AI Technical Summary

Technical Problem

When the polyimide film is directly used for thermal transfer printing, the transfer ink is easy to remain and difficult to remove.

Method used

A easy-to-clean coating is uniformly applied to the polyimide film, including distilled water, starch, polyvinyl alcohol, carboxymethyl cellulose, sodium carboxymethyl starch, urea, vapor phase silica and gelatin, ink transfers through thermal transfer technology, and coating is removed using a special cleaning agent.

Benefits of technology

The transfer ink on the polyimide film is easy to clean and not easy to remain, making the film reusable, reducing costs, low pollution, and wide application environment.

Abstract

The invention provides an easy-to-clean coating for a heat transfer printing polyimide film and a preparation method, and relates to the technical field of easy-to-clean coatings for polyimide films, the easy-to-clean coating comprises the following materials: distilled water, starch, polyvinyl alcohol, carboxymethyl cellulose, sodium carboxymethyl starch, urea, fumed silica and gelatin; heat transfer paper is directly replaced by the polyimide film easy-to-clean coating for transfer printing, transfer printing ink is prevented from remaining on the surface of the polyimide film, so that the polyimide film can be repeatedly coated and used, the transfer printing ink is easy to clean and not prone to remaining, cost is effectively reduced, pollution is low, and the application environment is wide. The easy-to-clean coating cleaning agent is prepared, and the cleaning efficiency of the easy-to-clean coating on the surface of the polyimide film is high, so that the easy-to-clean coating is coated on the surface of the polyimide film to replace transfer paper, the transfer printing effect is improved, the polyimide film can be recycled, and the base material loss is small.
