Photocuring forming preparation method of high-strength fused quartz ceramic
The invention discloses a photocuring forming preparation method of high-strength fused quartz ceramic, and belongs to the technical field of photocuring forming. Comprising the following steps: blending fused quartz powder with a modifier I and a modifier II to prepare mixed powder, performing wet grinding, drying and sieving to obtain modified fused quartz powder; mixing the prepolymer I, the prepolymer II, a resin monomer I, a resin monomer II, a photoinitiator I and a photoinitiator II to prepare a photosensitive resin system; adding a dispersing agent into the photosensitive resin system, uniformly mixing, then adding the modified fused quartz powder and SiC powder, and uniformly mixing, so as to prepare fused quartz ceramic photocuring slurry; carrying out printing forming, degreasing treatment and sintering on the fused quartz ceramic photocuring slurry to obtain fused quartz ceramic; the use amount of the SiC powder is 1wt%-5wt% of the mass of the modified fused quartz powder. The preparation method can reduce the curing depth of the fused quartz, improve the forming precision and improve the sintering density of the fused quartz.
本发明公开了一种高强度熔融石英陶瓷的光固化成型制备方法，属于光固化成型技术领域。包括以下步骤：将熔融石英粉末与改性剂一、改性剂二共混，制得混合粉末，后进行湿磨，再经干燥、过筛后得到改性熔融石英粉末；将预聚物一、预聚物二、树脂单体一、树脂单体二、光引发剂一、光引发剂二混合制得光敏树脂体系；将分散剂加入光敏树脂体系混合均匀，再加入改性熔融石英粉末与SiC粉末混合均匀，制得熔融石英陶瓷光固化浆料；对熔融石英陶瓷光固化浆料进行打印成型、脱脂处理和烧结，得到熔融石英陶瓷；SiC粉末用量为改性熔融石英粉末质量的1wt％～5wt％。该制备方法能够降低熔融石英固化深度、改善成型精度，同时提高熔融石英烧结致密度。
