| titleOfInvention | The method for preparing sustained-release polycarboxylic water reducer based on atom transfer radical polymerization |
| abstract | The present invention relates to a kind of methods for preparing sustained-release polycarboxylic water reducer based on atom transfer radical polymerization.The present invention first carries out atom transfer radical polymerization to unsaturated acyl amine minor comonomer using halogenated compound initiator and prepares polymeric monomer initiator, causes esters of unsaturated carboxylic acids and salt unsaturated carboxylic acid minor comonomer by polymeric monomer initiator under the action of catalyst and ligand and unsaturated polyether polymeric monomer carries out atom transfer radical polymerization and is made.Present invention process is reasonable, easy to operate, preparation cost is low, environment friendly and pollution-free, and there is slow release effect using mobility of the sustained-release polycarboxylic water reducer of the invention preparation to concrete, the loss of concrete slump caused by transporting because of long-time can be effectively prevented.The polycarboxylate water-reducer of this method preparation also has the advantages that controllable molecular weight, narrow molecular weight distribution, molecular structure are programmable, has biggish application potential. |
