Preparation method for synthesizing water reducing agent by adopting six-carbon monomer

The invention relates to the technical field of concrete admixtures, and provides a preparation method for synthesizing a water reducing agent by adopting a six-carbon monomer. The water reducing agent synthesized from the six-carbon monomers comprises a component A, a component B, a component C and a component D. The component A comprises 35-37 parts of unsaturated polyether macromonomers, 0.5-1.5 parts of unsaturated phosphate, 30-32 parts of water, 0.25-0.27 part of hydrogen peroxide, 0.04-0.06 part of ferrous sulfate and 0.45-0.5 part of sodium hypophosphite, the component B comprises 2-3 parts of acrylic acid and 7-8 parts of water, and the component C comprises 0.7-0.9 part of hydroxyethyl acrylate, 0.07-0.09 part of vitamin C and 6-8 parts of water. The component D is prepared from 14 to 16 parts of water and 1.4 to 1.7 parts of sodium hydroxide. According to the technical scheme, the problems that in the prior art, a preparation process of a water reducing agent for concrete is complex, and a prepared
