Preparation method of foamed ceramic thermal insulation material and product thereof
The invention discloses a preparation method of a foamed ceramic thermal insulation material and a product thereof, belongs to the field of thermal insulation materials, and aims to solve the problem of low utilization rate of ardealite. The method comprises the following steps: (1) weighing all components according to a ratio, and uniformly mixing to obtain a first intermediate; (2) carrying out ball milling on the first intermediate to prepare slurry; (3) drying the prepared slurry, and performing compression molding to obtain a foamed ceramic body; and (4) sintering the prepared foamed ceramic green body in a high-temperature furnace. The ardealite is used as the foaming agent, the fluorocarbon cerium type rare earth tailings are used as the main raw material, and the foaming ceramic material is prepared on the premise of reducing the sintering temperature through mutual cooperation with other components. Meanwhile, excessive MgO is added into the raw materials, and a new framework material is generated by controlling reaction conditions, so that the compressive strength of the finished product is effectively improved, and the method has important significance for expanding the application field and application range of the material.
本发明公开了一种发泡陶瓷保温材料的制备方法及其产品，属于保温材料领域，目的在于解决磷石膏利用率较低的问题。该方法包括如下步骤：（1）按配比称取各组分，混合均匀，得到第一中间物；（2）将第一中间物进行球磨，制备成浆料；（3）将制备的浆料干燥，并压制成型，制得发泡陶瓷坯体；（4）将制备的发泡陶瓷坯体放入高温炉中进行烧结。本申请以磷石膏为发泡剂，以氟碳铈型稀土尾矿为主要原料，通过与其他组分之间的相互配合，在降低烧结温度的前提下，实现发泡陶瓷材料的制备。同时，本申请向原料中添加过量MgO，通过控制反应条件，生成新的骨架材料，有效提升了成品的抗压强度，对于拓展材料的应用领域和适用范围，具有重要意义。
