Abstract

En fremgangsmåte for fremstilling et ekspandert eller skummet materiale omfatter ekspandering eller skumming og etterfølgende herding av en polymer eller harpiks ved blanding av en ekspanderbar polymer eller harpiks, en katalysator i stand til å forårsake herding av polymeren eller harpiksen, et drivmiddel i stand til å generere en gass i polymeren eller harpiksen for å danne celler i denne samt en surfaktant i stand til å stabilisere celler som er dannet i polymeren eller harpiksen. Det vesentlige ved denne prosess er at surfaktanten er i det vesentlige blandbar med drivmiddel og prosessen omfatter et trinn med blanding av drivmidlet med surfaktant før blanding av disse komponenter med harpiks og/eller katalysator. Det beskrives videre en apparatur for gjennomføring av fremgangsmåten.A process for preparing an expanded or foamed material comprises expanding or foaming and subsequently curing a polymer or resin by mixing an expandable polymer or resin, a catalyst capable of causing the polymer or resin, a propellant capable of generating a gas in the polymer or resin to form cells therein, and a surfactant capable of stabilizing cells formed in the polymer or resin. The essence of this process is that the surfactant is substantially miscible with propellant and the process comprises a step of mixing the propellant with surfactant before mixing these components with resin and / or catalyst. An apparatus for carrying out the method is further described.
