Abstract

The invention provides a metal foil stamping method using ultraviolet-curable binder which can make metal foil and glass container bond closely no matter how much the thermal softening resin content in ultraviolet-curable binder is. The metal foil stamping method is suitable for glass container. The method includes four working procedures: Silicifying flame treatment procedure: using silicon alkyl compound whose boiling point is in the range of 10 to100 DEG as combustion gas, and spraying the glass container surface with the flame generated by the gas combustion; daubing the ultraviolet-curable binder procedure: the ultraviolet-curable binder contains 1-15 parts by weight of thermoplastic resin, 50-95 parts by weight of ultraviolet curing component, and 0.1-10 parts by weight of photo-initiating agent; curing procedure: irradiating the binder daubed on the glass container surface with ultraviolet to cure the binder. Stamping procedure: activating the cured binder and stamping the metal foil onto the glass container surface.

Description

technical field

[0001] The present invention relates to a metal foil hot stamping method using an ultraviolet curable adhesive. The glass container adopts a special surface treatment, and a special UV-curable adhesive is applied for metal foil hot stamping, so that the metal foil is tightly combined with the surface of the glass container. Background technique

[0002] For a long time, the metal foil hot stamping method has been widely used in the deep processing of glass containers. After smearing a thermosetting adhesive on the surface of the glass container, it is heated to make it semi-cured, and then the metal foil is pasted on the surface of the adhesive, and then heated and pressurized to make the metal foil adhere to the surface of the glass container.

[0003] This method of foil stamping using a thermosetting adhesive. It has been disclosed in JP-A-53-33723, JP-4-142517, JP-6-88449, and JP-7-67796.

[0004] However, the smearing method of the thermosetting adhes...
