Abstract

The invention discloses a paint remover and a preparation method thereof. The raw materials of the paint remover comprise silicon dioxide, a zeolite powder, sodium nitrate, potassium sulfate, zinc stearate, polyethylene glycol, dichloromethane, ethyl acetate, carboxymethyl cellulose and water. The preparation method comprises the following steps: adding the sodium nitrate, potassium sulfate, zincstearate and polyethylene glycol into water, performing uniform mixing, adding the carboxymethyl cellulose, and performing heating and stirring to obtain a first mixed solution; then mixing the silicon dioxide, the zeolite powder, dichloromethane and ethyl acetate to form a second mixed solution; and adding the first mixed solution into the second mixed solution, and performing grinding in a colloid mill to obtain the paint remover. The paint remover is suitable for removing paints commonly used at present, and has the advantages of short removal time, good removal effect, and great reductionof the safety risk of a user.
