Problems solved by technology

Precious metals, especially pure gold or pure silver, have good ductility, but for those thinner and thinner sheet precious metal products, if there is only precious metal, it is easy to break and deform when bent or folded when the thickness is thin enough to a certain extent, and Gold and silver are easily oxidized and cannot be directly used in the production of pure gold (silver) red envelopes, envelopes and other products

Embodiment 1

[0046] Such as figure 1 As shown, a composite precious metal sheet is composed of a protective layer 100, a precious metal sheet layer 200, an adhesive layer 300 and a base layer 400 that are fully attached in sequence, wherein the thickness of the protective layer 100 is between 0.001-0.3mm Between, the thickness of the noble metal sheet layer 200 is between 0.002-0.5 mm, the thickness of the adhesive layer 300 is between 0.001-0.08 mm, and the thickness of the base layer 400 is between 0.001-3 mm. (The so-called comprehensive adhesion means that the shapes of each layer are the same, the side dimensions except the thickness are equal, and the layers are fully covered)

[0047] The material of the protective layer 100 is a transparent PET film or UV ink (polyethylene terephthalate is the most important variety in thermoplastic polyester, and the English name is Polyethylene terephthalate for short PET, commonly known as polyester resin. UV (Ultraviolet light curing) ink refe...

Embodiment 2

[0051] Such as figure 2As shown, a composite precious metal sheet is composed of the first protective layer 101, the first precious metal sheet layer 201, the first adhesive layer 301, the base layer 400, the second adhesive layer 302, the second noble metal sheet layer 202 and a second protective layer 102, wherein the thicknesses of the first protective layer 101 and the second protective layer 102 are both between 0.001-0.3mm, and the first precious metal sheet layer 201 and the second precious metal sheet The thickness of the layer 202 is between 0.002-0.5mm, the thickness of the first adhesive layer 301 and the second adhesive layer 302 are both between 0.001-0.08mm, and the thickness of the base layer 400 is between 0.001-3mm between. (The so-called comprehensive adhesion means that the shapes of each layer are the same, the side dimensions except the thickness are equal, and the layers are fully covered)

[0052] The material of the first protective layer 101 and the...

Embodiment 3

[0056] A red envelope, which is a pocket structure formed by cutting, folding and splicing the composite precious metal sheet in the first or second embodiment above.

[0057] Such as Figures 3 to 8 As shown, the red envelope is a pocket structure formed by folding and splicing a front piece 1, a back piece 2, a cover piece 3, and two wing pieces 4 cut from the composite precious metal sheet in the first or second embodiment above. The precious metal sheet is cut and folded to form a front piece 1 and a back piece 2 facing each other. The bottom joint of the front and back pieces 1 and 2 is a crease and the top is a pocket opening. The left and right sides of the front piece 1 are respectively a wing piece 4 , and the height of the two wing pieces 4 is equal to that of the front piece 1 . The fins 4 are in the form of strip-shaped rounded rectangles for easy bonding.

[0058] The two wings 4 are integrated with the front piece 1, and the two wings 4 are fixedly connected to...

Abstract

The invention discloses a composite precious metal sheet which is composed of a protective layer, a precious metal sheet layer, a bonding layer and a substrate layer which are sequentially and comprehensively attached. The composite precious metal sheet is of a multi-layer layered structure, the precious metal sheet layer has good ductility, the protective layer and the substrate layer on the two sides of the precious metal sheet layer enable the composite precious metal sheet not to be prone to fracture and deformation when the composite precious metal sheet is bent or folded, and the use range of the precious metal sheet is widened; and in addition, due to the protective layer, the composite precious metal sheet is not easy to oxidize even if being directly touched by hands or exposed in the air for a long time. The composite precious metal sheet is not easy to crack and deform when being bent or folded, and is not easy to oxidize when being directly touched by hands and exposed in the air for a long time, so that the composite precious metal sheet can be used for manufacturing red envelopes and envelopes. Red envelopes and envelopes made of the composite precious metal sheet are light, thin, attractive, not prone to breakage and deformation and suitable for repeated utilization and long-term storage.

Description

technical field [0001] The invention relates to the technical field of layered precious metal sheet and its application. Background technique [0002] Precious metals are usually mainly used to make jewelry, decorations, handicrafts, gifts or collectibles. Precious metals, especially pure gold or pure silver, have good ductility, but for those thinner and thinner sheet precious metal products, if there is only precious metal, it is easy to break and deform when bent or folded when the thickness is thin enough to a certain extent, and Gold and silver are easily oxidized and cannot be directly used in the production of pure gold (silver) red envelopes, envelopes and other products. Contents of the invention [0003] The purpose of the present invention is to provide a composite precious metal sheet, which has good ductility by designing it into a multi-layer layered structure, which is not easy to be broken and deformed when bent or folded, and is not easy to be touched by ...
