Photocuring 3D printing manufacturing method of high-porosity ceramic core
The invention relates to a photocuring 3D printing manufacturing method of a high-porosity ceramic core, which comprises the following steps: adding graphene into inorganic powder taking aluminum oxide as a main body, uniformly mixing, and adding the mixture into photosensitive resin to obtain ceramic slurry; pouring the ceramic slurry into a photocuring 3D printer, and printing under an ultraviolet lamp curing condition to obtain a ceramic core biscuit; placing the ceramic core biscuit in a tubular furnace, and completing the degreasing process under the conditions of a certain heating rate, temperature and heat preservation time in the argon atmosphere; and transferring into a muffle furnace, and completing the removal and sintering process of the graphene under the conditions of certain heating rate, temperature and heat preservation time in an air atmosphere. According to the invention, graphene is introduced into the ceramic slurry and is removed in the heat treatment process, so that the porosity of the ceramic core is improved, the removal difficulty is reduced, and the removal process of the ceramic core is facilitated. The method can be applied to the field of production of alumina-based ceramic cores.
本发明涉及一种高气孔率陶瓷型芯的光固化3D打印制造方法，将石墨烯加入到以氧化铝为主体的无机粉体中并混合均匀，将上述混合物加入到光敏树脂中，得到陶瓷浆料；将陶瓷浆料倒入光固化3D打印机中并在紫外灯固化条件下打印得到陶瓷型芯素坯；将陶瓷型芯素坯置于管式炉中，在氩气气氛中以一定升温速率、温度、保温时间条件下完成脱脂过程；再转移至马弗炉中，在空气气氛中以一定升温速率、温度、保温时间条件下完成石墨烯的脱除及烧结过程。本发明通过在陶瓷浆料中引入石墨烯，并在热处理过程将其中除去，提高了陶瓷型芯的气孔率，降低了脱除难度，利于陶瓷型芯的脱除过程。可应用于氧化铝基陶瓷型芯的生产领域。
