摘要

Process for the preparation of slow break cationic bituminous emulsions, for coating road floors, juice zones, industrial floors and the like, characterized in that it comprises stirring homogenization an organic phase and an acidic aqueous phase, essentially the first constituted by to 65% of a hydrocarbon binder, preferably ordinary or possibly harder penetrability asphalt and 0.6 to 1.4 preferably 0.6 to 1% of the emulsifier agent, essentially constituted by at least one polyaminoimidazoline of the general formula ** formula ** where r is a hydrocarbon radical, saturated or unsaturated, with 8 to 22 carbon atoms and x is between 3 and 6 in which the polyaminoimidaline fraction in which x has the value 3 represents at least 20% of the polymer, and in which embodiment, which is conducted at room temperature, the aqueous phase is dosed, carrying acid in solution, preferably hydrochloric acid, in such a proportion that a ph between 3 and 3.5 controlled during the preparation is reached in the mass in order to raise the acidity in low acid asphaltic components.
