More Information
Summary:The invention belongs to the technical field of gypsum admixtures, and particularly relates to a pH universal efficient gypsum retarder and a preparation method thereof. The pH universal efficient gypsum retarder provided by the invention comprises an amine compound, bone glue, a reinforcing agent, citric acid, a water reducing agent, a surfactant and water. The amine compound is glycine, the reinforcing agent is ash calcium powder, the water reducing agent is sulfonated melamine formaldehyde resin, and the surfactant comprises tween-80 and sulfonated lignin. The pH universal efficient gypsum retarder prepared by the invention is simple in preparation method, the used raw materials are easy to obtain, the citric acid, the bone glue and the amine compound are used as main retarding components, and different components play different roles; the synergistic effect is achieved in the aspects of reducing the cost, relieving the influence of the pH value, increasing the application scene, reducing the strength redu
