    摘要: A process is provided for preparing in aqueous emulsion, a bitumen/polymer binder with a continuous three-dimensional polymeric structure. The process comprises:a) forming a reaction mixture in an emulsion formation zone by feeding to the zone(i) a bitumen-polymer component comprised of a bitumen containing 0.5% to 15%, by weight of the bitumen, of a sulphur-crosslinkable elastomeric polymer, the bitumen/polymer component being in the form of a melt viscosity of not more than 2 Pa.s at the melt temperature,(ii) an aqueous phase containing an effective quantity of an emulsifying system, and(iii) a crosslinking system donating sulphur in a quantity such as to provide 0.5 to 20% by weight of sulphur relative to the weight of the elastomeric polymer contributed by the bitumen/polymer component, andb) maintaining the reaction mixture in the emulsion formation zone at an appropriate temperature until an aqueous emulsion of bitumen/polymer binder is obtained, in which the polymer of the binder is at least partially crosslinked to a three-dimensional structure.The bitumen/polymer binder is useful for coating road surfaces.

    摘要: This invention provides cationic emulsions of bituminous binders of the bitumen/polymer type, formed by a dispersion of an organic phase of the binder in an aqueous phase containing a cationic nitrogenous emulsifier and a mineral or organic acid, the acid being in appropriate quantity so that the pH of the aqueous phase is comprised between 3 and 9. The aqueous phase also contains an agent consisting of at least one water-soluble sequestering salt of phosphonic acid, particularly a salt of alkaline metal or of amine of hydroxyalkyl-1,1-diphosphonic acid, and optionally a water-soluble thickening agent. To obtain the emulsions, which are usable for road applications, the emulsifying agent, the sequestering agent and optionally the thickening agent may be used in the form of a premixture containing the agents and called cationic emulsifying system.
