Definitions
- This invention relates to the treatment of metal surfaces, especially of fabricated steel, whereby said surfaces are freed from fore1 substancessuch as oil, grease and the li e, 6 along with rust, and all rust stimulants, and are left in a condition to receive and retain a protective coating of paint, enamel or the like.
- This a plication is a division of m W application Serial No. 8,538,filed paragraph 11, H 1925, and is especially concerned with a material or composition for use in the treatment of metal surfaces as just set forth.
- the present usual method of preparing such surfaces for painting is either y the use of a sand blast, or by treating the metal with suitable liquid acid of various kinds usually containing alcohol as an oil displacer or solvent. Sometimes the two are used in conjunction.
- suitable liquid acid usually containing alcohol as an oil displacer or solvent.
- the sand blast method is very injurious to the workmen who apply the treatment.
- the liquid acid treatment involves mechanical difficulties in securing the even distribution of the reagent upon the surface to be treated.
- the thin liquid condition of the acid solution requires many applications to keep the metal wet during the sanding operation, and in addition to the above the acid solution penetrates all cracks and crevices from some of which it is impossible to completely remove it, and from which the acid later works out due to the action of the heat required to set the paint used.
- My present invention involves the use of an inert aqueous paste in which are incorporated the rust and oil removing agents.
- This paste com osition may be sprayed or otherwise applied to the surface in a continuous layer or coating, which thus remains upon the surface, and which before drying absorbs much of the dissolved rust and grease, and which after drying clings tenaciously to any softened rust or rease remaining on the sur- 65 face, so that w on in its dry condition it is brushed or flaked oif, the complete removal of these substances from the metal surface is effected, thus calling for much less, if any, subsequent abrasion of the surface than 1n the previously described recess.
- the aqueous paste ma e formed by add- 1n Water to any finely ivided inert mineral su stance, capable of producing the desired plastic mass.
- Various clays or similar substances may be employed, but I prefer to use cryolite, silica, alumina, powdered talc or fluor spar and the like.
- rust-removing agent I employ any of those acids which have'the capacity of readily dissolving, or rendering harmless to paint, the iron oxides, chlorides or iron salts liable ,to be found upon metal surfaces. Most of the mineral acids, and also oxalic, acetic, tartaric and citric acids have this 7 capacity. Phosphoric acid has long been used for this purpose.
- a mineral acid that forms water-soluble salts with iron may be employed singly or can be used in conjunction with organic acids capable of producing insoluble iron salts by double decomposition. For example tannic acid with sulphuric acid in the presence of iron results in the formation of insoluble iron tannate.
- I may employ any of the alcohols, ketones or esters which possess the capacity of dissolving or displacing the oil or grease.
- Various aromatic hydocarbons also possessasimilar capacity.
- aqueous paste may remain a homogeneous mass and maintain the finely divided material in suspension
- the proportions given above may be varied provided there be used a sufiicicnt amount of the reagentsto act upon the rust and grease, and provided also the materials be so pro )ortioned as to produce an aqueous paste 0 the proper consistency to permit of easy application to the surface in an even layer, whlch will not run down a vertical surface, and
- the suspending agent (ferric phosphate) keeps the composition homogeneous when first applied, and prevents it from running or sagging,notwithstanding the rather large proportion of liquid organic oil re- 'mover.
- the reagents have softened or dissolved the rust, oil and grease upon the surface to which they are applied, and the finely divided inert material will be found to have absorbed into its subare softened and are tenaciously adherent to the dried paste when rubbed off, so that the metal surface is left in the desired clean confbrric phosphate is fully dissolved;
- the finely divided material erforms a combination of useful mechanica functions. It actsas the vehicle for securing the even application of the reagents to the surface of the metal and their maintenance in proper contact long enough for them to perform their function. It further acts as an absorbent taking to itself the dissolved materials which are to be removed. Further it clings with tenacity to softened, but unabsorbed articles of rust or grease, and when dry is riable and flaky, easily brushed off, carrying With it these adherent particles of foreign substances which it is desired to remove.
- the finely divided substance or vehicle may be any finely divided mineral material which is not acted upon chemically by the other substances employed when mixed with them to form the paste, and is thus inert or compatible with respect to the other in redients.
- a coating and drying composition'for removing foreign substances such as rust and oil from metal surfaces preparatory to painting comprising rust and oil solvents in combination with a finely divided vehicle and a metallic salt whichcooperates with the oil solvent to maintain the finely divided material in suspension.
- a coating and drying composition for removing foreign substances such as rust and oil from metal surfaces preparator to painting comprising rust an oil 5.
- a coating and drying composition for removing foreign substances such as rust and oil from metal surfaces preparatory to painting comprising rust and oil solvents in combination with finely divided material formin with the foreign substances to be remove when applied and dried on a metal surface to be cleaned, a loose, friable coating.
