| titleOfInvention | A kind of preparation method of anti-mud collapse protection type phosphate ester-containing based polycarboxylic acid water-reducing agent |
| abstract | The invention discloses a kind of preparation method of anti-mud collapse protection type phosphate ester-containing based polycarboxylic acid water-reducing agent, comprise the following steps that：1) preparation of the polycarboxylate water-reducer performed polymer containing halogen：By the unsaturated monomer containing halogen, unsaturated acids minor comonomer, unsaturated polyether polymeric monomer or unsaturated esters polymeric monomer under the action of initiator, reducing agent and chain-transferring agent, carry out redox Raolical polymerizable and obtain the polycarboxylate water-reducer performed polymer containing halogen；2) the polycarboxylate water-reducer performed polymer containing halogen and alkyl phosphate are carried out Arbuzov to react to obtain the copolymerization product of phosphoric acid ester group, adjusts pH value after the completion of reaction, add water to obtain poly carboxylic acid series water reducer.Anti- mud collapse protection type phosphate ester-containing based polycarboxylic acid water-reducing agent prepared by the present invention has the advantages that volume is low, water-reducing rate is high, it is strong to protect the time long and anti-mud that collapses, it can avoid the adverse effect that mud-containing aggregates are brought in concrete, easily controllable and synthesis technique is simple, production cost is low. |
