A method for preparing a resin particle having a large surface area and a shape factor (SF-1) of 110 to 800, which comprises a step of applying a shear force to an aqueous dispersion having a viscosity of 300 to 100,000 mPa·s formed by adding a thickener to an aqueous dispersion containing resin particles, and a subsequent step of decreasing the viscosity of the aqueous dispersion to 200 mPa·s or less by adding a viscosity decreasing agent as necessary. Resin particles obtained by the method can be used as additives for paint, additives for coating materials, powder coatings, additives for cosmetics, resins for slush molding, spacers for use in manufacturing electronic components or devices, standard particles for electronic measuring instruments, toners for electrophotography, toners for electrostatic recording, toners for electrostatic printing, and hot-melt adhesives.
一种制备具有大表面积且形状系数(SF-1)为 110 至 800 的
树脂颗粒的方法,其步骤包括:向含有
树脂颗粒的
水性分散液中加入
增稠剂而形成的粘度为 300 至 100,000 mPa-s 的
水性分散液施加剪切力;随后,根据需要加入降粘剂,将
水性分散液的粘度降至 200 mPa-s 或更低。通过该方法获得的
树脂颗粒可用作油漆添加剂、涂层材料添加剂、粉末涂料、化妆品添加剂、泞模
树脂、用于制造电子元件或设备的垫片、电子测量仪器的标准颗粒、电子照相调色剂、静电记录调色剂、静电印刷调色剂和热熔粘合剂。
