Composite polycarboxylate superplasticizer mother liquor and preparation method and application thereof
The invention provides a composite polycarboxylate superplasticizer mother liquor as well as a preparation method and application thereof. The composite polycarboxylate superplasticizer mother liquoris prepared from the following materials in parts by mass: 31 to 36 parts of macromonomer, 0.4 to 0.6 part of oxidant, 1.8 to 2.8 parts of component a, 2.0 to 2.5 parts of hydroxyethyl acrylate, 1.5 to 2.0 parts of hydroxypropyl acrylate, 0.15 to 0.20 part of component b, 0.06 to 0.10 part of component c and 55.8 to 63.09 parts of water; wherein the component a is acrylic acid and/or methacrylic acid, the component b is one or more of mercaptopropionic acid, mercaptoacetic acid or mercaptoethanol, and the component c is vitamin C and/or sodium formaldehyde sulfoxylate. The composite polycarboxylate superplasticizer mother liquor with high water-reducing rate and low fluidity time loss is prepared according to the formula at normal temperature, so that the product is convenient to use, widein applicability and low in cost.
本发明提供一种复合型聚羧酸减水剂母液及其制备方法和应用，该复合型聚羧酸减水剂母液由以下材料按质量份制成：大单体31‑36份、氧化剂0.4‑0.6份、组分a 1.8‑2.8份、丙烯酸羟乙酯2.0‑2.5份、丙烯酸羟丙酯1.5‑2.0份、组分b 0.15‑0.20份、组分c 0.06‑0.10份和水55.8‑63.09份；其中，组分a为丙烯酸和/或甲基丙烯酸，组分b为巯基丙酸、巯基乙酸或巯基乙醇中的一种或多种，组分c为维生素C和/或甲醛合次硫酸氢钠。以此为配方在常温下制得具备减水率高且流动性经时损失小的复合型聚羧酸减水剂母液，使用方便、适用性广且成本低。
