Mud-resistant slump-retaining polycarboxylic acid water reducer mother liquor and preparation method thereof
The invention discloses a mud-resistant slump-retaining polycarboxylic acid water reducer mother liquor and a preparation method thereof, and belongs to the technical field of building material admixtures. The water reducer mother liquor solves the problem of compatibility between the water reducer mother liquor and cement, and comprises 300-400 parts of unsaturated polyoxyethylene ether, 15-25 parts of unsaturated carboxylic acid, 30-50 parts of unsaturated carboxylic ester, 5-10 parts of 2-hydroxyethyl methacrylate phosphate, 2-5 parts of a chain transfer agent, 2-4 parts of an oxidizing agent, 1-2 parts of a reducing agent, 2-8 parts of liquid caustic soda and 400-500 parts of deionized water. The mud-resistant slump-retaining polycarboxylic acid water reducer mother liquor can be used as a cement water reducer.
本发明公开了一种抗泥保坍型聚羧酸减水剂母液及其制备方法，属于建筑材料外加剂技术领域。解决了减水剂母液与水泥的相容性问题，其包括不饱和聚氧乙烯醚300‑400份、不饱和羧酸15‑25份、不饱和羧酸酯30‑50份、2‑羟乙基甲基丙烯酸酯磷酸酯5‑10份、链转移剂2‑5份、氧化剂2‑4份、还原剂1‑2份、液碱2‑8份、去离子水400‑500份。本发明可用作水泥减水剂。
