| titleOfInvention | Wet-mixed mortar plasticity stabilizer and preparation method thereof |
| abstract | The invention relates to the technical field of building additives, in particular to a wet-mixed mortar plasticity stabilizer and a preparation method thereof, wherein the preparation method comprises the following steps: mixing 4-hydroxybutyl vinyl polyoxyethylene ether monomer, acrylic acid, methacryloyloxyethyl succinate monoester and water, and adding hydrogen peroxide; after the reaction, adding an aqueous solution of a reducing agent, an aqueous solution of a cocatalyst and an aqueous solution consisting of acrylic acid, 2-amino-3-p-hydroxyphenyl propionate, 3-hydroxyphenyl phosphoryl propionic acid dihydromyrcenol ester and a chain transfer agent in sequence; and after the reaction is finished, adding polyvinyl alcohol, and adjusting the pH value to 7-8 to obtain the wet-mixed mortar plasticity stabilizer. Compared with the prior art, the mortar synthesized by the wet-mixed mortar plasticity stabilizer provided by the invention has the advantages of low consistency loss, good water retention rate, high mortar compressive strength and long-term stability and the like, and has remarkable progress. |
