Description
ALBERT C. I-IOLZAPFEL, GENE-W YOR Patented July ii, i922.
To all whom it may concern:
Be it known that T, ALBERT C. HOLZAPFEL, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Paint, of which the following is a specification.
This invention relates to processes of preparing paint, and more particularly to a method of treating paints formed of stearine pitch and other residual pitches to remove objectionable odor therefrom.
The present invention relates particularly to improvements in surface coating compositions wherein a residual pitch, such as stearine pitch, forms a substantial part of the mixture. Such paints are disclosed in my prior Patent No. 1,379,019, granted May 24, 1921.
Paints of the character described in my prior patent contain considerable quantities of tar distillatcs which have the characteristic odor objected to by many people and in the present invention I provide a deodorizer which has the capacity to disguise or hide the odor of tar oil.
I have found that small quantity of acetone or certain acetates, such as butyl or amyl acetate, when added to varnishes or paints in which stearine pitch or other residual pitch is a substantial ingredient will efiectually destroy the characteristic odor of tar present. The acetone or acetate may be added in any suitable proportions but I have found that the addition of from one to five per cent of such materials will effectually destroy the tar odor objected to by some people.
In a typical embodiment of the invention, a paint such as that disclosed in the prior patent referred to, may be prepared from a mixture of from 30 to 40 parts by weight of pitch derived from the treatment of oils and fats, and from to parts by weight of a hydrocarbon solvent. A small quantity of the residual pitch may be replaced by resin or gum, and from 10 to 20 parts of gum or resin may be employed if desired. The pitch, or pitch and gum, is thoroughly dis solved in the hydrocarbon solvent and suitable pigments may be added. In place of Serial No. 540,589.
the titanium oxide disclosed in my prior patent other pigments may be also employed.
The acetone or acetate employed to remove the odor of tar may be added to the mixture of pitch and solvent before the pigment is added, or may be added to the completed paint. VYhere the paint is manufactured sometime prior to its use, and the pigment is to be added when the paint is used, the acetone or acetate may be added at any desired time. The acetone or acetate may be added at the time the paint vehicle is prepared, or may be added before the addition of the pigment.
As stated, the proportions in which the material is added may be varied according to the nature of the particular paint with which it is to be employed, but I have found that the use of from one to five per cent of acetone, butyl acetate or amyl acetate is generally su'liicient to destroy the odor of tar present in such compositions either before or after the addition of the pigment.
While I have described in detail the preferred practice of my process, it is to be understood that the details of procedure, and proportions of ingredients may be widely varied, and that known chemical equivalents may be employed in place of the mate rials mentioned without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, I claim:
1. The process of deodorizing paints having residual pitch derived from the treatment of oils and fats as a material ingredient which comprises adding an acetyl compound thereto.
2. Theprocess of deodorizing paints having residual pitch derived from the treatment of oils and fats as a material ingredient which comprises adding acetone thereto.
3. The process of deodorizing paints having residual pitch derived from the treatment of oils and fats as a material ingredient which comprises adding from one to five per cent of an acetyl compound thereto.
4. The process of deodorizing paints having residual pitch derived from the treatment of oils and fats as a material ingredient which comprises adding from one to a hydrocarbon solvent, and a deodorizer,
five per cent of acetone thereto. said deodorizer comprising acetone. 10 5. A paint comprising a residual pitch de- In testimony whereof I affix my signature rived from the treatment of oils and fats a in presence of tWo' Witnesses. 5 hydrocarbon solvent, and a deodorizer, said ALBERT C. HOLZAPFEL.
deodorizer comprising an acetyl compound. Vitnesses:
6. A paint comprising a residual pitch WM. MARTIN, derived from the treatment of oils and fats, HELEN A. MCCANN.
