Preparation method of high-strength foamed ceramic
The invention provides a preparation method of high-strength foamed ceramic, which comprises the following steps: S1, carrying out ball milling on lepidolite tailings, a combustion improver sodium tetraborate and fly ash for a period of time, drying, and preparing first foamed powder according to a mass ratio of the lepidolite tailings to the combustion improver to the fly ash of (50-60): 3: (25-40); s2, transferring the first foaming powder into a ball mill, adding a metal strip, and stirring in the ball mill for a period of time to obtain second foaming powder; s3, mixing foaming agent powder with a solution for granulation to obtain a foaming material, uniformly spraying and adding the foaming material accounting for 2-5% of the weight of second foaming powder to the surface of the second foaming powder, and then granulating the second foaming material to obtain a to-be-fired material; s4, the to-be-fired material is put into a mold to be compacted and fired at the temperature of 1200-1300 DEG C, and the high-strength foamed ceramic is obtained. According to the method, the phenomenon of uneven foaming can be reduced, the temperature required by foaming is reduced, and the processing cost is reduced.
本发明提供一种高强度发泡陶瓷的制备方法，包括：步骤S1、将锂云母尾矿、助燃剂四硼酸钠、粉煤灰球磨一段时间并烘干，然后按照锂云母尾矿：助燃剂：粉煤灰＝50～60：3∶25～40的质量比配置成第一发泡粉末；步骤S2、将第一发泡粉末转移至球磨机内，加入金属条，并在球磨机内搅拌一段时间，得到第二发泡粉末；步骤S3、将发泡剂粉末与用于造粒的溶液混合得到发泡材料，并将占第二发泡粉末重量2‑5％的发泡材料均匀喷洒添加至第二发泡粉末表面，然后对第二发泡材料进行造粒，得到待烧制料；步骤S4、将待烧制料放入模具中压实并在1200℃‑1300℃烧制，得到高强度发泡陶瓷。本发明的方法可以减少发泡不均匀现象，降低发泡所需要的温度，降低加工成本。
