Green environment-friendly stable alkali-free liquid accelerator and preparation method and application thereof
The invention discloses a green environment-friendly stable alkali-free liquid accelerator and a preparation method and application thereof. The green environment-friendly stable alkali-free liquid accelerator is prepared from the following raw materials: a polyaluminum sulfate solution, an acidic silica sol dispersion liquid, anhydrous sodium sulphate, calcium formate, an early-strength coagulation promoting component, a dispersing agent and water. The preparation method comprises the following steps: (1) mixing and stirring a polyaluminum sulfate solution and an acidic silica sol dispersion liquid to obtain a reaction liquid; and (2) adding anhydrous sodium sulphate, calcium formate, an early-strength coagulation-promoting component and a dispersing agent into the reaction liquid obtained in the step (1), carrying out heat preservation reaction at 40-50 DEG C for 1.5-3 hours, then adding water, and uniformly mixing so as to obtain the environment-friendly stable alkali-free liquid accelerator. The green environment-friendly stable alkali-free liquid accelerator is environment-friendly, good in stability, low in production cost, good in rapid setting effect and simple in preparation method.
