| titleOfInvention | A kind of preparation technology of antifreeze concrete additive and its equipment |
| abstract | The invention discloses a preparation process and equipment of an antifreeze concrete additive. The preparation process includes the following steps: S1. Mixing N-methylpyrrolidone, sodium nitrate, ethylene glycol, surfactant and deionized water to obtain an antifreeze component S2, mix triethanolamine, sodium sulfate and sodium nitrite in proportion to obtain early strength components; S3, react diethanolamine, succinic anhydride, glycerol and rosin resin acid to obtain air-entraining components; S4 , the water-reducing component is obtained by reacting with sodium formaldehyde sulfoxylate, 3-mercaptopropionic acid, acrylic acid, prenyl alcohol polyoxyethylene ether, ammonium persulfate and deionization; S5, mixing the above-mentioned components in proportion Evenly, the antifreeze concrete additive is obtained. The antifreeze concrete additive prepared by the process of the present invention can effectively improve the antifreeze performance of concrete. |
