Polycarboxylate superplasticizer mother liquor and preparation method thereof
The invention discloses a polycarboxylate superplasticizer mother liquor and a preparation method thereof. The polycarboxylate superplasticizer mother liquor comprises the following components in parts by weight: 30-34 parts of ether macromonomer; 0.2 to 0.3 part of an oxidizing agent; 3.5 to 4.0 parts of acrylic acid; 0.8 to 1.2 parts of acrylic acid isomeric ester; 0.8 to 1.2 parts of a reducing agent; and 58-62 parts of water. The polycarboxylate superplasticizer mother liquor composed of the ether macromonomer, the oxidizing agent, the acrylic acid, the acrylic acid isoester, the reducing agent and the water has the advantages of high water-reducing rate, good slump retaining performance and good workability.
本发明公开了一种聚羧酸减水剂母液及其制备方法，包括如下按重量份计算的组分：醚类大单体30～34份；氧化剂0.2～0.3份；丙烯酸3.5～4.0份；丙烯酸异构酯0.8～1.2份；还原剂0.8～1.2份；水58～62份。本发明通过醚类大单体、氧化剂、丙烯酸、丙烯酸异构酯、还原剂和水组成的聚羧酸减水剂母液具有减水率高、保坍性能好、和易性好。
