Abstract
The invention discloses a large-section irregular concrete reinforced modified polypropylene fiber and a production method thereof. The section of the fiber is flat, the ratio of the length to the width of the section is 3-4:1, and abbatre is arranged on the surface of the fiber. The fiber is prepared from 90-100% of polymer and 0-10% of additives, wherein the polymer is polypropylene, and the additives comprise high melt index PP (polypropylene), maleic anhydride grafted polypropylene and linear polyethylene. The fiber has the advantages of reasonable structure, high strength, good working performance and high tension strength reaching 4-66CN/dtex.
