Aluminum nitride ceramic slurry based on three-dimensional photocuring molding and preparation method of aluminum nitride ceramic
The invention discloses aluminum nitride ceramic slurry based on three-dimensional photocuring molding and a preparation method of aluminum nitride ceramic, and relates to the technical field of aluminum nitride ceramic additive manufacturing. According to the preparation method of the aluminum nitride ceramic slurry based on three-dimensional photocuring molding, provided by the invention, the UV monomer with relatively strong dilutability is selected as the reactive diluent, and the aluminum nitride ceramic powder is modified by adopting the acrylic block copolymer, so that the surface wettability of aluminum nitride and the compatibility of the aluminum nitride with photosensitive resin can be effectively improved. The viscosity of the aluminum nitride ceramic slurry can be greatly reduced under the synergistic effect of the diluent and the modifier, so that the ceramic slurry which is good in photocuring capacity and low in viscosity and has the solid content of 50-70 vol% is prepared, the application of the photocuring aluminum nitride ceramic is expanded, and the high-performance aluminum nitride ceramic is prepared.
本发明公开了一种基于立体光固化成型的氮化铝陶瓷浆料、氮化铝陶瓷的制备方法，涉及氮化铝陶瓷增材制造技术领域。本发明提供的基于立体光固化成型的氮化铝陶瓷浆料的制备方法，通过选用稀释性较强的UV单体作为活性稀释剂，采用丙烯酸嵌段共聚物对氮化铝陶瓷粉体进行改性处理，能够有效提高氮化铝表面润湿性以及与光敏树脂的相容性。本发明利用稀释剂‑改性剂的协同作用，能够大幅降低氮化铝陶瓷浆料的粘度，以制备光固化能力良好，粘度低，固含量为50～70vol％的陶瓷浆料，扩展了光固化氮化铝陶瓷的应用，制备出高性能的氮化铝陶瓷。
