| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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，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. |
