Problems solved by technology

At present, the curved wire used in artificial turf is polypropylene curved wire. Polypropylene curved wire has the advantages of high support and convenient processing, but its aging resistance and hand feel are relatively poor. It is used in some outdoor applications or requires a high contact feel. The application cannot meet people's needs

Abstract

The invention discloses an artificial turf bent filament and a preparation method thereof, wherein the artificial turf bent filament comprises the components of 40-95 parts of polyethylene, 5-60 parts of polypropylene, 0.1-2 parts of antiaging agent and 0.01-5 parts of lubricant in parts by weight; the preparation method comprises the steps of 1) preparing the materials: weighing, mixing and melting the materials; 2) extruding: extruding the melt materials into a metering pump; 3) forming a monofilament: quantitatively feeding the materials to a spinning die head through the metering pump, spraying the monofilament, leading the monofilament to a drawing machine; 4) drawing: drawing the monofilament by the draft ratio of 3-6 times; 5) cooling: putting the drawn monofilament in a water bath; 6) preheating: preheating the cooled monofilament through a first heat roller and a second heat roller; 7) air deforming: bending the preheated monofilament for deformation, so as to obtain the artificial turf bent filament. The artificial turf bent filament is soft and comfortable, has a good touch feeling, and has the characteristics of sun block and aging resistance.

Description

technical field [0001] The invention relates to an artificial turf curly wire and a preparation method thereof, belonging to the technical field of industrial chemical manufacturing. Background technique [0002] Artificial turf was born in the United States in the 1960s. It is a artificial lawn made of non-living plastic chemical fiber products as raw materials. Unlike natural turf, it does not need to consume resources such as fertilizers and water necessary for growth. It can meet the needs of high-intensity sports 24 hours a day, and has simple maintenance, rapid drainage, and excellent site flatness. Artificial turf is widely used in special venues for hockey, baseball, and rugby, public practice fields for sports such as football, tennis, and golf, or as ground pavement to beautify the indoor environment. Grass filaments for artificial turf are divided into straight filaments and curved filaments. Curved filaments are generally used in leisure lawns, and can be used t...
