Acrylic-series water-reducing agent

The invention discloses an acrylic-series water-reducing agent, belonging to the field of chemical engineering. The acrylic-series water-reducing agent is prepared from the following raw materials by weight: 20 to 40 parts of acrylic acid, 6 to 10 parts of methyl acrylate, 15 to 35 parts of methacrylic acid, 5 to 9 parts of methyl methacrylate, 0.01 to 0.03 part of benzoyl peroxide, 0.03 to 0.05 part of n-dodecanethiol and 60 to 80 parts of absolute ethyl alcohol. A synthesis process for the acrylic-series water-reducing agent is simple and has low requirements on raw materials and equipment; and the synthesized acrylic-series water-reducing agent has greatly improved concrete dispersion performance.
