Fremgangsmåde til fremstilling af vandige emulsioner af olier og/eller gummier og/eller harpikser på basis af (poly)isocyanater, der med fordel er maskerede, og opnåede emulsioner |
摘要 |
A method for preparing aqueous emulsions of oils, gums or preferably masked (poly)isocyanate resins by kneading a mixture consisting of (1) a preferably masked (poly)isocyanate phase (A) with a viscosity of at least 3 Pa.s or a consistency of at least 200, and (2) an aqueous phase consisting of water, at least one surfactant (B) and optionally at least one water-soluble thickening polymer (C), the relative amounts water, (B) and optionally (C) being such that said aqueous phase has a viscosity or consistency preferably no lower than that of the preferably masked (poly)isocyante phase (A), and said kneading being performed for a sufficient time and with sufficient shear to give an oil-in-water emulsion with a particle size of 0.1-5 mum, and optionally by diluting the medium with water. |
