DISPERSIONES DE POLIURETANO Y SU EMPLEO
Procedimiento para la obtención de dispersiones de poliuretano, pudiendo ser obtenidas las dispersiones de poliuretano si a) se prepara un prepolímero terminado en NCO a partir de macroloes de polioes iónicos o potencialmente iónicos y de poliisocionatos en exceso, b) este prepolímero se hace reacci...

| description | Procedimiento para la obtención de dispersiones de poliuretano, pudiendo ser obtenidas las dispersiones de poliuretano si a) se prepara un prepolímero terminado en NCO a partir de macroloes de polioes iónicos o potencialmente iónicos y de poliisocionatos en exceso, b) este prepolímero se hace reaccionar con compuestos que presenten, al menos, 2 grupos amino, reactivos frente al isocionato, en una relación entre grupos NCO / grupos NH de 1:1, c) se lleva a cabo una neutralización después de la reacción, y d) se lleva a cabo una dispersión en agua después de la neutralización.
The present invention relates to a process for preparing the polyurethane dispersion, the dispersions being obtainable by a) preparing an NCO-terminated prepolymer from macrools, ionic or potentially ionic polyols, and excess polyisocyanates, b) reacting this prepolymer with compounds having at least two isocyanate-reactive amino groups, in an NCO group/NH group ratio of |
