| titleOfInvention | A kind of polycarboxylate water reducer for permeable concrete and preparation method thereof |
| abstract | The invention provides a polycarboxylate water reducer for permeable concrete and a preparation method thereof. The polycarboxylate water reducer comprises the following components by weight except water: polyether macromonomer: 345-350 parts, sodium hypophosphite: 3.0-6.0 parts, hydrogen peroxide: 0.5-3.5 parts, persulfuric acid Ammonium: 1.0~2.0 parts, initiator: 100.2~120.8 parts, small monomer solution: 99~135 parts, silane coupling agent without double bond: 0.2~0.5 parts, industrial liquid alkali: 10~25 parts, monoalkane Oxypyrophosphate type coupling agent: 0.2~0.5 parts; among them: the initiator is composed of 0.2~0.8 parts of carbodiimide crosslinking agent and 100~120 parts of water, and the small monomer solution is composed of 39~45 parts of fluorinated Composed of functional monomers and 60-90 parts of water. The present invention introduces new hydrophilic groups, builds a hydrophilic solvent layer from hydrophilic small monomers and reducing agents, and additionally compound silane coupling agents and monoalkoxy pyrophosphate coupling agents to improve Molecular adsorption capacity of superplasticizer and cohesion of cement-based cementitious material slurry. |
