抗泥型聚羧酸减水剂的合成及性能研究

Study on the Synthesis and Performance of Anti-mud Polycarboxylate Superplasticizer

以4-羟丁基乙烯基聚醚与丙烯酸、封端酰胺磷酸酯聚合而成一种抗泥型聚羧酸减水剂,该减水剂能有效降低泥土对聚羧酸减水剂的负面影响,对含泥量不同的砂浆、混凝土都具有很好的分散性和分散保持能力。

In this paper, a new anti-mud polycarboxylate superplasticizer was prepared by monomer such as 4-hydroxyl vinyl butyl polyether, acrylic acid and terminated arnide phosphate. The polycarboxylate superplasticizer can effectively reduce the negative effects of mud on polycarboxylic acid superplasticizer, and has good dispersibility and dispersion holding capacity for mortar/concrete with different mud content.
