| 中文摘要: |
| 用红外光谱法定量分析天然橡胶（NR）/丁苯橡胶（SBR）并用胶。分别选取NR和SBR红外光谱的适宜吸收峰作为定量参比特征吸收峰，建立NR/SBR并用胶的红外光谱定量分析数学模型，所得的NR和SBR用量占比分别与其红外光谱特征峰面积占比呈良好的线性关系。红外光谱定量分析法与裂解-气相色谱法测试NR用量占比的误差和回收率均满足橡胶制品中橡胶并用比的测试要求；红外光谱定量分析法可靠性好，精密度高，且制样简单，操作步骤少，方便快捷。 |
| 英文摘要: |
| In this study，the natural rubber（NR）/styrene-butadiene rubber（SBR） blend was quantitatively analyzed by infrared spectroscopy.The mathematical model was established using respective characteristic absorptions of NR and SBR as quantitative analysis，and it was found that the percentages of NR and SBR in the blend were in good linear relationship with the proportions of the peak area of characteristic absorptions in the infrared spectroscopy spectrum，respectively.Both infrared spectroscopy method and pyrolysis-gas chromatography method showed small measurement error and good recovery rate which met the requirements in analyzing the ratio of certain type of rubber in rubber product.However，infrared spectroscopy method had advantages of good reliability，high precision，simple operation with only a few steps，and quick result. |
