| titleOfInvention | A kind of polycarboxylate water reducer for prefabricated concrete structure and preparation method thereof |
| abstract | The invention discloses a polycarboxylate water reducer for assembled concrete structures and a preparation method thereof. Its molecular structure contains amino ethyl ester groups, which react in the concrete mixture to form carboxylate ions and amine compounds. The preparation method of the polycarboxylate water reducer is as follows: it is obtained by radical copolymerization reaction of amino ethyl ester monomers, carboxylic acid monomers, amine monomers and polyether monomers in aqueous solution. The initiator of the free radical copolymerization reaction is a water-soluble redox system initiator, including L-ascorbic acid/hydrogen peroxide system and ammonium persulfate/sodium bisulfite system; water-soluble chain transfer agents include mercaptoacetic acid and mercaptopropionic acid More than one of them, and mixed in any proportion. The polycarboxylate superplasticizer can ensure that the concrete mixture has excellent workability retention ability in a short period of time (1h), and enhances the early strength of hardened concrete. At the same time, it has a strong ability to disperse cement and has significant application value. . |
