Problems solved by technology

Such a high service temperature has brought some problems: for example, if the reaction of the coloring layer is not very complete, then its temperature resistance will be relatively poor
When the back adhesive is coated, the solvent in the adhesive can easily seep through the aluminum layer, and erode the paint of the coloring layer and the protective layer, resulting in floating and blooming of the color of the full transfer film, which seriously affects the surface effect of the transfer skin.

Abstract

The invention provides a hot stamping adhesive for leather full transfer film, which comprises: 10-30 polyester resin, 5-15 neoprene resin, 1-5 tackifying resin, and 2-10 inorganic filler in parts by weight , Organic mixed solvent 50-80. The back adhesive has excellent bonding performance to the aluminum layer of the full transfer film and the transfer carrier leather, paper, etc.; the hot stamping temperature is low, and the adhesive has good softening and bonding performance when the hot pressing temperature is 90°C; The polarity of the solvent used is relatively weak, only a small amount of ketone solvent is used, and there is basically no corrosion to the aluminum layer and the colored layer.

Description

technical field [0001] The invention relates to an adhesive, which belongs to an organic polymer heat-activated adhesive, in particular to a hot stamping adhesive for leather full transfer film and a preparation method thereof. Background technique [0002] Leather full transfer film is also called leather hot stamping film, which is the abbreviation of full transfer hot stamping film for leather or full transfer hot stamping film. The full transfer film has a six-layer structure, which are PET film, release agent, protective layer, coloring layer, aluminum plating layer and adhesive layer (such as figure 1 shown). [0003] The leather transfer film is hot-bonded with artificial leather, PU leather and genuine leather by heating and pressing, and the PET film on the surface is peeled off at the same time, so that the coating or pattern on the PET film is completely transferred to the leather surface. The transfer film is combined with the leather by hot pressing to form a ...
