[0053] The present invention also provides the preparation method of the easy-adhesive nylon film described in the above technical solution, comprising the following steps:
[0054] Mix nylon resin, slip agent, opening agent, easy-bonding functional material and antistatic agent, melt and extrude through an extruder to obtain the melt raw materials of the first surface layer and the second surface layer;
[0055] Melting and extruding the nylon resin through an extruder to obtain the melt raw material of the core layer;
[0056] Co-extruding the melt raw material of the first skin layer and the second skin layer and the melt raw material of the core layer and casting to the surface of the chill roll, and after plasma treatment, a nylon base material layer is obtained;
[0057] Mixing the modified water-based hydroxy acrylic resin, nano-silica grafted hyperbranched polymer, ethylene maleic anhydride copolymer, solvent, cross-linking agent and slip agent to carry out cross-linki...
