The invention discloses a mud-water solidifying agent for preparing a planting bag from engineering mud, a planting bag and a preparation method. The raw materials are composed of the following components: a copolymer, a crosslinking agent, acrylic acid, an initiator and a surface crosslinking agent; wherein, The copolymer is polyvinyl alcohol, acrylamide, methacrylamide or acrylonitrile; the crosslinking agent is selected from polyethylene glycol diglycidyl ether, ethoxylated glycerol triacrylate, ethylene glycol dimethyl One or more of the base acrylates. The copolymer, the cross-linking agent and the acrylic acid are mixed to carry out the polymerization reaction; the initiator is added to the solution after the polymerization reaction, the hydrogel is obtained after heating and stirring, and the hydrogel is minced to obtain gel particles; the surface is cross-linked The agent is sprayed onto the surface of the gel particles and dried to obtain a muddy water curing agent. The mud water solidifying agent of the invention can effectively modify mud and other waste sludge, and make them into planting bags, which not only saves resources and protects the environment, but also has low cost and saves transportation costs. |
