Description

Adhesive coating system of PET printing film {ADHESIVE COATING SYSTEM OF PET PRINTING SYSTEM}

The present invention relates to a pressure-sensitive adhesive coating system for a PET printing film, and more particularly, to a pressure-sensitive adhesive coating system for a PET printing film implemented to effectively apply the pressure-sensitive adhesive to one side of a PET printing film.

Recently, the use of sticker-type surface finishes such as interior/exterior materials, interior materials, and advertisement materials of buildings to which pressure-sensitive adhesive (PSA) is applied is increasing significantly. As the adhesive, existing oil-based adhesives cause symptoms such as headache, irritation of the eyes and nose, cough, itchiness, dizziness, fatigue, and decreased concentration in people living inside buildings because residual solvents are discharged into the air for a long period after construction. When exposed for a long period of time, problems of sick house syndrome, which cause respiratory disease, heart disease, and cancer, occur.

For this reason, interest in water-based emulsion adhesives that are environmentally friendly and do not discharge harmful substances to the human body by using water as a dispersion medium is rapidly being replaced. The aqueous emulsion adhesive can use a polymer having a higher molecular weight than a solvent-based polymer, regardless of the viscosity of the adhesive and the molecular weight of the dispersion polymer, and can obtain a wide range of solids concentration, and have low aging resistance, low viscosity, and low viscosity. It has the advantage of good adhesion in the solid content area and good compatibility with other polymers.

However, since water is used as a solvent, the drying speed is slow, the adhesiveness to the hydrophobic adhesive surface, the non-porous adhesive is low, the selection range of the curing agent is narrow, and the initial adhesive strength is poor. And since it contains a dispersing agent, there is a problem that the water resistance is low, and thus the physical properties of the oil-based adhesive cannot be reached.

In the case of such a pressure-sensitive adhesive, it is not easy to apply it to a PET printing film, so a method of applying it to a PET printing film is required.

On the other hand, the above-described background technology is technical information that the inventor possessed for derivation of the present invention or acquired during the derivation process of the present invention, and is not necessarily a known technology disclosed to the general public prior to filing the present invention. .
