Abstract

The invention relates to a UV cured strippable water-based coating. The UV cured strippable water-based coating is prepared from, by weight, 60-70 parts of UV cured water-based polyurethane resin, 0.05-0.1 part of flatting agent, 1-10 parts of wetting agents, 1-3 parts of thickening agents, 0.2-1 part of antifoaming agent, 2-5 parts of film coalescing agents, 3-6 parts of photoinitiator, 3-8 parts of rust-proof resist, 0.10-0.30 part of mould-proof antibacterial agent, 10-20 parts of functional filler and 10-20 parts of water-based stripping agents. The invention further provides a preparing method of the coating. The preparing method includes the steps that a part of the wetting agents, the antifoaming agent, the rust-proof resist and deionized water are added into a high-speed dispersion machine and dispersed through stirring, the functional filler is added and dispersed through stirring, and the UV cured water-based polyurethane resin, the remaining antifoaming agent, the remaining wetting agents, the flatting agent, the film coalescing agents, the water-based stripping agents, the photoinitiator and the mould-proof antibacterial agents are added and uniformly stirred, continue to be dispersed and are filtered after being mixed to obtain the UV cured strippable water-based coating.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and in particular relates to a UV-curable peelable water-based paint and a preparation method thereof. Background technique [0002] Peelable paint is a temporary protective material with polymer as the main film-forming substance. It is sprayed on the surface of the object when it is used, and it will protect the object for a short time after the film is formed; The film layer is gently peeled off from the surface of the object to be coated by hand, which will not only cause no damage to the surface of the object to be coated, but also make the appearance of the original device as clean as new. Strippable coatings are widely welcomed by industries such as instruments, meters, home appliances, machinery, automobiles, and electronic appliances due to their convenient coating and easy peeling, and are developing rapidly. [0003] At present, there are mainly two types of solvent-based strip...
