Background
Rust is considered a "final destroyer" and costs up to $ 4000 billion or more per year for rust, far exceeding the sum of other natural disasters. Since the pipelines and the internal structure of the large-scale equipment are complex and the large-scale equipment cannot be completely soaked or completely sprayed with the anti-rust oil, the large-scale equipment is difficult to be completely rusted through soaking or spraying the anti-rust oil. The gas-phase rust preventive oil can achieve good rust preventive effect through dual properties of contact and non-contact with the gas-phase rust preventive oil, so that large-scale equipment is generally subjected to rust preventive treatment through the gas-phase rust preventive oil.
Most of the gas-phase rust preventive oil on the market contains gas-phase rust preventive agents with strong pungent odor, such as dicyclohexylamine, cyclohexylamine, tributylamine and the like, and the gas-phase rust preventive agents cause the deterioration of human body quality after being taken for a long time, even cause diseases and cause great harm to human bodies. And the gas phase rust preventive oil on the market has the phenomenon of poor film formation uniformity and poor gas phase performance, so that the rust preventive performance is poor or worse. Therefore, a gas-phase rust preventive oil which has no pungent smell, uniform film formation and excellent gas-phase rust preventive performance needs to be researched.
