摘　　要：通过探究针叶木纤维原料的种类以及针叶木纤维与丝光化纤维、聚酯纤维、玻璃纤维的配抄比例,制备出高透气、低孔径的机油滤纸原纸,然后经酚醛树脂浸渍固化得到高耐破度、高纳污容量的机油滤纸.将自制机油滤纸与市售商品机油滤纸(纳污容量130g/m^(2))对比发现:自制机油滤纸的耐破指数较商品机油滤纸高21%,透气度高30%,平均纳污容量高23%左右,接触角高20%;挺度和平均过滤效率略低,相比分别降低6%和5%左右.In this experimental study,the types of softwood fiber and the ratio of softwood fiber to mercerized fiber,polyester fiber and glass fiber were investigated to prepare the oil filter paper with high air permeability and low pore diame-ter,and then the filter paper with high burst resistance and high contaminant capacity was obtained by impregnation andsolidification of phenolic resin.Compared the lab-made oil filter paper with commercial oil filter paper(contaminant capacity 130g/m^(2)),it is found that the bursting index of the lab-made oil filter paper is 21%higher than that of the commercial oil filter paper,the air permeability is 30%higher,the average contaminant capacity is about 23%higher,and the contact angle is 20%higher.Furthermore,it is also found that the stiffness and the average filtration efficiency are slightly lower,which are reduced by 6%and 5%respectively.
