| titleOfInvention | Polycarboxylate superplasticizer with modified cyclodextrin side chain structure and preparation method thereof |
| abstract | The invention discloses a modified cyclodextrin side chain structure polycarboxylate superplasticizer, which has a general structural formula as follows: wherein a, b, c, d, m and n are polymerization degrees and are positive integers, a is 15-20, b is 1-5, c is 55-90, d is 1-5, m is 45-90, and n is 9-27. The invention also discloses a preparation method of the modified cyclodextrin side chain structure polycarboxylate superplasticizer. The synthesized polycarboxylate superplasticizer has an etherified cyclodextrin side chain structure on the molecule, is more stable in the alkaline environment of concrete compared with an esterified cyclodextrin side chain structure, does not generate hydrolysis reaction, has good stability after being added into the concrete, has excellent water retention, slump retention and tackifying performances, and has small change of net paste fluidity after 120 min. |
