| description | The present specification relates to a preparation method of polyketone-based resin foam particles which comprises the step of: (a) preparing a dispersion liquid including polyketone-based resin particles and an aqueous dispersion medium; (b) putting the dispersion liquid and a foaming agent into a pressure-resistant container and then pressing and heating the same at a temperature lower than the intrinsic melting point of the polyketone-based resin particles; and (c)discharging substances in the pressure-resistant container into an atmosphere under a pressure lower than that of the pressure-resistant container to form polyketone-based resin foam particles and the polyketone-based resin expanded particles.
본 명세서는 (a) 폴리케톤계 수지 입자 및 수성 분산매를 포함하는 분산액을 준비하는 단계; (b) 상기 분산액 및 발포제를 내압 용기에 넣은 후, 상기 폴리케톤계 수지 입자의 고유 융점보다 낮은 온도로 가압 가열하는 단계; 및 (c) 상기 내압 용기 내의 물질들을 상기 내압 용기의 압력보다 낮은 압력 하의 분위기로 방출시켜, 폴리케톤계 수지 발포 입자를 형성하는 단계;를 포함하는, 폴리케톤계 수지 발포 입자의 제조방법 및 폴리케톤계 수지 발포 입자에 관한 것이다. |
