Embodiment 1
[0029] The acrylic pressure-sensitive adhesive is coated on one side of the base polyester film, as follows:
[0030] 1. Prepare the adhesive mixture, take 100 parts by mass of acrylic ester adhesive SK-1499M (produced by Soken Chemical Co., Ltd.), 3 parts by mass of isocyanate-based hardener HMDI, and 0.1 parts by mass of metal catalyst dilauric acid N-Butyltin, stir well after mixing, take a certain amount for coating, the coating thickness is 10μm, and dry after coating.
[0031] 2. The first section of the oven is set to 70°C for the removal of adhesive solvents, the second section is set to 120°C, and the third section is set to 130°C. These two sections are the curing stage.
[0032] 3. The drying time of the oven is 5min.
[0033] 4. After drying, cool to room temperature, then rewind and slit from the back to prepare protective film tape.
Embodiment 2
