DLP photocuring 3D printing lead metaniobate piezoelectric ceramic slurry and preparation method thereof
The invention discloses DLP photocuring 3D printing lead metaniobate piezoelectric ceramic slurry and a preparation method thereof. The preparation method comprises the following steps: preparing lead metaniobate piezoelectric ceramic pre-sintered powder; preparing lead metaniobate piezoelectric ceramic slurry for DLP (Digital Light Processing) photocuring 3D (Three Dimensional) printing; carrying out DLP photocuring 3D printing on the piezoelectric ceramic green body; and degreasing and sintering the 3D printing lead metaniobate piezoelectric ceramic green body to obtain the piezoelectric ceramic material. The free radical photosensitive resin and the auxiliaries are selected for combination, so that the slurry is high in solid content, good in fluidity and high in curing speed, the printing and ceramic preparation requirements are met, and the sintered piezoelectric ceramic is high in density and good in piezoelectric property.
本发明公开了一种DLP光固化3D打印偏铌酸铅压电陶瓷浆料及其制备方法，制备方法包括：制备偏铌酸铅压电陶瓷预烧粉体；制备DLP光固化3D打印用偏铌酸铅压电陶瓷浆；DLP光固化3D打印压电陶瓷生胚；将3D打印偏铌酸铅压电陶瓷生坯进行脱脂、烧结，得到压电陶瓷材料。本发明选取自由基光敏树脂和助剂组合，使浆料固含量高、流动性好、固化速度快，满足打印及陶瓷制备要求，烧结后压电陶瓷的致密度高，压电性能好。
