Problems solved by technology

[0011] In addition, the applicant found that the pattern of the tipping paper hot stamping film is small. In order to save costs, the hot stamping film needs to be cut and stamped multiple times, which is difficult to achieve with the current solvent-based adhesive.
Taking the solvent-based adhesive produced by a certain domestic (Guangdong) manufacturer (hereinafter referred to as Factory B) as an example, it can only be done 6 times, and the customer will generate a lot of waste during use.

Abstract

The invention discloses environment-friendly aqueous thermoprinting back glue for a tipping paper thermoprinting film and a preparation method thereof, wherein the formula thereof comprises the following components in mass ratio: 20 to 60 percent of thermosetting emulsion, 10 to 50 percent of thermoplastic emulsion, 5 to 40 percent of deionized water, 5 to 30 percent of film forming emulsion, 0 to 5 percent of film forming auxiliary agent, 0 to 3 percent of flatting agent, 0 to 3 percent of wetting agent, 0 to 3 percent of defoaming agent and a proper amount of pH control agent. The back glue is prepared by adopting a two-step material mixing method, and excellent product stability and uniformity can be obtained through controlling with different stirring speed and stirring time. A totally aqueous material is adopted by the invention, and balance is comprehensively obtained by utilizing the brittleness of the thermosetting emulsion, the flexibility of the thermoplastic emulsion and the film forming property of the film forming emulsion. According to the invention, zero emission can be realized in the production process, and the environment-friendly aqueous thermoprinting back glue for the tipping paper thermoprinting film, which has zero VOC, high solid content, low viscosity, adaptability for high-speed thermoprinting for many times, clear patterns, no metal flying and good adhesive force can be prepared.

Description

technical field [0001] The invention relates to a water-based back glue for hot stamping or a water-based adhesive and a preparation method thereof, and belongs to the technical field of chemical adhesive preparation. More particularly, the present invention relates to an environmentally friendly tipping paper hot stamping film that can be made into zero VOC (volatile organic compounds), high solid content and low viscosity, suitable for high-speed hot stamping, clear pattern, no "flying gold", and good adhesion. Water-based hot stamping adhesive and its preparation method. technical background [0002] Based on the fact that the anodized aluminum industry currently uses solvent-based adhesives for coating, a large amount of solvent emissions are generated during the production process, which causes great pollution to the environment. Every 10,000 standard rolls (76.8 square meters per standard roll) use 3 tons of adhesive (based on 40% solid content), and the solvent conta...
