Description

Multipurpose alumite back adhesive and preparation method thereof
Technical Field
The invention relates to an alumite back adhesive, in particular to a multipurpose alumite back adhesive and a preparation method thereof.
Background
The hot stamping technology refers to that a special metal hot stamping plate transfers an electrochemical aluminum foil to the surface of a printing material in a heating and pressurizing mode. The technology carries out three-dimensional hot stamping, so that the patterns and texts processed by hot stamping have obvious layers, form a relief effect on the surface of a printed matter, generate a strong visual angle impact effect, and be widely used in the high-grade printing fields of tobacco, wine and the like. The hot stamping process has many advantages, and is popular with users and consumers. However, the performance of the electrochemical aluminum foil restricts the development of the process, so that the performance of the electrochemical aluminum foil is inevitably improved. However, one of the main factors affecting the performance and quality of the electrochemical aluminum foil is the electrochemical aluminum backing adhesive. The alumite is a new material which takes a polyester film as a base film and is coated with various coating paints with different chemical properties, and the specific coating is as follows: the first layer is carrier film, and the second layer is from the type layer, and the third layer is the colour layer, and the fourth layer is the layer of aluminizing of evaporating, and the fifth layer is the adhesive layer: so that the gilding paper and the product form adhesive force combination at high temperature. At present, the demand for the electrochemical aluminum is huge at home and abroad; for foreign countries, the development trend of the adhesive of the electrochemical aluminum foil is relatively specific, but the price is higher; the development of the adhesive of the electrochemical aluminum foil in China is biased to be general and the cost is lower. However, the stability, the curing property and the heat resistance of raw materials such as a release agent, a coloring agent, a binding agent and the like used in the prior electrochemical aluminum products in China are not ideal enough, so the development of the electrochemical aluminum coating industry is greatly restricted. Particularly, the adhesive layer and the domestic adhesive layer have the defects of hot stamping and gold flying, plate pasting, poor hot stamping property, non-ideal hot stamping adhesive force, low glossiness and the like, and the product performance is inferior to that of imported products, so the market is basically occupied by foreign products. However, the price of the adhesive layer of the imported product is high, for example, chinese patent CN101343522A discloses a holographic positioning alumite high-speed hot stamping gum and a preparation method thereof, which are used for preparing an alumite adhesive layer suitable for high-speed hot stamping of various base materials by blending various resins, however, the quality stability of the co-blended gum preparation process is poor, and the price is high.
In order to solve the problems of poor bonding effect and high price of the adhesive of the existing electric aluminum hot stamping base material, Chinese patent CN103694933 discloses an acrylate modified adhesive, a benzene-free hot melt adhesive and an application method. However, the silicon powder is added in the formula of the benzene-free hot melt adhesive, the aim is to improve the cutting performance of the product, and meanwhile, the silicon powder and the silicon dioxide powder have the following defects: 1) if the gum layer contains silicon powder, the surface tension of the gum layer and the cohesiveness of the adhesive are influenced, and the hot stamping and the printing performance are further influenced; 2) the benzene-free hot melt adhesive cannot be commonly used for two different production processes of an oxidation drying type and a UV drying type; 3) because the specific gravity of the silicon dioxide is large, the silicon dioxide is easy to generate precipitation in the feed liquid, and therefore, the development of the multipurpose high-performance bronzing adhesive is urgently needed.
