Title
(EN) Anti-floating fiber agent and anti-floating fiber polypropylene reinforced composite material
(ZH) 一种抗浮纤剂和一种抗浮纤聚丙烯增强复合材料
Abstract
(EN) The invention discloses an anti-floating fiber agent and a preparation method thereof. Meanwhile, the invention also discloses an anti-floating fiber polypropylene reinforced composite material. The anti-floating fiber polypropylene reinforced composite material comprises the following components in parts by weight, 35-90 parts of polypropylene, 20-50 parts of glass fibers, 5-15 parts of the anti-floating fiber agent and 0.2-0.6 part of an antioxidant, the polypropylene comprises polypropylene A, and the melt flow rate of the polypropylene A at 230 DEG C and 2.16 kg is 1000-1500g/10min. By using the polypropylene A and the anti-floating fiber agent, the glass fiber can be better wrapped and infiltrated, so that the appearance anti-floating fiber effect is good; in addition, the invention also discloses a preparation method of the anti-floating fiber polypropylene reinforced composite material.
(ZH) 本发明公开一种抗浮纤剂及其制备方法；同时，本发明还公开一种抗浮纤聚丙烯增强复合材料，包括如下重量份的成分：聚丙烯35～90份、玻璃纤维20～50份、抗浮纤剂5～15份和抗氧剂0.2～0.6份，所述聚丙烯中包含有聚丙烯A，所述聚丙烯A在230℃、2.16kg下的熔体流动速率为1000～1500g/10min。本发明通过使用聚丙烯A及抗浮纤剂，能更好的包裹、浸润玻纤，使得外观抗浮纤效果好；此外，本发明还公开一种所述抗浮纤聚丙烯增强复合材料的制备方法。
