Abstract

The invention relates to a preparation method of acrylonitrile-butadiene-styrene polymerized composite microspheres for 3D printing. According to the preparation method, polystyrene microspheres are taken as kernels, are subjected to emulsion polymerization and are prepared into composite microspheres through being grafted copolymerized with butadiene monomers, acrylonitrile monomers and styrene monomers. By taking mono-dispersed polystyrene microspheres as kernels, materials can generate relatively independent core in the polymerization process, so that the high uniformity and dispersibility of particle sizes of the composite microspheres are guaranteed, and the powder is good in fluidity and is not agglomerated; particularly, the disperse polymers are nodulized in a high-speed rotation of airflow by virtue of a centrifugal spray dryer, so as to form high-sphericity composite microspheres; various requirements of 3D printing to powder materials can be completely met, and a prepared product has excellent and stable performance and good processability.
