To all whom it may concern. Be it known that 1, JAMES H.:GRAVELL, a-
a new and useful Improvement in Rust-Removing Compositions for Metals,-of which the following is a specification.
This invention relates to rust removing and preventing compounds generally, and especially to those compounds which are used for preparing metal for painting.
{One object of the invention is to provide a compound that will efficiently remove rust and will neutralize or destroy those agencies 'W which cause rust, such as hand marks, acid runs and soldering solutions; Another object of the invention is to provide a material which will remain wet or liquid after being placed on the surface; to becle'aned for sufiicient time for enabling it to complete its work. I y v e I It is now well known that acids are very satisfactory for removing rust and. that phosphoric acid, owing to the easeof securing it commercially, is especially useful for that purpose.
To use these acids for cleaning metal, they are diluted with a solvent to the. proper strength and are applied directly to the surface to. be cleaned .by dipping, spraying or brushing.
In practice it is found thatthe solvent evaporates or that the compound dries long before the chemical activity of the acid is exhausted with the result that'all cleaning action stops and repeated applications of the diluted: acid must be resorted to in order to properly clean the surface.
i I have discoveredthat the addition of sodium in'proper quantities to the acid-sold.
tion causes it. to remain'li uid or wet for a substantially longer peri sothatasingle application of the acid solution is m many cases all that is required.
In order make my cleaner I may use :1 7
, 85% phosphoric acid 1 Metallic sodiume 4 This may betermed myprepared acid.
Application filed; May 9,
192 semi no. 559,598.
To inake upacleaning solution I may use:
Gallona' Prepared acid; 21 Water '55 This solution works very satisfactorily on work that is free from oil, but is not eflec t1ve where oil-is present. In order to make the material eifective on'an oily surface I add an ingredient adapted to lower the sur-v so face tension of the compound, such as alcohol, acetone or ethyl acetate, as follows:
. e Gallons.
Prepared acid 21 ater I Alcohol, ethyl or itsequivalent 19 The oil removing properties. of the com-' pound may be further improved by the addition of fusel oil or any of the components of fusel oil, such as butyl alcohol, as follows:
' Gallons. Prepared acid i 21 Water e i 55 Alcohol, ethyl or its equivalent- 19 Butyl alcohol 5 salt are insoluble in water and the term sodium includes any metal which dissolved in the acid will not-be precipitated by the addition of alcohol and which has the propertyof keeping. the composition liquid orwet. d
It'is within thesco e of the invention to produce my prepare acid bythe action of. an acid on material containin sodiumso that the sodium phosphate e automatically producedin association with the metal etching acid, in other fwords,;sodium content m of the finished prepared acid may be taken care of in the manufacturing of the mono-sodium phosphate, substantially as clehasic achl. scribed.
ll claim: p 3. A cleaning agent for metals comprising 1, A cleaning agent for metals comprising free phosphoric acid, water, ethyl alcohol,
s free phosphoric acid, water and mono-sobutylalcohol and mono-sodium phosphate,
diam phosphate, substantially as described. substantially as described. a
