摘要： This invention is directed to a process and apparatus for mixing a pulverulent or small particle size additive into at least one of the liquid reaction components for the preparation of a reaction mixture which forms a solid substance or a foam, wherein the reaction components are introduced into separate chambers and subjected to turbulence by stirring and the pulverulent additive is stirred into at least one of the reaction components and that liquid reaction component charged with the additive is transferred into a second reaction component and mixed therewith. The liquid reaction component to which the pulverulent additive is to be introduced is charged into a closed chamber to a predetermined fill level, the chamber is sealed off and a vacuum is applied above the fill level, then the additive is introduced into the chamber below the liquid level by means of the vacuum and is uniformly distributed within the liquid reaction component by the turbulence produced by stirring, while the reaction component and the additive are freed from the air carried with them by the degassing effect of the vacuum.

摘要： A process is described for the production of optionally cellular polyurethane moldings with an elevated ground material/filler content, which process broadly comprises a) mixing and reacting an aromatic di- or polyisocyanate with a di- and/or polyol of a molecular weight of 1,000 to 20,000 in a quantity insufficient to react with all the NCO groups to yield an isocyanate pre-adduct with an NCO group content of 5 to 32%, b) mixing this isocyanate pre-adduct with ground material/filler, c) mixing the resultant mixture, with a di- and/or polyol with a molecular weight of 62 to 2,000 (crosslinking agent), and optionally water and/or an organic blowing agent, in a static mixer and d) introducing the resultant mixture into a mold.
