Polycarboxylate superplasticizer for recycled aggregate concrete and preparation method thereof
The invention discloses a polycarboxylate superplasticizer for recycled aggregate concrete and a preparation method of the polycarboxylate superplasticizer. The polycarboxylate superplasticizer comprises a polyester macromonomer, acrylic acid, acrylamide, methacryloyl morpholine, alkyl acrylate phosphate, sodium dodecyl benzene sulfonate, sulfonated melamine, hydroxyethylidene diphosphonic acid, glycerol, a chain transfer agent, an initiator, a neutralizer and water. The technical problems that recycled aggregate concrete commonly used in the existing concrete industry is high in adsorbability to additives, poor in slump retaining capacity, short in setting time and the like are solved.
本发明公开了一种用于再生骨料混凝土的聚羧酸减水剂及其制备方法，包括:聚酯大单体、丙烯酸、丙烯酰铵、甲基丙烯酰吗啉、烷基丙烯酸酯磷酸酯、十二烷基苯磺酸钠、磺化三聚氰胺、羟基乙叉二磷酸、丙三醇、链转移剂、引发剂、中和剂以及水，本发明解决了现有混凝土行业中常用的再生骨料混凝土对外加剂吸附性较大，保坍能力差，凝结时间短等技术问题。
