Environment-friendly gas-phase rustproof oil and preparation method thereof

Abstract

The invention relates to an environment-friendly gas-phase rustproof oil and a preparation method thereof, and belongs to the technical field of metal surface treatment. The rustproof oil is prepared from the following raw materials in parts by weight: 100 to 120 parts of mineral oil, 8 to 15 parts of benzotriazole, 6 to 10 parts of salicylic acid cyclohexylamine, 1 to 3 parts of sorbitan mo-nooleate, 1 to 3 parts of aluminium stearate, 0.5 to 6 parts of antioxidant, 0.5 to 1 part of mildew preventive and 0.5 to 1 part of polydimethyl siloxane. The rustproof oil has the contact-type rustproof performance and also has the gas-phase rustproof performance. The rustproof oil is capable of automatically sending gas at a normal temperature to form a protective film on a metal surface, thereby inhibiting the metal from being corroded and rusted. Thus, the effective rustproof function can also be performed for positions which cannot contact with the rustproof oil. In addition, a rustproof agent without barium is adopted and toxic components such as sodium nitrite and the like are not contained in the rustproof oil, so that the rustproof oil is safe and environment-friendly when being used.

Description

technical field [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to an environment-friendly gas phase antirust oil and a preparation method thereof. Background technique [0002] The problem of metal corrosion pervades all walks of life in the national economy. It will greatly damage the performance and commercial value of metal products, and even cause major failures and make equipment scrapped. The so-called rust is a mixture of oxides and hydroxides formed on the metal surface due to the action of oxygen and water. Iron rust is red, copper rust is green, and the rust of aluminum and zinc is called white rust. It is difficult for machinery not to come into contact with oxygen, moisture or other corrosive media in the air during operation and storage. These substances will undergo electrochemical corrosion and rust on the metal surface. To prevent corrosion, the above substances must be prevented from contacting the m...

Problems solved by technology

However, most anti-rust oils can only play the role of contact anti-rust, and for those parts that cannot be contacted with anti-rust oil, they cannot be effectively protected against rust.

In addition, most of the anti-rust oils on the market are barium-containing anti-rust oils. Barium is a heavy metal that has a great impact on the environment, soil, and human health.
