This invention belongs to the field of polypropylene technology, specifically relating to a high-strength, high-toughness polypropylene material for automotive cable ties and its preparation method.
The material comprises the following raw materials: a first component polypropylene, a second component polypropylene, an antioxidant, and a black masterbatch.
The first component polypropylene is modified polypropylene, and the second component polypropylene is random copolymer polypropylene.
The preparation method includes the following steps:
Material preparation: weighing the raw materials; Premixing: adding the first component polypropylene, the second component polypropylene, the antioxidant, and the black masterbatch into a mixer and mixing to obtain a premix;
Compounding: adding the premix to a twin-screw extruder, melting and extruding to obtain a molten material;
Granulation: drawing, cooling, and cutting the molten material into granules to obtain the polypropylene material.
This invention reduces the amount of additives required, and the resulting material exhibits excellent toughness and strength.
