| description | The invention belongs to the field of water reducing agents, particularly relates to a comprehensive polycarboxylic acid high-performance water reducing agent synthesized by a low-temperature method and a preparation method thereof, and aims at the characteristic that a concrete admixture needs to adapt to a concrete material along with the change of concrete raw materials in the prior art. In order to solve the problem that the requirements of high-performance concrete on additives are more and more clear, the invention provides the following scheme. The comprehensive polycarboxylic acid high-performance water reducing agent synthesized by the low-temperature method comprises the following raw materials in parts by mass: 30 to 50 parts of EPEG polyether macromonomer (with the molecular weight of 2400 to 3000), 3 to 5 parts of completely esterified isoester (with the molecular weight of 1500 to 3000), 3.3 to 5.5 parts of acrylic acid, 0.3 to 0.5 part of initiator 27.5% hydrogen peroxide, 0.15 to 0.25 part of |
