Viscosity reduction type polycarboxylate superplasticizer mother liquor and preparation method and application thereof
The invention provides a viscosity reduction type polycarboxylate superplasticizer mother liquor and a preparation method and application thereof. The viscosity reduction type polycarboxylate superplasticizer mother liquor is prepared from the following components in percentage by mass: 34 to 36 percent of a macromonomer, 0.1 to 0.2 percent of an oxidant, 3 to 5 percent of acrylic acid, 5 to 7 percent of hydroxypropyl acrylate, 0.2 to 0.5 percent of mercaptopropionic acid, 0.02 to 0.06 percent of vitamin C and the balance of water, wherein after the macromonomer is dissolved in water, an oxidizing agent is added and mixed to form a base material, acrylic acid, hydroxypropyl acrylate and water are mixed to form a material A, mercaptopropionic acid, vitamin C and water are mixed to form a material B, and during use, the material A and the material B are dropwise added into the base material. The viscosity reduction type polycarboxylate superplasticizer mother liquor which can reduce theviscosity of concrete and is low in cost and is prepared by the formula is convenient to use, excellent in comprehensive performance and low in production energy consumption.
本发明提供一种降粘型聚羧酸减水剂母液及其制备方法和应用,该降粘型聚羧酸减水剂母液,以质量百分比计,包括34‑36%的大单体、0.1‑0.2%的氧化剂、3‑5%的丙烯酸、5‑7%的丙烯酸羟丙酯、0.2‑0.5%的巯基丙酸、0.02‑0.06%的维生素C,余量为水;其中,大单体溶于水后加入氧化剂混合形成底料,丙烯酸、丙烯酸羟丙酯和水混合形成A料,巯基丙酸、维生素C和水混合形成B料;在使用时,将所述A料和B料滴加到所述底料中。以此为配方制得能降低混凝土粘度且成本低的降粘型聚羧酸减水剂母液,使用方便、综合性能优良且生产能耗低。
