摘要：以航空汽油(马达法辛烷值(MON)为93.7)为基础油,加入芳胺类抗爆剂调配出95号和100号无铅航空汽油。采用环块实验测量发动机40Cr金属材料的磨痕长度,评价航空汽油对发动机排气阀阀座等金属材料抗磨性的影响,并测量经汽油浸泡后橡胶试样所发生的外观、质量变化以考察油品对燃油管路中密封所用橡胶部件溶胀作用的程度。依上述实验结果,分析辛烷值相近的无铅芳胺汽油与加铅汽油在抗磨性、溶胀性上的差异。结果表明,加芳胺无铅航空汽油的抗磨性、溶胀性均较辛烷值相近的加铅汽油差,而在加芳胺类抗爆剂的无铅航空汽油中添加抗氧剂可抑制其对橡胶制品的溶胀作用,减弱发动机中相应部件受到溶胀作用的影响。
Grade 95 and 100 unleaded aviation gasolines were obtained by adding aromatic amine anti- knock agent in a blank aviation fuel with MON of 93.7. The differences on abrasion resistance of metal in seat and swelling property of sealing element between unleaded aviation gasoline added aromatic amines and leaded fuel with similar MON number were analyzed by measuring the length of grinding crack of 40Cr metal by ring-on-block experiments and observing mass and volume changes of rubber samples after soaked in gasoline. The results indicate that gasoline with aromatic amines shows worse performance on abrasion resistance and swelling property than leaded gasoline. Anti-oxidants may be employed in aromatic amines added aviation gasoline for weakening the swelling effect on rubber products.
