Foamed ceramic and preparation method thereof
The invention relates to the field of advanced ceramic manufacturing, and particularly discloses foamed ceramic and a preparation method thereof.The foamed ceramic is formed by soaking a sponge supporting body in zirconia ceramic slurry and then conducting high-temperature sintering, the sponge supporting body is obtained by conducting photocuring 3D printing on a mixed photosensitive material, and the mixed photosensitive material comprises mixed photosensitive resin; the mixed photosensitive resin comprises the following raw materials in parts by weight: 30-60 parts of epoxy acrylate; 40 to 70 parts of a reactive diluent; 1-5 parts of a free radical photoinitiator; 50 to 70 parts of aliphatic epoxy resin; 30 to 50 parts of hydroxybutyl vinyl ether; and 1-5 parts of a cationic photoinitiator. Correspondingly, the invention also discloses a preparation method of the foamed ceramic. By adopting the preparation method, the foamed ceramic has the advantages of high through hole rate, high mechanical property and the like, and the product is good in stability and high in percent of pass. Moreover, the process is simple, cost is reduced, high efficiency and rapidness are achieved, energy is saved, consumption is reduced, and industrial application can be achieved.
本发明涉及先进陶瓷制造领域，具体公开了一种泡沫陶瓷及其制备方法，其由海绵支撑体浸泡于氧化锆陶瓷浆料后经高温烧结形成，其中，所述海绵支撑体由混合光敏材料经过光固化3D打印制得，所述混合光敏材料包括混合光敏树脂，所述混合光敏树脂以重量份计包括下述原料：30份~60份环氧丙烯酸酯；40份~70份活性稀释剂；1份~5份自由基光引发剂；50份~70份脂肪族环氧树脂；30份~50份羟丁基乙烯基醚；1份~5份阳离子光引发剂。相应的，本发明还公开了泡沫陶瓷的制备方法。采用本发明，所述泡沫陶瓷具有高通孔率和高力学性能等优点，产品的稳定性好、合格率高。而且，工艺简单，降低成本，高效快速、节能降耗，能产业化应用。
