摘　　要：采用气相色谱-质谱联用(GC-MS)仪和液相色谱(LC)仪分析硫化胶条及其原材料中的挥发性有机物(VOC)的成分。结果表明:硫化胶条的VOC含有苯、甲苯、乙苯、二甲苯、甲醛、乙醛、丙烯醛、二硫化碳、2-甲基丁醛、N,N-二甲基乙酰胺、苯酚;在5种原材料中,发泡剂OB-25和炭黑分别含有苯和甲苯,EPDM和石蜡油均含有苯酚,5种原材料均含有甲醛、乙醛和丙烯醛;在原材料检测中未发现二甲苯、乙苯、二硫化碳和2-甲基丁醛,这4种化合物是胶料在混炼和硫化过程中发生化学反应而生成的。The components of volatile organic compounds(VOC) in the vulcanized rubber strip and its main raw materials were analyzed by GC-MS and LC. The results showed that,VOC of the vulcanized rubber strip and its main raw materials contained benzene,toluene,ethylbenzene,xylene,formaldehyde,acetaldehyde,propylene aldehyde,carbon disulfide,2-methylbutyraldehyde,N,N-dimethylacetamide and phenol. Among the five raw materials,foaming agent OB-25 and carbon black SP5000 contained benzene and toluene respectively,ethylene-propylene-diene rubber(EPDM) and paraffin oil both contained phenol,and the 5 raw materials all contained formaldehyde,acetaldehyde and propylene aldehyde. Xylene,ethylbenzene,carbon disulfide and 2-methylbutyraldehyde were not found in the raw material detection,indicating that these 4 compounds were produced by chemical reaction in the process of mixing and vulcanization.
