Abstract

The invention provides an easily-peelable high-efficiency UV ink. The ink can effectively protect metals, and has the characteristics of corrosion resistance, weather resistance, scratch resistance, abrasion resistance, high adhesion, strong acid and alkali resistance, high folding strength and the like; in addition, the UV protection ink can be effectively removed by using a paint stripper, is easy to remove, filter and separate, and does not cause any damage to metal.

Description

technical field [0001] The invention relates to an easy-to-peel high-efficiency UV ink and a preparation method thereof, belonging to the technical field of environmentally friendly inks. Background technique [0002] Metals, especially stainless steel, magnesium alloys, titanium alloys, and aluminum alloys, have been widely used in military industry, heavy industry, light industry, electrical industry, aerospace, ships, etc., or in daily necessities industry and architectural decoration industries. Metals tend to rust, fade, age and other problems under natural conditions, resulting in losses. For example, the widely used stainless steels are mainly divided into ferritic stainless steels, austenitic stainless steels, martensitic stainless steels, duplex stainless steels, and precipitated stainless steels. Hardened stainless steels and replacement austenitic stainless steels. Duplex stainless steel is divided into (duplex) ferritic / martensitic stainless steel, (duplex) mart...
