Description

乳化切削液
技术领域
本发明涉及一种乳化切削液及其制备方法，属于润滑油技术领域。
背景技术
切削液是一种在金属切、削、磨加工过程中用于冷却和润滑刀具及加工件的工业用液体，同时具备良好的冷却性能、润滑性能、防锈性能、除油清洗功能、防腐功能以及易稀释等特点。起初工业界使用动植物油作为切削油在加工中作为润滑剂，但动植物油存在很大的缺点就是易变质腐败，使用时间短，成本高。水溶性乳化液具有优良的润滑、防锈、冷却和清洗性能并对提高加工面精度。
但是目前市场上普通的乳化切削液防锈性能一般，稳定性较差，易变质，使用周期短存在诸多的问题。
发明内容
本发明要解决的技术问题是提供一种润滑性、防锈性、清洗性、冷却性好，稳定性佳，不易变质的乳化切削液，以及该乳化切削液的制备方法。
本发明为解决上述技术问题提出的一种技术方案是：一种乳化切削液，包括以下质量百分比的组分：基础油60%～70%，复配添加剂14%～20%，乳化剂0.5%～2%，二壬基萘磺酸钡8%～15%，环烷酸锌1%～3%，十二烯基丁二酸1%～3%，硼砂1%～3%，二烷基二硫代磷酸锌0.2%～1%；所述复配添加剂是由35～45质量份的硼酸、35～45质量份的三乙醇胺、3～8质量份的氢氧化钠反应而成。
所述二壬基萘磺酸钡的用量是10%～12%。
所述基础油的用量是64%～66%。
所述基础油是N10号机械油。
所述乳化剂是非离子表面活性剂。
所述非离子表面活性剂是OP-10和Span-80中的一种或两种。
本发明为解决上述技术问题提出的另一种技术方案是： 一种上述乳化切削液的制备方法，将基础油加入反应釜中，然后加入硼酸和氢氧化钠，升温至90℃～95℃，保温搅拌20分钟～30分钟，再加入三乙醇胺，保温搅拌2小时～3小时，待液体透明后加入乳化剂，搅拌20分钟～30分钟，温度控制在70℃～75℃加入二壬基萘磺酸钡、环烷酸锌、十二烯基丁二酸、硼砂和二烷基二硫代磷酸锌，继续搅拌20分钟～30分钟，混合均匀后即可得到成品。
本发明具有积极的效果：本发明的乳化切削液由基础油、防锈剂、复配添加剂、乳化剂、抗磨剂、防腐剂等混合而成。复配添加剂采用硼酸、三乙醇胺、氢氧化钠反应而得硼酸与氢氧化钠反应生成硼酸钠，硼酸与三乙醇胺反应生成三乙醇胺硼酸酯，具有极好的乳化、润滑和防锈效果，非离子表面活性剂降低乳化液对pH值的依赖性，使得乳化效率高，并且保持较低的表面张力，具有很好的清洗性。二壬基萘磺酸钡代替石油磺酸钡和石油磺酸钠，配以环烷酸锌、十二烯基丁二酸、硼砂等防锈剂，可以有效提升防锈性。硼砂、二烷基二硫代磷酸锌具有抗氧化的作用，同时二烷基二硫代磷酸锌可以作为抗磨剂使用。本发明的乳化切削液具有优良的润滑、防锈、冷却和清洗性能及抗腐败能力，并对提高加工面精度和减少环境污染均有明显效果。克服一般乳化液常见的易变质易生锈的缺点，并能长时间循环使用。本发明的乳化切削液使用时用工业自来水配制成浓度为5%的稀释液，循环使用，并定期添加。该切削液适用于钢、铸铁等多种金属的大多数机械加工方式，包括切削、磨削、钻孔、铰孔等。广泛应用于汽车、摩托车零部件加工及其他机械行业。
