A process for preparing an aqueous emulsion of oil and / or rubber and / or a well-shielded (poly) isocyanate resin. And the resulting emulsion (METHOD FOR PREPARING AQUEOUS EMULSIONS OF OILS AND / OR GUMS AND / OR PREFERABLY MASKED (POLY) ISOCYANATE RESINS, AND RESULTING EMULSIONS)

摘要

(A), and (2) water, at least one surfactant (B) and optionally at least one water-soluble intermediate polymer (C) having a viscosity of at least 3 Pa s or a roughness of 200 or more and a well shielded (poly) isocyanate phase, (Poly) isocyanate resin is prepared by kneading a mixture composed of a water-soluble polyisocyanate (A) and an aqueous phase composed of a polyisocyanate (A) (B) and optionally (C) so as not to be lower than that of the water-in-oil emulsion, and the above-mentioned kneading is carried out for a sufficient time with sufficient shear force to obtain an oil-in-water emulsion having a particle size of 0.1 to 5 m , The medium is optionally diluted by water.
