| titleOfInvention | Preparation method of block slow-release concrete admixture |
| abstract | The invention discloses a preparation method of a block slow-release concrete admixture. The invention utilizes the water solution free radical copolymerization reaction, adopts unsaturated monomers, initiators, chain transfer agents and the like to prepare the block polymer through two-step synthesis, and has the characteristics of strong operability, easy control of reaction process, low sensitivity to reaction conditions, easy industrial production and the like. Polyether side chains of different types and lengths are introduced into the molecular side chains, so that the spatial configuration and the stretching degree of the concrete admixture in a concrete multiphase system can be regulated and controlled; by introducing hydroxy carboxylate, crosslinking monomer and the like into the molecular main chain, the lubricating effect and the hydrophilic state of particles in a concrete multi-item system can be improved, the slump retention of concrete mixture is improved, the time-dependent loss of concrete is reduced, and the working state of concrete is reasonably regulated. |
