SELF-CROSSING DISPERSION FOR DRESSING GLASS-FIBER ON THE BASIS OF POLYURETHANE, POLYURETHANE-POLYUREA OR POLYUREA, A METHOD OF ITS PRODUCTION AND A SIZING COMPOUND FOR THE GLASS-FIBER ON ITS BASIS Russian patent published in 2005 - IPC

Abstract RU 2252942 C2

FIELD: self-crossing dispersion for dressing of glass-fiber.

SUBSTANCE: the invention is pertaining to the field of the self-crossing dispersion for dressing of glass-fiber on the basis of polyurethane, polyurethane-polyurea or polyurea used for dressing glass-fiber. The invention is also dealt with a method of production of the indicated dispersion and with a sizing compound for glass-fiber. The indicated dispersion contains the blocked isocyanate groups bound with the polymer and in addition the reaction-capable hydroxyl or amino groups bound with the polymer. The dispersion is stable at storing up to 50 °C and is self-crossing at the temperature of 90°C up to 280°C. The dispersion represents a reaction product - a) at least one polyolic component; b) at least one di-, tri- and / or a polyisocyanate component, c) at least one hydrophilic nonionic or a (potentially) ionic component; d) at least one component, which is distinct from a)- or b)-, having molecular mass - 32-500 and at least one isocyanate-reaction capable group; and e) at least one monofunctional blocking component. The offered dispersions are suitable for use in the capacity of coatings for mineral emulsion carriers, textile and leather, lacquers and polishes for wood, and also may be applied as paint primers, bases, joint fillers or finishing coatings.

EFFECT: the invention allows to use the dispersions as coatings for mineral emulsion carriers, textile and leather, lacquers and polishes for wood and to applied them as paint primers, bases, joint fillers or finishing coatings.
