Preparation method and preparation device of graphene cement additive
The invention discloses a preparation method and a preparation device of a graphene cement additive. The preparation method comprises the following steps: weighing preparation raw materials, preparing premixed slurry, preparing additive powder, and packaging and storing a finished product. By adding the graphene powder, the graphene cement additive can effectively refine the pore structure of a cement base material and improve the breaking strength and compressive strength of the cement base material, and by adding the dendritic polyamidoamine, the dissolving amount of effective components in the mixing process is increased, and the interaction of the surfaces of various materials is increased. A graphene cement additive can improve the fluidity of a cement mixture by adding a water reducing agent, the graphene cement additive can improve the compactness and impermeability of a cement base material by adding an inorganic salt, and the workability of cement is improved and hydration heat is reduced by adding superfine slag powder, and therefore a problem that cement base materials are liable to crack is avoided. The preparation method disclosed by the invention is scientific and rigorous, and the process is simple and easy to operate.
本发明公开一种石墨烯水泥添加剂的制备方法及其制备装置，其制备方法包括以下步骤：称取制备原料、预混浆料制备、添加剂粉体制备和成品包装存储；本发明通过加入石墨烯粉体使石墨烯水泥添加剂可以有效细化水泥基材的孔结构并提高其抗折强度和抗压强度，通过树枝状聚酰胺胺的加入提高了混合过程中有效成分的溶解量，增加多种材料表面的相互作用，通过减水剂的加入使石墨烯水泥添加剂可以改善水泥拌合物的流动性，过无机盐的加入使石墨烯水泥添加剂可以提高水泥基材的密实性和抗渗性，通过矿渣微粉的加入提高了水泥的易和性并减少水化热，从而避免了水泥基材容易产生裂缝的问题，且本发明的制备方法科学严谨，工艺简单易操作。
