Water-retention coating material for cement concrete surface and preparation method of water-retention coating material
The invention discloses a water-retaining coating material for a cement concrete surface and a preparation method of the water-retaining coating material. The method comprises the following steps: preparing a mixed aqueous solution of sodium alginate and polyvinyl alcohol; mixing the mixed aqueous solution with glycerol and an acrylic emulsion to obtain a concrete curing solution; the concrete surface is coated with the concrete curing liquid; and a calcium chloride solution is sprayed to the surface of the concrete curing liquid on the surface of the concrete, and the water-retaining coating material is formed on the surface of the concrete through reaction. The polymer water-retaining film material can be used in a spraying mode after being prepared into an aqueous solution, and compared with a traditional water-retaining method of laying a plastic film, the polymer water-retaining film material is higher in efficiency, simple to operate and easy to master, and can achieve the effect of rapid, simple and convenient construction.
本发明公开了一种用于水泥混凝土表面的保水覆膜材料及其制备方法，所述方法包括：配制海藻酸钠和聚乙烯醇的混合水溶液；取所述混合水溶液与丙三醇、丙烯酸乳液混合，获取混凝土养护液；将混凝土养护液涂覆到混凝土表面；向所述混凝土表面的混凝土养护液表面喷洒氯化钙溶液，并在所述混凝土表面反应形成保水覆膜材料。本发明所研究的高分子保水覆膜材料在配成水溶液之后可以通过喷洒的方式进行使用，相较传统铺设塑料薄膜的保水方法效率更高，操作简单、易于上手，能够达到施工快速简便的效果。
