Slump loss-resistant modified maltodextrin high efficiency water reducer and preparation method thereof
The invention provides a slump loss-resistant modified maltodextrin high efficiency water reducer and a preparation method thereof. A carboxylic group and a phosphate group are introduced to the maltodextrin macro-molecule. Through use of the two groups, product slump loss resistance is substantially improved and a product water reducing effect is improved. The slump loss-resistant modified maltodextrin high efficiency water reducer utilizes cheap raw materials, has reproducibility, does not produce environmental pollution and has sustainability and environmental friendliness. The slump loss-resistant modified maltodextrin high efficiency water reducer obtained by the one-step reaction process has the advantages of simple operation processes and good product water solubility.
