| titleOfInvention | A kind of polycarboxylate water-reducer and application thereof and preparation method |
| abstract | The invention discloses a kind of polycarboxylate water-reducer and application thereof and preparation method.Be made up through polyreaction of the component of following parts by weight: polymeric monomer 100 parts; Minor comonomern * 3.2 ~ 13.2 parts; 0.3 ~ 3 part, oxygenant; Minor comonomern * 4.5 ~ 12.7 parts; Reductive agent 0.14 ~ 2 part; Molecular weight regulator 0.2 ~ 1 part; 72 ~ 190 parts, water.The invention provides a kind of new water reducer and application thereof and preparation method, after contrast experiment detects and proves that water reducer of the present invention and conventional commercial polycarboxylic acids water reducing agent compositional use, the initial dispersion of cement is decreased, but has improvement in various degree to dispersion retention; Use water reducer of the present invention to make the workability of fresh concrete obtain improvement to a certain extent, the slump, divergence retention and concrete crushing strength get a promotion.Water reducer raw materials of the present invention is easy to get, synthesis preparation method safely, stablize controlled, raw material and finished product use cost low, safety and environmental protection. |
