Concrete curing agent for bridge and preparation method thereof
The invention relates to a concrete curing agent for bridges and a preparation method thereof in the technical field of concrete curing. The concrete curing agent is prepared from the following raw material components in parts by weight: 100 to 250 parts of polyvinyl alcohol resin, 180 to 300 parts of sodium silicate, 100 to 200 parts of N-carboxybutyl chitosan, 20 to 70 parts of a coalescing agent, 30 to 60 parts of a surfactant, 10 to 30 parts of a defoaming agent, 20 to 50 parts of a flatting agent and 600 to 900 parts of water. The polyvinyl alcohol resin, the sodium silicate and the N-carboxybutyl chitosan are compounded for use, so that the curing agent not only can form a moisturizing film on the surface of concrete, but also can block pores in the surface layer of the concrete, water in the concrete is effectively prevented from being evaporated, the cracking phenomenon of the concrete is reduced, and the service life of the concrete is prolonged. The strength of the concrete is guaranteed, and the concrete can be well applied to concrete for bridges and has a good market prospect.
本申请涉及混凝土养护技术领域的一种桥梁用混凝土养护剂及其制备方法。按重量份计，所述混凝土养护剂的制备原料包括以下成分：聚乙烯醇树脂100‑250份、硅酸钠180‑300份、N‑羧丁基壳聚糖100‑200份、成膜助剂20‑70份、表面活性剂30‑60份、消泡剂10‑30份、流平剂20‑50份和水600‑900份。本申请通过将聚乙烯醇树脂、硅酸钠和N‑羧丁基壳聚糖复配使用，使得本申请所述养护剂不仅能在混凝土表面形成保湿薄膜，还能够对混凝土表层的孔隙进行封堵，有效地阻挡了混凝土中的水分蒸发，减少混凝土出现龟裂的现象，保证混凝土的强度，能较好地应用在桥梁用混凝土中，具有良好的市场前景。
