Polyester anti-rust oil and preparation method thereof

Abstract

The invention discloses polyester anti-rust oil, which consists of the following raw materials in parts by weight: 40-45 parts of N32# mechanical oil, 25-35 parts of 200SN base oil, 4-5 parts of oleic acid polyoxyethylene ester, 2-4 parts of dibutyl phthalate, 2-3 parts of dibutyl adipate, 2-3 parts of 2-aminoethyl heptade-alkenyl imidazoline, 3-4 parts of ozocerite, 1-2 parts of phenylethanolamine, 3-5 parts of coalescing agent, 1-2 parts of carbonate bicyclic amine and 2-3 parts of chromic acid tert-butyl ester. The anti-rust oil prepared by the invention is difficult to discolor and oxidize, cannot influence the appearance of a workpiece and has high comprehensive performance, high salt mist resistance, high damp-heat resistance, high aging resistance and high cleanability; by the coalescing agent, the surface tension of an oil film is improved, so that the oil film can be uniformly sprayed; the spreading performance on the surface of a metal workpiece is high; the formed oil film is uniform and stable; and the metal retaining protection effect is enhanced.

Description

technical field [0001] The invention mainly relates to an oil, in particular to a polyester 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-rust...

[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
