Embodiment 1
[0020] Formula: 53 parts by weight of nylon 6 (PA6), 5.0 parts by weight of toughening agent (EVA), 0.8 parts by weight of compatibilizer (maleic anhydride graft copolymer), 0.3 parts by weight of antioxidant (1010:168=1:1) Parts by weight, coupling agent (γ-(methacryloxy) chloropropyltrimethoxysilane) 1.0 parts by weight, lubricant (TAF) 0.3 parts by weight, glass fiber 40 parts by weight.
[0021] Preparation:
[0022] (1) Mixing of main and auxiliary materials
[0023] Mix and stir the main ingredient PA6 with toughening agent, compatibilizer, antioxidant, coupling agent and lubricant to fully disperse the components;
[0024] (2), melt extrusion
[0025] Put the mixed material into the twin-screw extruder, and at the same time of melt extrusion, introduce glass fiber to melt and extrude, and the melt extrusion temperature is in the range of 240-260°C;
[0026] (3) Granulation and post-cooling, air-drying, pelletizing, sieving, magnetic passing, packaging to obtain the f...
