摘　　要：以水性酚醛树脂为研究对象,对经其浸渍后的滤纸在汽油和柴油中的强度性能保持率及孔径大小的变化进行研究。结果表明,滤纸经水性酚醛树脂增强后,强度性能较苯丙乳液增强后滤纸有明显改善,且表现出优异的耐油性能;水性酚醛树脂增强滤纸在汽油和柴油中浸泡5天后,耐破度保持率都达到88%以上,其他强度性能保持率也较高,虽然孔径随着浸泡时间延长呈现逐渐增大的趋势,但总体变化不大。In this paper,a kind of water-soluble phenolic resin and its enhanced paper were studied,and the paper＇s mechanical strength retention and the change of porosity structure in gasoline and diesel were investigated.The mechanical strength of the filter paper impregnated with the resin is better than that of the filter papers impregnated with three kinds of styrene-acrylic.Its oil resistance and porosity structure stability are also very good.Its burst index retention is more than 88% after five days and the porosity structure is not changed very much,which shows that phenolic resin has a better compatibility in all of the fuel media studied.
