Enameled wire paint remover as well as preparation method and use method thereof

Abstract

The invention relates to an enameled wire paint remover as well as a preparation method and a use method thereof. The enameled wire paint remover is characterized by being prepared from the following components in parts by weight: 20-30 parts of dichloromethane, 13-16 parts of diethylene glycol monomethyl ether, 10-15 parts of ethanol, 8-12 parts of glycol, 0.3-0.8 part of dimethyl sulfoxide, 4-6 parts of sodium dodecyl benzene sulfonate, 0.02-0.1 part of 98 percent by weight of concentrated sulfuric acid and the balance of water. The preparation method comprises the following steps: uniformly mixing the dichloromethane, the diethylene glycol monomethyl ether and the dimethyl sulfoxide to obtain liquid A; uniformly mixing the ethanol, the glycol, sulfuric acid, the sodium dodecyl benzene sulfonate as a surface active agent and the water to obtain liquid B; uniformly mixing the liquid A and the liquid B to obtain a finished product. Compared with an existing organic paint remover, the enameled wire paint remover contains no benzene, acetone and other poisonous substances, is low in cost, green and environment-friendly, and quick and efficient in paint removal, does not corrode a copper substrate, is prepared and used at a normal temperature, is mild in use condition and has the advantage of being simple and convenient to operate, time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of paint removers, and in particular relates to an enameled wire paint remover with mild use conditions and environmental protection, a preparation method and a use method thereof, which are used for removing paint from the surface of waste enameled wires. Background technique [0002] Enameled wire is a commonly used electrical material. Because of its good insulation effect and waterproof ability, it is widely used in electrical equipment such as motors, generators, water pumps, electric welding machines, and transformers. While enameled wires are widely used, a large number of scrapped enameled wires in the production process and old enameled wires in aging electrical equipment are inevitably generated. Therefore, the recycling and reuse of waste enameled wire is very important to my country's circular economy. [0003] At present, the methods of recovering metal copper in enameled wire include fire met...

Problems solved by technology

Although this paint remover is easy to operate and removes paint cleanly, its components contain nitric acid, which is highly volatile and corrosive. It is easy to cause corrosion of the copper substrate during use, and at the same time produces high hazards to the human body and the environment. nitrogen dioxide gas, which limits its practical application
