Abstract

The invention discloses a nontoxic environment-friendly paint remover which is prepared from compound solvent, cosolvent, corrosion inhibition accelerator, thickening agent, penetrant and stabilizer. The invention has the following advantages: 1. the paint removing speed is high: the paint remover can dissolve common coatings within 20 minutes; 2. the paint remover does not corrode ferrous metals and non-ferrous metals; 3. the paint remover has high flash point, and is nontoxic and free of methylene chlorides, and the raw materials are biodegradable; 4. the paint remover can be used at -15-50 DEG C, and is free from the environmental effects of high humidity and high heat; 5. different from other paint removers, the metal surface subjected to the paint remover disclosed by the invention can prevent rust for 1 week; and 6. the paint remover is free of volatile inhibitor paraffin, thickening agent polymethyl methacrylate and other substances contained in the traditional paint remover, and the residues after paint removal can be easily flushed and cleaned with water. The invention can be used for overhaul and paint removal of ships, tanks, nuclear facilities, airplanes, automobiles, seamount drogues and other facilities, and can also be used for overhaul and paint removal of oil storage tanks, bridges, wharves, electrical enclosures and the like.

Description

technical field [0001] The invention belongs to the field of paint removers and relates to a non-toxic and environment-friendly paint remover. Background technique [0002] With the continuous construction of informationized troops, the military equipment of our army is becoming more and more sophisticated, the application of high-tech equipment is more extensive, the application of new materials is more common, and new weapons and equipment are constantly being put into service. For example, during the training process of aircraft, ships, tanks and automobiles, due to my country's vast territory, the temperature, humidity and heat in the north and south regions are quite different. Aging, cracking, peeling and peeling of the equipment coating will cause the paint film to lose its protective and decorative effect. The equipment must be maintained and maintained after training or exercises to maintain the integrity of the equipment. If it is to be repainted during the mainten...
