| titleOfInvention | Processing method of high-performance PET release film |
| abstract | The invention discloses a processing method of a high-performance PET release film, which comprises the following steps of selecting raw materials; step two, treating the original membrane; step three, coating corona; step four, drying and curing; step five, rolling the film for storage; in the first step, a PET substrate layer with smooth surface, high transparency, small haze, no impurity and good scratch resistance is manually selected; according to the processing method of the high-performance PET release film, the PET substrate layer is used as a raw material, the mixed liquid of sodium permanganate, ferric sulfate, ethylene glycol monomethyl ether, polyurethane resin and ethyl acetate is added, corona processing is carried out to obtain the high-performance PET release film, the process is simple, the product efficiency is high, the stability and the adhesive force of the PET release film are improved, the heat shrinkage rate is reduced, the performance of the PET release film is greatly improved, meanwhile, toxic substances and pollution are avoided, the environment is protected, the high-performance PET release film can replace other expensive PET release film production processes, the raw material is cheap, the cost is low, and the production cost is greatly saved. |
