Embodiment 1
[0010] Embodiment 1 provides a cold-resistant super-tough nylon 6, which is composed of the following components by weight: nylon 6: 78.5%; cold-resistant agent: 12%; impact modifier: 8%, antioxidant: 1.0%; other additives Agent: 0.5%.
[0011] First dry nylon 6, cold-resistant agent and impact modifier at 85 degrees and 60 degrees respectively, then weigh them with antioxidants and other additives according to the proportion and mix them in the mixer at low speed for 10 minutes. The mixer adopts Low-speed mixing, the gap between the mixing blade and the cylinder wall should be less than 0.5 cm, the mixing effect of raw and auxiliary materials should be visually uniform, and the various particles and powders should be basically uniform without obvious agglomeration or aggregation; the twin-screw extruder uses 40 aspect ratio, medium strength shear Cutting; the water-cooled strip cutting method is adopted, and the cold-resistant super-tough nylon 6 material is obtained after sc...
