| titleOfInvention | Polypropylene fiber reinforced oleophylic modification method |
| abstract | The invention belongs to the technical field of material modification, and particularly relates to a polypropylene fiber reinforced oleophylic modification method, which utilizes a molecular self-assembly technology and a chemical graft copolymerization technology to reinforce the oleophylic property of polypropylene fibers. The method comprises the following steps: 1) carrying out sulfuric acid soaking treatment on the raw material polypropylene fiber to obtain microporous polypropylene fiber; 2) carrying out gradient hydrogen peroxide solution soaking treatment on the microporous polypropylene fibers to obtain hydroxyl modified polypropylene fibers; 3) based on dopamine molecule self-assembly, amino modified polypropylene fiber is obtained; 4) based on a chemical graft copolymerization technology, the reinforced oleophylic modified polypropylene fiber is obtained by matching with a silane coupling agent. The invention improves the affinity performance and the storage function of the interface to an organic phase and obviously improves the oleophylic property of the polypropylene fiber by reserving a microporous structure and grafting a hydrophobic hyperbranched polymer on the surface of the polypropylene fiber. |
