Preparation method of difficult-to-cure ceramic based on photocuring forming and product
The invention belongs to the related technical field of photocuring forming, and discloses a preparation method of a difficult-to-cure ceramic based on photocuring forming and a product. The method comprises the following steps: S1, selecting photosensitive resin, polyethylene glycol, a dispersing agent and a photoinitiator, mixing to form a uniformly mixed solution, adding ceramic powder into the mixed solution, and stirring to obtain ceramic slurry; s2, adding polymer microspheres with low absorbance and refractive index into the ceramic slurry, and performing vacuum stirring and defoaming treatment to obtain composite ceramic slurry with uniform components; s3, presetting photo-curing forming process parameters, performing photo-curing forming through the composite ceramic slurry, obtaining a ceramic biscuit, and performing glue discharging and reactive sintering treatment on the ceramic biscuit so that the needed high-performance ceramic part is obtained. According to the invention, the photocuring manufacturing problems of high refractive index and high absorbance of ceramic powder such as silicon carbide, silicon nitride, barium titanate and lead zirconate titanate are solved, and the photo-curing forming material system is greatly expanded.
