Abstract
The invention relates to the field of chemical industry paint, in particular to an environment-friendly aqueous paint remover. The paint remover is prepared by mixing and compounding the following components in parts by weight: 25-45 parts of dichloromethane, 7-8 parts of vinyl alcohol, 6-7 parts of propanol, 3-9 parts of methyl cellulose, 7-11 parts of diethyl carbonate, 3-4 parts of a surfactant, 20-24 parts of liquid paraffine, 5-6.5 parts of a thickening agent, 12-14 parts of phosphoric acid, 1-2 parts of sodiumnitrite and 12-14 parts of a solvent. The environment-friendly aqueous paint remover disclosed by the invention is high in depainting speed and is unlikely to volatilize; the aqueous paint remover can be directly applied to a painting surface under a normal atmospheric temperature for depainting, and the paraffine for volatilization resistance is contained in the components, so that the paint remover is favorable for renewedly painting workpieces of which the paint films are removed; the paint surfaces of automobiles, electric appliances, furniture and the like can be effectively removed, and the surfaces of metal and wood are not damaged. The paint remover is simple in manufacturing working procedures, is convenient to operate, is low in cost of raw materials, and has no residues, so that the paint remover is suitable for factory type large-scale production.
Description
technical field [0001] The invention relates to an environment-friendly water-based paint remover, which belongs to the technical field of paint removers. Background technique [0002] With the development of the economy, people are increasingly asking for the construction technology of removing old paint and repainting for anti-corrosion painting and renovation in the fields of transportation, industry, construction, and house decoration. The paint stripping technology products currently on the market, although the old paint can be removed, but the paint stripping effect is not good, and it is accompanied by irritating chemical smell, low toxicity, and will corrode low-quality materials, reduce the service life of the substrate, and seriously affect the refurbishment. Coating quality and other issues. Contents of the invention [0003] The invention provides an environment-friendly water-based paint remover, which solves the problems in the prior art. The paint remover...
