Example Embodiment
[0032] Example 1
[0033] A high-performance and low-cost PA-PP alloy whose composition is proportioned by mass percentage: 74% recycled PA6 resin, 25% PP resin, 5% polypropylene grafted maleic anhydride, 0.3% silicone masterbatch, ultrafine Talc 0.3%, antioxidant 10100.4%. Wherein, the recycled PA6 resin is a recycled PA6 resin obtained by crushing, cleaning, separating, drying, and extruding and pelletizing recycled waste nylon carpets. Its relative viscosity is 2.0-2.7 according to Ubbelohde’s viscosity method, where PA6 is Polycaprolactam. The PP resin is polypropylene.
[0034] Preparation method: (1) Dry the regenerated PA6 at 100℃~120℃ for more than 8 hours, dry PP at 90℃~110℃ for more than 2 hours, and then graft maleic anhydride, silicone masterbatch, superfine to polypropylene Talc powder and antioxidant 1010 were dried at 70℃~100℃ for 4 hours; (2) After drying treatment, regenerated PA6, PP, polypropylene grafted with maleic anhydride, silicone masterbatch, ultrafine ...
