| titleOfInvention | Preparation method of alkali-free and chlorine-free accelerator with high aluminum content |
| abstract | The invention discloses a preparation method of an alkali-free and chlorine-free accelerator with high aluminum content, which comprises the following steps: the method comprises the following steps: (1) uniformly mixing 2-acrylamide-2-methylpropanesulfonic acid, acrylamide, acrylic acid, sodium hydroxide, an initiator, a cross-linking agent and water to obtain a water phase; mixing cyclohexane and sorbitan oleate to obtain oil phase; heating the oil phase to 50-70 ℃, then dropwise adding the water phase, carrying out polymerization reaction for 5-10 h, and then filtering and drying to obtain a dissolution promoter; (2) uniformly mixing aluminum sulfate, a dissolution promoter and water, standing for 1h, continuously adding alcohol amine, a pH regulator and a rheological agent, heating to 60-80 ℃, reacting for 3-6 h, and cooling to room temperature to obtain the alkali-free and chlorine-free accelerator with high aluminum content. The method adopts the dissolution accelerator to increase the content of aluminum sulfate, and the alkali-free and chlorine-free accelerator prepared by modification can greatly improve the 1d compressive strength of cement mortar and can also improve the comprehensive properties of the product such as stability and the like. |
