Graphene modified polypropylene crude fiber and preparation method thereof
The invention relates to the technical field of polypropylene modified fibers, and particularly discloses a graphene modified polypropylene crude fiber and a preparation method thereof. The crude fiber comprises a skin layer and a core layer wrapped inside the skin layer, wherein the core layer is made of polyformaldehyde and accounts for 20%-80% of the diameter of the finished fiber, and the skinlayer accounts for 20%-80% of the diameter of the finished fiber; the crude fiber comprises the following components of, in parts by weight, 50-250 parts of polypropylene resin, 0.5-5 parts of graphene, 1-10 parts of polyvinylpyrrolidone, 0.1-1 part of liquid paraffin, 1-15 parts of wollastonite powder, 0.1-0.5 part of an antioxidant, and 0.1-0.5 part of an ultraviolet light absorber; and the crude fiber is obtained mainly by two steps of blending and granulating graphene modified polypropylene, and spinning and extruding after master batch and polyformaldehyde melting respectively. The modified fiber has the advantages of being good in graphene dispersity and high in fiber strength.
本申请涉及聚丙烯改性纤维技术领域，具体公开了一种石墨烯改性聚丙烯粗纤维及其制备方法，该粗纤维包括皮层和包覆于皮层内的芯层，所述芯层采用聚甲醛且占成品纤维直径20‑80%，所述皮层占成品纤维直径20‑80%，且包括如下重量份数的组分：聚丙烯树脂：50‑250份；石墨烯：0.5‑5份；聚乙烯吡咯烷酮：1‑10份；液体石蜡：0.1‑1份；硅灰石粉：1‑15份；抗氧化剂：0.1‑0.5份；紫外线吸收剂：0.1‑0.5份。粗纤维主要由石墨烯改性聚丙烯共混造粒、母粒和聚甲醛分别熔融后纺丝挤出两步得到。本申请中的改性纤维具有石墨烯分散性好、纤维强度高的优点。
