Doped imidazoline reinforced concrete corrosion inhibitor and preparation method thereof
The invention discloses a doped imidazoline reinforced concrete corrosion inhibitor and a preparation method thereof. According to the technical scheme, the preparation method comprises the followingsteps: S1, imidazoline preparation: weighing oleic acid and hydroxyethyl ethylenediamine in parts by weight according to a weight ratio of (3.5-4.5):(5-7), mixing the oleic acid and the hydroxyethyl ethylenediamine, and performing reacting at a temperature of 220-240 DEG C to generate a mixture until no water is discharged; S2, pH value adjustment: cooling the mixture obtained in the S1, and adjusting the pH value to 5-6 by using a NaOH solution with a mass fraction of 30% at a temperature of 40-60 DEG C to generate an imidazoline monomer; and S3, imidazoline corrosion inhibitor preparation: the imidazoline corrosion inhibitor comprises the following components in percentage by weight: 15%-25% of imidazoline, 5%-15% of an emulsifier, 2%-8% of a solvent and 60%-70% of water, so that the effect of reducing corrosion of corrosive substances to steel bars is achieved.
本发明公开了一种掺入型咪唑啉钢筋混凝土阻锈剂及其制备方法，其技术方案要点是包括如下步骤：S1：咪唑啉制备，按重量份数称取油酸和羟乙基乙二胺，油酸与羟乙基乙二胺的重量比3.5‑4.5：5‑7，将油酸和羟乙基乙二胺混合，在温度为220℃‑240℃的条件下进行反应生成混合物，直到不出水为止；S2：调pH，对S1中的混合物进行降温，在温度为40℃‑60℃的条件下，用质量分数30%的NaOH溶液调节pH至5～6,生成咪唑啉单体；S3：咪唑啉阻锈剂配制，咪唑啉阻锈剂按重量百分比包括咪唑啉15%‑25%、乳化剂5%‑15%、溶剂2%‑8%、水60%‑70%，达到减少侵蚀性物质对钢筋腐蚀的效果。
