| titleOfInvention | A kind of viscosity-reducing polycarboxylate water-reducing agent containing alkyl group and its preparation method and use |
| abstract | The invention provides a viscosity-reducing type active macromonomer, and the invention also provides a viscosity-reducing type polycarboxylate water-reducing agent. The viscosity-reducing type polycarboxylate water-reducing agent synthesized by the invention has the The functional groups interact synergistically. Compared with the viscosity-reducing polycarboxylate water-reducing agent synthesized in the prior art, the viscosity-reducing effect is superior and the water-reducing rate is not affected. At the same time, a large amount of hydrophobicity is introduced into the PEG side chain. Alkyl, which reduces the HLB value, enhances the surface active effect, and has good shrinkage reduction properties. The concrete mixed with the product of the present invention has low shrinkage rate and no cracking. The viscosity-reducing hydrophobic functional group is located on the side chain, and the viscosity-reducing effect of the water-reducing agent can be adjusted by the content of the viscosity-reducing functional group, but it does not affect the content of the dispersing group, and does not affect the dispersing effect of cement particles, so it does not affect the water-reducing effect. Dispersion and water-reducing effect of the agent. |
