Abstract

The invention discloses a waterborne peelable protective paint which is composed of the components of, by weight: 60-100 parts of polyurethane emulsion, 30-40 parts of organosiloxane, 15-30 parts of modified polyacrylate, 10-20 parts of silicone, 20-40 parts of hydroxyethyl cellulose, 10-15 parts of rosin, 2-8 parts of a peeling accelerant, and balance of a water solvent. The waterborne peelable protective paint provided by the invention is green, environment-friendly, and low in cost. When a film is formed by using the paint, the film is aging-resisting, and is easy to peel. The film has good weatherability.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based peelable protective coating. Background technique [0002] Peelable coatings are usually used for temporary protection of cultural relics, precision parts, mechanical equipment and other items, and can also be used for dirt peelable layers of household appliances such as range hoods and exhaust umbrellas. Strippable protective coatings must meet the requirements for use in all weather conditions, that is, they must have excellent weather resistance. It must meet basic technical requirements: water resistance, light aging resistance, high temperature resistance, low temperature resistance, and maintain peelability when the climate changes repeatedly. [0003] Existing strippable coatings are solvent-based systems, which use a large amount of organic solvents. On the one hand, the high content of volatile organic compounds causes serious pollution to the production and use ...
