Abstract

The invention discloses a spheroidization method of polyether-ether-ketone-hydroxyapatite (Peek-HA) 3D printing powder. The spheroidization method comprises the following steps: (1) mechanically grinding Peek-HA to obtain first Peek-HA powder; (2) placing the first Peek-Ha powder into a rotating apparatus with fluid, then starting the rotating apparatus to allow the fluid to flow and to scour the first Peek-HA powder, filtering to obtain a filter cake, and preparing second Peek-HA powder; and (3) dispersing the second Peek-HA powder into a silane coupling agent, and then drying to obtain the polyether-ether-ketone-hydroxyapatite 3D printing powder. The polyether-ether-ketone-hydroxyapatite 3D printing powder spheroidized by virtue of the method has excellent sphericity, so that the reflective rate is effectively decreased.

Description

technical field [0001] The invention relates to post-treatment of polyetheretherketone-hydroxyapatite, in particular to a method for spheroidizing polyetheretherketone-hydroxyapatite 3D printing powder. Background technique [0002] 3D printing materials are an important material basis for the development of 3D printing technology. To some extent, the development of materials is a decisive factor that determines whether 3D printing can be more widely used. At present, 3D printing materials mainly include engineering plastics, photosensitive resins, rubber materials, metal materials and ceramic materials. [0003] Engineering plastics refer to industrial plastics used as industrial parts or housing materials, which are required to have excellent strength, impact resistance, heat resistance, hardness and anti-aging properties. Commonly used are ASA plastics, PC plastics, polyester Ether ether ketone-hydroxyapatite (Peek-HA), Dragon, etc. During the 3D printing process, due t...
