Rock plate with formaldehyde degradation function and preparation method thereof
According to the rock plate with the formaldehyde degradation function, the modified nano white carbon black and the modified diatomite are added, a large number of hydroxyl groups exist on the surface of the modified nano white carbon black, the BET specific surface area is large, the modified nano white carbon black has good adsorption and degradation capacity on formaldehyde, the agglomeration phenomenon of the modified nano white carbon black can be reduced, and the mechanical property is kept not to be reduced; by adding the rare earth oxide, the strength of the rock plate material can be improved, rare earth ions are large in radius and high in oxygen coordination capacity, rare earth atoms in the rock plate structure are large in migration resistance and need to consume larger energy during migration, migration of other ions is hindered, the grain boundary migration rate is reduced, grain growth is inhibited, formation of a compact structure is facilitated, and the rock plate material is suitable for being used in a rock plate. Therefore, the purpose of improving the strength of the rock plate is achieved.
本申请提供的一种具有降解甲醛功能的岩板，通过添加改性纳米白炭黑和改性硅藻土，改性纳米白炭黑其表面上存在大量的羟基，BET比表面积大，对于甲醛有良好的吸附和降解能力且能降低改性纳米白炭黑的团聚现象，保持力学性能不下降，通过添加稀土氧化物可增加岩板材料的强度，且稀土离子半径大，与氧配位能力强，由于岩板结构中稀土原子自身迁移阻力大，迁移需要消耗更大的能量，同时也阻碍其他离子迁移，降低了晶界迁移速率，抑制晶粒生长,有利于致密结构的形成，从而达到提高岩板强度的目的。
