Water-soluble star-comb polymer concrete viscosity reducer and preparation method thereof
The invention discloses a water-soluble star-comb polymer concrete viscosity reducer and a preparation method thereof, and belongs to the field of concrete. The water-soluble star-comb type polymer concrete viscosity reducer is prepared from the following raw materials in percentage by mass: 20 percent to 40 percent of a monomer, 0.05 percent to 0.80 percent of an initiator PEO-Br3, 0.01 percent to 0.20 percent of a catalyst, 0.05 percent to 0.25 percent of a ligand, 0.001 percent to 0.01 percent of an inactivating agent and the balance of water. The water-soluble star-comb polymer concrete viscosity reducer provided by the invention has the advantages of large steric hindrance, many active sites, low viscosity and excellent viscosity reduction performance.
本发明公开了一种水溶性星型‑梳型聚合物混凝土降粘剂及其制备方法，属于混凝土领域。所述水溶性星型‑梳型聚合物混凝土降粘剂的制备原料以质量百分比计，包括：单体20%‑40%，引发剂PEO‑Br3 0.05%‑0.80%，催化剂0.01%‑0.20%，配体0.05%‑0.25%，失活剂0.001%‑0.01%，余量为水。本发明提供的水溶性星型‑梳型聚合物混凝土降粘剂空间位阻大、活性位点多、粘度低，降粘性能优异。
