Abstract

The invention relates to a powerful paint stripper comprising the following components by weight percent: 0-5 percent of surface active agent, 72-78 percent of dichloromethane, 0-3 percent of ethylacetate, 0.78-0.8 percent of thickener, 0.6-0.7 percent of ceresin wax, 4.85-10 percent of phenol, 5-9 percent of alcohol, 0-6 percent of methanoic acid, 0-6 percent of ammonia water and 0-1 percent of sodium nitrite. The invention can effectively remove paint on the metal surface of planes and on the train wheel surface so as to perform flaw detection and repaint on the metal materials without damaging metal and wood surfaces, and has excellent depainting performance, low use amount and low depainting cost.

Description

technical field [0001] The invention is a paint remover which can effectively remove the paint on the metal surface of aircraft and the paint on the surface of train wheels. Background technique [0002] At present, there are more than 3,000 domestic civil aviation airliners and military aircraft, and the number of aircraft is increasing at a rate of more than 50 per year. Generally, it needs to be repaired once every 3-4 years, and the average consumption of each flight is 60 liters. About 3 million yuan, and the total amount of 3 million yuan is only used for aircraft paint removal throughout the year. Including the aircraft of other general aviation companies, the national consumption is more than 4 million yuan. At present, the domestic train maintenance industry consumes more, with an annual consumption of more than 30 million yuan. Other civilian industries (machinery maintenance industry) use the largest amount, with an annual consumption of more than 50 million yuan...

Problems solved by technology

At present, the domestic train maintenance industry consumes more, with an annual consumption of more than 30 million yuan. Other civilian industries (machinery maintenance industry) use the largest amount, with an annual consumption of more than 50 million yuan. Although some domestic manufacturers also produce it, the effect is None of them meet the requirements. For example, the Datuopu Military Airport Aircraft Maintenance Factory in Hunan uses dichloromethane mixed with paraffin to deal with it. Although it has a certain effect, it is not clean. It is labor-intensive to remove the old paint film manually. Very large, the cost of paint removal has increased a lot
