Environment-friendly polycarboxylate superplasticizer and synthesis process thereof
The invention discloses an environment-friendly polycarboxylate superplasticizer and a synthesis process thereof. The water reducing agent is prepared from polyethylene glycol, metacrylic acid ester, cross-linked modified acrylic acid, deionized water, an initiator, a reducing agent, a pH regulator, a catalyst and the like according to a certain mass percentage. The method has the main characteristics of environmental protection and high efficiency, and the performance is improved by introducing cross-linked modified acrylic acid and optimizing the acid-alcohol ratio. The synthesis method comprises the following specific synthesis steps: dissolving raw materials, mixing monomers, dissolving an initiator and a reducing agent, carrying out a reaction, adding a catalyst, finishing the reaction and purifying a product. The water reducing agent has an excellent water reducing effect and good stability, and is suitable for various construction environments. Meanwhile, environment-friendly raw materials and processes are adopted, the whole production process meets the requirements of green chemical engineering, and environmental pollution is reduced.
