Viscosity reduction type water reducer and preparation method thereof
The invention relates to a viscosity reduction type water reducing agent and a preparation method thereof, and the viscosity reduction type water reducing agent is prepared from the following raw materials in parts by weight: 90-150 parts of sulfonic group end-capped polyether monomer; 90 to 150 parts of a polyether monomer; 4-8 parts of a rheological functional monomer; 4-8 parts of saturated amide; 20 to 32 parts of unsaturated acid; 3 to 6 parts of first unsaturated ester; 1.5 to 3.0 parts of an oxidizing agent; 0.2 to 0.4 part of a reducing agent; 0.8 to 1.5 parts of a chain transfer agent; and 300 to 500 parts of water. The prepared viscosity-reducing water reducer has good viscosity-reducing performance, can improve the workability and flow velocity of concrete, obviously improves the mechanical properties, has no adverse effect, and is wide in adaptability, quick to prepare and high in efficiency.
