摘　　要：研究了防老体系对丁腈橡胶在150℃下3#航空煤油中的防护效果。结果表明,防老体系DDA-70/MBZ/4010NA对丁腈橡胶起到良好的防护效果;适当增大DDA-70和MBZ用量有助于提高防护性能;加入微晶蜡后橡胶耐热油性能变差。Antiaging effect of antiaging system on nitrile rubber was researched in 3# jet fuel at 150℃. The results showed that the antiaging system of DDA-70/MBZ/4OIONA had good antiaging effect to nitrile rubber. The antiaging effect was improved by appropriately increasing amount of DDA- 70/MBZ. The hot-resistant became bad by adding microcrystalline wax.
