Title
(EN) Multi-element adsorption polycarboxylate superplasticizer as well as preparation method and application thereof
(ZH) 一种多元吸附聚羧酸减水剂及其制备方法和应用
Abstract
(EN)
The invention discloses a multi-element adsorption polycarboxylate superplasticizer, which is composed of 30-60 wt% of macromolecules with multi-element adsorption functional groups and water, whereinthe macromolecule with the multi-element adsorption functional group has a polyethylene glycol side chain, an adsorption group of a polymer main chain of the macromolecule has a carboxylic acid group, a sulfonic acid group and a phosphonic acid group, and the phosphoric acid group is linked to the main chain of the macromolecule with the multi-element adsorption functional group in a nucleophilicaddition mode. Compared with a traditional polycarboxylic acid water reducing agent, the polycarboxylate superplasticizer has the advantages that the adaptability to different cement and aggregates is obviously improved while the high water reducing efficiency is kept, the water reducing efficiency can be well achieved in various different grades of cement, and meanwhile, the tolerance to the aggregates containing more impurities, such as machine-made sand, is good.
