Self-cleaning heat-resistant ceramic and preparation method thereof
The invention relates to self-cleaning heat-resistant ceramic and a preparation method thereof, and belongs to the technical field of ceramic. The invention discloses a preparation method of self-cleaning heat-resistant ceramic. The ceramic preparation process comprises the steps of green body preparation, overglaze spraying, coating spraying, calcination and water repellent agent soaking. The albite and the quartz in the cover glaze react to generate sodium calcium silicate, so that the hardness and the wear resistance of the ceramic are improved. The coating is formed by compounding an antibacterial agent and nano cerium dioxide, and a dispersing agent is added to prevent agglomeration, so that the antibacterial property of the ceramic is enhanced, and the self-cleaning property of the ceramic is enhanced. The nano cerium dioxide has hydrophobicity and heat-resistant stability, and the nano cerium dioxide is subjected to surface modification through a hydrophobing agent soaking process, so that the hydrophobicity of the ceramic is further enhanced. Therefore, the self-cleaning heat-resistant ceramic which has antibacterial property, heat resistance and super-hydrophobicity and is environment-friendly can be prepared through the process steps.
本发明涉及一种自清洁耐热陶瓷及其制备方法，属于陶瓷技术领域。本发明公开了自清洁耐热陶瓷的制备方法，陶瓷制备的工艺步骤包括了生胚—喷涂面釉—喷涂层—煅烧—疏水剂浸泡。面釉中的钠长石和石英反应生成硅酸钠钙酸盐，增加陶瓷的硬度和耐磨性。涂层由抗菌剂和纳米二氧化铈复配而成，并加入分散剂防止发生团聚，增强了陶瓷的抗菌性从而增强陶瓷的自洁性。纳米二氧化铈具有疏水性和耐热稳定性，通过疏水剂浸泡工艺对纳米二氧化铈进行表面修饰，进一步增强了陶瓷的疏水性能。因此，本发明通过该工艺步骤可制备出具有抗菌性、耐热性和超疏水性，并且环保的自清洁耐热陶瓷。
