聚烯烃树脂、其制备方法及使用其的车辆后保险杠梁
本发明涉及一种聚烯烃、其制备方法及使用其的车辆后保险杠梁，并提供了：由热塑性树脂复合材料形成的聚烯烃树脂，该热塑性树脂复合材料包括含有多分散性指数为2‑10的丙烯均聚物和着色剂的聚合物基体，和具有5‑20mm的长度并浸渍到聚合物基体中的纤维增强试剂，其中聚烯烃树脂表现出改善的机械性质和高冲击强度，同时由于在聚烯烃树脂的基础上包含10‑50wt％的纤维增强试剂而保持低比重；制备其的方法；和能够通过使用聚烯烃树脂来注射模制的车辆后保险杠梁，从而最小化制造成本，以及保证尺寸和性能稳定性，从而满足低速碰撞规定性能。
The present invention relates to a polyolefin, a method for preparing the same, and a vehicle rear bumper beam using the same, and provides a polyolefin resin which is composed of a thermoplastic resin composite including a polymer base including a polypropylene homopolymer, which has a molecular weight distribution of 2 to 10, and a colorant, and a fiber reinforcing material that is impregnated into the polymer base and has a length of 5 to 20 mm, 10 to 50 wt% of the fiber reinforcing material being included with respect to the polyolefin resin, and which is thus able to maintain a low specific gravity while exhibiting improved mechanical properties and high impact strength, a method for preparing the same, and a vehicle rear bumper beam that can be injection-molded using such a polyolefin resin, thus minimizing production costs, and which achieves dimensional and performance stability, and thus can satisfy legally mandated low-speed crash performance.
