一种玻纤增强聚丙烯复合物及其制备方法
摘要：
本发明公开了一种玻纤增强聚丙烯复合物，其特征在于，包括以下组分及其重量百分数含量：聚丙烯24‑78％，热稳定剂0‑2％，加工助剂0‑2％，成核剂0‑2％，相容剂2‑10％，短切玻璃纤维A10‑30％和短切玻璃纤维B10‑30％；短切玻璃纤维A的直径为14微米，短切玻璃纤维B的直径为7微米。本发明还公开了一种玻纤增强聚丙烯复合物的制备方法。与现有技术相比，本发明采用14微米直径短切玻璃纤维和7微米直径短切玻璃纤维为原材料，既显著提升了现有玻纤增强聚丙烯的性能，又保持了一个良好的性价比。
摘要（英）：

The invention discloses a glass fiber-reinforced polypropylene compound, which is characterized in that the compound comprises the following components by weight percent: 24 to 78 percent of polypropylene, 0 to 2 percent of heat stabilizer, 0 to 2 percent of processing agent, 0 to 2 percent of nucleating agent, 2 to 10 percent of compatilizer, 10 to 30 percent of chopped glass fiber A and 10 to 30 percent of chopped glass fiber B; the diameter of the chopped glass fiber A is 14 microns, and the diameter of the chopped glass fiber B is 7 microns. The invention also discloses a preparation method of the glass fiber-reinforced polypropylene compound. Compared with the prior art, the 14-micron-diameter chopped glass fiber and the 7-micron-diameter chopped glass fiber are adopted as raw materials, so that not only is the property of the existing glass fiber-reinforced polypropylene remarkably improved, but also a good cost performance is kept.
