Process coating process for bronzing paper Tail pool hot stamping paper
The main information of
hot stamping hot stamping is electrochemical aluminum, also known as
hot stamping aluminum, which is composed of a polyester film substrate and a transfer layer.
Variety of hot stamping foil: can be divided into roll foil and single foil.
Hot stamping hot stamping is the application of special foil, which transfers the characters and patterns to the appearance of plastic products at a certain temperature. The advantage is that this method does not require the external table to stop disposal, and the color printing can be stopped by simple installation. In addition, It can print products with metallic luster such as gold and silver. The
Hot stamping paper has the following information: 1#, 8#, 12#, 15#, 18# universal signatures are commonly used. According to the color points, the commonly used ones are: Gold and silver foil, brown red foil, light blue foil, black, red, green, etc., 1# anodized aluminum: suitable for hot stamping on the background is light-colored ink, softer texture paper, leather, varnish, silk and plexiglass or plastic Appearance.
8#Electrified aluminum: suitable for hot stamping on paper, varnish, leather, 12# anodized aluminum: suitable for hot stamping plexiglass, hard plastic, and partial glazing paper appearance, 15# anodized aluminum: can be used in plastic film, soft plastic products Hot stamping, 18# anodized aluminum: Anodized aluminum is suitable for hot stamping. The background color is dark ink and thick line paper products. On leather, the quality and influence factors of hot stamping: hot stamping hot stamping is the application of hot pressing transfer. Principle, under certain temperature and pressure, the hot-melt silicone resin layer and the adhesive are thermally coagulated. After the silicone resin is condensed, the adhesion is reduced, and the aluminum layer is peeled off from the base film. The mixture adheres the aluminum layer to the hot stamping material, and the aluminum layer with the color material is the appearance of the hot stamping material.
Bronzing paper is essentially a carrier coating transfer process coating film. According to the international manufacturing regulations, it is divided into five conventional process flows. According to the application data or the difference of the complexity level of these five processes, it is also the difference in the price of today's hot stamping paper market. One of the important reasons for the element.
The manufacturing steps are as follows:
The first coating: the first coating is called the centrifugal layer, also called the peeling layer. When hot stamping, the coloring material, aluminum and rubber layer can be quickly separated from the PET polyester film and transferred and bonded. On the exterior of the object, the materials used for the peeling layer of bronzing paper are mainly silicone oil, paraffin wax and water wax. These three materials have the same effect in the stripping process, but their respective physical properties determine their application range. Silicone oil is a hot-melt coating with a melting point of about 98.7 °C. The spraying process is simple. The defects are uneven spraying and unstable. It is a secondary heating when using hot stamping. Generally, silicone oil is not used as a centrifugal layer for hot stamping paper. Paraffin wax has stable physical properties. It requires professional spraying equipment to spray paraffin wax on PET film in solid, powder and mist form as peeling coating for hot stamping paper. It is the best peeling of the most commonly used hot stamping paper in the world. According to the coating data, water wax is generally not used as a peeling coating material for hot stamping paper because of its low melting point.
The second coating: the second coating is called the maintenance layer. It mainly uses clear oil, ethyl ester, resin, etc. as the maintenance coating material. This layer is mainly used to maintain the effect of the pigment layer and the fine aluminum layer. Strengthen the brightness of bronzing paper after gilding, and some domestic enterprises that consume bronzing paper often save this layer or save this layer with the third layer of pigment layer, so this is also a lot of domestic hot stamping paper. It is not as good as the reason for the brightening effect of imported hot stamping paper.
The third coating: the third coating is called the image layer, also known as the pigment layer, which is mainly composed of synthetic resin and dye, which constitutes the color of the bronzing paper, such as red, blue, green, gold, etc. Like color or color, it is also a layer of resolution elements for a wide range of gilding paper colors.
The fourth coating: the fourth coating is called the fine aluminum coating. It is composed of aluminum metal evaporated by vacuum at high temperature, cooled and sublimated. The main function of the aluminum coating is to reflect the light and make the dyed layer appear metal. Gloss, there are two common aluminum plating processes, the first one is aluminum-plated vacuum evaporation week, and the second is aluminum-plated gun. Their respective characteristics are that the evaporation week equipment is more expensive, the manufacturing process is complicated, and the main application is aluminum vapor. Sublimation makes the aluminized layer evenly condensed on the PET coating film, the aluminum plating effect is good, the aluminum plating gun equipment is simple, and the manufacturing process is relatively simple. The main defects are uneven spraying, and easy to produce black spots of plating.
