摘　　要：利用裂解气相色谱研究在不同比例的天然/丁苯(NR/SBR),丁苯/顺丁(SBR/BR)并用胶中炭黑N234的分布情况,及白炭黑在异戊/丁苯(IR/SBR)和丁苯/顺丁(SBR/BR)胶中的分布情况。不同种类的混炼胶所制备的结合胶的裂解气相结果显示:N234在NR/SBR并用胶中优先选择分布在NR中,而在SBR/BR并用胶中优先分布在BR中;而白炭黑在IR/SBR和SBR/BR中均优先选择分布在SBR中。By using pyrolysis gas chromatography, we investigated the distribution of carbon black N234 in NR/SBR and SBR/BR rubber blend with different ratios. And the distribution of silicon in IR/SBR and SBR/BR rubbers was also investigated here. The results of pyrolysis gas chromatography obtained from the bound rubber showed that N234 preferred to distribute in NR as in NR/SBR rubber blend and in BR as in SBR/BR rubber blend; while silicon preferred to distribute in SBR no matter in IR/SBR or SBR/BR rubber blends.
