preparation example Construction

[0072] The preparation method of the acrylate pressure-sensitive adhesive comprises the following steps: adding an acrylate adhesive, a diluent, a rosin resin A, a rosin resin B, a terpene phenol resin, and a color paste into a reaction kettle, Stir at 800r / min for 1 hour, then add curing agent, continue stirring for 1 hour, let stand to defoam, and obtain acrylate pressure-sensitive adhesive.

[0073] The second aspect of the present invention provides the preparation method of described a kind of polyester film functional material, comprises the following steps:

[0074] (1) The substrate is subjected to biaxial stretching and surface corona treatment, so that the surface tension of the glued surface reaches above 42 dynes / cm;

[0075] (2) Make the non-silicon release agent into a concentration of 0.25-2wt%, and print it on the back of the substrate, so that the release force reaches 20-40g / 25mm;

[0076] (3) Coating the acrylate pressure-sensitive adhesive on the glued sur...
