Abstract

PURPOSE: To shorten a curing time, by employing as a catalyst, a combination of a copper acetylacetonate (derivative) and a conventional urethane production catalyst, in the production of polyurethane by reacting an active hydrogen compound with a polyisocyanate.
CONSTITUTION: A mixture is prepared by mixing (i) an organic polyisocyanate, (ii) an active hydrogen compound, (iii) a copper acetylacetonate (derivative), (iv) a conventional urethane production catalyst such as an amine type or an organometallic type, and optionally (v) an organosilicon surfactant. Then, a inert gas such as air is uniformly dispersed throughout the mixture by stirring, and the stable foams thus produced are heat-cured to obtain foamed polyurethane. Non-foamed polyurethane can also be obtained by heat-curing the above mixture before stirring.
EFFECT: The above mixture is structually and chemically stable at temperatures below 60°C.
USE: Backings for carpets, coatings for wires and cables, safety pad panel for use in airplanes, etc., synthetic leathers.
