Problems solved by technology

However, most of the current chemical paint removers are toxic and polluting to the environment. These chemical products contain dichloromethane, formic acid and other harmful substances. Generally speaking, the amount of dichloromethane used in the paint remover formulation Larger, the general volume ratio is as high as 60%, otherwise the paint removal efficiency will be significantly reduced, so this type of paint remover is more volatile and toxic; or some paint removers currently use strong acid or alkaline materials such as concentrated sulfuric acid , the paint removal effect is good, but the waste liquid will seriously damage the ecological environment

Abstract

The invention provides a water-based paint remover and a preparation method thereof, and relates to the technical field of fine chemicals, and the water-based paint remover comprises the following components: benzyl alcohol, ethylene glycol monobutyl ether, N-methyl pyrrolidone, gamma-butyrolactone, dimethyl sulfoxide, phenol, a surfactant, polyoxyethylene octyl phenol ether-10, ethanolamine, a corrosion inhibitor and water. The water-based paint remover has a good paint removal effect, does not contain strong acid components, avoids the problem of concentrated acid pollution in waste liquid, and does not contain dichloromethane and methanol which are harmful to human bodies and the environment. According to the preparation method of the water-based paint remover, the process is simple and efficient, the production process is low in toxicity and free of pollution, and waste caused by too high volatilization speed of the raw material solvent is avoided.

Description

technical field [0001] The present invention relates to the technical field of fine chemicals, in particular to a water-based paint stripper and a preparation method thereof. Background technique [0002] On the coating line, the paint coating formed on the hanger, especially the powder, electrophoretic coating and the surface coating of the parts that need to be reworked and repainted, need to be removed, otherwise it will affect the conductive effect of electrostatic coating and the recoating of the workpiece surface. quality after. However, most of the current chemical paint strippers are toxic and polluting to the environment. These chemical products contain methylene chloride, formic acid and some other harmful substances. Generally speaking, methylene chloride is used in the formulation of paint strippers. Generally, the volume ratio is as high as 60% or more, otherwise the paint stripping efficiency will be significantly reduced, so this kind of paint stripper is mor...
