摘要/Abstract

摘要： 利用旋转氧弹和高压差示扫描量热仪，对比探究了烷基吩噻嗪抗氧剂与传统二苯胺抗氧剂对不同类型基础油的感受性；采用混料试验方法，以初始氧化温度、氧化诱导期、旋转氧弹时长为响应，考察了烷基吩噻嗪抗氧剂与其他类型抗氧剂的复配规律。结果表明：烷基吩噻嗪抗氧剂对合成烃类基础油的感受性优于传统二苯胺抗氧剂，但对多元醇酯基础油的感受性相反；在提高油品初始氧化温度和旋转氧弹时长方面，烷基吩噻嗪抗氧剂与胺类抗氧剂L06、L01复配表现出协同效应；在提高油品氧化诱导期方面，烷基吩噻嗪抗氧剂仅与L01有协同作用；而在各种氧化安定性测试中，烷基吩噻嗪抗氧剂与酚类抗氧剂L135复配均表现出拮抗作用。

Abstract: The sensitivity characteristics of alkyl phenothiazine antioxidants in different types of base oils compared with traditional diphenylamine antioxidants were investigated by rotating oxygen bomb test and pressurized differential scanning calorimetry. The compounding pattern of alkyl phenothiazine antioxidants with other types of antioxidants was investigated，using the mixture design method in response to the initial oxidation temperature, oxidation induction period, and rotating oxygen bomb time. The results show that the antioxidant performance of alkyl phenothiazine insynthetic hydrocarbon base oils is better than that of traditional diphenylamine antioxidant,but opposite sensibility for polyol ester base oils. The combination of alkyl phenothiazine antioxidants and amine antioxidants L06 and L01 shows a synergistic effect in improving the initial oxidation temperature and the time of rotating oxygen bomb of oil products. Alkyl phenothiazine antioxidants only have synergistic effect with L01 in improving the oxidation induction time. In different antioxidant tests, the combination of alkyl phenothiazine antioxidant and phenolic antioxidant L135 all showed antagonistic effect.
