摘要
利用等离子技术刻蚀丙纶无纺布,疏水偶联剂辛基三氯硅烷进行化学相沉积修饰降低其表面能,制备出超疏水亲油的丙纶材料。运用正交试验对等离子体处理工艺进行优化,通过扫描电镜表征优化工艺后的丙纶形貌,测试了丙纶的比表面积、吸油时间及循环使用性能。结果表明,等离子体处理的优化工艺为:车速5.4m/min,放电电压24kV,作用间距2.4mm,辛基三氯硅烷化学相沉积修饰添加比占无纺布质量分数的28%。测得此无纺布的静态接触角为155.3°吸油率49.30g/g、吸油饱和时间7s,脱油再生重复使用10次后,还有较高的吸油性能,吸油仍高达45.90g/g。
The surface of polypropylene non-woven fabric was etched by plasma technology,and then modified by hydrophobic coupling agent octyltrichlorosilane through chemical phase deposition to reduce its surface energy,and a super hydrophobic-oleophylic polypropylene fiber material was prepared.The plasma treatment process was optimized by orthogonal experiment.The morphology of polypropylene fiber after optimization was characterized by scanning electron microscope.The specific surface area,oil absorption time and recycling performance of polypropylene fiber were tested.The results show that the optimized process of plasma treatment is:vehicle speed of 5.4 m/min,discharge voltage of 24 kV,action interval of 2.4 mm,and octyltrichlorosilane mass fraction 28%.The measured static contact angle is 155.3°,the oil absorption rate is 49.30 g/g,the oil absorption saturation time is 7 s,and the oil absorption performance is still high after 10 times of oil removal and regeneration,and the oil absorption is still up to 45.90 g/g.
