Cold perm process and uv glue used in this process

Abstract

The invention provides a cold ironing technology and UV glue applied to the technology. The technology comprises the steps that 1, the UV glue is printed to the portion, needing cold ironing, of a printed material and the tone and hue of an electrochemical aluminum foil film easy to strip are adjusted according to the hue needed by a product; 2, opposite pressing is conducted on the electrochemical aluminum foil film easy to strip and the printed material so that the electrochemical aluminum foil film easy to strip and the printed material can adhere together through the UV glue; 3, the portions, not adhering to the printed material through the UV glue, of the electrochemical aluminum foil film easy to strip are stripped and an aluminum layer easy to strip of the electrochemical aluminum foil film easy to strip which adheres to the printed material through the UV glue is transferred to the printed material; 4, the UV glue is solidified through illumination of an ultraviolet ray lamp. According to the cold ironing technology and the UV glue applied to the technology, the technology process is simple, the ironing and printing speed is high, and the production efficiency is effectively improved.

Description

technical field

[0001] The invention relates to the field of printing, in particular to a cold stamping process and a UV glue used in the process. Background technique

[0002] With the development of social urbanization, technology, and humanization, the printing industry has developed vigorously. More and more packaging boxes for food, cosmetics, and industrial products need to be printed and finely stamped. In recent years, domestic printing manufacturers have successively introduced and purchased A number of newly developed cold stamping equipment, the cold stamping process can stamp fine lines, and the difference in dots has been well received by the industry. The manifestation of problems such as complex and unstable and high loss costs.

[0003] At present, the domestic cold perm technology mainly adopts two methods: one is the ordinary cold perm self-drying glue matching self-drying cold perm anodized aluminum foil film; the other is to use UV adhesive and UV cold p...

[0024] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0025] see figure 1 , the present invention provides a kind of cold perm technique, comprises the following steps:

[0026] Step 1. Print UV glue on the part of the substrate that needs to be cold stamped, and adjust the color tone and hue of the easy-peelable anodized aluminum foil film according to the color tone required by the product.

[0027] The weight components of the UV glue include: 70-80% polyurethane acrylic resin, 8-15% pure solid acrylic resin, 8-15% photoinitiator and 1-3% auxiliary agent, and, The viscosity of the UV glue is greater than 10Pa.s, and the fluidity is greater than 38mm 3 / s. Wherein, the surface of the substrate printed with UV glue can be: ordinary coated paper, gray-backed white paper, aluminum foil or alumi...
