2% were added to a 10% stock solution of wetting agent consisting of a sulfonated condensation product of an alcohol and higher fatty acid (Cerfak N-101).
