This invention provides a rust-preventive oil for cold-rolled grain-oriented silicon steel sheets and its preparation method, belonging to the field of metal corrosion and protection. The invention uses isooctyl oleate and / or isooctyl stearate as the base oil of the rust-preventive oil. These are low-viscosity synthetic esters, which, compared to mineral oils, exhibit excellent biodegradability under natural environmental conditions and stronger adsorption, wetting, spreading, and penetration on metal surfaces. This allows for the formation of a thicker and stronger oil film on the surface of grain-oriented silicon steel sheets, achieving more long-lasting and stable rust protection. Furthermore, the rust-preventive oil for cold-rolled grain-oriented silicon steel sheets provided by this invention does not contain barium heavy metal salts and has excellent biodegradability, making it extremely friendly to human health and the natural environment. It is an environmentally friendly rust-preventive oil, solving the pain point of traditional rust-preventive oil systems that cannot simultaneously achieve strong rust prevention and environmental friendliness.
