Thermal shock resistant ceramic material and preparation method thereof

LONG YUNHUA

The invention relates to a thermal shock resistant ceramic material and a preparation method thereof, and belongs to the technical field of building material preparation. The method comprises the following steps: firstly, taking pig hair as a raw material, performing acid leaching and sodium sulfite solution soaking treatment to partially open disulfide bonds in pig hair protein and improve the solubility of the pig hair protein, and then dissolving the pig hair protein with alkali liquor to obtain reaction filtrate rich in the pig hair protein; blending the reaction filtrate with sodium silicate and a hydrochloric acid reaction solution to prepare a self-made compound foaming agent, blending loess as a main material with other raw materials, industrial brine and the self-made compound foaming agent to prepare a slurry blank, and carrying out segmented sintering to finally prepare the thermal shock resistant ceramic material. The thermal shock resistant ceramic material prepared by themethod is high in porosity and good in thermal shock resistance, and has a wide application prospect.

本发明涉及一种抗热震陶瓷材料及其制备方法，属于建筑材料制备技术领域。本发明首先以猪毛为原料，通过酸浸和亚硫酸钠溶液浸泡处理，使得猪毛蛋白中双硫键部分打开，提高猪毛蛋白的溶解性，接着再用碱液溶解猪毛蛋白，得到富含猪毛蛋白的反应滤液，接着将其和硅酸钠、盐酸反应液共混制备得到自制复配发泡剂，随后以黄土为主料，辅以其他原料和工业卤水以及自制复配发泡剂共混制浆制坯，并分段烧结，最终制得抗热震陶瓷材料；本发明制得的抗热震陶瓷材料气孔率高，抗热震性好，具有广阔的应用前景。
