Patented Nov. 18, 1941 WATERPROOFING COMPOSITION AND PROCESS OF PRODUCING SAME Joseph P. Nothum, Elizabeth, N. J., and Francis J. Licata, New York, N. Y., assignors to National Oil Products Company, Harrison, N. J., a corporation of New Jersey No Drawing. Application June 4, 1938,

13 Claims.
The invention relates in general to waterproofing compositions, and in particular to waterproofing compositions of the water-insoluble soap type and to correlated improvements in the process of producing such compositions.
The excellent waterproofing properties of the water-insoluble soaps, such as aluminum stearate, calcium oleate, etc. has long been recognized. Such soaps are preferably dissolved or dispersed in a suitable organic solvent, the resulting solution being applied to the desired surface in any suitable manner. W'hile varying quantities of the water-insoluble soaps may be dispersed in hydrocarbon and other solvents with the aid of heat, it is a known fact that such solvents will tolerate the presence of not more than about 2 or 3% soap and yet remain fluid at atmospheric temperatures. When more than 2 or 3% of a water-insoluble soap is dispersed in a solvent, heat is necessary, and on cooling the mass solidifies to form a gel. In view thereof, the concentration of the soap in solution has been limited to ensure a fluid product which is necessary to effect proper impregnation and/or coating.
In an attempt to increase the concentration of water-insoluble soap solutions in organic solvents, various peptizing or fiuidifying agents have been suggested, such as acetic acid and the ethanolamines. In view of the acidity and corrosive character and for other reasons, the use of acetic acid has been found to be highly objectionable. While the ethanolamines have been used with satisfactory results, these agents leave room for improvement.
It has been found that the concentration of water-insoluble soaps in solvent solutions or dispersions of the same, may be greatly increased by the use of oil-soluble mineral oil sulfonates known generally as mahogany soaps. Fluid compositions of this character are disclosed and claimed in copending application, Serial No. 117,018, filed December 21, 1936. The present invention is relevant to-the subject matter of the aforementioned application and has for its main objective the provision of a solid water-insoluble soap composition adapted to be dissolved directly in varying quantities in an organic solvent to produce a fluid concentrated soap-solvent dispersion.
According to the invention there is provided a solid composition comprising a water-insoluble soap and mahogany soaps. This product is preferably produced by admixing mahogany soaps with an aqueous solution of a water-soluble soap, adding a water-soluble salt of a polyvalent metal to produce the corresponding insoluble soap and drying the composition.
The invention accordingly comprises the several steps and the relation of one or more of such steps with respect to each of the others, and the composition possessing the features, properties and the relation of constituents, which are exemplifled in the following detailed disclosure, and the scope of the invention will be indicated in the claims.
In preparing the novel composition of the invention, any suitable water-soluble soap of a higher fatty acid may be employed, such for example, as sodium, potassium, ammonium, etc., soaps of stearic, palmitic, oleic, naphthenicflinoleic, etc. acids, hydrogenated fish oils and the like. In view of the similar properties and characteristics of the naphthenic acids, they are included herein under the generic expression of fatty acids or higher fatty acids, and salts thereof are included in the expression soap. To an aqueous solution or dispersion of any one or more of the foregoing or other suitable water-soluble soaps, there is added with stirring a quantity of mahogany soaps. A Water-soluble salt of a polyvalent metal, such as aluminum sulfate, calcium chloride or the like, is then added to convert the water-soluble soap into the corresponding water-insoluble soap. The precipitated mass which includes the water-insoluble soap and mahogany soaps is separated from the aqueousmedium and dried, after which the dried product may be reduced to a powdered or granular mass.
The resulting solid product which comprises an intimate mixture of the water-insoluble soap and mahogany soaps is highly soluble in the usual organic solvent, normally used for dissolving water-insoluble soaps, such as aliphatic or aromatic hydrocarbons, chlorinated hydrocarbons or other suitable solvents which specifically include, inter alia, toluol, benzol, xylol, petroleum spirits,
gasoline, terpenes, carbon tetrachloride, trichlor-,
ethane, etc. or any suitable mixture of these or other solvents. Solutions characterized by being free flowing at atmospheric temperatures and containing up to 40% or more water-insoluble soap may be produced by merely dissolving the solid composition of the invention in a suitable solvent.
The quantity of mahogany soaps used may be varied to produce the desired characteristics in the solid product and/or in the solution to be produced therefrom, the preferred range, however, lying between 1.% to 20% based on the dry weight of the insoluble soap. The solid composition of the invention may also have included therein other solid constituents, such as plasticizers, softeners, dyes, pigments or other coloring matter, etc.
For a fuller understanding of the nature and objects of the invention, reference should be had to the following examples which are given-merely to illustrate further the invention and are not to be construed in a limiting sense:
as new and desire I 7 Example I V Twentyparts by weight of mahogany soaps are added to 250 parts by weight of a 40% aquee ous solution of sodium stearate with stirring and the mixture diluted to about a 5% concentration after which it is precipitated with alum at about pared by merely dissolving the same in a suitable organic solvent such as toluol. e Exam le II T f To 250 parts by weight of a 40% aqueous so lution of a water-soluble soap of a hydrogenated fish oil'there is added. 15 parts by weight of ma-F hoganysoaps and a small amount of an alkali.
This mass is, diluted and precipitated with alum 1 at about 65 C. The precipitate is then filtered, washed and dried. lhis product is likewise adapted to be dissolved directly in a solventto produce a concentrated solution.
While it is preferred to add the mahogany soaps to the water-soluble soap solution before precipitation due to the fact that during precipii 'tation the mahogany soaps appear to'become.
more uniformly occluded in the water-insoluble operation if desired;
Since certain changes in carrying out the above process and certain modifications in the compo sition which embody the invention may be made without departing from its scope, it is intended that all mattercontained in the above description shall be interpretedas illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention] herein de-.
scribed and all statements of the scope of the invention, which as a matter of language might be said to falltherebetween; and that they are intended to be inclusive in scope and not exclusive,
in that if desired, other materials may be added to my novel composition of matter herein claimed without departing from the spirit of the invention. Particularly it is to be understood that in said claims, ingredients or components recited in the singular "are intended to include compatible. mixtures of said ingredients wherever the sense permits.
