Ceramic clay and preparation method thereof
The invention provides pottery clay and a preparation method thereof, and belongs to the technical field of pottery clay. Which comprises 65-75% of a main material and 25-35% of ingredients, and is characterized in that the main material is subsoil or mixed soil of subsoil and moisture soil, the ingredients are clay and high-temperature-resistant modified kaolin, and the mass ratio of the clay to the high-temperature-resistant modified kaolin is (5-10): 12. According to the high-temperature-resistant modified kaolin disclosed by the invention, the kaolin is pretreated by acid liquor, so that the surface of the kaolin contains rich hydroxyl groups, and further under the modification action of an aluminate coupling agent, the surface of the prepared modified kaolin is connected with rich aluminate groups, so that after an organic solvent of aluminum isopropoxide is added, the high-temperature-resistant modified kaolin is prepared. The high-temperature-resistant modified kaolin can form an aluminum hydroxide shell layer on the surface of the kaolin and forms an aluminum oxide layer after being calcined, so that the prepared high-temperature-resistant modified kaolin has excellent high-temperature resistance and can obviously improve the high-temperature resistance and stability of pottery clay after being added into the pottery clay, thereby being capable of preparing ceramic products which are uniform, low in foaming content and the like, and having a wide application prospect.
本发明提出了一种陶泥及其制备方法，属于陶泥技术领域。包括65‑75％主料和25‑35％配料，其特征在于，所述主料为底土、或底土与潮土的混合土，配料为粘土和耐高温改性高岭土，质量比为5‑10:12。本发明耐高温改性高岭土通过酸液对高岭土进行预处理，使得高岭土表面含有丰富的羟基基团，进一步在铝酸酯偶联剂的改性作用下，制得的改性高岭土表面接上丰富的铝酸酯基团，从而加入异丙醇铝的有机溶剂后，能够在高岭土表面形成一层氢氧化铝壳层，经过煅烧后形成氧化铝层，因此，制得的耐高温改性高岭土具有极好的耐高温性能，加入陶泥中，能明显提高陶泥的耐高温、稳定性，从而能够制得的均一、起泡含量少等陶瓷制品，具有广阔的应用前景。
