Abstract
The present invention relates to a polyurethane resin composition for preparing a polyurethane composite, having (a) an organic polyisocyanate; (b) an isocyanate-reactive component having (b1) one or more polyether carbonate polyols which are prepared by addition of carbon dioxide and alkylene oxides onto starters having active hydrogen using DMC catalysts, and (b2) one or more polyols which have a functionality of 2-6 and are selected from polyether polyols, polyester polyols, polymer polyols or combinations thereof; and (c) a blowing agent having an amount of 0-0.2 wt. % based on 100% by weight of the isocyanate-reactive component (b).
