摘要 |
<p>A foamed plastic manufactured by foaming a mixture of a resin and a volatile polymerizable foaming agent, wherein the pressure in the foams of the foamed plastic is less than atmospheric pressure, is disclosed. Further, a foamed plastic manufactured by hermetically sealing with an airtight film and foaming a mixture of a resin and a volatile polymerizable foaming agent, wherein the pressure in a gap region between the airtight film and the foamed plastic and the pressure in the foams of the foamed plastic are less than atmospheric pressure is disclosed. Further, a method of manufacturing foamed plastic comprising foaming a mixture of a volatile polymerizable foaming agent and a resin, and irradiating the foamed plastic with an energy beam. According to the invention, to enhance the heat insulation and soundproof performance a volatile liquid polymerizable monomer is used as foaming agent, and irradiated with an energy beam to polymerize the foaming agent after forming, and to maintained a reduced internal pressure, the foamed plastic is further covered by a metal film or laminated film. <IMAGE></p> |
