The Synthesis of Polycarboxylates Water Reducer with Phosphate Structure

Abstract:

This article uses hydroxylethyl acrylate and phosphorylation reagent for esterification reaction, synthesis of a phosphate ester monomer with double bonds, and phosphate ester monomer ,Participation as the third monomer polymerization of acrylic acid and isoprene polyoxyethylene ether (TPEG). Polycarboxylate was synthesized with phosphoric acid ester structure,Investigate the impact of Phosphate ester content in single and double to polycarboxylate performance. The results showed that the polycarboxylate with phosphate structure has excellent adaptability and reduction of water slump performance.
