Description

全合成切削液
技术领域
本发明属于金属切削添加剂领域，具体涉及一种全合成切削液。
背景技术
切削液一般是指材料在机械加工过程中，为及时带走切削区内产生的热量以降低切削温度，延长刀具使用寿命，提高工件加工精度而使用的工作液。其通常应具备润滑、冷却、清洗、防锈等作用。切削液按其化学组成可分为油基切削液和水基切削液两大类。油基切削液的润滑性能较好，冷却效果较差。水基切削液与油基切削液相比润滑性能相对较差，冷却效果较好。近年来，由于先进切削机床的不断涌现，刀具和工件材料的发展，对切削液提出了更高的要求。例如，使用硬质合金刀具在高速切削加工时由于产生巨大热量，油基切削液的冷却性能已无法满足需求。使得人们将研究重点转向了研制高性能的水基切削液。
水基切削液具有冷却效果好、可节约能源、操作环境清洁等优点而日渐广泛应用于金属机械加工工艺中，并且有逐步替代油基切削液的趋势。其中尤以水基全合成切削液的优异性更为突出，与传统的乳化油型和半合成切削液相比，全合成切削液由于完全不含机械油，在清洗性、冷却性、加工可视性、抗菌性和稳定性等方面都具有显著地优势，在行业内逐渐获得广泛的应用。然而，现有水基切削液与油基切削液相比，其在防锈性能方面非常不理想。
发明内容

本发明的技术方案是这样实现的：
一种全合成切削液，按照重量百分数计算，包括以下组分：
单一醇胺3～7％、三乙醇胺3～7％、二元酸3～6％、润滑剂11～18％、络合剂3～5％及乳化剂0.5～1％，余量为去离子水。
优选地，所述润滑剂为二聚脂肪酸、聚醚及聚乙二醇的混合物。
优选地，二聚脂肪酸、聚醚及聚乙二醇的质量比为4～7:3～5:4～6。
优选地，所述络合剂选自EDTA、EDTA钠盐、次氮基三乙酸钠、酒石酸钠、柠檬酸钠、葡萄糖酸钠与N-羟乙基乙二胺三乙酸中的一种或者多种。
优选地，所述乳化剂为TX-10。
优选地，还包括消泡剂。
优选地，所述消泡剂的重量百分数含量为0.1～1％。

优选地，所述二元酸优选为十二碳二元酸。
下面对本发明的技术方案作进一步详细说明：
单一醇胺、三乙醇胺及二元酸作为本发明全合成切削液的防锈剂，二聚脂肪酸、聚醚、聚乙二醇起润滑抗磨作用。
本发明的全合成切削液的制备方法为将上述组分混合均匀即可。
本发明的有益效果：
1、本发明的全合成切削液以单一醇胺、三乙醇胺及二元酸作为防锈剂，与其他成分配合，使得本发明的全合成切削液防锈性能达到50天，远大于半合成的切削液的20天。
2、本发明的全合成切削液不含亚硝酸钠、硫、氯、酚、对叔丁基苯甲酸盐等对人体有毒害物质及对环境有害物质，抗微生物能力强,不容易腐败变质,能够有效地延长切削液使用寿命,减少废水排放,有利于环保和清洁生产,提高工作效率，降低加工成本；良好的排污油能力，能将漏入切削液中的导轨油、液压油快速分离出去；良好的铁屑沉降性，避免因过细磨屑(特别是铸铁和球墨铸铁)难于沉降分离，而影响砂轮耐用度和加工精度。
3、本发明的全合成切削液为清澈透明状态,便于观察加工工件,有利于保持加工环境的清洁；储存稳定性好。能适应春夏秋冬不同季节温度的变化；具有优良的润滑性、防锈性、冷却性、清洗性、杀菌性；不破坏油漆，与通常使用的设备密封材料相适应。
