Technology of green plateless hot stamping ink
in packaging printing ink, anodized hot stamping, which is used to improve the decoration effect, once played an indelible role in the packaging industry because of its shiny effect of metal
organic color anodized aluminum and inorganic metal anodized aluminum were first used in hot stamping. Their specifications include 8 #, 12 #, 15 # and hot stamping temperature control of 75 ℃ ~ 90 ℃ and 60 ℃ ~ 70 ℃. Generally, flat and round pressing manual and automatic hot stamping machines are used. The hot stamping range is divided into ink paper, decojet film, glazing paper, polystyrene, PVC hard plastic, soft PVC plastic and wood talent
most electrochemical aluminum is made of polyester film as carrier (film base), resin layer coated with alcohol soluble dyes, vacuum sprayed metal aluminum, copper and organic color dyes, and then coated with adhesive layer. By stamping with metal engraving, metal corrosion or photosensitive resin plate hot press or air stamping with curved surface on books, plastics, leather and other materials (commonly known as hot copper, aluminum and color electrochemical aluminum), the added value of packaging, printing and decoration is greatly improved
however, at present, due to the shortage of electrochemical aluminum resources, high prices, waste pollution and the longer time of processing photographic plate making, it has long been unable to meet the requirements of the packaging and printing industry, let alone the needs of the advertising and building materials industries. Therefore, it is imperative to find a high-quality and low-cost version free hot stamping oil, Yang et al. To obtain the composite of multilayer poly (2-allyl-2-methylammonium chloride) - modified graphene and manganese oxide by self-assembly method, which has high capacitance and high cycle times. Ink substitution is imperative
based on the increasing interest of researchers in carbon fiber reinforced thermoplastic, we have carried out the analysis of the properties of anodized aluminum and the research work of plateless hot stamping ink products. After repeated tests, pilot production and comparative demonstration, the hot stamping ink we developed can approach the effect of electrochemical aluminum on printing materials, and the ink system has rich raw material resources and is more expensive than the traditional electrochemical aluminum duty room. In the hot stamping ink system, we boldly adopt Tianjin Li Biochemical Factory:
① introduce antioxidants to improve the resistance of hot stamping products
② introduce anti ultraviolet absorbent to enhance and extend the quality characteristics of hot stamping products
③ introduce stabilizer to improve the stability of hot stamping ink in storage and transportation
the application test shows that it can not only replace anodized in the following methods: hot stamping on traditional round flattening or flat printing machinery, but also more suitable for rotary round flattening large batch direct hot stamping and manual normal temperature or heating hot stamping technology. The development of this product has opened up a new hot stamping way for China's packaging industry, cultural and educational publicity, building materials, and advertising accessories
