Abstract

The invention discloses a vapor phase rust inhibitor containing tung oil. The vapor phase rust inhibitor containing tung oil is prepared from the following raw materials, by weight, 0.5-1 part of tung oil, 1-2 parts of peanut oil, 0.5-1 part of patchouli oil, 1-2 parts of urotropine, 1-2 parts of glyceryl monooleate, 0.5-1 parts of ethyl cinnamate, 0.5-1 part of terpinyl acetate, 0.1-0.2 parts of bamboo leaf flavone, 6-8 parts of chitosan, 2-4 parts of hydroxypropyl-beta-cyclodextrin, 0.3-0.5 parts of polysorbate 80, 6-8 parts of sodium tripolyphosphate, 1-2 parts of sodium citrate, 8-10 parts of a modification aid and 40-50 parts of water. The rust inhibitor simultaneously has contact rust inhibition and vapor phase rust inhibition efficacies, has the advantages of fast film formation, uniform film, good toughness, good rust inhibition effect, long time, and slow release and controlled release effects, and is suitable for occasions having both requirements of waterborne rust inhibition and sealed space vapor phase rust inhibition.

Description

technical field [0001] The invention relates to the field of metal treatment, in particular to a gas-phase antirust agent containing tung oil and a preparation method thereof. Background technique [0002] Metal processing parts are prone to rust during production, processing and transportation. 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 vapor phase rust inhibitor is to automatically and continuously sublimate and volatilize into gas. When the gas reaches saturation, ...
