The invention relates to the field of paint removers, and discloses a paint remover and a preparation method thereof, and a paint removing method. The paint remover is prepared from the following components in parts by
mass: 20 to 80 parts of
ether, 10 to 60 parts of
alcohol, 1 to 40 parts of inorganic alkali, 0.1 to 10 parts of a volatile inhibitor, 0.1 to 10 parts of a
corrosion inhibitor, 0.1 to 5 parts of a surfactant and 0.1 to 4 parts of a
thickening agent. The preparation method of the paint remover comprises the following steps: mixing the inorganic alkali, the
ether, the
alcohol, thevolatile inhibitor, the
corrosion inhibitor, the surfactant and the
thickening agent, and uniformly stirring to obtain the paint remover. According to the invention, the paint remover is low in
toxicity,
environmentally friendly, high in paint removing speed and good in paint removing effect, can avoid
corrosion on
metal base materials, improve the
rust resistance of iron materials, improve the painting
adhesive force of iron materials and effectively remove
phenolic aldehyde paint films,
alkyd paint films, nitro paint films,
polyurethane paint films,
epoxy resin paint films, water-based paintfilms and electrostatic
powder paint films.
