Preparation method of ceramic material for 3d printing
The invention discloses a preparation method of a ceramic material for 3d printing, which belongs to the technical field of composite materials. The ceramic material for 3d printing is prepared from nano zirconium oxide powder, hydroxyl-terminated polydibutene, PAN carbon fibers, propyl gallate, a spiro orthocarbonate expansion monomer, a photoinitiator, a dispersing agent, a coupling agent, bentonite and silicon nitride ceramic powder. The size is not obviously shrunk through temperature treatment, the surface is smooth, the texture is hard, the shrinkage rate in the length direction is 9.8%-10.2%, the shrinkage rate in the width direction is 10.9%-11.3%, and the internal structure is not obviously changed. The spiro orthocarbonate expansion monomer and the hydroxyl-terminated polydibutene system are soft and are suitable for printing. The material has the advantages of small powder particle size, narrow particle size distribution, favorable flowability, favorable matching property with the molding speed of a 3d printer, stable product properties, high precision, favorable environmental benefit and favorable economic benefit.
本发明公开了一种3d打印用的陶瓷材料的制备方法，属于复合材料技术领域。该3d打印用的陶瓷材料由纳米氧化锆粉末、端羟基聚二丁烯、PAN碳纤维、没食子酸丙酯、螺环原碳酸酯类膨胀单体、光引发剂、分散剂、偶联剂、膨润土和氮化硅陶瓷粉组成。本发明中温度处理对尺寸没有明显收缩，其表面光滑、质感坚硬，长度方向收缩率9.8％～10.2％，宽度方向收缩率为10.9％～11.3％，内部结构并未发生明显变化。本发明中利用螺环原碳酸酯类膨胀单体和端羟基聚二丁烯体系质软，适合打印。其粉体颗粒小，粒径分布窄，流动性较好，与3d打印机成型速度匹配性较好，产品性质稳定，精度高,具有良好的环境效益和经济效益。
