Title
(EN) CATIONIC SPREADING EMULSION
(FR) EMULSION CATIONIQUE DE REPANDAGE
Abstract
(EN) The present invention relates to the field of emulsions of hydrocarbon binders known as "spreading emulsions", in particular cationic emulsions of hydrocarbon binders. Such emulsions are useful in the preparation of surface wear coatings, bonding coatings, surface coatings of the fog seal type and paving stone joints. Using an anionic polymer in order to improve the immediate adhesiveness of a cationic emulsion of hydrocarbon binder to solid particles is described in particular.
(FR) La présente divulgation concerne le domaine des émulsions de liants hydrocarbonés dites « de répandage », en particulier des émulsions cationiques de liants hydrocarbonés. De telles émulsions sont utiles à la préparation des enduits superficiels d'usure, des couches d'accrochage, des couches de surface de type fog seal et des joints de pavés. L'utilisation d'un polymère anionique pour améliorer l'adhésivité immédiate d'une émulsion cationique de liant hydrocarboné à des particules solides est tout particulièrement décrite.
