| titleOfInvention | A kind of special polycarboxylate water reducer for machine-made sand and preparation method thereof |
| abstract | The invention discloses a special polycarboxylate water reducer for machine-made sand and a preparation method thereof. This special polycarboxylate water reducer for machine-made sand is obtained by polymerization of polyether macromonomer, dopamine-modified polyether macromonomer, unsaturated carboxylic acid, unsaturated carboxylate, and dopamine monomer. The invention effectively enhances the adhesion ability of water reducer molecules to the cleavage surface of machine-made sand with low surface energy by introducing the most effective functional group catechol group for mussel protein adhesion into the polymer structure, so that the Slurry can reduce viscosity and thicken, achieve the purpose of reducing bleeding and slurry, and effectively improving the workability and uniformity of concrete mixture. And because the catechol group can also form good coordination and hydrogen bond interaction on the surface of the sand and gravel, it can effectively improve the overall uniformity of the mixture and the mechanical properties and durability after molding. |
