| titleOfInvention | Preparation method of air-entraining type ester polycarboxylate superplasticizer |
| abstract | The invention discloses a preparation method of an air-entraining type ester polycarboxylate superplasticizer, which comprises the following steps: (1) preparing an esterification product; (2) carrying out copolymerization reaction; (3) and (4) neutralizing. The preparation method of the invention prepares the esterification product by esterifying the coconut diethanolamide and the unsaturated acid, and has the advantages of low cost and simple and convenient operation, and the prepared esterification product participates in the next copolymerization reaction to ensure that the main chain of the polycarboxylate water reducer has hydrophilic groups such as amide, and the prepared polycarboxylate water reducer has better air entraining and foam stabilizing properties, and improves the workability and strength of concrete. |
