This invention provides a novel method for preparing anti-fouling nets for marine aquaculture facilities, encompassing the preparation of anti-fouling composite materials, anti-fouling monofilament bundles, and anti-fouling nets. It involves blending filament-grade dried polypropylene pellets, anti-aging agent 1076, UV absorber UV-531, turpentine additive, polyhexamethylene guanidine graft-modified polypropylene material, nano-sized Omeidin copper powder, and nano-copper powder. After thorough mixing, the blend undergoes 3-4 extrusion cycles through a twin-screw extruder to form pellets, yielding the blended anti-fouling composite material. This material is then extruded into filaments. and wound to form anti-fouling monofilament bundles. These bundles were then twisted into Z-twist anti-fouling netting yarn. Using a single-hook netting machine, the yarn was woven into netting sheets. After setting and post-treatment, a novel anti-fouling net for marine aquaculture facilities was obtained.
