摘要：

为高效经济地处理油品泄漏引起的污染问题,利用聚丙烯(PP)与乙烯-辛烯共聚物(POE)共混后制备复合熔喷非织造材料,然后在其表面负载纳米氧化铜(CuO)进行疏水改性。对改性前后非织造材料的形貌、结构、水接触角、吸油和力学性能等进行测试。结果表明:负载纳米CuO后,CuO/PP/POE复合熔喷非织造材料的结晶度下降,熔融和结晶温度无明显变化,水接触角下降约1°,亲水性略有上升;相对于纯PP非织造材料,负载纳米CuO后复合熔喷非织造材料的吸油率得到提高,添加POE质量分数为15%的熔喷非织造材料对机油的吸油率最高达9.22 g/g,对硅油的吸油率最高达9.4 g/g,且其断裂强力增加,但断裂伸长率降低。

Abstract:

In order to efficiently and economically deal with the pollution caused by oil leakage, the melt-blown nonwoven materials (MB) was prepared by the blending of polypropylene (PP) and ethylene-octene copolymer (POE). The surface of the composite melt-blown nonwoven material was loaded with nano-copper oxide (CuO) for hydrophobic modification. The morphology, structure, water contact angle, oil absorption and mechanical properties of the nonwovens before and after modification were tested. The results show that the deposition of nano CuO causes the crystallinity of CuO/PP/POE composites to decrease, but no significant change in the melting and crystallization temperatures. In addition the deposition of nano CuO resulted in about 1°decrease in the water contact angle, and the hydrophilicity increases slightly. Compared with the pure PP nonwovens, the oil absorption rate of the composite melt-blown nonwovens loaded with nano-CuO is improved. The oil absorption rate of melt-blown nonwovens with POE content of 15% is up to 9.22 g/g for machine oil and 9.4 g/g for silicone oil, and the longitudinal fracture strength is increased, but the elongation at break is decreased.

Key words: polypropylene, ethylene-octene copolymer, melt-blown nonwoven material, copper oxide, oil absorption efficiency, oil water treatment
