    • Problems to be solved. A conventional molding method of an expandable polymer resin employs a high-temperature heat transfer medium to perform high-temperature fusion of expandable polymer resin particles and thus suffers from high energy and time consumption due to heating and cooling of a mold and thus reduced production efficiency. Solutions. As such, the present invention provides a method for molding an expandable polymer resin-molded material at a low temperature and a molding apparatus for use in practicing the same. In accordance with the present invention, pre-expanded particles of expandable polymer resin are coated with a solution of a coating resin having a softening temperature lower than that of the expandable polymer resin to form skin layers on surfaces of expanded particles and expanded resin is then molded by fusion of these skin layers. Additional expansion of the expandable polymer resin, or provision of external physical pressurizing force, or simultaneous use of both obtains pressure necessary for the molding process. In any case, it is possible to perform the molding process at significantly lower temperature than in conventional methods.
    • 需要解决的问题 可膨胀聚合物树脂的常规模塑方法采用高温传热介质来进行可膨胀聚合物树脂颗粒的高温熔融,因此由于模具的加热和冷却而遭受高能量和时间消耗,从而降低了生产效率 。 解决方案。 因此,本发明提供了一种在低温下模制可膨胀聚合物树脂模制材料的方法和用于实施该方法的成型装置。 根据本发明,可膨胀聚合物树脂的预发泡颗粒用软化温度低于可发性聚合物树脂的涂层树脂的溶液涂覆,以在发泡颗粒的表面上形成表层,然后发泡树脂 通过这些皮肤层的融合而模制。 可膨胀聚合物树脂的额外膨胀,或提供外部物理加压力或同时使用二者获得模制过程所需的压力。 在任何情况下,可以以比常规方法低得多的温度进行模塑加工。
