Problems solved by technology

Numerous studies have found that replacing dichloromethane with alcohol, ether, ketone, ester and other solvents can reduce environmental pollution, but the paint removal efficiency is very different, especially for epoxy or polyurethane paint films. Under certain circumstances, the stripping time of the paint can be extended from a few minutes to several hours or even days, which undoubtedly proclaims the extension of the aircraft grounding time

Abstract

The invention provides a water soluble paint remover. The water soluble paint remover is characterized in that 1kg of the water soluble paint remover is prepared from the following raw materials: 300-400ml dichloromethane, 200-300ml phenol, 300-400ml weakly alkaline deionized water solution, 15-20g of industrial paraffin, 20-25ml surfactant and 1-20g of a thickening agent. The water soluble paint remover has the technical effects that coating can be directly carried out again after appropriate solvent cleaning and drying are carried out, a binding force of a paint film is not influenced, a repairing process is simplified, and the repairing cost is reduced.

Description

technical field [0001] The invention relates to the field of paint removers, in particular to a water-soluble paint remover. Background technique [0002] Aircraft are subject to long-term tests in different climates and environments around the world, and coatings are suitable protective materials for aircraft. After flying for a long time, the paint film on the surface of the aircraft is damaged, which requires regular maintenance and renovation. The paint removal of the whole machine is a big project, and after the paint removal, it is expected that the oxide film or coating of the base material will not be damaged, and it can be repainted directly after proper cleaning and drying. The bonding force of the paint film will not be affected, and the renovation efficiency will be improved. The paint stripping of aircraft is usually completed under the action of paint strippers. The paint strippers currently used are mainly formulated with organic solvents. It is based on the ...
