No Drawing. Original No. 2,046,305, dated June 30, 1936, Serial No. 71 4,267, March 6, 1934. Appllcation for reissue June29, 1938, Serial No.
n This invention relates to a new waterproofing composition for waterproofing fabrics and other materials and includes the new composition and the method of making it, as well as the method of waterproofing therewith. v
In the waterproofing of fabrics, etc. with an insoluble soap, it has been proposed to use two successive treating solutions, one of which is a solution of a water solublesoap and the other a solution of a salt which will react with the water soluble soap to form an insoluble soap. This method of treatment requires two successive treatments and there is liable to be an excess of one of the reagents to-be subsequently removed.
The present invention provides an improved aqueous composition which is used in a single treatment, with a single bath, followed by heating the treated fabric, etc. to bring about changes M or reactions in the composition and the effective waterproofing of the material.
The invention will be illustrated by the follow- I v -ing example:
Equal parts by weight of diglyco stearate and paraflin wax are melted together at a temperature of about 205 F. and uniformly mixed and blended, and boiling water-is added thereto while at such temperature and with rapid agitation to efl'ect a uniform distribution of the materials 80 with the water. The water is added in the proportions of about fifteen gallons to about nine and three-quarters pounds of the melted mixture; The rapid agitation is continued until the hot liquid mixture is cool and there is then I I added about fifteen gallons of a solution of aluminum sulfate containing about seven and onehalf pounds of aluminum sulfate. Reaction does not take place between the aluminum sulfate and the diglyco stearate at low temperatures and 0 this emulsion can be further diluted, for exampie. with two to four parts of water added to one part of the emulsion, before it is used for water- 10 class (01. 91-68) diglyco stearate with the aluminum sulfate, and it increases the permanence of the waterproofing effect.
Instead of paraffin. wax, other suitable waxes can be used, such as o'zocerite, beeswax, carnauba 6 wax, montan wax, etc., but I consider paraflln wax more advantageous, for use in the new composition.
Instead of using dig lyco stearate, other diglyco 2 fatty acid esters can be used, such as diglyco l0 oleate, diglyco palmitate, or mixtures or mixed. esters, etc. The products used in accordance with this invention are those sold as diglycol stearate, diglycol oleate, etc.
Instead of using aluminum sulfate, other metal 15 salts can be used which form insoluble soaps such as lead acetate, aluminum acetate, zinc chloride,
etc. Aluminum acetate is; a particularly advantageous salt to use and it can readily be prepared by the reaction of solutions containing approximately equal amountsof aluminum sulfate and lead acetate. Aluminum acetate itself has water-,
proofing properties, particularly after it has been subjected to heating, and this action may supplement any formation of insoluble aluminum soap-where an excess of the aluminum acetate is used, or where only part of the aluminum acetate used reacts to form the insoluble aluminum soap. In making the new composition, apparatus 0 should be used which is resistant to the chemical action of the ingredients, for example, Monel metal apparatus or earthenware apparatus.
In using the new composition, a single bath and a single treatment of the fabric or other material is suflicient.- The aqueous emulsion is readily absorbed by the fabric or other material, and, when heated to a suitable temperature, undergoes reaction with resulting effective waterproofing of the fabric. I consider a composition 40 in which diglyco stearate, paraifln and a soluble aluminum salt, such as aluminum acetate, are used, particularly advantageous since the combination of aluminum stearate, formed by the reaction, together with paramn in intimate combination, gives excellent resistance against washing and dry cleaning of the treated fabric.
In the continuous waterproofing of fabric, the fabric is passed continuously through a bath of the composition and then over a heated roll or through a heated chamber to heat the fabric and the composition to bring about the desired rewashed to remove soluble compounds, where this is desired, and can then be dried in a continuous manner by passing over a drying roll.
I claim:
1. A waterproofing composition comprising an aqueous emulsion of a diglyco ester of a higher fatty acid and a soluble salt of a metal which reacts with a higher fatty acid to form an insoluble soap.
2. A waterproofing composition comprising a wax and a diglyco ester of a higher fatty acid, intimately blended together and suspended in a finely divided state in water, which water contains dissolved therein a salt of a metal forming an insoluble soap.
3. A Waterproofing composition comprising diglyco stearate, parafiin and a soluble salt of aluminum.
4. 'A waterproofing composition comprising 0' diglyco stearate, paraflin and aluminum acetate,
said composition being in the form of an aqueous emulsion.
5. The method of forming a waterproofing composition which comprises melting together a wax and a diglyco ester of a higher fatty acid,
forming an emulsion of said mixture with water and adding thereto a soluble salt of a metal forming an insoluble soap.
6. The method of forming a waterproofing composition which comprises melting together parafiin wax and diglyco -stearate, formingan emulsion with the resulting melted mixture and water and adding thereto a soluble salt of alummum. x
'7. The method of waterproofingfabric, and
other materials which comprises applying thereto an aqueous emulsion containing paramn wax and diglyco stearate intimately combined and distributed therein and also containing a soluble salt of aluminum, and heating the resulting fabric to bring about reaction between the aluminum salt and the diglyco stearate to form aluminum stearate.
a process which comprises applying thereto an aqueous emulsion containing a wax, a diglyco ester of a higher fatty acid and a soluble metal salt forming an insoluble soap, and heating the .thus treated material to bring about reaction between the metal salt and the diglyco ester to form an insoluble soap.
10. Fabric and other materials waterproofed 'by a process which comprises applying thereto an aqueous emulsion containing paraflin wax, diglyco stearate and a soluble metal salt forming an insoluble soap, and heating the thus treated material to bring about reaction between the metal salt and the diglyco stearate to form an insoluble soap.
