| 中文摘要: |
| 研究一种未知新型复合橡胶助剂的成分剖析方法。对未知新型复合多功能粉末橡胶助剂进行初步分析后，采用热重分析、红外光谱分析、裂解气相色谱-质谱联用分析、扫描电镜分析、能谱分析和原子吸收光谱分析等现代仪器分析方法对其成分进行剖析，并对测试结果进行综合分析、相互印证。推测该新型复合多功能粉末橡胶助剂为聚乙烯和硬脂酸（盐）改性的碳酸钙粉末，并添加酚类抗氧剂264和活性剂氧化锌或硬脂酸锌。 |

| The composition analysis methods of an unknown novel composite additive were investigated.After a preliminary analysis of the unknown novel composite multifunctional powder rubber additive，its composition was characterized using modern instrumental analysis methods，including thermogravimetric analysis，infrared spectroscopy，pyrolysis gas chromatography-mass spectrometry，scanning electron microscopy，energy dispersive spectroscopy，and atomic absorption spectroscopy.The test results were comprehensively analyzed and cross-validated.It was speculated that the novel composite multifunctional powder rubber additive consisted of calcium carbonate powder modified with polyethylene and stearic acid（or stearate），together with phenolic antioxidant 264 and either zinc oxide or zinc stearate as activators. |
