Problems solved by technology

Organic paint strippers are generally formulated from solvents such as alcohols, aromatics, ketones, and chlorinated hydrocarbons. They are basically insoluble in water, have high volatility, are flammable, explosive, and highly toxic, and are easy to operate in the environment. Pollution, high cost
Most of the inorganic paint removers are caustic soda, which can only be removed under heating conditions. The process is complicated, the operation is cumbersome, the energy consumption is high, the paint removal efficiency is low, and the scope of application is small. Be eliminated

Abstract

The invention provides an alkaline paint remover coated on paint film surface so as to remove the paint film. The alkaline paint remover is a non-toxic and environmentally-friendly milky viscous liquid, with water as a main solvent, and can be directly coated on the paint film surfaces to remove paint. The invention further relates to a preparation method and an application of the alkaline paint remover.

Description

Technical field: [0001] The invention provides an alkaline paint remover coated on the surface of a paint film for removing the paint film, which is a milky white viscous liquid that is non-toxic and harmless to the environment, and its main solvent is water, which can be directly brushed on The surface of the paint film is peeled off. At the same time, the present invention also relates to the preparation method and application of the paint stripper. On the one hand, water is used as the main solvent to change the traditional solvent-based method. On the other hand, the present invention has no volatilization and does not pollute the environment. Background technique: [0002] At present, the commonly used paint removers are divided into two categories: organic and inorganic. Organic paint strippers are generally formulated from solvents such as alcohols, aromatics, ketones, and chlorinated hydrocarbons. They are basically insoluble in water, have high volatility, are flam...
