Basic introduction Chinese name: cloth bronzing paper source: domestic and imported China consumption place: Yangtze River Delta and Pearl River Delta raw materials: cloth bronzing paper (anodized) introduction, principle, structure, characteristics, application, selection, operation method, related problems, other related, introduction cloth bronzing paper sources are mainly domestic and imported. Imported gilding paper requires higher performance, and the price is naturally high. In recent years, with the popularity of domestic cloth bronzing, the quality of domestic bronzing paper is also constantly improving. In addition, the characteristics of low cost and easy operation of cloth bronzing paper also add a lot of added value to cloth. Cloth bronzing has brought great business opportunities to gold foil manufacturers in China. China's Yangtze River Delta and Pearl River Delta are huge consumers of gold foil. For example, Hao Fei provides these customers with professional, high-quality and suitable bronzing materials, and the service is convenient and thoughtful. Its cloth gilding paper has many colors and types, and there is a lot of choice. Cloth bronzing paper needs bronzing paste as a medium. The principle of hot stamping paper technology is to transfer the aluminum layer in anodized aluminum to the surface of the substrate by using the principle of hot pressing transfer, forming a special metal effect. Because the main material used in bronzing is anodized aluminum foil, bronzing is also called anodized hot stamping. Electrochemical aluminum foil is usually composed of multilayer materials, and the substrate is often P E, followed by separation coating, color coating, metal coating (aluminum plating) and glue coating. In the printing industry, electrochemical aluminum foil is commonly used for hot stamping on paper, which is called bronzing. Bronzing is a general term for a process. Hot stamping doesn't mean hot stamping is gold? There are many materials for gilding paper, including gold, silver, laser gold, laser silver, black, red, green and so on. The structure of structural hot stamping paper is divided into: base layer, peeling layer, color layer, electroplating layer and adhesive layer. The first layer: the base layer is generally made of biaxially stretched polyester film with the thickness of 12 micron -25 micron, which is mainly used to support the coating attached to it and facilitate continuous hot stamping during processing. It has tensile and instantaneous high temperature resistance. The second layer: the peeling layer is generally coated with silicone. The main function is to make the pigment, aluminum and adhesive layer after hot stamping leave the polyester film quickly, transfer and adhere to the surface of the hot stamping object. The release layer should have good peeling performance, otherwise it will blur the graphics and text of hot stamping and expose flowers, which will affect the quality of hot stamping products. The third layer: the main components of the color layer are film-forming, heat-resistant, transparent and suitable synthetic resins and dyes. Commonly used resins include polyurethane nitrocellulose, melamine formaldehyde resin and modified rosin ester. In production, resin and dye are dissolved in organic solvent to make color paste, then coated and dried. There are two main functions: one is to display color; The second is to protect the aluminized pattern printed on the surface of the article from oxidation. The colors of electrochemical aluminum foil are gold, orange, gray, red, blue and green. The color of the color layer is endowed with luster after aluminizing, and the color has certain changes, such as yellow turning into gold after electroplating and drilling, and gray turning into silver after aluminizing. The coating requirements of color layer are fine, without any small particles, avoiding trachoma and coating evenly. The fourth layer: electroplating layer: the film coated with pigment is placed in the vacuum chamber of a vacuum continuous aluminizing machine. Under a certain vacuum degree, the aluminum wire is melted and continuously evaporated to the color layer of the film through resistance heating to form an aluminized layer. The main function of aluminized layer is to reflect light, change the color of colored layer and make it appear metallic luster. The fifth layer: the adhesive layer is generally a fusible thermoplastic resin. According to the different hot stamping materials, you can choose different resins. Resin can be dissolved in an organic solvent or prepared into an aqueous solution, coated on the aluminum layer by a coating machine, and dried to form a glue layer. Its main function is to bond hot stamping materials to hot stamping objects. When hot stamping, one of the main reasons for the bad phenomenon of hot stamping is that the adhesive layer does not match. According to different objects, the models of electrochemical aluminum foil used for hot stamping are also different. Characteristics of hot stamping paper: the optimum temperature for hot stamping is 95- 135 degrees. Please select different types of hot stamping paper for trial printing according to different hot stamping substrates and patterns. Hot stamping covers a wider area, which can be divided into three types: one is hot stamping small strokes (small area for special use); The second is 6*6 mm field hot stamping (universal); The third is 10* 10 mm field hot stamping (large area dedicated). Hot stamping paper specifications: width 0.64m * length 120m/ roll; Can also be customized according to customer requirements, such as: 240 meters/roll, 360 meters/roll and so on. Precautions for hot stamping paper storage: storage at room temperature, moisture-proof, pressure-resistant and sun-proof. Suitable for all kinds of fabrics, fabrics, etc. Such as T-shirts, swimwear, fashion, sportswear, clothing, sweaters, shirts, underwear, bags, casual shoes, jeans and so on. Bronzing paper bronzing range 1, clothing cloth bronzing paper (high-end fashion, cloth, T-shirts, bags, casual shoes) 2, soft plastic bronzing paper (plastic accessories, electronic products, ballpoint pens, clock faces, etc. ) such as ASB, PVC, PMMA (acrylic gilding) 3, OPP laminating, paper gilding paper (high-grade cigarette packs and wine boxes) and PE gilding paper (cosmetic boxes, hoses and high-grade daily necessities) 5. Electrical wire drawing paper, double-sided bronzing paper (DVD, VCD, combination speaker, transparent panel, high-end electrical appliances, video panel, etc. 6. Glass and metal gilding paper (cosmetic bottles, wine bottles, wine glasses, metal nameplates, tea cups, etc.). ) 7.PU leather and imitation leather bronzing paper (fashion shoes) bronzing machines (pneumatic bronzing machine, automatic continuous bronzing machine, bronzing machine) must pay attention to matching the bronzing substrate when choosing bronzing paper/anodized. What kind of substrate to choose? The types and models of gilding paper are different, which is determined by the structure of gilding paper itself. The fifth layer of gilding paper is a glue layer, which is generally a fusible thermoplastic resin. According to the different materials used in hot stamping, choose different resins. Operation method: use 33T( 120 mesh) screen to print the bronzing paste on the cloth, and dry it after each printing, generally at least three times. If you need an outstanding feel, you can print more times or make the screen thicker. 150℃ baking for 5- 10 minutes, and gilding after the pulp is completely dried. Temperature 140- 160℃, time 15-25 seconds, pressure above 4kg/ cm (ironing); Temperature 180℃, time 1 s, pressure 4kg/cm2 (scald). The above are the parameters of 16μm thick gilding paper, and the parameters of 12μm thick gilding paper can be reduced appropriately. The parameters are not fixed and can be adjusted according to the actual situation. Related problems When the bronzing machine is heated to room temperature, the bronzing paper still cannot be ironed or peeled off cleanly for two reasons: 1, and the bronzing paper is not suitable for hot stamping substrate; 2, hot stamping temperature is not enough, you can heat up the test again. If the blue light is emitted after hot stamping, it means that the hot stamping temperature is too high, and it can be cooled properly before ironing. Be careful not to wipe the bronzing surface or cloth by hand after bronzing. It is recommended to do water washing test after 24 hours, and the effect is the best. Other relevant storage conditions: 1, temperature 5℃-20℃ 2, vertical storage 3, humidity 30-70% 4. Avoid direct sunlight. Domestic gilding paper is generally: 12μm (thickness) ×64cm (width) × 120m (length). 12 μ m×1.5m×1000/2000/3000m (1.5m wide, large roll) The imported gilded paper is generally:16 μ m× 64cm×/kloc-0.
