舷外机用环境友好润滑油及其生物毒性的研究

利用发光细菌作为受试生物对研制的舷外机用TC-W3环境友好润滑油生物毒性进行了试验研究。试验结果表明以三羟甲基丙烷酯(TMP)为主调制的基础油具有低生物毒性、高润滑性能等优点,而以传统矿物油为主的基础油生物毒性较高,大量添加不利于实现低生物毒性的环境友好指标。润滑油的生物毒性主要取决于其添加剂的生物毒性,而添加剂生物毒性差异很大,合理选用添加剂及其使用比例是研制环境友好润滑油的关键。通过对润滑油基础油和添加剂的筛选及配比试验,成功地研制出低生物毒性、可生物降解的TC-W3环境友好润滑油,经润滑性、生物降解性和生物毒性试验,各项指标均满足设计要求。

Studies on Environmental Friendly Lubricants and its Ecotoxicity for Outboard Engine

The experimental study on ecotoxicity of TC-W3 environmental friendly lubricants for outboard engine was made by applying luminescent bacteria as subjects.The experimental results show that base oil modulated by tri-methylol-propane-ester(TMP) has characteristics of low ecotoxicity and high lubricity.On the contrary,the base oil mainly composed of traditional mineral oil,which has high ecotoxicity can hardly meet the requirement of the indexes of low ecotoxicity if they are massively added.The ecotoxicity of lubricants is mainly decided by the ecotoxicity of additives,which varied dramatically,therefore it is essential to develop ecotoxicity of environmental friendly lubricants by reasonablely using additives and its proper proportion.Low ecotoxicity and biodegradable TC-W3 environmental friendly lubricants was prepared by selecting and proportioning tests to the base oil and additives.The indexes of TC-W3 lubricant meet the requirement of the designation by means of biodegradable and ecotoxicity tests.
