Embodiment Construction

[0017] An anti-corrosion synthetic aviation lubricating oil, composed of 90-95% polyol ester, 2%-5% arylamine ester, 1%-4% phenyl phosphate, 0.01%-0.5% benzotriazole derivative, imidazoline derivative 0.01% to 0.5% of acrylate copolymer and 0.0005% to 0.0100% by weight of acrylate copolymer.

[0018] The polyol ester is a product of pentaerythritol ester reacted with saturated fatty acid as the ester base oil.

[0019] The arylamine ester is an amine antioxidant prepared by oxidative coupling reaction of aniline and naphthylamine compounds.

[0020] The phenyl phosphate is an extreme pressure antiwear agent.

[0021] The benzotriazole derivatives are chelated complexes formed by the benzotriazole derivatives as antirust agents.

[0022] The imidazoline derivatives are corrosion inhibitors synthesized by using C10-C18 saturated or unsaturated fatty acids and amine compounds as raw materials.

[0023] The acrylate copolymer is an antifoaming agent synthesized by dropwise addi...

Abstract

The invention provides anticorrosive synthetic aviation lubricating oil and a production method thereof. The anticorrosive synthetic aviation lubricating oil is composed of the following components inpercentage by weight: 90%-95% of polyol ester, 2%-5% of arylamine ester, 1%-4% of phenyl phosphate, 0.01%-0.5% of a benzotriazole derivative, 0.01%-0.5% of an imidazoline derivative and 0.0005%-0.0100% of an acrylate copolymer. The polyol ester is conveyed into a blending kettle from a base oil tank, and meanwhile, nitrogen is conveyed into the blending kettle from a nitrogen tank; a stirring system is switched on, the polyol ester is heated to 55-80 DEG C by a heating system under stirring; the arylamine ester, the phenyl phosphate, the benzotriazole derivative, the imidazoline derivative and the acrylate copolymer are conveyed into a blending kettle from an additive tank, and the materials are fully mixed and stirred for 20 minutes to 2 hours, and then an obtained product is subjected to still standing, and the product is cooled to room temperature; the product is filtered, so that the filtered product is conveyed to a finished product tank, and a finished product is obtained by using a filling machine. The lubricating oil can be used as aviation lubricating oil.

Description

technical field [0001] The invention relates to the field of lubricating oil, in particular to an anti-corrosion synthetic aviation lubricating oil and a production method thereof. Background technique [0002] Carrier-based aircraft fly in the ocean environment and are often parked on the aircraft carrier. The aero-engine will be exposed to the high-salt marine atmospheric environment and seawater moisture splashing for a long time. During the parking period, it is in a high-salt, high-humidity, acidic atmosphere. These conditions will accelerate the aging of the main lubricating oil of the carrier-based aircraft and may lead to its gradual failure, and cause the engine bearing to be damaged or even scrapped due to corrosion. Therefore, aviation lubricating oil must have good anti-rust and anti-corrosion properties. At present, most of the lubricating oils used in China are standard lubricating oils, and there is no suitable anti-corrosion lubricating oil for selection. Th...
