PROBLEM TO BE SOLVED: To provide a foamed molded body in which allophone such as a sound of friction generated between molded bodies each other or when the foamed molded body and another article in contact are in friction against each other, and a sound of creaking generated when a polyolefin resin foamed molded body is compressed, is suppressed. SOLUTION: The polyolefin resin foamed molded body is obtained by feeding a polyolefin resin particle, a foaming agent, a dispersant and a dispersing aid in a closed container, elevating the temperature while the mixture is agitated to hold the inside of the closed container at a constant temperature and under constant pressure, filling a polyolefin resin foamed particle obtained by discharging the content into a lower pressure atmosphere than the inner pressure of the closed container in a mold, and heating it with steam. The surface of the foamed particle constituting the polyolefin resin foamed molded body is covered with a silicone oil. COPYRIGHT: (C)2008,JPO&INPIT |
