Method for preparing complex SiC ceramic through DLP printing
The invention relates to the field of materials, in particular to a method for preparing complex SiC ceramic through DLP printing. Comprising the following steps: uniformly mixing gamma-methacryloxypropyltrimethoxysilane with methanol, and carrying out hydrolytic polycondensation reaction under an acidic condition to obtain a precursor solution; adding glucose powder into the precursor solution, and uniformly mixing to obtain a photosensitive resin solution; putting the prepared photosensitive resin solution into a trough of a DLP printer, carrying out printing to obtain a ceramic green body, and carrying out post-curing to obtain a ceramic green body; and carrying out high-temperature pyrolysis on the ceramic green body according to a heating program, and cooling to obtain the SiC ceramic.
本发明涉及材料领域，具体涉及一种DLP打印制备复杂形体SiC陶瓷的方法。包括如下步骤：将γ‑甲基丙烯酰氧基丙基三甲氧基硅烷与甲醇，混合均匀，使其在酸性条件下进行水解缩聚反应，得到前驱体溶液；向前驱体溶液中加入葡萄糖粉末，混合均匀，得到光敏树脂溶液；取制备好的光敏树脂溶液放入DLP打印机的料槽中，进行打印得到陶瓷生坯，在进行后固化，得到陶瓷坯体；将陶瓷生坯按照升温程序，高温热解，冷却后得到SiC陶瓷。
