Aircraft anticorrosion oil cleaning agent

Abstract

The invention belongs to the chemical cleaning field and in particular relates to a colorless and transparent anticorrosion oil cleaning agent high in deoiling effect for use in the civil aviation aircraft maintenance process. Based on the total quantity of the cleaning agent product, the cleaning agent comprises the following components by weight: 40-50% of major solvent, 30-40% of isoparaffin solvent oil, 10-25% of dearomatization solvent oil, 1-5% of cosolvent and 0-2% of penetrant. The cleaning agent product produced according to such a formulation is capable of thoroughly removing the anticorrosion oil, oil contamination, dust and the like on the surface of the body and the structural members of an aircraft without damaging the aircraft materials, and has no residue after cleaning and no harm on the human body.

Description

1. Technical field [0001] The invention relates to the field of chemical industry, in particular to an anti-corrosion oil cleaning agent used in the maintenance process of civil aviation aircraft. 2. Background technology [0002] Corrosion is a major problem encountered in the maintenance process of civil aviation aircraft. Corrosion has caused huge economic losses to civil aviation aircraft, and will endanger the safety of aircraft in serious cases. Anti-corrosion oil is widely used in the maintenance of aircraft as an effective means to control the generation and expansion of corrosion. [0003] Aircraft anti-corrosion oil is an oily substance that is coated on key parts of the aircraft to prevent corrosion of aircraft surfaces or structural parts. After the aircraft is assembled and painted, some key structural parts, such as the connecting part of the aircraft landing gear and the airframe, are often folded up and down, which will cause the paint film to break.

Problems solved by technology

Major domestic and international aircraft manufacturers and scientific research institutions have done a lot of research work on the formula of aircraft parts cleaning agent products, but the results are not ideal

The main disadvantages: slow cleaning speed, slow volatilization speed, incomplete cleaning, etc.

For example the document CN101403123A of prior art discloses a kind of aircraft cleaning agent, and it comprises perchlorethylene, nitrogen methyl pyrrolidone, No. 200 solvent naphtha, ethylene glycol butyl ether, but its cleaning ability in practical application is still insufficient, Cannot meet the increasingly stringent requirements of aerospace applications

CN1137559A discloses a cle
