Ceramic precursor slurry applicable to winding process and preparation method of ceramic precursor slurry
The invention relates to ceramic precursor slurry applicable to a winding process and a preparation method of the ceramic precursor slurry. The slurry comprises the following components in parts by weight: 100 parts of polysilazane resin, 10-150 parts of inert filler, 10-150 parts of active filler, 10-20 parts of thixotropic agent and 1-5 parts of accelerant. The method comprises the following steps: uniformly mixing polysilazane resin and an accelerant, then adding a thixotropic agent, an inert filler and an active filler, and conducting filtering to obtain a target product. Framework structure chains Si-C and Si-N of the ceramic precursor are consistent with element composition of generated silicon carbide, silicon nitride and other ceramics, only part of side groups of the precursor are broken and lost in the high-temperature inorganic process, and the high ceramic yield is achieved. Compared with the prior art, the prepared ceramic precursor slurry is moderate in viscosity, good in filler dispersity, long in storage life, low in curing cross-linking temperature and low in ceramic firing temperature, a formed cured product is free of cracking, the ceramic yield is high, the preparation process is simple, and the efficiency is high.
本发明涉及一种缠绕工艺适用陶瓷先驱体浆料及其制备方法，该浆料包括以下重量份数的组分：聚硅氮烷树脂100份、惰性填料10～150份、活性填料10～150份、触变剂10～20份、促进剂1～5份；该方法包括以下步骤：取聚硅氮烷树脂和促进剂混合均匀，然后加入触变剂、惰性填料、活性填料，经过滤得到目的产物。本发明陶瓷先驱体的骨架结构链Si‑C、Si‑N与生成的碳化硅、氮化硅等陶瓷的元素组成一致，先驱体在高温无机化过程中仅有部分侧基发生断裂而损失，具有高的陶瓷产率。与现有技术相比，本发明制备的陶瓷先驱体浆料粘度适中，填料分散性好，储存期长，具有低的固化交联温度和低的陶瓷烧成温度，成型后的固化物无开裂，陶瓷产率较高，且制备工艺简单，效率高。
