METHOD FOR PREPARING IN AN AQUEOUS EMULSION A BITUMEN/POLYMER BINDER WITH CONTINUOUS TRIDIMENSIONAL POLYMER STRUCTURE AND APPLICATION OF SUCH BINDER FOR COATINGS OR COVERINGS

摘要

this leads to a 2065727 9201752 pctabs00110 formation zone of asphalt emulsion (i) a cross linkable polymer component and sulfur.which is in the form of a molten mass with a temperature of between 100 and 230 - c during the summer - c during the summer and a viscosity of not more than 2).at that temperature.(ii) an aqueous phase containing an emulsifier system with temperature between 10 - c during the summer and - c during the summer, and (iii) a crosslinking system, sulfur donor in appropriate quantity.the weight ratio of the component with the aqueous phase from the polymer to 30: 70 to 85: 15, and the mixture thus formed is in the area of the formation of the emulsion.at a temperature of between 50 and 160 - c during the summer - c during the summer, so as to obtain a bitumen emulsion polymer binder in which the polymer of the binder is cross-linked in a three-dimensional structure.the emulsion obtained is suitable for the realization of the road surfaces, coated with sealant or coating.
