Concrete water-retaining agent and preparation method thereof
The invention provides a concrete water-retaining agent and a preparation method thereof. The concrete water-retaining agent is prepared from the following raw materials in parts by weight: 40 to 60 parts of linear polyacrylamide, 35 to 45 parts of polyoxyethylene alkyl phenyl ether phosphate triethanolamine salt, 15 to 50 parts of dipotassium phosphate, 12 to 25 parts of alkylphenol, 10 to 22 parts of isooctyl thioglycolate, 8 to 12 parts of activating agent and 5 to 10 parts of viscosity modifier. The concrete water-retaining agent disclosed by the invention has good water-retaining property, can obviously improve the viscosity of concrete and reduce the segregation of the concrete, so that fresh concrete has good workability, the bleeding rate of the concrete is reduced, and the concrete water-retaining agent can be widely applied to concrete of various pumping constructions such as buildings, roads, bridges, hydraulic engineering, underground engineering and the like.
本发明提供一种混凝土保水剂及其制备方法，包括以下重量份原料：线性聚丙烯酰胺40‑60份、聚氧乙烯烷基苯醚磷酸酯三乙醇胺盐35‑45份、磷酸氢二钾15‑50份、烷基酚12‑25份、巯基乙酸异辛酯10‑22份、活化剂8‑12份、粘度调节剂5‑10份；本发明的混凝土保水剂具有良好的保水性，能明显提高混凝土的粘度，降低混凝土的离析，使得新拌混凝土具有良好的和易性能，降低混凝土的泌水率，可广泛应用于建筑、道路、桥梁、水工和地下工程等各类泵送施工的混凝土。
