Concrete curing agent and preparation method thereof
The invention provides a concrete curing agent and a preparation method thereof, and solves the technical problems of low effective water retention rate and insufficient compressive strength ratio ofthe concrete curing agent in the prior art. The concrete curing agent comprises the following raw materials in parts by weight: 20 to 30 parts of methyl methacrylate, 30 to 40 parts of styrene, 22 to28 parts of aluminum sulfate, 3 to 7 parts of carboxymethyl cellulose, 10 to 20 parts of an EVA emulsion, 10 to 15 parts of sodium silicate, 0.2 to 0.6 part of lithium carbonate, 0.1 to 0.4 part of triethanolamine, 1 to 3 parts of a coalescing agent, 0.8 to 1.5 parts of a defoaming agent, 1 to 3 parts of a leveling agent, 0.1 to 0.5 part of a plasticizer, and 20 to 28 parts of water. The concretecuring agent provided by the invention can be used after initial setting of concrete in manners of spraying, brush coating or roll coating and the like, has high effective water retention rate and excellent compressive strength ratio, and also has the advantages of low abrasion loss and short drying time.
本发明提供了一种混凝土养护剂及其制备方法，解决了现有技术中的混凝土养护剂有效保水率偏低，并且抗压强度比不够的技术问题。其制备包括下述重量份的原料：甲基丙烯酸甲酯20‑30份；苯乙烯30‑40份；硫酸铝22‑28份；羧甲基纤维素3‑7份；EVA乳液10‑20份；硅酸钠10‑15份；碳酸锂0.2‑0.6份；三乙醇胺0.1‑0.4份；成膜助剂1‑3份；消泡剂0.8‑1.5份；流平剂1‑3份；增塑剂0.1‑0.5份；水20‑28份。本发明提供的混凝土养护剂，可以以喷涂、刷涂或滚涂等方式在混凝土初凝后使用，其具有有效保水率高以及优良的抗压强度比，并且还具有磨耗量低、干燥时间短的优势。
