Method for manufacturing extruded polystyrene resin foam |
| abstract |
A method to manufacture an extruded polystyrene resin foam includes the steps for heating and mixing a nucleating agent, a fire retardant, a polystyrene resin and a physical blowing agent except chlorofluorohydrocarbons together within an extruder to prepare a polystyrene resin melt; introducing the resin melt to a die having a cooling member therein and constructed so that a molten resin flow channel within the die is broad in a vertical direction but narrows abruptly near a die orifice ;and discharging the polystyrene resin melt from the die orifice into a guider attached to a top of the die and causing it to expand within the guider. The extruded foam has an apparent density of 0.015 to 0.06 g/cm 3 . |
