Abstract

The invention provides a waterborne paint stripper and belongs to the technical field of paint. The waterborne paint stripper is prepared from the following raw materials in parts by weight: 30-50 parts of propylene carbonate, 5-15 parts of pyrrolidone, 3-8 parts of sodium hydroxide, 2.5-4 parts of potassium permanganate, 0.5-1.5 parts of metasilicate, 0.8-1 part of sodium dodecylbenzenesulfonateand 0.01-0.1 parts of sodium citrate. The paint stripper has high paint stripping efficiency, is corrosion-free to a substrate and low in volatility, can effectively strip various organic coatings, such as epoxy resin coatings, polyurethane resin coatings, organic silicone resin coatings, polyester coatings and the like. The paint stripper reduces use of harmful organic substances and is more environmentally friendly and safer.

Description

technical field [0001] The invention relates to a water-based paint remover, which belongs to the technical field of chemical solvents. Background technique [0002] The paint remover is a liquid composed of aromatic compounds and high-solvent solvents. It has a strong ability to dissolve paint films. The paint remover is fast and efficient. It can remove a wide range of coating types and is suitable for alcohol Acid, nitro, polyurea-formaldehyde rubber type vinyl, epoxy, polyester, polyurethane and other paints, exterior wall coatings, powder spraying, coating removal, strong paint removal ability. [0003] In daily life, under the influence of environment and physical machinery, with the prolongation of service time, the coating often fails locally or in a large area, such as loss of gloss, powdering, peeling, cracks, scratches, substrate corrosion, etc. Defects such as orange peel, cracks, and pulverization occur during the preparation of the coating, resulting in the ap...
