| titleOfInvention | A kind of nanometer anti-sludge slump-preserving polycarboxylate water reducing agent and preparation method thereof |
| abstract | The invention discloses a preparation method of a nanometer slime-resistant slump-preserving polycarboxylate water-reducing agent. The nanometer anti-sludge slump-preserving polycarboxylate water-reducing agent is prepared according to a method comprising the following steps: (1) preparing an anti-sludge cross-linking agent. (2) Polymerization reaction. The present invention obtains a kind of nanometer anti-slime slump-preserving polycarboxylate having a cross-linked structure by using a polymerizable emulsifier having a sulfonate structure, an anti-slime cross-linking agent having a polyether polyol structure and a variety of monomers to carry out emulsion polymerization Acid water reducer. Through the cross-linking and hardening of the nano-micellar structure, the dispersing properties of the water reducing agent molecules can be effectively improved, the slurry can be thickened and viscous, and its anti-mud performance can be enhanced to improve the adaptability to different aggregates and the workability of concrete. . Nano anti-slump slump-preserving polycarboxylate superplasticizer will gradually hydrolyze in the cement slurry. On the one hand, a variety of anti-sludge small molecules are released to make it have long-term anti-sludge properties. The micelles are cracked to release linear polycarboxylic acid molecules, which have a long-term slump retention effect. The water reducing agent can also be used as a conditioner in machine-made sand concrete. |
