Embodiment 1

[0051] Raw material composition and mass percent are:

[0052] Barium Sulfate Petroleum 2%

[0053] Barium Dinonylnaphthalene Sulfonate 5%

[0054] Dodecenylsuccinic acid 0.85%

[0055] Benzotriazole 0.3%

[0056] Dibutyl phthalate 3.3%

[0057] Polyisobutylene 5%

[0058] Aviation lubricating oil balance;

[0059] Pour the aviation lubricating oil into the oil tank with heating equipment, heat it to 110-120°C for full dehydration, and then lower it to room temperature; then slowly add the rest of the raw materials into the oil tank, and stir continuously to dissolve them completely. After the materials are evenly mixed, the anti-rust oil of the present invention is obtained.

[0060] Apply the prepared anti-rust oil to parts made of aluminum alloy, iron, carbon steel, copper alloy, magnesium alloy, silver alloy, and parts with phosphating surface, blue surface, and silver-plated surface. The test results are shown in Table 1.

Abstract

The invention aims to provide thin-layer rust-preventative oil for an engine part and a method for preparing the same. The rust-preventative oil is prepared from the following components in percentage by weight: 2 to 3 percent of petroleum barium sulfate, 4 to 7 percent of barium dinonyl napthalene sulphonate, 0.5 to 0.9 percent of dodecene butane diacid, 0.1 to 0.5 percent of benzotriazole, 1.0 to 5.0 percent of dibutyl phthalate, 3 to 5 percent of polyisobutene and the balance of aviation lubricating oil, wherein the ratio of the two components comprising benzotriazole to dibutyl phthalate is 1:10 to 11.

Description

technical field [0001] The invention belongs to the field of antirust oil, in particular to a thin-layer antirust oil for engine parts and a preparation method thereof. Background technique [0002] The types of materials used in aero-engines are complex. With the improvement of engine performance, the types of metal materials used are increasing, and the shapes of materials are becoming more and more complex, and the requirements for the surface properties of materials are getting higher and higher. In addition to steel and aluminum, the types of aero-engine metals also include alloys such as copper, silver, and magnesium, and the addition of elements in various alloys is also more complicated. There are often multiple surface protection layers on the surface of various alloys, and the surface quality requirements are high. In addition, the structure of aero-engine parts is complex, and most of the parts used are assemblies composed of several metals. During the long-term s...
