Stable general-purpose type laser stamping foil of electrified aluminuim and its technique

Abstract

A stable and universal process for preparing the laser thermoprinted electrochemical aluminium foil includes mixing parting material, assistant and cosolvent to obtaining the parting material, preparing color material from isocyanate, cellulose resin, diallyl titanate resin, pigment, assistant, mixed solvent and resin, preparing cementing material from acrylic resin, cellulose resin, ethylene-vinyl acetate resin, filler, pigment, assistant, and mixed solvent, sequentially coating them on PET carrier film, laser die pressing and vacuum aluminizing.

Description

Technical field [0001] The invention relates to a laser anodized aluminum hot stamping foil and its technology. Background technique [0002] At present, with the development of modern science and technology, and the improvement of packaging and decoration grades. Laser anodized aluminum hot stamping foil is a higher-grade packaging and decoration material developed on the basis of ordinary anodized aluminum hot stamping foil combined with the development of laser technology, chemical raw material industry, and chemical formula technology. Since it came out, it has been welcomed by all walks of life, and it has been paid more attention in the packaging industry. Its consumption has increased significantly year by year, and it has the potential to replace ordinary anodized aluminum hot stamping foils. However, the environmental requirements are harsh in the production process. When the weather changes, especially when the relative humidity is greater than 80%, the production...

Problems solved by technology

However, the environmental requirements are harsh in the production process. When the weather changes, especially when the relative humidity is greater than 80%, the production process will be unstable, and a small space must be established in the key parts of the production workshop. It creates a special environment with a relative humidity of less than 70% for normal producti...
