一种高抗冲、低浮纤长玻纤增强聚丙烯材料
摘要：
本发明公开了一种高抗冲、低浮纤长玻纤增强聚丙烯材料，由下述重量百分比的组份构成，长玻纤增强聚丙烯母粒10%～80%，高抗冲、低浮纤母粒20%～90%；所述长玻纤增强聚丙烯母粒的构成为：共聚聚丙烯8%～80%，均聚聚丙烯0～80%，玻纤10%～60%，接枝聚丙烯1%～10%，抗氧剂0.1%～2%，加工助剂0.2%～2%；所述高抗冲、低浮纤母粒的构成为共聚聚丙烯20%～80%，玻纤0～50%，弹性体0～30%，接枝弹性体0～30%，低粘度聚酰胺树脂0～10%，抗氧剂0.1%～2%，加工助剂0.2%～5%。其优点在于，其制备的聚丙烯材料表面光泽高、浮纤现象少，通过材料制造的成品耐跌落性好，加工性能好，可以用于取代工程塑料的相关制件。
摘要（英）：

The invention discloses a high-impact-resistance less-fiber-floating long glass fiber reinforced polypropylene material which is prepared from the following components in parts by weight: 10-80% of long glass fiber reinforced polypropylene master batch and 20-90% of high-impact-resistance less-fiber-floating master batch. The long glass fiber reinforced polypropylene master batch is prepared from8-80% of polypropylene copolymer, 0-80% of polypropylene homopolymer, 10-60% of glass fiber, 1-10% of grafted polypropylene, 0.1-2% of antioxidant and 0.2-2% of processing aid. The high-impact-resistance less-fiber-floating master batch is prepared from 20-80% of polypropylene copolymer, 0-50% of glass fiber, 0-30% of elastomer, 0-30% of grafted elastomer, 0-10% of low-viscosity polyamide resin, 0.1-2% of antioxidant and 0.2-5% of processing aid. The polypropylene material disclosed by the invention has the advantages of high glossiness and less fiber floatings; and the finished product made of the polypropylene material has the advantages of good drop resistance and processability, and can be used for replacing the parts made of engineering plastics.
