Problems solved by technology

However, the effective mist particles sprayed by the existing gas-phase antirust agents are relatively large, and the technical surface of the parts cannot be completely covered after use, and it cannot reach the fine seams of parts or assemblies with complex structures and small pores. , so that the use effect is not good; due to the large diameter of the mist particles, riding on the metal wall of the inner wall of some rust-proof closed and narrow spaces, the mist particles cannot be effectively suspended, even if the suspension time is short, so the corrosion inhibition effect is not good. Affect the service life of components, so most of the current aerosol rust inhibitors cannot fully meet the needs of manufacturers

Abstract

The invention provides a gas-phase rust preventive oil. The gas-phase rust preventive oil comprises the following ingredients in parts by weight: 50-80 parts of #32 engine oil, 5-10 parts of octadecyl amine, 3-5 parts of petroleum sodium sulfonate, 1-4 parts of petroleum barium sulfonate, 2-5 parts of sodium benzoate, 3-6 parts of polyvinyl alcohol, 1-3 parts of zinc butyloctyl dithiophosphate, 2-6 parts of polyether, 1-5 parts of sorbitan monooleate, 2-4 parts of tripropylamine octanoate, 1-6 parts of dodecyl alcohol and 2-5 parts of amino-modified silicone oil. The rust preventive oil provided by the invention contains a gas-phase rust preventive. In the process of rust prevention, the part free from oil is protected under the action of the gas-phase rust preventive; the rust preventive oil does not contain toxic ingredients, such as sodium nitrite, thereby being safe and environmentally friendly in use.

Description

technical field [0001] The invention belongs to the technical field of metal antirust, and in particular relates to a gas phase antirust oil and a preparation method thereof. Background technique [0002] Corrosion is one of the main forms of damage to metal products. In order to avoid corrosion and reduce losses, people have adopted various methods, and using antirust agents to protect metal products is one of the most common protection methods at present. Anti-rust agent is composed of adding one or more anti-rust additives and auxiliary additives to the basic components of petroleum. It is easy to use, low in cost, good in effect and simple in operation. It is widely used in the metal products industry at present. However, the effective mist particles sprayed by the existing gas-phase antirust agents are relatively large, and the technical surface of the parts cannot be completely covered after use, and it cannot reach the fine seams of parts or assemblies with complex st...
