A kind of fast-drying strippable coating and preparation method thereof

Abstract

The invention discloses quick-drying peelable paint. The paint is prepared from, by weight, 60-70 parts of first alcohol soluble resin, 60-70 parts of second alcohol soluble resin, 0.05-0.1 part of a flatting agent, 1-10 parts of a wetting agent, 0.2-1 part of defoamer, 3-8 parts of composite iron-titanium powder and 10-20 parts of functional fillers. The invention further provides a preparation method of the paint, part of the wetting agent, the defoamer, the composite iron-titanium powder and ethyl alcohol are added into a high-speed dispersion machine, after dispersion is conducted, the functional fillers are added, dispersion is conducted, then, the first alcohol soluble resin, the second alcohol soluble resin and the remaining defoamer, wetting agent and flatting agent are added, the mixture is stirred to be uniform, dispersion is conducted continuously, after mixing is conducted to be uniform, filter residues are removed through filtration, and then the quick-drying peelable paint is obtained. The paint has the advantages of being high in drying speed, good in anti-rust property and good in peelability.

Description

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

Problems solved by technology

Among them, solvent-based strippable coatings containing aromatic hydrocarbons have good performance, but they gradually fade out of the market because they do not meet environmental protection requirements. Although the current water-based strippable coatings meet environmental protection, they have long drying time (2~3 hours), When used on the surface of metal objects, the metal surface is prone to rust and other problems. It is difficult to meet the needs of high-performance coatings for rapid production on high-speed production lines and social development, which greatly limits its popularization and application.
