Low-shrinkage ceramic product and preparation method thereof
The invention discloses a preparation method of a low-shrinkage ceramic product. The preparation method comprises the following steps: preparing a slurry basic raw material; preparing the slurry basic raw material into low-shrinkage slurry; aging the low-shrinkage slurry, performing pressure forming by using a high-pressure resin mold, and drying to obtain a green body; and sintering the green body to obtain the low-shrinkage ceramic product. Wherein the mud basic raw materials comprise the following components in parts by weight: 10-25 parts of potassium sodium sand, 5-15 parts of pyrophyllite, 0.5-2 parts of dolomite, 1.0-3.0 parts of calcined talc, 20-35 parts of washed mud, 10-20 parts of porcelain clay, 2-5 parts of calcined bauxite, 5-10 parts of calcined kaolin and 1-3 parts of spodumene. The prepared low-shrinkage ceramic product has the characteristics of low shrinkage rate, low water absorption rate and high strength.
本发明公开了一种低收缩陶瓷制品的制备方法，包括以下步骤：准备泥浆基础原料；将所述泥浆基础原料制成低收缩泥浆；所述低收缩泥浆陈腐后利用高压树脂模具完成压力成型，干燥后得到坯体；所述坯体经烧成后得到低收缩陶瓷制品；其中，所述泥浆基础原料按重量份计包括：钾钠砂10～25份、叶腊石5～15份、白云石0.5～2份、煅烧滑石1.0～3.0份、水洗泥20～35份、瓷土10～20份、煅烧铝矾土2～5份，煅烧高岭土5～10份、锂辉石1～3份。本发明制得的低收缩陶瓷制品兼具收缩率低、吸水率低、强度高的特点。
