[0002] Polycarboxylate water reducer is a high-performance water reducer and a cement dispersant used in cement concrete. It is widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. Polycarboxylate water reducer is synthesized by copolymerization of unsaturated monomers in the synthesis process. Therefore, there are many synthetic liquid raw materials for this type of water reducer, usually polyethylene glycol, methacrylic acid, propylene glycol and polyoxyethylene ether. These liquid raw materials are mixed and reacted inside the reactor to form polycarboxylate water reducer.
