| titleOfInvention | Method for producing expanded beads of thermoplastic resin |
| abstract | (57) [Summary] [Objective] A method for producing expanded particles with a high expansion ratio in a method of producing expanded particles by mixing the thermoplastic resin in an extruder using a gas as an expanding agent and then extruding the mixture. To provide a way to do it. In the method for producing expanded particles of a thermoplastic resin, (1) a step of injecting a gas into the thermoplastic resin in an extruder to mix and dissolve the resin, and (2) a thermoplastic resin-gas mixture in a molten state, From a die having a plurality of extrusion holes attached to an extruder, the pressurized liquid is extruded into a first-stage pressure vessel of a plurality of pressure vessels containing at least two or more in series, and Cutting with a cutting blade that moves along the front surface to obtain primary expanded particles, (3) A step of transferring the primary expanded beads together with a liquid to a second pressure resistant container having an internal pressure lower than that of the first pressure resistant container to further increase the expansion ratio of the primary expanded particles to obtain secondary expanded particles. , (4) Furthermore, if necessary, the expanded particles and the liquid are sequentially transferred to a pressure-resistant container of the third stage or lower, where the pressure is low, And a step of sequentially increasing the expansion ratio. |
