Problems solved by technology

[0003] Three-dimensional hot stamping refers to hot stamping and embossing at one time. Generally, a hot stamping plate and a bottom mold are used to make the printed matter plastically deform under a certain pressure and temperature, and at the same time make the anodized aluminum foil be printed on the printed matter or other substrates. The part where plastic deformation occurs, so as to perform artistic processing on the surface of the printed matter; but in the existing three-dimensional hot stamping process, the adhesion between the hot stamping layer and the subsequent printing layer is poor, and the ink is easy to fall off, which brings inconvenience to practical application

Abstract

The invention discloses a UV flashing three-dimensional pyrography packaging box printing process. During printing, the surface of a packaging box is printed through a process of conducting printing after conducting pyrography. During actual operation, firstly, component selection of an electrochemical aluminum film is adjusted, components such as hydrogen-containing silicone oil, vinyl silicone oil, perfluoroalkyl ethylene and 2- (diethylamino) ethyl methacrylate are selected during preparation, the hydrosilylation effect is generated under the effect of a platinum catalyst (chloroplatinic acid-isopropanol mixed solution), and accordingly, a formed mutually-crosslinked organic silicon release layer has an excellent release demolding effect during use. The process is reasonable in design and appropriate in component ratio, the surface pattern of the prepared packaging box is clear, the printing effect is excellent, the cost is low, the process is simple and easy to operate, the process is suitable for large-scale production and application, the ink printing adhesive force is good, and high practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a packaging box printing process of UV flashing three-dimensional hot embossing. Background technique [0002] With the advancement and development of science and technology, the modern packaging industry is becoming more and more prosperous. In the field of packaging technology, paper, plastic, glass, metal and other materials are generally used for packaging. However, due to the wide range of sources of paper products, low cost, light and easy to carry , so paper packaging has gradually entered our daily life and is considered to be the most potential packaging material. [0003] Three-dimensional hot stamping refers to hot stamping and embossing at one time. Generally, a hot stamping plate and a bottom mold are used to make the printed matter plastically deform under a certain pressure and temperature, and at the same time make the anodized aluminum foil be printed on the pri...
