Manufacturing method of heavy ion micropore antifault membrane

Abstract

The invention belongs to the anti false technical area including following procedures. The precoat film is made by pre coating the anticorrosive hot-melt adhesive on the anticorrosion plastic film. The plastic film exposed by the heavy ion becomes the irradiation film. The composite film is prepared by heating the precoat film and the irradiation film together. Then, the chemical etching makes the aperture of the heavy ion micropore in 3-5 mu m. After etching, with the precoat film being removed from the irradiation film covered, through the rinsing and baking processes, the anti-false film of the heavy oil is obtained. It is milk-white in the pattern area of the anti-false film and it keeps the original transparency in non-pattern area. The invention possesses the features of double-faced protection, the clear pattern, low cost and easy of preparing the precoat film in large scale.

Description

technical field

[0001] The invention belongs to the field of anti-counterfeiting technology, and in particular relates to a method for manufacturing a heavy ion microporous anti-counterfeiting film using the comprehensive technology of nuclear technology, chemical technology and printing technology. Background technique

[0002] In recent years, heavy ion microporous anti-counterfeiting technology has played an important role in the anti-counterfeiting of commodities with its superior anti-counterfeiting performance, and has emerged in the anti-counterfeiting industry. However, due to the complexity and immaturity of the technological process, the reduction of cost and the improvement of appearance and output are restricted.

[0003] The invention patents with application number 93106945.9 and application number 94104555.2 are manufactured by placing a template with a hollowed out pattern between the irradiation source and the organic film, and then irradiating the organic f...
