The invention discloses a polycarboxylic acid water reducing agent and a preparation method thereof; the water reducing agent is synthesized by adopting an A material, a B material and a C material, wherein the A material is composed of a reducing agent, a chain transfer agent and softened water, the B material is composed of an unsaturated monocarboxylic acid and a derivative monomer thereof and softened water, and the C material is composed of a macromonomer, an oxidant and softened water. The polycarboxylic acid water reducing agent has the advantages that normal temperature synthesis of the polycarboxylic acid water reducing agent is realized, not only is the energy consumption reduced, but also the side effects are reduced, the performance of the polycarboxylic acid water reducing agent is improved, and the obtained water reducing agent has excellent water reducing effect.
