Abstract

The invention relates to a special coating, in particular to a high temperature resistant strippable anti-corrosion coating and a preparation method thereof. The coating consists of a film forming agent, an auxiliary agent and a solvent, and the compositions in percentage by weight are as follows: 12 to 17 percent of the film forming agent, 5 to 10 percent of the auxiliary agent, and 73 to 83 percent of the solvent. The concrete preparation method comprises the following steps: the film forming agent, the auxiliary agent and the solvent are mixed according to the weight ratio, and then are stirred at normal temperature in a closed container to dissolve for 30 minutes to obtain a product. The coating takes a high molecular polymer as a film forming material, has the advantages of good acid, base and salt resistances, excellent toughness, remarkable high temperature resistance, easiness for coating, convenient unsealing, and no pollution to the surface of metal after a solidified coating film is stripped; in addition, the stripped coating film can be repeatedly used after the treatment.

Description

technical field [0001] The invention relates to a special paint, in particular to a high-temperature-resistant peelable anti-corrosion paint and a preparation method thereof. Background technique [0002] Corrosion of metal materials is most common in atmospheric environments, especially in some high-temperature environments. The usual protective measure is to apply paint. In order to remove the paint film during use, organic solvents are often used to dissolve the paint film, treated with alkaline water, or treated with physical methods such as bamboo knives and scrapers. However, these methods are difficult to remove the paint film. And damage the surface, labor-intensive and time-consuming. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of traditional coatings and provide a high temperature-resistant strippable anti-corrosion coating. [0004] The technical scheme of the present invention is: the high temperatur...
