Description

Technical Field

[0001] The present invention relates to the field of rust inhibitors, and specifically, to an iron rust inhibitor composition, a preparation method thereof, and an application thereof. Background Art

[0002] Iron and its alloys are widely used in industrial production. However, due to their easy reaction with oxygen and moisture in the air, rusting occurs, affecting their service life and performance. Traditional rust prevention methods such as oil coating and painting have problems such as poor environmental protection and non-persistent rust prevention effects. Traditional rust inhibitors often contain toxic components such as volatile organic compounds and heavy metals, which are harmful to the environment and human body, and some components are difficult to decompose naturally, and the rust prevention effect lasts for a short time, with poor applicability and unstable effects under different metals and environmental conditions.

[0003] Therefore, developing an environmentally friendly, efficient, and persistent iron rust inhibitor is an urgent problem to be solved in the present invention. Summary of the Invention

After cooling to room temperature, the iron rust inhibitor composition is obtained.

[0011] The present invention also provides an application of the iron rust inhibitor composition as described above. The application method includes: uniformly coating the iron rust inhibitor composition on the surface of an iron product to form a thin film, and after drying, a dense rust-proof film is formed on the surface of the iron product.
