Lauren sTATes SOLUTION FOR TREATING THE SURFAGE OF STEEL OR IRON FOR THE APPLICfli- TION (3F PAINT- Charles a. Cook, Jan, West nardordpconn.
No Drawing: Application May 16, 1935, Serial No. 21,913
6 Claims. (Cl. 148-65) This invention relates to a rust-proofing process and formula whichwill'efiectively produce or cause to be produced on iron or steel or their alloys a protective rust-resisting coating which is a satisfactory finish coat in itself when oiled, or provides an adherent base for paint, enamel, or lacquer.
In the use of my improved solution herein set out I have demonstrated to my entire satisfaction 10 that a treatment of a surface of steel or iron with my improved solution will enable paint, lacquer, japan, or other coloring or coating matter to be applied in an effective manner and that such coating will be retained until it is worn away as the result of natural effects. In other words, the coating will adhere so tenaciously as to prevent its being peeled or flaked off.
I am disclosing herein the ingredients comprising formulas for my improved solution and the 21 proportions of such ingredients and the method of their application, these ingredients, the proportionsthereof and method of application, having produced results entirely to my satisfaction It will be understood, however, that the propor- 25 tions may be deviated from to some slight extent and yetproduce effective results, but as above noted, the formulas set out have-been most satisfactory.
My improved solution comprises oxalic acid combined with nitric acid and a nitrate, either or both of the latter. In the treatment of a surface of steel or iron such surface is first thoroughly cleaned in any desired manner, gasolene or other similar substance having been found to work sat- 3ii isfactorily. After such surface has been cleaned and dried it is treated with an application of my improved solution. This may be applied by dipping the article into the solution and then allowing the solution to drain from the article. The 40 article is then rinsed in water to remove any surplus portions of the ingredients and such article may then be subjected to any desired degree of heat, as in an oven, for the purpose of drying it.
As above intimated I contemplate a combination of various ingredients hereinbefore mentioned. As an example, oxalic acid and nitric acid may be employed tocomprise the solution, or oxalic acid and a nitrate may be employed, or the three ingredients oxalic acid, nitric acid and a nitrate may l e/combined in the solution. The
ingredients and the proportions thereof which I have found to effect most satisfactory results are as follows:
room temperature of about the treatment To 1 gal. water Oxalic acid "oz-.. 2
Nitric acid (36 Baum) c.c 20
To 1 gal. water ()xalic acid "oz-.. 2 Nickel nitrate oz.. 3 4 To 1 gal. water Oxalic acid oz v 2 Nitric acid (36 Baum) c. c... 10 f Nickel nitrate oz Va 20 has been completed in about three minutes and with ahigher temperature the treatment may be. completed in less time, I
I claim:
1. The process of producing a rust-resisting coating on iron or steel articles by subjecting them to the action of oxalic acid and nitric acid in solution and in the proportions of 4 to 12 parts of oxalic acid to 1 to 3 parts of nitric acid.
2. The process of producing a rust-resisting coating on iron or steel articles by subjecting their surfaces to the action of oxalic acid, nitric acid, and a nitrate in solution and in the proportions of 4 to 12 parts of oxalic acid to 1 to 3 parts of nitric acid.
3. A solution comprising oxalic acid and nitric acid and in the proportions of 4 to 12 parts of oxalic acid to 1 to 3 parts of nitric acid.
4;. A solution comprising oxalic acid, a nitrate, and nitric acid and in the proportions of ito 12 parts of oxalic acidto 1 to 3 parts of nitric acid.
5. A solution consisting of oxalic acid dihydrate and nitric acid (36 Baum) in the proportion by weight of 4 parts oxalic acid dihydrate to 1 part nitric acid (36 Baum) in 1 gallon of Water. 45
6. A solution consisting of oxalic acid dihydrate, a nitrate, and nitric acid (36 Baum) in the proportion by weight of 8 parts oxalic acid dihydrate, 1 part nitrate and 1 part nitric acid (36 Baum) in 1 gallon of water.
