Problems solved by technology

Due to increasingly stringent environmental protection requirements, the raw material price of alkaline paint remover is low, but the corrosiveness of strong alkali and strong acid not only damages the substrate, but also has adverse effects on the human body and the operating environment
Ordinary solvent-based paint removers are less corrosive to the substrate, but the hazards of solvents to the human

Abstract

The invention relates to a novel paint remover and a preparation method thereof. The novel paint remover is composed of organic base, an organic solvent, and a corrosion inhibitor. During storage and application periods, the novel paint remover is coated by an oil sealant coating. The organic base is hydramine. The boiling point of the organic solvent is at least 200 DEG C. The corrosion inhibitor is a saccharide. The oil sealant coating is vegetable oil or mineral oil with a density lower than the novel paint remover. The oil sealant coating is insoluble or slightly soluble in the novel paint remover. The paint remover is simple to prepare, easy to use, and satisfies the requirement of environment protection. With the novel paint remover provided by the invention, various paint films can be removed, the paint removing speed is high, and no corrosion is brought to various substrates. Therefore, the paint remover is suitable to be used in paint removing of large complicated work-pieces and sensitive substrates.

Description

technical field [0001] The invention relates to the technical field of paint removers, in particular to a novel paint remover for removing the surface coating of workpieces with large complex structures and sensitive metal substrates and a preparation method thereof. Background technique [0002] At present, the new paint removers that are more commonly used are generally as follows: ①Alkaline paint remover: a new aqueous paint remover composed of alkaline compounds such as sodium hydroxide, sodium carbonate, etc.; ②Acidic paint remover: Aqueous solution composed of strong acid such as concentrated sulfuric acid, nitric acid, etc.; ③ Ordinary solvent-based paint remover: a paint remover composed of ordinary organic solvents such as ketones, esters, alcohols, and benzene and added with paraffin; ④ Chlorinated Hydrocarbon solvent-based paint remover: a new solvent-based paint remover based on methylene chloride, chlorobenzene, etc., and other auxiliary materials are added. Thi...
