Abstract
Disclosed are a highly adaptable viscosity-reducing polycarboxylate water reducer and its preparation method and application. The highly adaptable viscosity-reducing polycarboxylate water reducer is composed of a polymer and water, and the polymer accounts for 30-50 wt %; since the main chain of the polymer contains a hydrophobic benzene ring and hydrophilic amine, the polymer has strong rigidity and good solubility in an aqueous solution, and is rich in two adsorption groups of carboxyl group/phosphono group. The highly adaptable viscosity-reducing polycarboxylate water reducer of the present invention has excellent water-reducing and slump retention properties and is suitable for general construction projects and commercial concrete projects. Compared with the conventional polycarboxylate water reducer, the highly adaptable viscosity-reducing polycarboxylate water reducer of the present invention has strong adaptability to concrete materials and can effectively reduce the viscosity of high-strength concrete (C50-C100), thus having bright application prospects in the high-end water reducer market.
