Example Embodiment
[0010] The first embodiment provides a green, environmentally friendly, cold-resistant and flexible nylon 66 material, which is composed of the following ingredients in a weight ratio: nylon 66: 75.5%; nylon softener: 15%; compatibilizer: 8%; antioxidant: 1.0%; others Additives: 0.5%.
[0011] Dry nylon 66 first, then weigh it with nylon softener, compatibilizer, antioxidant, and other additives in proportions, then mix at low speed for 10 minutes in the mixer. The mixer uses low speed mixing. The mixing blade should be mixed with the barrel. The wall gap is less than 0.5 cm. The mixing effect of raw and auxiliary materials should be visually uniform for various particles, powders and liquids, without obvious agglomeration or agglomeration; twin-screw extruder uses 40 length-to-diameter ratio, medium strength shear; water-cooled brace Pelletizing method (or underwater pelletizing method), green environmental protection cold-resistant flexible nylon 66 material is prepared after s...
