Problems solved by technology

[0004] Paint stripping is a very important process in the surface treatment process of metal workpieces. The paint strippers currently on the market are generally formulated with aromatic hydrocarbons, ketones and other solvents or strong acids. Not only is the paint stripping efficiency low, but it is also flammable, toxic, and High volatility and strong corrosion not only cause environmental pollution, but also endanger the health of operators, and do not meet the increasingly stringent environmental protection requirements

Abstract

The invention provides a paint remover. The paint remover is prepared from, by weight, 35%-75% of main solvent, 5%-25% of co-solvent, 5%-15% of an activating agent, 8%-15% of a volatilization inhibitor, 1%-5% of a corrosion inhibitor and 0.1%-1.2% of a surfactant. The invention further provides a preparation method of the paint remover, that is to say, the materials are stirred and mixed to be uniform according to the weight proportion. The paint remover has the advantages of being high in paint removing efficiency, low in volatilization and smell, non-inflammable, little in harm to environment and the like, can be stably stored for a long term and is safe, mild and free of damage to workpieces. The preparation method is very simple, easy to control and operate and convenient to use.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of metal surface treatment, in particular to an efficient, safe and environment-friendly paint remover and a preparation method thereof. [0003] 【Background technique】 [0004] Paint stripping is a very important process in the surface treatment process of metal workpieces.
