Flexible wear-resistant artificial ribbed lawn filament and preparation method thereof

The invention belongs to the technical field of artificial turf manufacturing, and relates to a flexible wear-resistant artificial ribbed lawn filament and a preparation method thereof. The flexible wear-resistant artificial ribbed lawn filament comprises grass ribs and grass leaves, and the grass leaves are evenly distributed on the outer sides of the grass ribs; the grass ribs and the grass leaves both comprise matrix resin, color master batches, a plastic anti-aging agent, a toughening agent, a plastic dispersing agent and a plastic antioxidant. The preparation method of the flexible wear-resistant artificial ribbed lawn filament comprises the steps of raw material melting, raw material mixing, preliminary forming, wire drawing, sizing and rolling, and blending of linear low-density polyethylene and polypropylene. When the polypropylene crystal is broken, the polypropylene crystal is cut into broken crystals, at the moment, a crystal interface between the polypropylene crystal and the linear low-density po
