| titleOfInvention | Improvements in or relating to the production of resin emulsions |
| abstract | Aqueous emulsions of synthetic resins are made by dissolving or dispersing the resin in, or diluting it with a volatile organic solvent, emulsifying the product in water in the presence of bentonite or like clay and a soap such as sodium oleate, and distilling off the solvent. Phenol-aldehyde, urea-aldehyde, and alkyd resins, and particularly resins made as disclosed in Specifications 267,736, 293,453, and 324,025, [all in Class 2 (iii)], are specified. The emulsifying agents are in general together equivalent to from 1--10 per cent of the water. In an example, a resin obtained from phenol, tung oil, hexamethylenetetramine, and phosphoric acid is taken up in benzene, added with agitation to water containing equal weights of sodium oleate and bentonite, and the emulsion boiled under atmospheric pressure or vacuum, for example by passage of steam, the benzene distilling with some of the water. Other solvents such as toluene, ethyl acetate, and volatile alcohols and ketones, e.g. acetone, may replace benzene. The resulting emulsion can be used for coating materials such as cloth and paper, and for impregnating brake linings. The Specification as open to inspection under Sect. 91 includes the use of any two or more emulsifying agents. Casein-ammonia and gum arabic are also specified. This subject-matter does not appear in the Specification as accepted.ALSO:Aqueous emulsions of synthetic resins are made by dissolving or dispersing the resin in or diluting it with a volatile organic solvent, emulsifying the product in water in the presence of bentonite or like clay and a soap such as sodium oleate, and distilling off the solvent.
