Abstract

This invention relates to a pollution-free rust-preventive oil and its preparation method, belonging to the technical field of rust-preventive oils. This invention uses No. 10 machine oil as a carrier, allowing other functional additives to be uniformly dispersed in the oil. Rust inhibitors such as barium petroleum sulfonate, sodium petroleum sulfonate, and zinc naphthenate can form a protective film on the metal surface, collectively enhancing the rust-preventive effect. Benzotriazole, as a corrosion inhibitor, can form a dense passivation film on the metal surface, working synergistically with the rust inhibitors. Sodium dodecyl sulfonate has excellent dispersing and emulsifying properties, helping other additives to be better dispersed in the base oil. Furthermore, sodium dodecyl sulfonate can enhance the rust-preventive film. 3-Mercaptopropyltrimethoxysilane can enhance the adhesion and water resistance of the rust-preventive film, improving the overall performance of the rust-preventive oil. The addition of modified lanolin can improve the stability of the rust-preventive oil, enabling it to maintain good rust-preventive effects under various environmental conditions.
