The invention provides a polypropylene modified ternary composite for a plastic geogrid, comprising the following materials according to percent by weight: 10-30% of polypropylene recycled material, 5-15% of fiberglass, and the balance of polypropylene dedicated material. In the production process of the geogrid, the addition of the polypropylene recycled material or regenerated material reduces production investment cost, saves resources, reduces environmental pollution but results in certain negative influence upon mechanical properties of a product; therefore, by means of material modifying at the premise of reduced cost, the mechanical properties of the geogrid material is improved, the geogrid material can meet the practical requirements and has certain theoretical significance and applicable value; the steps are simple, operating is convenient, and practicality is high. 本发明提供一种塑料土工格栅用聚丙烯改性三元复合材料，由如下重量百分比的原料组成：聚丙烯回收料10％～30％；玻璃纤维5％～15％；余为聚丙烯专用料。在土工格栅的生产过程中，聚丙烯回收料或再生料的加入降低了生产投资成本，又节约了资源，减少了环境污染，但会对产品的力学性能有
