Abstract

The invention provides a plant-type composite high-efficiency corrosion inhibitor, which is made of the following raw materials in mass percentage: 12-66.0% of plants, 5.0-16.0% of sodium molybdate, 1.5-12% of sodium gluconate, and 3.5-25% of sodium tartrate %, zinc sulfate 0‑23% and potassium dihydrogen phosphate 4.0‑23.0%. The corrosion inhibitor of the invention has strong corrosion inhibition ability, and can exert corrosion inhibition effect on chlorine salt type deicing agent. After adding the corrosion inhibitor, it can reduce the corrosion of the chloride-salt deicing agent to metal and concrete and the damage to the vegetation. The corrosion inhibitor is mainly plant-based, non-toxic, and is a very efficient and environmentally friendly corrosion inhibitor. The invention also provides the preparation method and application of the plant-type composite high-efficiency corrosion inhibitor.

Description

technical field [0001] The invention belongs to the technical field of corrosion inhibitors, in particular to a plant-type composite high-efficiency corrosion inhibitor and a preparation method thereof. Background technique [0002] There are many methods of metal protection, among which the method of protecting metal by corrosion inhibitor has a bright prospect because of its characteristics of less dosage, quick effect, wide source and strong applicability. The types of corrosion inhibitors vary according to the classification methods: according to their physical properties, they can be divided into inorganic corrosion inhibitors and organic corrosion inhibitors; according to the type of medium used, they can be divided into acidic corrosion inhibitors, neutral corrosion inhibitors Corrosion inhibitors and alkaline corrosion inhibitors. The corrosion inhibitors studied earlier were mainly inorganic corrosion inhibitors such as chromate and mercury salts, but with the deve...
