Abstract

The invention belongs to the field of a water-solubility peelable paint, and discloses water-solubility peelable paint and a preparation method and application thereof. The paint comprises the following components in parts by weight of 100 of polyvinyl alcohol, 15-30 of alkyl polyglycoside, 3-8 of a flexibilizer, 10-30 of modified polyalcohol or modified polyalcohol derivatives, 0.5-1.0 of a water-solubility antifoaming agent, 0.5-2.0 of a flatting agent, 1-3 of a thixotropic agent, 0.1-0.5 of a base material wetting agent, 0.5-1.0 of a peelable adjusting agent and 300-400 of water. The alkylpolyglycoside, the modified polyalcohol derivative plastifier and the like which are good in compatibility are added, so that normal-temperature water-solubility is realized. After the paint is filmed, the paint can resist heavy oil pollution, and after being peeled, the paint film can realize rapid water-solubility and can be cleaned; and the used and peeled paint film can be directly water-soluble, and enters sewers without waste paint film pollution.

Description

technical field [0001] The invention belongs to the field of water-based peelable paint, in particular to a water-soluble peelable paint and its preparation method and application. Background technique [0002] As a temporary protective coating with low adhesion and strong cohesion, the strippable coating has the advantages of convenient coating, easy film formation, anti-corrosion and corrosion resistance, pollution release and anti-friction. Its development began during World War II. With the development of polymer chemical technology and the increasing market demand, it emerged in Japan, the United States and some European countries in the 1970s and produced large-scale production. with application. It is mainly used in the temporary protection of aerospace devices, weaponry, large machinery, automobiles, high-quality optical lenses, etc., and the removal of radioactive isotope pollution on nuclear industry equipment. [0003] From the perspective of the mechanism of ac...
