| titleOfInvention | A kind of ultra-early strength type fluorine-free alkali-free liquid accelerator and preparation method thereof |
| abstract | A super early-strength type fluorine-free and alkali-free liquid accelerator and a preparation method thereof, wherein the accelerator is prepared from the following raw materials: aluminum sulfate, organic accelerator, stabilizer, early-strength agent, pH regulator, water . The organic accelerator is composed of three components A, B and C. A is monoethanolamine, diethanolamine, triethanolamine, and B is N-methyldiethanolamine, N,N-dimethylethanolamine, N,N -Dimethylformamide, C is diethylenetriamine, triethylenetetramine, tetrahydroxypropylethylenediamine; stabilizer is ultrafine sepiolite, pseudo-boehmite; pH regulator is p-toluenesulfonic acid , oxalic acid, formic acid; early strength agents are lithium sulfate, magnesium sulfate, nano-silica sol, nano-aluminum sol. The invention has good performance, simple preparation process, no fluorine, no alkali and no chlorine, and at the same time meets the performance requirements of each standard for the alkali-free accelerator, the 6-hour compressive strength is far greater than 2.5MPa, and the 1-day compressive strength The strength is far greater than 15.0MPa, the 90-day compressive strength retention rate is ≥110%, and the stability is more than 9 months. |
