Description
United States Patent 3,265,475 BUFFING COMPOSITIONS Donald H. Schantz, Grand Rapids, Mich, assignor, by mesne assignments, to Hanson-Van Winkle-Munning Company, a corporation of New Jersey No Drawing. Filed Dec. 4, 1962, Ser. No. 242,106 9 Claims. (Cl. 51-304) This invention relates to bufiing compositions and, more particularly, to both non-aqueous and aqueous bufiing and polishing compositions which may be easily and completely removed from "a metal workpiece by an aqueous alkaline cleaning solution. The invention is based upon the discovery that either aluminum or zinc powder, when incorporated in minor amounts in either a non-aqueous or an aqueous buffing composition, are capable of generating sufficient hydrogen gas when a metal workpiece containing the composition is subsequently cleaned with a hot aqueous alkaline cleaner, thereby aiding in the easy and complete removal of the last traces of the bufling composition remaining after the workpiece has been bufied or polished.
Polishing and buffing compositions generally consist of a carrier lubricant, such :as various greases, oils or soaps (compounded to give the desired melting point or viscosity), in which there is dispersed one or more abrasive materials. When a metal workpiece is bufied or polished with these compositions, the residual buffing compound frequently becomes lodged or impacted in the recessed areas, fine lines, scratches or holes in the workpiece, and is quite difficult to remove even when the workpiece is subsequently submerged or scoured with an aqueous alkaline cleaning solution. Oftentimes, the residual bufling composition adheres to the metal surface so tenaciously that even fiat surfaces are difficult to clean. Treatment of the polished or buffed metal workpiece with a hot aqueous alkaline cleaning solution is almost always necessary to remove the last traces of the buffing compositions, especially if the polished or bufled workpiece is to be plated. Failure to remove the last traces of such buffing composition from the workpiece invariably leads to imperfect plating.
Using non-aqueous and aqueous bufling compositions both of which comprise a carrier lubricant in which there is dispersed a major amount of an inorganic abrasive, I have cfiound that by incorporating a minor amount of either aluminum powder or zinc powder in this butting composition, it is possible to prepare an improved buffing composition within which sufficient hydrogen gas may be generated in situ when a metal workpiece containing the composition is subsequently cleaned with hot aqueous alkaline cleaner, thereby aiding in the easy and complete removal of the last traces of bufling composition remaining after the workpiece has been buffed or polished. Based on this discovery, the invention provides an improved b-ufling composition comprising a carrier lubricant in which there is dispersed a major amount of an inorganic abrasive and a minor amount of metallic powder selected from the group consisting of aluminum and zinc.
In general, only relatively minor amounts of either aluminum or zinc powder (or both) are required in the bufling composition to aid in the removal of the last traces of the composition when the workpiece is subsequently cleaned with an aqueous alkaline cleaning solution. Excellent results have been obtained by using from about /2 to about 2 percent by weight of the metallic powder (preferably in the [form of flakes) in the buffing composition, although .for most purposes concentration of the metallic powder in the range from about to about 1 percent by weight of the composition will suflice.
After the metal workpiece has been bufied and polished with a bufiing composition containing either aluminum or zinc powder in accordance with the invention, it may be cleaned with an aqueous alkaline cleaning solution. These cleaning solutions are usually prepared by dissolving one or more strong alkalies in water, and are generally employed at elevated temperatures. The minor amount of aluminum or zinc powder in the trace amount of bufling composition which remains on'the surface of the buffed or polished metal workpiece reacts violently with the hot aqueous alkaline cleaning solution to liberate gaseous hydrogen, which, in turn, causes the adhering bufling and polishing composition to separate from the metal surface. Particularly good results are obtained if the buffed workpiece containing the residual buffing composition is electrolytically cleaned in the aqueous alkaline cleaning solution by making the metal workpiece one of the electrodes in a direct current circuit. Under these conditions, the evolution of gaseous hydrogen on the metal surface is even more effective. This gaseous hydrogen functions as a scourer of the remaining traces of bufling composition adhering to the workpiece.
The following examples are illustrative of the various non-aqueous and aqueous bufiing and polishing compositions which may be prepared in accordance with the invention: v
Example I A non-aqueous bufling composition was prepared by uniformly blending 12.24 percent by weight of stearic acid, 10.70 percent by weight of saturated fatty acids (Hydrofol Glyceride No. 42), 1.05 percent by weight of wood rosin, 3.43 percent by weight of tallow oil, 1.09 percent by weight of No. 9 oil, 70.49 percent by weight of No. 6 lime, and 1 percent by weight of aluminum powder. This buffing composition is especially suitable for use as a nickel coloring compound, and may be easily and completely removed from the metal workpiece with an aqueous alkaline cleaning solution.
Example II A non-aqueous bufling composition was prepared by uniformly blending 18.85 percent by weight of saturated fatty acids (Hydrofol Acids B.G.), 3.19 percent by weight of tallow, 9.57 by weight of petrolatum, 18.05 percent by weight of No. 54 silica, 49.34 percent by weight of Rose Tripoli (once ground) and 1 percent by weight of aluminum powder. This composition is especially suitable for use in the cutting of non-ferrous metals, and may be easily and completely removed from the metal workpiece with an aqueous alkaline cleaning solution.
Example III A non-aqueous bufling composition suitable for use as a steel coloring compound was prepared by uniformly blending 18.75 percent by weight of stearic acid, 3.75 percent by weight of oleo stearine, 2.5 percent by weight of paraffin wax, 74 percent by Weight of unfused alumina, and 1 percent by Weight of aluminum powder. This composition is also easily and completely removed from a metal workpiece buffed with the composition merely by using an aqueous alkaline cleaning solution.
Example IV An aqueous buffing composition was prepared by emulsifying 5.5 parts by weight 0t saturated fatty acids, 1.5 parts by weight of triethanolamine, 0.9 part by weight of a surfactant (Triton X400), 0.1 part by weight of a preservative, 3 parts by weight of petrolatum, 3 parts by weight of tallow, and 5 parts by weight of paraflin oil in 38.5 parts by weight of water. To this emulsion was then added 32 parts by weight of Rose Tripoli (once ground), 9.5 parts by weight of amorphous silica, and 1 part by weight of aluminum powder. The resultant aqueous 3 buffing composition is especially suitable for use as a cutting compound, and may be easily and completely removed from the metal workpiece with an aqueous alkaline cleaning solution.
Example V An aqueous :bufiing composition suitable for use as a coloring compound was prepared by emulsifying 7 parts by weight of saturated fatty acids, 2 par-ts by weight of triethanolamine, 0.4 part by weight of a surfactant (Triton X-100), 0.1 part by weight of a preservative, 1 part by weight of paraflin oil, 1 part by weight oleo stearin, 10 parts by weight of amorphous silica, 31 parts by weight of aluminum oxide, and 1 part by weight of aluminum powder in 46.5 parts by weight of water. The resultant buffing composition is easily and completely removed from a metal workpiece buffed with the compound merely by using a minor amount (from about /2 to about 2 Although each of the foregoing examples of the invention show the use of aluminum powder in the buffing composition, equally satisfactory results may be obtained by using a minor amount (from about /2 to about 2 percent by weight) of zinc powder in the bufling composition. Consequently, the invention is applicable to any bufiiing composition comprising a carrier lubricant in which there is dispersed a major amount of an inorganic abrasive and a minor amount of either aluminum powder or zinc powder.
