Description

一种抗菌性能好的铝合金切削液
技术领域
本发明涉及切削液，具体涉及一种抗菌性能好的铝合金切削液。
背景技术
切削液是一种用在金属切削、磨加工过程中，用来冷却和润滑刀具和加工件的工业用液体，切削液由多种超强功能助剂经科学复合配合而成。
水基切削液可分为乳化液、半合成以及全合成的，通常取决于产品中基础油的类别：乳化液是仅以矿物油作为基础油的水溶性切削液；半合成切削液是既含有矿物油又含有化学合成基础油的水溶性切削液；全合成切削液则是仅使用化学合成基础油(即不含矿物油)的水溶性切削液。
随着十九世纪四五十年代灯用煤油的诞生，人类开始了对石油的开采和使用，到二十世纪石油工业进入到了高速发展时期，矿物油基础油开始逐渐在市场上销售，但是由于其生物降解性差，加之其对环境造成严重的污染，人们必须不断地探索一种绿色环保的基础油来代替矿物基基础油。
发明内容
基于背景技术存在的技术问题，本发明提出了一种抗菌性能好的铝合金切削液。本发明制得的切削液具有优异的润滑性、抗菌性和可降解性。
本发明提出的一种抗菌性能好的铝合金切削液，其原料按重量份包括：基础油30-40份、月桂醇硫酸钠3-8份、聚乙二醇1-3份、三乙醇胺6-8份、硫代硫酸钠1-3份、PH值稳定剂0.5-1份、缓蚀剂0.2-0.5份、异噻唑啉类化合物0.02-0.06份、十二碳二元酸1-3份、消泡剂0.05-0.2份、去离子水9-16份。
优选地，所述基础油包括橄榄油、聚α-烯烃、三羟甲基丙烷酯。
优选地，所述橄榄油、聚α-烯烃、三羟甲基丙烷酯的重量比为1-1.5：0.2-0.6：0.5-0.7。
优选地，所述橄榄油为改性橄榄油，所述改性橄榄油的制备工艺如下：向橄榄油中加入过氧乙酸和催化剂，于65-75℃下反应5-8h，降温至常温，加入纳米氧化锌和偶联剂，搅拌反应2-4h，得到改性橄榄油。
优选地，所述改性橄榄油的制备工艺如下：向橄榄油中加入过氧乙酸和催化剂，于70℃下反应6h，降温至常温，加入纳米氧化锌和偶联剂，搅拌反应3h，得到改性橄榄油。
优选地，所述橄榄油、过氧乙酸、纳米氧化锌的重量比为1：0.5-0.8：0.3-0.5。
优选地，所述催化剂为阳离子交换树脂。
优选地，所述缓蚀剂选自苯骈三氮唑、巯基苯骈噻唑、铬酸钠、硅酸钠中的至少一种。
本发明可按常规方法进行制备。
本发明的原料包括：基础油、月桂醇硫酸钠、聚乙二醇、三乙醇胺、硫代硫酸钠、PH值稳定剂、缓蚀剂、异噻唑啉类化合物、十二碳二元酸、消泡剂、去离子水，各原料之间相容性好，且合理调配原料之间的配比，使本发明能够满足市场对于切削液性能的需求；在优选方案中，本发明的基础油包括橄榄油、聚α-烯烃、三羟甲基丙烷酯，其中，橄榄油的可降解性和润滑性好，具有环境友好性，但分子中不饱和碳碳双键以及β-H的存在使橄榄油的氧化稳定性和低温流动性不好，在本发明的进一步优选方案中，选择过氧乙酸对橄榄油进行改性，对橄榄油中的碳碳双键进行氧化，能够改善橄榄油的氧化稳定性和低温流动性，且在此基础上，能够提高氧化锌与橄榄油的相容性，较好地引入具有除菌作用的氧化锌粒子，有效提高本发明的抗菌性能；聚α-烯烃具有高闪点、高自燃点、低倾点、高粘度指数和挥发性低等特点，同时也具有良好的氧化稳定性和水解稳定性；三羟甲基丙烷酯和天然油脂的结构非常相似，都具有脂基结构，故其具有很好的生物降解性；橄榄油、聚α-烯烃、三羟甲基丙烷酯三者配合作用作为本发明的基础油，不仅三者之间相容性良好，且使本发明具有优异的润滑、抗菌、可降解、氧化稳定等性能，符合高效环保的理念要求。
