Preparation method of silicon carbide foamed ceramic
The invention relates to a preparation method of silicon carbide foamed ceramic, which comprises the following steps: firstly adding 80-85% of silicon carbide powder, then adding 4-6% of sintering aid, the sintering aid comprises 1.5-2% of kaolin, 1.5-2% of silicon dioxide and 1.5-2% of aluminum oxide, the silicon dioxide is added into the silicon carbide powder, and the aluminum oxide is added into the silicon carbide powder. According to the present invention, 1.5-2% of silicon dioxide needs to be added, 1.5-2% of aluminum oxide needs to be added, and the carbonized foamed ceramic is prepared, such that the performance of the carbonized foamed ceramic is good through the adjustment of the ratio of the various raw materials, and the through hole rate of the carbonized foamed ceramic is improved through the addition of the starch, the aluminum oxide and other sintering aids; according to the method, the performance of the carbonized foamed ceramic is improved, then polyacrylamide is added, 1% of the polyacrylamide needs to be added into the carbonized foamed ceramic, extrusion molding is carried out by arranging two slurry pressing machines, the carbonized foamed ceramic can be successfully molded at a time in the molding process, repeated operation is not needed, and the production efficiency of the carbonized foamed ceramic is improved.
本发明涉及一种碳化硅泡沫陶瓷的制备方法，包括最先加入的碳化硅粉，所述碳化硅粉需要加入80％‑85％，紧接着加入烧结助剂，所述烧结助剂需要加入4％‑6％，所述烧结助剂包括高岭土、二氧化硅和三氧化二铝，所述高岭土需要加入1.5％‑2％，所述二氧化硅需要加入1.5％‑2％，所述三氧化二铝需要加入1.5％‑2％，碳化泡沫陶瓷，通过进行多种原材料配比的调整，碳化泡沫陶瓷的性能变好，通过加入了淀粉和三氧化二铝等烧结助剂，提高了碳化泡沫陶瓷的透孔率，增加了碳化泡沫陶瓷的性能，紧接着加入聚丙烯酰胺，所述聚丙烯酰胺需要加入1％，碳化泡沫陶瓷，通过设置了两台压浆机进行挤压成模，碳化泡沫陶瓷在成模过程中能够一次性成功，不需要反复的操作，以高了碳化泡沫陶瓷生产的效率。
