Anti-carbonization concrete reinforcing agent and preparation method thereof
The invention relates to an anti-carbonization concrete reinforcing agent and a preparation method thereof. The structural formula of the anti-carbonization concrete reinforcing agent is as follows: R: C2-C6. The preparation method comprises the following steps: adding alkylamine and an ethanol solution into a reaction kettle, stirring and dissolving at a low speed at room temperature, then heating to 40-50 DEG C, dropwise adding an O-methylisourea sulfate aqueous solution, controlling the dropwise adding to be completed within 30-35 minutes, keeping the temperature to be 40-50 DEG C, reacting for 3-4 hours, cooling to room temperature after the reaction is completed, then adding a defoaming agent, and uniformly stirring, thereby obtaining the anti-carbonization concrete reinforcing agent. The concrete strength is improved, the carbonization resistance of the concrete is improved, the durability of a concrete structure is enhanced, and the service life of the concrete is prolonged.
一种抗碳化混凝土增强剂及其制备方法,所述抗碳化混凝土增强剂的结构式如下:R:C2‑C6。制备方法:在反应釜内加入烷基胺、乙醇溶液低速度室温搅拌溶解,然后升温至40‑50℃并滴加O‑甲基异脲硫酸盐水溶液,控制在30~35分钟滴加完成,保持温度40‑50℃反应3‑4小时,反应完成后冷却至室温,然后加入消泡剂搅拌均匀即得。本发明提高了混凝土强度,提高了混凝土的抗碳化性能,增强了混凝土结构的耐久性能,延长了混凝土的使用寿命。
