Title: Process for making pigmented acid emulsions of hydrocarbon binding agents
IPC: C08L95/00
Filed: 1963-02-14
Abstract: A pigmented emulsion is made by coating a pigment with a cationic soap and then incorporating the pigment into an aqueous acidic emulsion of a hydrocarbon binding agent or petroleum synthetic resin. Pigments may be white or coloured, e.g. an iron oxide, cadmium red, chrome yellow or titanium dioxide.  The hydrocarbon binding agent may be, e.g., bitumen, cut-back, road-oil or tar and the petroleum synthetic resin may be a petroleum resin, i.e. a thermoplastic polymer of petroleum distillates, olefins, or diolefins, with or without flux oil, or a natural or synthetic elastomer, e.g. of above monomers.  The cationic soaps are salts of water-soluble inorganic or organic acids, e.g. HCl, HCOOH, or CH3COOH, and primary, secondary or tertiary amines or polyamines, quaternary ammonium bases, amido-amines, or amines, polyamines, or amido-amines to which an alkene oxide has been added.  The product may be used for surfacing.ALSO:A pigmented emulsion is made by coating a pigment with a cationic soap and then incorporating the pigment into an aqueous acidic emulsion of a hydrocarbon binding agent or petroleum synthetic resin.
