摘　　要：通过简单的一步浸渍法将硬脂酸(SA)涂覆到具有3D多孔结构的密胺树脂(MF)泡沫表面,制备出可用于油水分离的疏水性泡沫。采用红外吸收光谱仪、扫描电子显微镜(SEM)对SA改性泡沫的结构进行了表征,测试了SA改性泡沫的接触角,并且研究了其对不同油品的吸附性能以及循环使用性能。结果表明:SA成功涂覆到MF泡沫表面上,与水的接触角由0°增加到147°,对不同油品的吸油倍率达到22~30(m/m),并且通过挤压的方式循环使用,说明制备的SA改性泡沫具有良好的疏水性、优异的油吸附能力和循环使用性能。A kind of hydrophobic foam which could be used for oil-water separation was prepared by one-step impregnation method,in which stearic acid(SA)was coated onto the surface of melamine-formaldehyde(MF)foam which has 3D porous structure.The structure of SA modified MF foam was characterized by infrared absorption spectrometer and scanning electron microscopy(SEM).The flame retardancy and contact angle of SA modified MF foam were tested,and the adsorption capacity and the recyclability were studied.The results show that SA is successfully coated on the surface of MF foam.The water contact angle is increased from 0°to 147°,and the oil absorption rate is up to 22-30(m/m)of different kind of oil,and can be recycled by extrusion.It is indicated that the resulting SA modified MF foam has outstanding hydrophobicity,excellent oil adsorption capacity and recycling performance.
