| titleOfInvention | Alkali-free liquid accelerator adopting electrolytic method and preparation method thereof |
| abstract | The invention provides an alkali-free liquid accelerator adopting an electrolytic method, which comprises the following components in percentage by mass: aluminum alloy: 2-3%, aluminum sulfate: 40-45%, magnesium fluosilicate: 6-8%, hydrofluoric acid: 2-4%, reinforcing components: 7-10%, alcohol amine: 0.1-0.5%, and the balance of water, which accounts for 100%; the invention also provides a preparation method of the alkali-free liquid accelerator, which comprises the following steps: (1) preparing an electrolyte; (2) preparing aluminum hydroxide gel; (3) preparing polyaluminium sulfate; (4) preparing an alkali-free liquid accelerator; the invention adopts electrolytic method to prepare polymeric aluminum sulfate type liquid alkali-free accelerator, without alkalizer, and takes aluminum alloy as anode, electrifys to oxidize the aluminum alloy to generate aluminum hydroxide gel, and reacts with aluminum sulfate in the solution to generate polymeric aluminum sulfate solution. Compared with other similar products in the market, the product has good adaptability to different types of cement and good product stability, is an alkali-free liquid accelerator with superior performance, and can be widely applied to projects such as tunnels, bridges, rush repairs and the like. |
