Method for producing surface-modified fluororesin film/thermoplastic resin composite |
摘要 |
The present invention aims at providing a composite of a surface-modified fluororesin film and a thermoplastic resin bonded to each other, and medical equipment containing the composite. A method for producing a fluororesin/thermoplastic resin composite includes roughening a surface of a fluororesin film by ion beam irradiation from an ion source, and pressure-bonding the surface-modified fluororesin film obtained in the surface roughening step and a thermoplastic resin while maintaining the thermoplastic resin in a fluid state. |

1. A method for producing a fluororesin/thermoplastic resin composite, the method comprising:
roughening a surface of a fluororesin film with anode layer ion beam irradiation from an anode layer ion source to which a voltage of not less than 1.5 kV but not more than 3.5 kV is applied one time; and pressure-bonding the surface-modified fluororesin film obtained in the surface roughening step and a thermoplastic resin under a pressure of not less than 1 MPa while maintaining the thermoplastic resin in a fluid state, wherein the fluororesin film comprises a fluororesin selected from polytetrafluoroethylene and modified polytetrafluoroethylene, wherein the thermoplastic resin is selected from the group consisting of polypropylene resins, cycloolefin resins, styrene resins, olefin elastomers (TPO) which include an olefin resin and uncross-linked rubber phases of an ethylene-propylene polymer, and TPE-V which includes an olefin resin and cross-linked rubber phases of an ethylene propylene diene polymer. |
