摘要/Abstract

摘要： 探索了复合钡基润滑脂的制备工艺，制备出滴点较高的复合钡基润滑脂。利用差热扫描量热(DSC)、X射线衍射(XRD)、傅里叶变换红外光谱(FTIR)及扫描电子显微镜(SEM)等方法研究复合钡基润滑脂的滴点和共晶聚集态。结果表明：癸二酸复合12-羟基硬脂酸钡基润滑脂的滴点比癸二酸复合硬脂酸钡基润滑脂的滴点高；癸二酸复合12-羟基硬脂酸钡基润滑脂的稠化剂分子间形成了氢键，导致稠化剂内部形成了共晶结构。

关键词: 复合钡基润滑脂, 滴点, 氢键, 共晶

Abstract: The synthetic methods of complex barium greases with high dropping points were explored. DSC, XRD, FTIR and SEM were used to study the relationship between dropping points and crystalline aggregation of thickeners in complex barium greases. The results revealed that the dropping point of complex barium hydroxystearate greases with sebacic acid was higher than that of barium stearate greases with sebacic acid due to the hydrogen bonds formed between hydroxyl group (-OH) of 12-hydroxystearate and carbonyl group (C=O) of sebacic acid within complex barium hydroxystearate grease thickeners, resulting in the cocrystallization structure created inside the thickeners.

Key words: complex barium grease, dropping point, hydrogen bond, cocrystallization
