Ceramic material as well as preparation method and application thereof
The invention relates to a ceramic material as well as a preparation method and application thereof. The method comprises the following steps: mixing 5-80% of a grinding material and 20-95% of a sintering aid to obtain a ceramic composition, wherein the grinding material is at least one selected from PcBN, diamond and Ti (C, N), and the sintering aid is glass powder containing SiO2, B2O, Al2O3 and CaO; mixing the ceramic composition with a premixed liquid to obtain ceramic slurry; adding a foaming agent, a catalyst and an initiator into the ceramic slurry, and carrying out stirring at a high speed; and injecting the foamed ceramic slurry into a mold, conducting curing and sintering to obtain the ceramic material. The technical problem to be solved is to prepare the ceramic material with a porosity of greater than or equal to 40% from the ceramic composition through atmospheric and low-temperature sintering, so the thermal conductivity of a cutter material and the lubricity of a cutting fluid to the cutter material are improved, and the grinding efficiency of the cutter material is improved; and the size of the prepared material is not limited, batch production can be realized, production efficiency is high, cost is lower, and the method is more practical.
本发明是关于一种陶瓷材料及其制备方法和应用。所述方法包括以下步骤：将5～80％磨削材料和20～95％烧结助剂混合得陶瓷组合物；磨削材料选自PcBN、金刚石或Ti(C，N)中的至少一种；烧结助剂为包含SiO2、B2O、Al2O3和CaO的玻璃粉；将陶瓷组合物与预混液混合得到陶瓷料浆；向陶瓷料浆中加入发泡剂、催化剂和引发剂，高速搅拌；将发泡的陶瓷料浆注入模具中固化，烧结，得到陶瓷材料。所要解决的技术问题是将陶瓷组合物通过大气气氛、低温烧结制备成孔隙率≥40％的陶瓷材料，提高刀具材料的热传导性及切削液对刀具材料的润滑性，提高了刀具材料的磨削效率；所制备的产品尺寸不受限制，可批量生产，且生产效率高，成本更经济，从而更加适于实用。
