Depainting cleaning method and depainting cleaning agent thereof



The invention discloses a depainting cleaning method and a depainting cleaning agent thereof. The depainting cleaning agent comprises the following components in percentage by weight: 0.1% to 0.5% of fatty alcohol ethylene oxide condensate, 0.3% to 2% of isomerism alkyl alcohol ether, 0.3% to 2% of alkyl methyl ammonium chloride, 0.2% to 1% of alkyl polyglucoside, and 0.2% to 1% of fatty alcohol-polyoxyethylene ether. According to the depainting cleaning method and the depainting cleaning agent thereof, crushed powdered plastic is dipped in prepared cleaning solution for 1 to 5 hours, then is agitated or scrubbed, and finally is rinsed for two to four times. The cleaning method disclosed by the invention is simple to operate and has a good depainting effect; and the depainting cleaning agent are matched with various raw materials to achieve complementary advantages, therefore, the plastic cleaning agent can show high abilities on permeating and cleaning, shows high separating performance on various TPO (polyolefin thermoplastic elastomer) coatings, and is odorless and colorless, is harmless to humans, can be recycled, and has relatively long service life.
