Production Method of High Slump Retaining Type Polycarboxylate Superplasticizer：
Preparation of raw materials: The primary raw materials of high-slump retention polycarboxylate superplasticizer include polycarboxylate, initiator, crosslinking agent, catalyst, solvent, etc. Polycarboxylate is the critical component, which can be polymerized from methacrylate, acrylic ester, styrene and other monomers. Initiators, crosslinking agents, catalysts, etc., control the polymerization process and the properties of the products.

Polymerization reaction: the polycarboxylate monomer, initiator, crosslinking agent, catalyst, etc., are mixed at a specific temperature and pressure polymerization reaction. Polycarboxylic acid esters with specific molecular weight and molecular weight distribution can be obtained by controlling reaction conditions and monomer concentration.

Separation and purification: After the polymerization reaction, the product is separated and purified to remove unreacted raw materials and impurities. In this step, pure polycarboxylate can be obtained by precipitation, filtration, centrifugal separation and other methods.

Adding auxiliary agent: Polycarboxylate can be modified or added as an auxiliary agent to improve the performance and application effect of the reducing agent. Standard modification methods include grafting, blocking, crosslinking, etc., which can introduce new functional groups or improve polymer properties. The auxiliary agent includes a dispersant, stabilizer, wetting agent, etc., which can enhance the compatibility and application effect of water-reducing agent and concrete.

Drying and packaging: the polycarboxylate solution is dried, and the water is removed to obtain a high slump retention polycarboxylate superplasticizer in solid form. Finally, the finished water-reducing agent is obtained by packaging.
