Abstract

PURPOSE: To obtain a foamed body of resin having concave patterns of vermicular shape on its surface and being superior in sound-absorbing and heat-insulating properties by washing in water the foamed body of urethane resin formed by using a frame provided with a water-soluble filler in the bottom thereof.
CONSTITUTION: A water-soluble filler 2 prepared by congealing a water-soluble or water-dispersive inorganic substance (porous diatomaceous earth, CaCO3, etc.) in a vermicular state is provided at intervals on the bottom surface of a frame 1 and then a forming material 4 for a foamed body of urethane resin is injected in a concave part 5, being covered with an upper lid 6. Next, the concave part 5 being heated, the forming material 4 is foamed and hardened, thus a rigid foamed body 3 of urethane resin being formed. After the body being taken out from the concave part 5, the high-pressure water is jetted against the surface of the body and the water-soluble filler 2 is melted away by washing in water, thereby vermicular- formed concave patterns 7 being arranged irregularly are formed on the surface of the foamed body 3.
