Microcapsule foaming agent, preparation method thereof and mining foaming filling material
The invention discloses a microcapsule foaming agent, a preparation method thereof and a mining foaming filling material, and the preparation method of the microcapsule foaming agent comprises the following steps: adding a capsule material into a solvent, heating and stirring until the capsule material is completely dissolved; adding a foaming agent into the completely dissolved capsule material under a constant temperature condition, stirring until the foaming agent is completely dissolved, stopping heating, and cooling to room temperature to obtain a precipitate; and drying the precipitate to obtain the microcapsule foaming agent. The microcapsule foaming agent is added into a cement-based material through a simple dry mixing process to prepare the microcapsule foam mining foaming filling material, the microcapsule foaming agent does not play a role in the material water adding and stirring process, and after the materials are uniformly stirred to prepare slurry, the foaming agent is released from microcapsules, and the foam filling material is formed. The slurry acts when being prepared into a cement-based foam filling material through foaming equipment. The mining foaming filling material has the advantages of being convenient to use, small in density, good in filling integrity and high in strength.
本发明公开一种微胶囊发泡剂及其制备方法及一种矿用发泡充填材料，该微胶囊发泡剂的制备包括以下步骤：将囊材加入溶剂中，加热搅拌至所述囊材完全溶解；恒温条件下，将发泡剂加入完全溶解后的囊材中，搅拌至所述发泡剂完全溶解后，停止加热，冷却至室温，得到沉淀物；将沉淀物干燥后，制得微胶囊发泡剂。将该微胶囊发泡剂通过简单的干混过程加入至水泥基材料中，制得微胶囊泡沫矿用发泡充填材料，该微胶囊发泡剂在材料加水搅拌过程中不发挥作用，搅拌均匀制成浆体后，发泡剂从微胶囊内被释放出来，浆体通过发泡设备制成水泥基泡沫充填材料时进行作用。该矿用发泡充填材料具备使用便捷、密度小、填充整体性好以及强度高的优点。
