Abstract
本发明公开了一种镁合金板带材轧制乳化液及其制备方法，涉及润滑剂及镁合金板带材轧制领域。本发明选择季戊四醇油酸酯、三羟甲基丙烷混合酸酯和PAO‑10作为基础油，TX‑4和TX‑7作为乳化剂，硬脂酸丁酯和C12~14醇作为油性剂，磷酸酯和含氮硼酸酯作为极压剂，三乙醇胺、脂肪酸烷基醇酰胺作为防锈剂，乳化硅油作为消泡剂，苯基化萘胺作为抗氧剂，制备具有润滑、防锈、清洗、环保并可循环使用的镁合金板带材轧制乳化液，减少板带表面黏着造成的损伤，降低产品边角开裂情况，清洗掉轧制过程中产生的大量镁粉，有效提高产品表面质量和尺寸精度，同时降低了企业生产成本。
Description
技术领域
本发明属于轧制板带材加工润滑技术领域，具体涉及镁合金板带材轧制的乳化液及其制备方法。
背景技术
镁合金作为迄今为止在实际应用中最轻的金属结构材料，在汽车、航空航天、电子电路领域得到越来越广泛的应用。板带轧制是镁合金最主要的变形方式之一，但是对于镁合金轧制润滑领域的研究却相对较少。
镁合金板带材在轧制过程中，由于轧辊与轧件之间的摩擦，出现“黏镁”现象，不仅浪费能源，还降低轧制速度。此外，镁在高温下易氧化，而镁合金一般采用中温轧制，轧制温度一般在250～400℃易被氧化的温度范围，给镁合金的润滑增加了困难。轧制润滑技术有助于防粘降摩、降低轧制消耗和改善轧后产品表面质量等优点，还可以控制和改善晶粒组织等作用。目前大多数镁合金板带生产企业在生产过程中不采用任何润滑剂，直接干轧，但会引起板带材表面质量差、厚度不均、边缘开裂等缺陷；如果选用全油型润滑液，虽然润滑性和防锈性较好，但是冷却效果较差，易发生轧件黏辊等不良影响；同时润滑油对板带材表面污染严重，生产过程中产生的大量镁粉颗粒，并造成巨大的能源浪费，同时轧辊的隔绝保温作用不够理想，轧制温度不够稳定，因此，需要开发一种油水分散均匀的乳化液。
发明内容
本发明的目的是提供一种镁合金板带材轧制乳化液及制备方法，不仅润滑性能、防锈抗氧性能优良，同时能够清洗轧制过程中产生的大量镁粉颗粒，提高镁合金板带材的表面质量；还能利用乳化液的“离水展着性”使油份吸附在轧辊表面，起到隔绝保温的作用，稳定轧制温度，降低轧辊的“黏镁”程度，同时同时轧制乳化液能够减少轧制能耗，提高生产成品率，并且可循环使用且使用周期较长，降低企业生产成本。
本发明通过下述技术方案予以实现：镁合金板带材轧制乳化液选择季戊四醇油酸酯、三羟甲基丙烷混合酸酯和PAO-10作为基础油，TX-4和TX-7作为乳化剂，硬脂酸丁酯和C12～14醇作为油性剂，磷酸酯和含氮硼酸酯作为极压剂，三乙醇胺、脂肪酸烷基醇酰胺作为防锈剂，乳化硅油作为消泡剂，苯基化萘胺作为抗氧剂。
镁合金板带材轧制乳化液的具体组分及所占重量百分比如下。
| 序号 | 组分名称 | 重量百分比(％) |
| 1 | 季戊四醇油酸酯 | 6.0～10.0 |
| 2 | 三羟甲基丙烷混合酸酯 | 6.0～10.0 |
| 3 | PAO-10 | 3.0～6.0 |
| 4 | TX-4 | 0.1～0.4 |
| 5 | TX-7 | 0.1～0.4 |
| 6 | 硬脂酸丁酯 | 0.5～1.0 |
| 7 | C12～14醇 | 0.3～0.8 |
| 8 | 磷酸酯 | 0.1～0.5 |
| 9 | 含氮硼酸酯 | 0.1～0.5 |
| 10 | 三乙醇胺 | 0.1～0.5 |
| 11 | 脂肪酸烷基醇酰胺 | 0.1～0.5 |
| 12 | 乳化硅油 | 0.005～0.05 |
| 13 | 苯基化萘胺 | 0.1～0.5 |
| 14 | 去离子水 | 75.0～80.0 |
在具体成分中，乳化剂TX-4和TX-7的复配重量比例范围为0.8～1.2，油性剂硬脂酸丁酯和C12～14醇的复配重量比例范围为0.8～2.0，极压剂磷酸酯和含氮硼酸酯的复配重量比例范围为：0.5～1.2，防锈剂三乙醇胺和脂肪酸烷基醇酰胺的复配重量比例范围为：0.5～1.0。
上述镁合金板带材轧制乳化液的制备步骤为：
为避免各类添加剂之间的相互反应影响各自的效果，乳化液各成分的加入具有特定的次序。
1、将上述配方量的油性剂、极压剂、防锈剂、抗氧剂按先后顺序加入超声波分散器中混合均匀，得到混合添加剂；
2、将基础油和步骤1得到的混合添加剂加入反应釜中，在转速为100～140r/min下边加热边搅拌至60～85℃，恒温搅拌时间为25～45分钟，然后冷却至35～45℃保温10～15分钟；
3、搅拌结束后，将消泡剂加入反应釜中，再向其中加入配方量TX-4和TX-7，加热至50～70℃恒温搅拌15～25分钟，冷却至室温，得到镁合金板带材轧制基础乳化油；
4、将步骤3得到的轧制基础乳化油放入超声波分散器中，进行超声分散，再将配方量去离子水缓慢加入，加热至55～75℃恒温搅拌20～40分钟，最终得到乳白色均匀液体，即镁合金板带材轧制乳化液。
步骤1所述的超声分散，是在15～25KHz的频率下超声25～35分钟。
步骤4所述的超声分散，是在15～25KHz的频率下超声15～25分钟。
本发明的优点在于可以直接用于镁合金板带材轧制生产过程。该乳化液具有油膜强度高、摩擦系数小、稳定性好、板面清洁性好等良好的润滑特性，不仅利用了乳化液中油份对轧辊起到隔绝保温作用，而且还利用了水分清洗掉轧制过程中产生的大量镁粉，从而有效地改善了产品表面质量，降低了轧制能耗，而且环保无毒，对环境污染小，同时循环使用后，大大降低了企业生产成本。
