Unsaturated polyether ester monomer, polycarboxylate superplasticizer and preparation method of unsaturated polyether ester monomer and polycarboxylate superplasticizer

The invention discloses an unsaturated polyether ester monomer and a preparation method thereof, a polycarboxylate superplasticizer obtained by copolymerization of the unsaturated polyether ester monomer and unsaturated carboxylic acid and a preparation method of the polycarboxylate superplasticizer. The unsaturated polyether ester monomer provided by the invention has a structure shown in the following formula. The unsaturated polyether ester monomer disclosed by the invention does not need a polymerization inhibitor, so that the production risk is reduced, and the polycarboxylic acid water reducer prepared from the unsaturated polyether ester monomer can well solve the problems of neutrality and slump loss resistance of concrete. # imgabs0 # 公开了一种不饱和聚醚酯单体及其制备方法、由所述不饱和聚醚单体与不饱和羧酸共聚得到的聚羧酸减水剂及其制备方法。本发明的不饱和聚醚酯单体具有下式所示结构。本发明的不饱和聚醚酯单体不需要阻聚剂，降低了生产风险，通过该不饱和聚醚酯单体得到的聚羧酸减水剂可以很好地解决混凝土中和易性、保坍性问题。#imgabs0#
