Graphene water reducing agent as well as preparation method and application thereof
The invention discloses a graphene water reducing agent as well as a preparation method and application thereof. The graphene water reducing agent is prepared from the following raw materials: isopentenol polyoxyethylene ether, isopentyl tetraacrylate, 2-acrylamide-1-methylpropanesulfonic acid, unsaturated phosphate ester, graphene oxide, 3-mercaptopropionic acid, ascorbic acid, an initiator and water. The invention also provides a preparation method of the composition. Compared with the prior art, the prepared graphene water reducing agent has water reducing performance, slump retaining performance, early strength and slow release performance, graphene oxide is effectively dispersed, the graphene water reducing agent has excellent adaptability to cement and concrete, the morphology of the cement is improved, growth of cement hydration products is promoted, the internal structure of cement mortar is compact, and the water reducing agent has good water reducing performance. The star-shaped graphene water reducing agent prepared by the preparation method disclosed by the invention can be dissociated from a hydrolysis center, so that good neat paste flowability is kept.
本发明公开了一种石墨烯减水剂及其制备方法和应用。该石墨烯减水剂包括以下原料:异戊烯醇聚氧乙烯醚、四丙烯酸异戊四酯、2‑丙烯酰胺‑1‑甲基丙磺酸、不饱和磷酸酯、氧化石墨烯、3‑巯基丙酸、抗坏血酸、引发剂、水。本发明还提供了其制备方法。与现有技术相比,本发明制备的石墨烯减水剂具备减水性能、保坍、早强、缓释性能,且有效分散氧化石墨烯,对水泥、混凝土具有优异的适应性能,且改善水泥形貌,存进水泥水化产物的生长,使水泥砂浆内部结构紧凑,进一步提高水泥砂浆的抗压、抗弯曲强度、本发明制备的星状石墨烯减水剂可从水解中心解离,使得保持良好的净浆流动性。
