Preparation method of composite corrosion inhibitor
The invention relates to the technical field of building materials, and particularly discloses a preparation method of a composite corrosion inhibitor. The corrosion inhibitor comprises the following components in percentage by weight: 5%-7% of sodium tetraborate, 3%-5% of sodium sulfamate, 4%-6% of ammonium molybdate, 12%-14% of isobutanol amine, 6%-10% of diethanolisopropanolamine and 58%-70% of water. The preparation method comprises the steps of weighing according to the ratio of the raw materials, firstly adding water into a reaction kettle, heating to the temperature of 50-55 DEG C, starting a stirrer, adding ammonium molybdate into the reaction kettle, dissolving for 10 minutes, then adding sodium tetraborate, adding sodium sulfamate after 10 minutes, accelerating stirring for 10 minutes, turning off a heater, adding isobutanol amine after the temperature is reduced to normal temperature, adding diethanolisopropanolamine after 15 minutes, continuously stirring for half an hour, and stopping stirring so as to obtain the novel composite corrosion inhibitor with the concentration of 30g/L to 42g/L. The composite corrosion inhibitor can effectively prolong the durability of reinforced concrete, and can be widely used in ocean engineering, civil buildings and high saline and alkaline areas.
本申请涉及建筑材料技术领域，具体公开了一种复合型阻锈剂的制备方法，所述阻锈剂组分按重量百分比记为四硼酸钠5％‑7％，氨基磺酸钠3％‑5％，钼酸胺4％‑6％，异丁醇胺12％‑14％，二乙醇单异丙醇胺6％‑10％，水58％‑70％，其制备方法为:按原料配比称量，先将水加入反应釜中，加热至50℃‑55℃，开启搅拌器，将钼酸铵加入反应釜中溶解10min，之后加入四硼酸钠，10min后加入氨基磺酸钠加速搅拌10min，关闭加热器待温度降至常温后加入异丁醇胺，15min后加入二乙醇单异丙醇胺持续搅拌半小时后关闭搅拌，即得到浓度为30g/L至42g/L的新型复合型阻锈剂。本申请中的复合型阻锈剂可有效延长钢筋混凝土的耐久性，在海洋工程、民用建筑、高盐碱地区可广泛使用。
