Method for preparing anti-rust oil

Abstract

The invention discloses a method for preparing anti-rust oil. The method comprises the following raw materials in parts by weight: 85 parts of 46# antiwear hydraulic oil, 5 parts of neutral barium petroleum sulfonate, 6 parts of aluminum stearate, 5 parts of polyoxyethylene rosin ester, 5 parts of asphalt, 4 parts of hydrogenated castor oil, 5 parts of 1,2,3-benzotriazole, 3 parts of polyisobutene, 5 parts of a coalescing agent, 5 parts of dodecanamine, 5 parts of N-octadecylamine oleoylsarcosinate and 1.5 parts of sorbitan monooleate. The anti-rust oil cannot be easily discolored or oxidized, cannot influence the appearance of a workpiece, has excellent comprehensive performance, has high salt fog resistance, humidity resistance, ageing resistance and the like, and has good cleaning performance; the surface tension of an oil film can be improved by adding the coalescing agent, the oil film can be uniformly sprayed, spreading performance on the surface of the metal workpiece is good, the formed oil film is uniform and stable, and the protective effect for metals is improved.

Description

technical field [0001] The invention mainly relates to a preparation of oil, in particular to a preparation method of antirust oil. 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 requiremen...
