Branched chain type polycarboxylic acid water reducing agent mother liquor and preparation method thereof
The invention discloses a branched chain type polycarboxylic acid water reducing agent mother liquor and a preparation method thereof, and belongs to the technical field of building material additives. The mother liquor of the water reducing agent is prepared from the following raw materials in percentage by weight: 42-47% of unsaturated polyoxyethylene ether, 2.4-4% of unsaturated acetylenic acidand/or an unsaturated acetylenic acid derivative, 3.6-6% of unsaturated olefine acid and/or unsaturated olefine acid derivative, 6%-8% of a chain transfer agent a, 0.09%-0.33% of a chain transfer agent b, 8%-10% of an oxidizing agent a, 0.3%-0.7% of an oxidizing agent b, 8%-10% of a reducing agent a, 0.15%-0.2% of a reducing agent b, 0.8%-2% of a liquid alkali and the balance of water. The branched chain type polycarboxylic acid water reducing agent mother liquor prepared by the method is an aqueous solution, and is convenient to store and transport, stable in performance, easily available inraw materials and simple in process.
本发明公开一种支链型聚羧酸系减水剂母液及其制备方法，属于建筑材料外加剂技术领域。本发明减水剂母液上是由以下百分比含量的原料制备而成：不饱和聚氧乙烯醚42～47％、不饱和炔酸和/或不饱和炔酸衍生物2.4‑4％、不饱和烯酸和/或不饱和烯酸衍生物3.6‑6％、链转移剂a 6‑8％、链转移剂b 0.09～0.33％、氧化剂a 8‑10％、氧化剂b 0.3～0.7％、还原剂a 8‑10％、还原剂b 0.15～0.2％、液碱0.8‑2％，其余为水。本发明方法制备的支链型聚羧酸减水剂母液为水溶液，贮存与运输方便，且性能稳定，原料易得，工艺简单。
