Abstract

The invention discloses a biodegradable environmentally-friendly paint remover. The biodegradable environmentally-friendly paint remover is prepared from the following raw materials: a main solvent, a macromolecule solvent, acetic acid, a surface active agent, a thickening agent, a corrosion inhibitor and water. The invention also discloses a preparation method of the biodegradable environmentally-friendly paint remover. The paint remover prepared by the method has the advantages of fast paint removal speed, wide application range, no corrosion and low corrosion to a substrate, no influence on repainting, high boiling point, good stability, operation at a room temperature, simplicity, convenience, practicability and low production cost. The biodegradable environmentally-friendly paint remover is biodegradable and is an environmentally-friendly paint remover.

Description

technical field [0001] The invention relates to an emulsion paint remover, in particular to a biodegradable and environment-friendly emulsion paint remover. Background technique [0002] The paint remover is a liquid mixed with chlorinated hydrocarbons, ketones, esters, alcohols, benzene series and other solvents. It depends on a series of physical and chemical comprehensive effects such as dissolution, penetration, swelling, peeling and reaction, so as to destroy the spatial structure of the paint film or the bonding force between the paint film and the substrate, and realize the penetration of solvent molecules into the paint film polymer. In the molecular segment, the paint film dissolves; or the volume of the polymer macromolecule increases to generate internal stress. When the internal stress is enough to destroy the adhesion between the paint film and the substrate, the paint film is removed. [0003] Commonly used paint removers can be divided into alkaline paint rem...
