Dehydration anti-rust oil and preparation method thereof

Abstract

The invention discloses dehydration anti-rust oil. The dehydration anti-rust oil is prepared from the following raw materials in parts by weight: 38-42 parts of lamp coal oil, 38-42 parts of 150SN base oil, 4-5 parts of sorbitan fatty acid ester, 3-4 parts of polyethylene glycol, 2-3 parts of octylated diphenylamine, 1-3 parts of 2-aminoethyl heptadecenyl imidazoline, 2-3 parts of oil acid, 1-2 parts of isotridecyl alcohol polyoxyethylene ether, 2-3 parts of film-forming auxiliaries, 4-6 parts of magnesium sulfate, 1-2 parts of dibutyltin dilaurate and 1-2 parts of antioxidant 168. The anti-rust oil produced by using the preparation method hardly changes color and is hardly oxidized, has high comprehensive performance and high salt fog resistance, humidity resistance and aging resistance, and the appearance of workpieces is not influenced; the cleaning performance is high; and through the added film-forming auxiliaries, the surface tension of the oil film is improved, so that the oil can be uniformly sprayed and coated; and the spreading performance of the surface of a metal workpiece is high, and the formed oil film is uniform and stable, so that a protection function on the metal is improved.

Description

technical field [0001] The invention mainly relates to an oil, in particular to a dehydrated antirust oil and a preparation method thereof. Background technique [0002] With the rapid development of industries such as national defense and automobile manufacturing, the demand for metal sheets is increasing, and the requirements for the surface quality of the sheets are also getting higher and higher, because how to prevent corrosion and reduce the loss of production, transportation, and storage costs It is the top priority. At present, the common way to prevent metal corrosion is to coat the surface of the workpiece with a layer of anti-rust oil. At present, most of the traditional anti-rust oils are simple in composition and perform well in one or several specific aspects, but The overall performance is poor, some anti-rust oils have a short anti-rust period, some have poor salt spray resistance, and some paint films are unstable, which is difficult to meet the anti-rus...

[0002] With the rapid development of industries such as national defense and automobile manufacturing, the demand for metal plates is increasing, and the requirements for the surface quality of plates are also getting higher and higher, because how to prevent corrosion and reduce the loss of production, transportation and storage costs It is the top priority. At present, the common way to prevent metal corrosion is to coat the surface of the workpiece with a layer of anti-rust oil. At present, most of the traditional anti-rust oils have simple ingredients and have good performance in one or several specific aspects, but Poor overall performance, some anti-rust oils have a short anti-rust period, some have poor salt spray resistance, and some have unstable paint films, which are difficult to meet the anti-rust requirements
