[0002] Geogrid is a major geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement for reinforced soil structures or reinforcement for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids, and polyester warp-knitted polyester geogrids. Geogrids are two-dimensional grids or three-dimensional grid screens with a certain height made of high molecular polymers such as polypropylene and polyvinyl chloride through thermoplasticization or molding. When used in civil engineering, they are called geogrids.
[0003] Existing geogrids, such as a carbon-plastic composite modified geogrid disclosed in the patent with announcement number CN104311958A, are processed from the following component raw materials in parts by weight: 80-90 parts of high-density polyethylene, 10-20 parts of PVC resin, 5-10 parts of carbon fiber, 0.1-0.2 parts of antioxidant B215, 0.1-0.2 parts of phosphate triester, 0.2-0.4 parts of zinc stearate, 0.1-0.3 parts of absorbent UV-531, 8-12 parts of carbon black, and 3-5 parts of modified carbon black masterbatch. The formulated materials are mixed and extruded, and the melt is formed into a sheet by a three-roll calender, and the sheet is punched by a punching machine, and the orifice plate is stretched after heating to obtain a geogrid. In this scheme, the tensile performance is poor.
