Porous lightweight ceramic particle and preparation method thereof
The invention discloses a porous lightweight ceramic particle and a preparation method thereof, and relates to the technical field of new materials. The preparation method comprises the following steps: modifying sodium lignin sulfonate by using 1, 6-dibromohexane and phloroglucinol to obtain modified lignin, mixing the modified lignin with paraffin, silicon powder, zinc powder and sodium sulfate to obtain a pore-foaming agent, mixing the pore-foaming agent with a sintering aid, kaolin, potassium feldspar and aluminum oxide powder to obtain mixed powder, and finally, carrying out compression molding on the mixed powder, and carrying out three-stage sintering to obtain the porous lightweight ceramic particles. The porous lightweight ceramic particles prepared by the preparation method disclosed by the invention have relatively good porosity and relatively good compressive strength.
本发明公开了一种多孔的轻质陶瓷颗粒及其制备方法，涉及新材料技术领域。本发明先用1，6‑二溴己烷和间苯三酚对木质素磺酸钠改性后制得改性木质素，然后将改性木质素与石蜡、硅粉、锌粉和硫酸钠混合，制得致孔剂，然后将致孔剂与烧结助剂、高岭土、钾长石和氧化铝粉末混合，制得混合粉末，最后将混合粉末压制成型并经过三段式烧结，制得多孔的轻质陶瓷颗粒。本发明制备的多孔的轻质陶瓷颗粒具备较好的孔隙率，且抗压强度较好。
