Problems solved by technology

[0003] However, with the enhancement of people's awareness of environmental protection and the need for anti-rust development, the requirements for gas-phase anti-rust agents are also getting higher and higher. At present, most of the anti-rust agents on the market have low anti-rust efficiency, short anti-rust time, and single anti-rust objects. Therefore, it is of great significance to develop an environmentally friendly, efficient, durable, and applicable to a variety of metal vapor phase rust inhibitors

Abstract

The invention relates to the technical field of preparation of a gas phase antirust agent, in particular to an efficient durable gas phase antirust agent and a preparation method thereof. The efficient durable gas phase antirust agent comprises a component A and a component B according to a mass ratio of 8-11: 1. The component A comprises the following raw materials in percentage by weight: 50-70%of sodium benzoate, 15-25% of benzotriazole, 5-15% of ammonium molybdate, 2-7% of cyclohexylamine carbonate and 2-8% of urotropine. The component B is celery extract. The antirust agent does not contain nitrous acid antirust components, is green and environment-friendly, has a synergistic antirust effect between component A and component B, has high antirust efficiency and long antirust time dueto short film forming time and short sublimation time, and has excellent antirust performance on multi-metals such as steel, copper and the like.

Description

technical field [0001] The invention relates to the technical field of gas-phase antirust preparation, in particular to a high-efficiency and durable gas-phase antirust agent and a preparation method thereof. Background technique [0002] Metal parts are prone to rust during production, processing, transportation, and use. Once rust occurs, it will not only affect the appearance and function, but may even cause waste of resources. Anti-rust agent is a chemical agent added to the medium to achieve the purpose of metal anti-rust. It can form a protective film on the surface of the component and inhibit the corrosion caused by moisture and other chemical components. However, some metal workpieces have curved holes and other parts that are difficult to reach with oil rust prevention, and the vapor phase rust inhibitor has a special protective effect on this. The principle of gas-phase rust inhibitor is to automatically and continuously sublimate and volatilize into gas. When th...
