Engine part special-purpose rust-preventative oil

Abstract

The invention belongs to the technical field of engine rust prevention and discloses engine part special-purpose rust-preventative oil. The engine part special-purpose rust-preventative oil comprises, by weight, 0.5-1 part of dodecenyl succinic acid, 3-10 parts of barium dinonyl benzene sulfonate, 1-5 parts of dibutyl phthalate, 0.1-1 part of benzotriazole, 2-5 parts of petroleum barium sulfate, 2-6 parts of polyisobutylene and the balance of an aviation lubricant. A preparation method of the engine part special-purpose rust-preventative oil comprises heating the aviation lubricant to 100-120 DEG C, carrying out dehydration, carrying out cooling to the room temperature, then slowly adding the other components into the aviation lubricant, and carrying out stirring until the components are completely dissolved and the materials are uniformly mixed. The engine part special-purpose rust-preventative oil can be used for long-term storage of various metal parts of the engine and prevention of rust on various metal plating layers. An assembly treated by the engine part special-purpose rust-preventative oil has a rust-proof period of 3-5 years.

Description

technical field [0001] The invention belongs to the technical field of engine rust prevention, in particular to a special antirust oil for engine parts. Background technique [0002] The anti-rust work of the engine and parts directly affects the product quality, performance and service life of the engine. The application of anti-rust technology prevents the engine from Metal Parts are corroded during production and transportation, which ensures the assembly quality and service life of the car. According to the structure, the engine can be divided into two types: anti-rust of parts and anti-rust of the whole machine. According to the sequence of production process, it can be mainly divided into three parts: anti-rust between processes, anti-rust during transportation and anti-rust during storage. The external rust prevention of the engine can be solved by phosphating, painting, oiling, etc.; the internal exposed metal surfaces, depressions, and the interior of the pipeline...
