Water-permeable concrete brick loaded with metal-organic framework material and preparation method of water-permeable concrete brick
The invention discloses a water-permeable concrete brick loaded with a metal-organic framework material and a preparation method of the water-permeable concrete brick. The method comprises the following steps: mixing a silicon-aluminum material and an alkali activator to prepare geopolymer slurry, adding an organic amine reagent, mixing, and uniformly stirring to obtain modified geopolymer slurry; aggregate is added into the modified geopolymer slurry, the mixture is uniformly stirred and then loaded into a test mold, the test mold is demolded after standing for 1-2 days, a geopolymer water-permeable concrete brick is obtained, a metal salt solution is uniformly sprayed to the geopolymer water-permeable concrete brick, and the geopolymer water-permeable concrete brick is taken out after being subjected to steam curing for 3-5 h; and uniformly spraying the organic ligand solution on the cured geopolymer water-permeable concrete brick, performing steam curing for 18-22 hours, taking out the geopolymer water-permeable concrete brick after curing, and drying the geopolymer water-permeable concrete brick in a drying oven at 80-120 DEG C for 20-30 hours to obtain the water-permeable concrete brick loaded with the metal-organic framework material. The pervious concrete brick prepared by the invention has better adsorption efficiency, and can play an excellent water purification function in practical application.
本发明公开了一种负载金属‑有机骨架材料的透水混凝土砖及其制备方法，该方法包括以下步骤：将硅铝质材料与碱激发剂混合制备地聚合物浆体，加入有机胺试剂，混合后搅拌均匀得到改性地聚合物浆体；向改性地聚合物浆体中加入骨料，经搅拌均匀后装入试模中，静置1‑2d后脱模得到地聚合物透水混凝土砖，将金属盐溶液均匀喷洒至地聚合物透水混凝土砖上，进行蒸汽养护3‑5h后取出；将有机配体溶液均匀喷洒在养护后的地聚合物透水混凝土砖上，再进行蒸汽养护18‑22h，养护完成后取出并在80‑120℃的烘箱内烘干20‑30h，即得负载金属‑有机骨架材料的透水混凝土砖。本发明制备的透水混凝土砖具有较好的吸附效能，能在实际运用中发挥出优异的净水功能。
