Embodiment 1
[0048] An Amorphous Nylon 6 / CaCl 2 Composite material and crystalline nylon 6 / CaCl obtained after post-treatment 2 The composite material is prepared by the following method:
[0049](1) First weigh nylon 6, 40g, and weigh anhydrous CaCl with a volume fraction of 5% 2 (3.81g), anhydrous CaCl 2 Grind to powder in a mortar. Treated anhydrous CaCl 2 With nylon 6, dry in a vacuum oven at 100°C for 12h. Mix Nylon 6 with CaCl in an internal mixer 2 Carry out banbury mixing, wherein the banbury temperature is 260°C, the time is 5min, and the rotor speed is set at 30r / min;
[0050] (2) On a hot press, a series of nylon composite materials obtained in step (1) are calendered into a film, and nylon 6 / CaCl 2 The calendering temperature of the film is 260° C., the pressure is 5 MPa, and the heating time is 10 minutes. Preparation of nylon 6 / CaCl by calendering 2 film;
