摘　　要：介绍汽车橡胶密封条析出物的测试与分析方法。用裂解气相色谱/质谱分析密封条析出物,用傅里叶红外光谱分析汽车漆板油漆,用模拟试验推测密封条可能析出的配合剂,并对析出风险较大的配合剂进行污染性试验。结果表明,本分析是因橡胶密封条中的促进剂DPG-80析出而导致汽车漆板污染。在密封条析出物分析时应综合考虑析出物在析出过程或测试过程可能会发生二次反应而掩盖其本身结构。In this paper,test and analysis methods on the migrated substances of automotive rubber seal were introduced. The migrated substances were analyzed by pyrolysis gas chromatography/mass spectrometry and the automobile paint was analyzed by Fourier transform infrared spectroscopy. The possible migrating ingredients in seal were then analyzed by simulation test,and pollution test was carried out for the ingredients with high migrating risk. The results showed that the migration of accelerator DPG-80 in seal led to the contamination of automobile painting plate. During the analysis,the possibility that migrated substance could have secondary reactions in the migration process or test process which might change its original structure should be carefully taken into consideration.
