Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a recyclable paint remover, which has the advantages of high paint removal efficiency, strong dissolving power, high waste liquid recycling rate and low waste water treatment cost, and it has no pungent smell, It does not contain heavy metals and carcinogens, has no effect on human health and does not cause corrosion on the surface of the workpiece. It is safe and reliable to use, has no pollution to the environment, and is environmentally friendly. It solves the problem of using halogenated paint removers and natural gas. When water or white electric oil is used as paint remover, it not only contains harmful heavy metal substances or carcinogens, which has an impact on human health and pollution to the environment, but also corrodes metal workpieces, and the paint removal efficiency is low , poor paint removal effect, high cost of sewage treatment and low recycling rate of waste water

Abstract

The invention relates to a paint remover capable of being used circularly. The paint remover is prepared from D40 solvent oil, 2-ethoxyethanol, dipropylene glycol mono butyl ether, butyl acetate, alcohol solvent, ketone solvent and penetrant. The paint remover has the extremely high capacity of dissolving a paint film, the paint removing speed is high, the paint removing efficiency is high, the performance is stable, the comprehensive cost is low, recycle and reuse can be achieved, one one hand, various paint such as alcohol acid, nitryl, epoxy, polyester and polyurethane can be removed, and on the other hand, the paint remover is suitable for performing paint removing on powder coated workpiece, two-color oil coating on vacuum plating (PVD) or water plating workpiece and the like, the paint removing effect is good, the flash point is high, the safety factor is high, volatility is high, toxicity to a human body does not exist, waste paint remover generated by an enterprise in the use process can be recycled and reused through a vacuum distillation recovery machine, no sewage can be generated in the use process, sewage discharge is avoided, waterless cleaning can be achieved for theenterprise, the environmental protection pressure is reduced, and the cost is low.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a two-color paint suitable for various paints such as alkyd, nitro, epoxy, polyester and polyurethane, and suitable for powder spraying, electrophoresis paint, vacuum electroplating (PVD) and water-plating workpieces Recyclable paint strippers for stripping oiled coatings. Background technique [0002] In the fields of precision electronics, hardware electroplating, machining and other fields, it is traditional to use halogenated paint strippers and Tianna water or white electric oil to strip the workpiece. Halogenated paint strippers and Tianna water or white electric oil are both It is an irritant gas, which has an impact on human health and is a toxic substance. Among them, halogenated paint remover is a product that has been eliminated from international control, and the ingredients of Tianna water or Baidian oil contain a large amount of n-hexane and Aromatic hydrocarbons (...
