Abstract:
PURPOSE: A surface reforming of polyolefin or thermoplastic resin using ion assist reaction, method for toughened nylon resin is provided to give compatibility and improve interface adhesive property in manufacturing polyolefin resin, thermoplastic resin and blend of nylon by inducing functional group in polyolefin resin or thermoplastic resin. CONSTITUTION: The surface reforming of polyolefin or thermoplastic resin using ion assist reaction, method for toughened nylon resin is characterized by functionating surface of polyolefin resin powder or thermoplastic resin powder by adding reactivity gas in irradiating ion beam to polyolefin resin or thermoplastic resin powder; blending polyolefin resin powder or thermoplastic resin powder functioned of surface with nylon resin. In this method, quantity of irradiative ion beam ranges from 1*10¬15 to 1* 10¬17ions/cm2, irradiative current density is 2microA/cm¬2, acceleration energy of irradiative ion beam is 1KeV, irradiative ion is oxygen or hydrogen, additive reactivity gas is oxygen and injection quantity of reactivity gas is 0.2-6m/min.
