摘 要: 在深入剖析鋁材軋制工藝潤滑特性的基礎(chǔ)上， 采用可生物降解的材料， 通過對其多種復(fù)配機(jī)理的研究， 研制了一種綠色環(huán)保型的CSAQ鋁材軋制潤滑添加劑。 通過四球試驗(yàn)機(jī)、 TG和DTA熱分析、 兼容性試驗(yàn)及其它理化分析方法對CSAQ添加劑進(jìn)行了性能測試， 結(jié)果表明： CSAQ添加劑具有優(yōu)良的潤滑性、良好的熱穩(wěn)定性和退火清潔性， 且與多種基礎(chǔ)油和添加劑兼容。 急性毒理試驗(yàn)表明： CSAQ添加劑測不出LD50， 小鼠每日最大耐受量為80mL/kg。 因此， 其毒性極其輕微， 對人體和環(huán)境無毒害作用， 符合德國WGK的標(biāo)準(zhǔn)， 為綠色潤滑添加劑。 在工業(yè)實(shí)際應(yīng)用中效果良好， 可滿足現(xiàn)代高速鋁材軋機(jī)對潤滑添加劑的性能要求。

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.
