UNITED STATES JAMES H. GRAVELL, OF ELKINS PARK, PENNSYLVANIA.
MATERIAL AND PROCESS FOR PREVENTING METAL FROM RUSTING.
"No Drawing.
This invention relates to preventing material from rusting and one object of the invention is to provide an improved material and method for preventing iron and steel from rusting.
invention is to provide a basic admixture to which may be added various ingredients to produce special rust inhibitive effects.
I have discovered that a substantial and uniform coating of iron phosphate can be produced on iron and steel-by the applica tion of an admixture of phosphoric acid and a flotation oil, such as turpentine or. pine oil. The proportions of the ingredients may be varied to a great extent but the following formula will be found to produce satisfactory results:
Pineoil 40 gallons, phosphoric acid .6 pound. This admixture is rather viscous but I have v discovered that the admixture can be improved by the addition of an oil solvent such as a monohydric alcohol which boils at a higher temperature than ethyl alcohol, as an example, butyl alcohol produces the desired result and although the quantity used may be "varied,'the following formula shows it in sufficient amount:
Pine oil 40 gallons, phosphoric acid .6 pound, butyl alcohol 5 gallons.
These admixtures maybe applied to the metal by dipping or by surface brushing. At first a heavy liquid coating is produced but as time goes on, the .pine oil and, when it is used, the butyl alcohol evaporates and the phosphoric acid attacks the metal, so that finally a substantial and uniform coating of phosphate is formed onthe metal. This coating produced isv satisfactory to prevent the formation of rust when the metal is not exposed to the weather-but to. have the metal remain free from rust in the weather, I find the phos hate coating must be protected. To provi e this protecevaporating material which is normally liquid or will become liquid on solution in my admixture so that on the evaporation of the pine oil and, the butyl alcohol it will remain in the solid or liquid state to protect the phos phate coating. Such materials as heavy 'mineral oils or animal and vegetable drying oils or animal and vegetable nondrying oils or gums and rosins are suitable for my Another object of the tion, I incorporate in my admixture a noning in treating the Application filed January 20, 1923. Serial No. 614,043.
purpose. For instance a heavy mineral oil produces a liquid protective coating; linseed oil produces a dry elastic coating; shellac produces a hard coating. In the fob lowing formula I have selected heavy mineral oil: 7
Pine oil 40 gallons, phosphoric acid .6 pound, butyl alcohol 5 gallons, heavy mineral oil 20 gallons.
It often happens that the work to be processed has been pickled, soldered or handled to a great extent and has therefore 'LLCCHIILLL- lated obnoxious substances on the surface. When such metal is treated with the above admixtures, rust sometimes develops, due, I
believe, to the inability of the admixture to dissolve the obnoxious material and in order to facilitate this solution'I may add a solvent such as ethyl or methyl alcohol or denatured alcohol. Ethyl acetate, acetone, etc. may also be used but I prefer to use No. 44- denatured alcohol as shown by the following formula Pine oil 40 gallons, phosphoric .acid .6 pound, butyl alcohol 5 gallons, heavy .mineral oil 20 gallons, N0. 44 denatured alcohol 30 gallons.
The last described formula forms a rather thin consolute liquid which is easily applied by brushing, spraying or dipping and its app ication forms a most satisfactory means of preventing the rustin cold rolled sheet steel suc as automobile blqdies during storage or transit to the paint 5 0p, p
As my invention is a chemical one it will be evident to those skilled in the art that of fabricated chemical equivalents maybe substituted for the specific ingredients given in my formulas Without departing from the spirit of the in vention which is not limited as to mere mat-. ters of form or otherwise than as the prior art and the appended claims may require.-
I claim: Y 1. The process of developing a coating of phosphate on the surface of metal consist.-
metal with an admixture comprising phosphoric acid and a flotation oil.
2. The process of developing a coating of phosphate on metal consisting in treating the metal with an admixture comprising phosphoric acid and pine woil.
3. The process-of developing aicoating of phosphate on metal consisting in treating coating of phosphate on metal consisting in treating the metal with an admixture comprising phosphoric acid, pine oil, a 'nonevaporating mineral oil. and alcohol.
7. A material for preventing metal from 2 rusting consisting of an admixture comprising phosphoric acid and a flotation oil.
8. A material for preventing Inetal from rusting consisting of an admixture comprising'phosphoric acid and pine oil.
9. A material for preventing metalfrom rusting consisting of an admixture com rising phosphoric acid, pine oil and buty alco 0 10. A material for preventing metal from rusting consisting of an admixture comprising phosphoric acid, pine oil, butyl alcohol and a material soluble in the adnnxture an capable of protecting a phosphate coating.
11. A material for preventing metal from rusting consisting of an admixture comprising phosphoric acid, pine oil, alcohol and mineral oil.
12. A material for preventing metal from rusting consisting of an admixture comprising phosphoric acid, pine oil, butyl alcohol and mineral oil.
13. A consolute fluid'for preventing metal from rusting being the product of mixing together phosphoric acid, flotation oil, mineral oil, and alcohol.
14. A material for preventing metal from rusting consisting of an admixture comprising phosphoric acid, pine oil, butyl alcohol, mineral oil, and ethyl alcohol.
