| titleOfInvention | Organic-inorganic hybrid polycarboxylate superplasticizer and preparation method thereof |
| abstract | The invention discloses an organic-inorganic hybrid polycarboxylate superplasticizer which has a general structural formula as follows: wherein R is 1 Is H or-CH 3 ，R 2 is-CH 2 -or-COOCH 2 CH 2 CH 2 And a, b, c, d, m and n are polymerization degrees and are positive integers, wherein a is 5-12, b is 1-5, c is 40-80, d is 1-3, m is 135-225, and n is 40-55. The invention also discloses a preparation method of the organic-inorganic hybrid polycarboxylate superplasticizer. Compared with pure organic polycarboxylic acid molecules, the polycarboxylic acid water reducer synthesized by the invention has the characteristics of an organic polycarboxylic acid water reducer and the size effect of inorganic particles, and comprises the following steps: steric hindrance, "rolling ball" and "filling" effects; after the concrete is added, the water retention and slump retention performance is good, and the change of the fluidity of the clear paste is small after 120min, so that the early strength of the concrete is increased. |
