Recycling method of leftover materials generated by tape casting
The invention belongs to the field of ceramic powder preparation, and discloses a recycling method of leftover materials generated by tape casting. Comprising the following steps: (1) collecting leftover materials, and carrying out glue discharging treatment; (2) mixing deionized water and absolute ethyl alcohol to prepare a mixed solution, and mixing the material subjected to glue removal treatment in the step (1) with the mixed solution to obtain slurry; (3) carrying out ball milling treatment on the slurry obtained in the step (2); and (4) filtering, drying and sieving the material subjected to ball milling treatment in the step (3) to obtain target powder. According to the low-temperature glue discharging method, a large amount of additives such as organic binders and plasticizers in the green body are rapidly discharged through the glue discharging furnace, and the ceramic powder can be obtained. The ceramic intermediate product subjected to glue removal is subjected to ball milling to obtain ceramic powder with relatively good dispersity, and the ceramic powder can be subjected to re-batching.
本发明属于陶瓷粉体制备领域，公开了一种流延产生边角料的回收方法。包括以下步骤：（1）收集边角料，进行排胶处理；（2）去离子水与无水乙醇混合配置混合液，将步骤（1）排胶处理完成后的物料与混合液混合，得到浆料；（3）将步骤（2）得到的浆料进行球磨处理；（4）将步骤（3）球磨处理后的物料过滤、烘干，过筛后得目标粉体。本发明的低温排胶方法通过排胶炉快速、大量地排除了生坯中的有机粘结剂、增塑剂等添加剂，可得到陶瓷粉末。排胶后陶瓷中间产品，经过球磨之后，得到了具有较好的分散性的陶瓷粉末，可进行再次配料。
