摘 要: 在深入剖析铝材轧制工艺润滑特性的基础上， 采用可生物降解的材料， 通过对其多种复配机理的研究， 研制了一种绿色环保型的CSAQ铝材轧制润滑添加剂。 通过四球试验机、 TG和DTA热分析、 兼容性试验及其它理化分析方法对CSAQ添加剂进行了性能测试， 结果表明： CSAQ添加剂具有优良的润滑性、良好的热稳定性和退火清洁性， 且与多种基础油和添加剂兼容。 急性毒理试验表明： CSAQ添加剂测不出LD50， 小鼠每日最大耐受量为80mL/kg。 因此， 其毒性极其轻微， 对人体和环境无毒害作用， 符合德国WGK的标准， 为绿色润滑添加剂。 在工业实际应用中效果良好， 可满足现代高速铝材轧机对润滑添加剂的性能要求。

Abstract:On the base of deep analysis of lubricating character of rolling aluminum, the CSAQ environmental friendly lubricating additive was developed, which was made from complex compound of biodegradable materials such as fatty alcohol, fatty ester, synthetic ester, anti-wear agent and antioxidant agent. The analysis of additive properties, including PB(the four balls method), TG-DTA, compatibility and other physical-chemical properties was carried out. The results indicate that CSAQ additive possesses excellent lubrication, thermal stability, annealing cleanness, and good compatibility with other additives and various base oils. Moreover, acute toxicity tests of CSAQ additive show nonexistence of LD50 and ig dosage of daily maximum tolerance intake of 80mL/kg. Therefore, CSAQ additive is of both less poison and security as well as an environmental friendly lubricating additive according to Germany WGK standard. It was successfully applied to rolling aluminum operation in practice, which achieved the satisfying result.
