titleOfInvention |
Method for manufacturing foamed polypropylene-resin particles |
abstract |
Foamed polypropylene-resin particles are obtained by dispersing polypropylene-resin particles containing polyethylene glycol and/or glycerin together with an aqueous dispersion medium in a pressure-resistant container; introducing carbon dioxide gas as a foaming agent into the pressure-resistant container; impregnating the polypropylene-resin particles with the foaming agent under a heating and pressure condition; and then discharging the polypropylene-resin particles into an area having a lower pressure than an internal pressure of the pressure-resistant container and having an atmosphere temperature of higher than 80°C and not higher than 110°C. The foamed polypropylene-resin particles can yield an in-mold foam molded body at a low heated water vapor pressure for molding, do not lose moldability at a high heated water vapor pressure for molding, have a wide heated water vapor range for molding, exhibit good moldability even when a mold with a complicated shape, a large mold, or a similar mold is used. |
