Abstract
Oppfinnelsen tilveiebringer organiske Polyisocyanatblandinger som omfatter en polyisocyanatbestanddel og et ikke-ionisk overflateaktivt middel som er fritt for isocyanatreaktive grupper, kjennetegnet ved at polyisocyanatbestanddelen omfatter et isocyanatholdig reaksjonsprodukt av et uretonimin-modifisert polyisocyanat og en polyol med en molekylvekt fra 500 til 10 000. Oppfinnelsen tilveiebringer videre vandige emulsjoner avledet fra polyisocyanatblandingene, en fremgangsmåte for anvendelse av disse for å binde polyuretan-skumavfall og skumkompositter fremstilt ved hjelp av fremgangsmåten.The invention provides organic Polyisocyanate compositions comprising a polyisocyanate component and a nonionic surfactant free of isocyanate reactive groups, characterized in that the polyisocyanate component comprises an isocyanate containing reaction product of a uretonimine-modified polyisocyanate and a polyisocyanate-modified polyisocyanate reaction product. further, aqueous emulsions derived from the polyisocyanate mixtures, a process for using them to bind polyurethane foam waste and foam composites prepared by the process.
