Noble metal and base material compound embossing process method and process product thereof

Abstract

The invention provides a noble metal and base material compound embossing process method. The method comprises the steps of 1, a material cutting procedure, wherein sheets are obtained and cut; 2, preparation of a base material, wherein blister varnish is bonded to a to-be-processed surface of the base material, and the base material and the noble metal sheets are cut according to a certain size ratio and shape; 3, heating and plastic sealing, wherein the cut noble metal sheets are compounded with the cut base material; 4, oil pressing, wherein a compounded product is placed on a mold formingsurface for oil pressing to achieve a preset surface effect on the surface of the product. The corresponding noble metal and base material compound embossing process product is also disclosed and comprises a noble metal layer, the base material and a blister varnish layer, wherein the base material is disposed on one side of noble metal and used for supporting the noble metal layer, and the blister varnish layer is disposed between the noble metal layer and the blister varnish layer and used for connecting the noble metal layer with the blister varnish layer and is a mixture of butadiene styrene, a polystyrene butadiene copolymer, rosin pentaerythritol ester, ethyl acetate and synthetic wax.

Precious metals are more used in the manufacture of collectibles, jewelry, etc. With the rapid development of social economy and culture, people's demand for handicrafts is also increasing. Handicrafts made of certain substrates and precious metals have a unique texture and are favored by people. , can be applied in daily life, such as: stamps, postal cards, postal envelopes, postal folders, passbooks, commemorative banknotes, test banknotes, craft gift books, paintings and other covers, and the thickness of precious metals can be made thinner and thinner, which not only reduces the It is heavy to reduce the purchase cost, and it can be made more beautiful. The current process is usually to bond the precious metal and the base layer directly with ordinary glue for compounding, and most of them are bonded by hand. The glue itself has Adhesion, when the metal sheet is in contact with the substrate in the early stage, the adhesion effect will occur, and it cannot be guaranteed that the alignment will be accurate at the first contact, so the production efficiency is not high enough, so the product quality cannot be guaranteed. The material is easy to fall off, and the process is complicated, which cannot be mass-produced well, and the relative process cost is high, and the yield is low. In addition, manual lamination cannot completely make the metal sheet and the paper base tightly bonded, and there will be residues in the middle. Void, there is gas in the void, after the subsequent oil pressure, the air may be trapped inside, making the surface of the product appear to have a bubble effect, which is not desired

The final product obtained by gluing has been tested in practice and the base material and the precious metal layer can be separated by manual disassembly. During the separation process, the gold sheet will be wrinkled or partially broken, but the adhesion of the gluing is not very strong. Therefore, there will be no large-scale tearing, which also proves from one side that the bonding method is not an ideal way to connect the base material and the precious metal sheet, and the composite performance is not enough. It is necessary to find a better material or method to replace it.

In addition, when ordinary glue is used in the process of handicraft processing, it is very difficult to obtain high-purity precious metals in the process of recycling defective products (usually by using chemicals to dissolve the glue), and usually involves a large number of chemical reactions. Derivatives or glue components, resulting in a large waste of precious metals and increasing the overall cost of the product
