| description | The invention discloses a preparation method for high-dispersity polycarboxylic acid water reducing agents, which consists of two steps: middle macromonomer preparation and polycarboxylic acid finished product preparation. Because a two-step method is adopted, the process is simple, the conditions are easy to control, the performance is stable, organic solvents polluting environment are not used in production, the high-dispersity polycarboxylic acid water reducing agents are environment-protection water-solubility high polymer materials, and the industrial production is easy to realize. In addition, a plurality of units are mainly introduced for carrying out copolymerization reaction, the molecular structure is a comb type structure, polar groups are contained in a main chain, polyoxyethylene base chain sections are contained in a side chain, the space separation is formed, the cement dispersity and the dispersity maintenance capability are favorably improved, and the advantages of low-doping quantity, high d |
