Kaolin-based curing agent as well as preparation method and application thereof
The invention provides a kaolin-based curing agent as well as a preparation method and application thereof, and belongs to the technical field of inorganic chemical industry. The invention provides a kaolin-based curing agent. The kaolin-based curing agent is prepared from the following raw materials in parts by mass: 100 parts of kaolin, 80-250 parts of a phosphoric acid solution and 100-500 parts of water. According to the invention, kaolin is used as a base material, aluminosilicate components in kaolin are fully utilized and reacted with phosphoric acid, and silica gel and aluminum dihydrogen phosphate or aluminum monohydrogen phosphate with relatively strong cementing performance are prepared, so that the bonding performance of the curing agent is improved, and the service life of the curing agent is prolonged. After mixing with solid waste, the mechanical property of a solidified body can be greatly improved; meanwhile, silica gel and aluminum dihydrogen phosphate or aluminum monohydrogen phosphate can play a good role in curing radioactive substances, and after the curing agent is mixed with radioactive solid waste, the radioactivity of the product is greatly reduced, so that the product is more environment-friendly; the curing agent has few raw material types, so that the preparation process of the curing agent is simple.
本发明提供了一种高岭土基固化剂及其制备方法和应用，属于无机化工技术领域。本发明提供了一种高岭土基固化剂，由包括如下质量份数的原料制备得到：高岭土100份，磷酸溶液80～250份和水100～500份。本发明以高岭土作为基体材料，充分利用高岭土中的铝硅酸盐成分，使其与磷酸发生反应，制备得到具有胶结性能较强的硅胶和磷酸二氢铝或磷酸一氢铝，从而提高了固化剂的粘结性能，使得与固体废弃物混合后能够大幅度提高固化体的力学性能；同时硅胶和磷酸二氢铝或磷酸一氢铝能够对放射性物质起到很好的固化作用，将固化剂与放射性固废混合后，大幅度降低产品的放射性，使其更加环保；固化剂的原料种类少，使得固化剂的制备过程简单。
