Organic-inorganic composite intercalated hydrotalcite-based corrosion inhibitor and preparation method and application thereof
The invention relates to an organic-inorganic composite intercalated hydrotalcite-based corrosion inhibitor and a preparation method and application thereof. The organic-inorganic composite intercalated hydrotalcite-based corrosion inhibitor comprises a hydrotalcite compound, vitamin C anions and nitrite, wherein the vitamin C anions and the nitrite respectively replace interlayer anions of the hydrotalcite compound, and the vitamin anions are vitamins without hydrogen ions. The preparation process comprises the following steps of: roasting hydrotalcite, and then respectively carrying out ionexchange reaction with nitrite and vitamin C. And the organic-inorganic composite intercalated hydrotalcite-based corrosion inhibitor is obtained. The corrosion inhibitor disclosed by the invention has a relatively good effect of resisting chloride ion corrosion, and has the advantage of long anti-rust time.
本发明涉及一种有机无机复合插层水滑石基阻锈剂及制备方法及应用。包括水滑石类化合物、维生素C阴离子、亚硝酸根，维生素C阴离子和亚硝酸根分别替换水滑石类化合物的层间阴离子，维生素阴离子为失去氢离子的维生素。制备过程为先将水滑石进行焙烧，然后分别与亚硝酸根、维生素C进行离子交换反应。得到有机无机复合插层水滑石基阻锈剂。本发明的阻锈剂具有较好的抗氯离子侵蚀的作用，同时具有抗锈时间长的优点。
