  • Patent number: 4190568
    Abstract: A mineral stabilized resin emulsion comprising a low to zero acid number hydrocarbon resin modified with an organic acid to the extent necessary for emulsification, a mineral stabilizer and a complexing agent such as an inorganic acid, a polyvalent metal ion or ammonium ion compound. A method for producing the mineral stabilized resin emulsion comprises subdividing the acid modified hydrocarbon resin by a combination of melting, mechanical and chemical dispersion in an aqueous medium and stabilizing the resultant dispersion by the addition of the complexing agent compatible with the resin and a hyrophillic mineral strabilizer such as bentonite clay. Accordingly, the hydrophillic mineral stabilizer orients to the aqueous portion of the emulsion and is coupled thereto by the complexing agent. The coupling action of the complexing agent is generally effected by a polyvalent metal ion such as chromium, iron, magnesium or aluminum, however, other ions such as ammonium ions are suitable for this purpose.
