Water-based aircraft paint remover and preparation method thereof

Abstract

The invention discloses a water-based aircraft paint remover and a preparation method thereof, and belongs to the technical field of fine chemical engineering. The paint remover comprises a main solvent, a cosolvent, a penetrating agent, a wetting stripping agent and the like. The wetting stripping agent adopted by the paint remover can form a molecular-level protective layer on the surface of a metal substrate, plays a role in stripping a paint film and inhibiting corrosion, and can protect the surface of the metal substrate while improving the paint removal efficiency. The paint remover has the advantages of small volatilization loss, environmental protection, no pollution, no need of secondary cleaning with gasoline and other organic solvents, no harm to human bodies, and no pollution to the environment. The paint remover has excellent paint removal performance and does not corrode a metal substrate at the bottom of the paint film; and no organic matter is left on the surface of the paint removed metal substrate.

Description

technical field [0001] The invention relates to a water-based aircraft paint stripper and a preparation method thereof, belonging to the technical field of fine chemicals. Background technique [0002] In the production process of aircraft parts, such as aircraft engines, coating is one of the important protection methods for metal products and their processing. In the process of forming, fine blanking, etc., in order to prevent abrasive wear, adhesive wear, bite and friction, etc. Usually, a targeted coating is selected to protect the substrate, improve the physical resistance of the substrate, and resist scratches, abrasions, bumps, and other physical defenses caused by general transportation and processing. At the same time, it can also improve the chemical resistance of metal substrates, resistance to strong acids, strong alkalis, corrosion, water, oil, sun exposure, etc. [0003] Although the coating has a long-term protective function, after its processing is complet...

Problems solved by technology

Solvent paint strippers are generally composed of methylene chloride and phenol as the main components and other volatile organic solvents. Most solvent paint strippers contain a large amount of toxic and volatile substances, which have the potential to pollute the environment and harm the environment. The health of the operator is seriously endangered and other issues
