Problems solved by technology

[0005] At present, most domestic paint remover products contain harmful ingredients, which have a negative impact on the environment and are more harmful to the human body. The paint removal effect is not good, and the paint film peels off slowly. As a result, the life of the ship is affected, the specific needs of the ship's paint removal maintenance cannot be met, and the safety of the operator is also affected.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to an environment-friendly paint remover for ships and a preparation method thereof. Background technique [0002] Coating is the most common method in anti-corrosion, especially for ships, which have been in a corrosive environment for a long time and are more widely used. But once the paint film is damaged, the corrosion rate will be faster, and it needs to be maintained in time and repainted. In order to ensure the quality of the new paint film, the old paint film must be removed before painting. [0003] The film-forming material of the paint film is composed of many movable segments of polymer macromolecules, which can be dissolved or swelled in appropriate organic solvents. The paint stripping principle of the paint remover is to destroy the spatial structure of the paint film or the bonding force between the paint film and the substrate. When the organic solvent mole...
