The invention provides an oil-resistant synthetic rubber, which is prepared from the following components in parts by weight: 90 to 110 parts of ACN19-41 nitrile butadiene rubber, 61 to 75 parts of afilling agent, 24 to 30 parts of a plasticizer, 5 to 7 parts of an active agent, 0.9 to 1.1 parts of a dispersing agent, 0.5 to 0.7 part of a vulcanizing agent, 2.3 to 2.9 parts of an anti-aging agentand 3.8 to 4.7 parts of an accelerant. The oil-resistant synthetic rubber can be used for sealing elements in various stages of dimethyl ether storage, transportation, use and the like, has the advantages of aging resistance and low cost, and adopts nitrile butadiene rubber with good oil resistance as the raw rubber, so that the rubber disclosed by the invention also has good lubricating oil resistance. 本发明提供一种耐油合成橡胶，由以下重量份的成分组成：ACN19-41丁腈橡胶90-110份、填充剂61-75份、增塑剂24-30份、活性剂5-7份、分散剂0.9-1.1份、硫化剂0.5-0.7份、防老剂2.3-2.9份和促进剂3.8-4.7份。本发明可用于二甲醚、贮藏、输送、使用等各个阶段的密封件，不易老化，且成本低廉。另外，由于本发明的原胶采用具有良好耐油性能的丁腈橡胶，因此，本发明亦具有较好的耐润滑油性能。
