Disclosed are polyphenylene sulfide microparticles characterized in that a linseed oil absorption amount is in a range of 40 to 1,000 mL/100 g and a number average particle diameter is in a range of 1 to 200 µm. According to the present invention, it is possible to obtain porous PPS microparticles in a practically applicable level, which has been difficult to produce in the prior art. Porous PPS microparticles of the present invention have a large specific surface area and therefore promote fusion of particles when molded into various molded bodies by applying thermal energy, thus enabling formation or molding of a coating layer of particles at a lower temperature in a shorter time. Porous PPS microparticles of the present invention have a porous shape and therefore enable scaterring light in multiple directions and suppression of specific reflection of reflected light in a specific direction, thus making it possible to impart shading effect and matt effect when added to a medium.
本发明公开了
聚苯硫醚微粒,其特征在于亚麻籽油吸收量在 40 至 1,000 mL/100 g 之间,平均颗粒直径在 1 至 200 µm 之间。根据本发明,可以在实际应用中获得多孔 P
PS 微颗粒,这在现有技术中很难生产。本发明的多孔 P
PS 微颗粒具有较大的比表面积,因此在通过热能模塑成各种模塑体时可促进颗粒的融合,从而能够在较短的时间内以较低的温度形成或模塑颗粒的涂层。本发明的多孔聚
苯乙烯微粒具有多孔形状,因此可在多个方向上散射光线,并抑制反射光在特定方向上的特定反射,从而在添加到介质中时可产生遮光效果和亚光效果。
