Description

Technical Field

[0001] The utility model belongs to the technical field of water reducing agent production, in particular to low-temperature production equipment for polycarboxylic acid water reducing agent. Background Art

[0002] Polycarboxylate water reducer is a high-performance water reducer with advantages such as high water reduction rate, good dispersibility, low dosage, excellent slump retention, low concrete shrinkage, strong molecular structure adjustability, and high-performance potential. It is widely used in highways, bridges, tunnels, high-rise buildings and other projects. In recent years, in my country's rapidly developing construction industry, polycarboxylate water reducer has received huge demand and development.

[0003] The macromonomers used in the synthesis of polycarboxylic acid water reducers are mainly vinyl alcohols and vinyl ethers. The polymerization reaction of vinyl alcohols requires a relatively high temperature. For example, the reaction temperature of three-carbon monomers is 60-70°C, and the reaction temperature of four-carbon and five-carbon monomers is usually 30-40°C. Vinyl ether monomers mainly refer to six-carbon monomers. This type of monomer has high polymerization activity, and the polymerization reaction can be completed at room temperature above 5°C. The production process does not require heating, and the reaction time is greatly shortened. The six-carbon polycarboxylic acid water reducer belongs to a low-temperature process, which not only requires the control of the initial reaction temperature, but also the strict control of the temperature during the polymerization process. However, conventional polycarboxylic acid water reducer production equipment uses normal temperature water for cooling to control the temperature of the monomer, which cannot achieve low-temperature production, resulting in poor performance of the produced polycarboxylic acid mother liquor product, which cannot meet actual production needs.
