Problems solved by technology

[0003] However, iron painting works in the prior art have always been faced with the difficult problem of anti-corrosion treatment, therefore, it is necessary to provide a method for anti-corrosion treatment of iron painting surface
[0004] In view of the above problems, the invention patent with publication number CN 106427360 A in the prior art discloses a surface treatment method of iron painting and iron painting, the method includes cleaning-blueing treatment-rinsing-painting treatment steps, although to a certain extent The anti-corrosion performance of the iron painting is guaranteed, but the integrity of the paint layer on the surface of the iron painting can only be preserved for 2-3 years
[0005] Another example is that the invention patent with publication number CN 106319510A discloses a method for anticorrosion and decoration of iron painting surface and iron painting. method, although the treatment is simple, the effect on improving the anticorrosion performance of iron painting is not obvious

Abstract

The invention discloses an anti-corrosion treatment method for the surface of iron paintings, which relates to the technical field of post-treatment of iron paintings. It is first cleaned by acid and alkali solution, then derusted, and then passivated to form a protective film on the surface of iron paintings after cleaning, slowing down Corrosion, and a layer of anti-corrosion paint is coated on the surface of the iron painting, and then a layer of anti-corrosion paint is coated on the surface of the anti-corrosion paint after drying, which greatly improves the anti-corrosion performance of the iron painting, and can make the anti-corrosion ability of the iron painting works more than 20 years.

Description

technical field [0001] The invention relates to the technical field of post-treatment of iron paintings, in particular to a method for anti-corrosion treatment of the surface of iron paintings. Background technique [0002] Iron painting, formerly known as "Iron Flower", is one of the unique arts and crafts in China and a unique arts and crafts in Wuhu City. Iron painting has absorbed the composition method of traditional Chinese painting and the techniques of gold and silver jewelry, paper-cutting, sculpture and so on. It uses low-carbon steel as raw material, uses iron instead of ink, and uses hammer instead of pen. Frame, frame and other processes, as well as the techniques of "knocking" and "drilling", are exquisitely formed into various works of art such as landscapes, figures, flowers, insects, fish, birds, and animals. It integrates folk paper-cutting, carving, mosaic and other artistic expression techniques into one, adopts the Chinese painting method, contrasts bla...
