Embodiment 1
[0020] A PET release film applied to OCA glue, comprising the following components in parts by mass: 3 parts of D120 solvent naphtha, 8 parts of D30 solvent naphtha, 4 parts of butanone, 2 parts of isopropanol, 0.5 parts of silicone oil main agent, 0.6 parts of heavy stripping additive, 0.05 parts of crosslinking agent, 0.01 part of anchoring agent, and 0.02 parts of catalyst.
[0021] The production process of the above-mentioned PET release film applied to OCA glue comprises the following steps:
[0022] 1) Coating configuration Mix D120 solvent oil, D30 solvent oil, methyl ethyl ketone and isopropanol, stir at 1200 rpm for 30 minutes, filter with a 200-mesh filter, and use within 3 hours;
[0023] 2), the original film treatment includes corona treatment and dust removal treatment; the corona value is greater than 50 during the corona treatment, and the gap between any two points is guaranteed to be no more than 5; thereby enhancing the adhesion of the film surface; the Th...
