Building block taking MTO waste catalyst as raw material and preparation method of building block
The invention discloses a building block taking an MTO waste catalyst as a raw material and a preparation method of the building block, and belongs to the technical field of waste catalyst recovery and building materials. 50-70 parts of a building block MTO waste catalyst taking the MTO waste catalyst as a raw material; 14.6 to 26.6 parts of caustic calcined magnesia powder; 5-10 parts of a filler; 8.4 to 16.6 parts of magnesium chloride hexahydrate; and 0.1 to 1.5 parts of a modifier. Wherein the ignition loss of the MTO waste catalyst is less than 15%; the water content of the filler is less than or equal to 8%. Meanwhile, the invention also provides a preparation method of the building block taking the MTO waste catalyst as the raw material. The method can solve the problem of low comprehensive performance of the prepared building block caused by difficult combination of the MTO waste catalyst with Portland cement due to large specific surface area and small pore volume, can really realize resource utilization of the MTO waste catalyst, effectively and stably solves the problem of massive stacking of the MTO waste catalyst, reduces the pollution to the environment, and is suitable for industrial production. Meanwhile, the prepared building block is high in comprehensive performance.
本发明公开了一种MTO废催化剂为原料的砌块及其制备方法，属于废催化剂回收以及建筑材料技术领域。该MTO废催化剂为原料的砌块MTO废催化剂50‑70份；轻烧镁粉14.6‑26.6份；填料5‑10份；六水氯化镁8.4‑16.6份；改性剂0.1‑1.5份。其中，所述MTO废催化剂的烧失量＜15％；所述填料的含水率≤8％。同时还提供了本发明的MTO废催化剂为原料的砌块的制备方法。本发明可以解决由于MTO废催化剂因比表面积大，孔容小难与硅酸盐水泥结合，导致制备的砌块综合性能低的问题，可以真正实现MTO废催化剂的资源化利用有效稳定的解决MTO废催化剂大量堆放的问题，降低对环境的污染，同时制备的砌块综合性能高。
