Description

一种添加改性壳低聚糖表面活性剂的植酸硅烷保护型乳化切 削液
技术领域
本发明涉及金属加工助剂技术领域，尤其涉及一种添加改性壳低聚糖表面活性剂的植酸硅烷保护型乳化切削液。
背景技术
随着现代机加工向高速、精密方向的快速发展，要求金属加工切削液具有更加优良的润滑、冷却、清洗和防锈功能，以便获得理想的加工表面。另外，随着人们环保意识的增强，对切削液环保性能也提出了更高的要求。传统的矿物润滑油的润滑、防锈性能优越，但冷却、清洗性能差，且对环境有影响；而传统的乳化液和水基切削液的冷却、清洗性能优良，且对环境影响小，但润滑、防锈性能较差。因此，研制一种既具有油性切削液优异的润滑和防锈性能，同时又具有水基切削液优异的冷却和清洗性能的环保型切削液具有重要的实际意义。
《十二酸二乙醇酰胺硼酸酯的制备及其在半合成切削液中的应用》一文中采用十二酸、二乙醇胺和硼酸为原料制备十二酸二乙醇酰胺硼酸酯，然后将该硼酸酯加入基础油中制备一种半合成切削液，具有良好的极压抗磨性能、润滑性、耐腐蚀性。但是由于文章中并没有指出具体使用哪一种基础油，为了增强环保性能，需要采用润滑性、水解稳定、可生物降解的基础油作为矿物油的替代，而且为了进一步满足金属加工助剂的发展，需要对产品的防腐蚀性能以及其他附加性能进行进一步增强，使其发展为集防腐、润滑、清洗、冷却为一体的金属加工切削液。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种添加改性壳低聚糖表面活性剂的植酸硅烷保护型乳化切削液。
本发明是通过以下技术方案实现的：
一种添加改性壳低聚糖表面活性剂的植酸硅烷保护型乳化切削液，由下列重量份的原料制备制成：多元醇酯50-54、十二酸二乙醇酰胺18-19、硼酸3-3.3、对甲苯磺酸0.7-0.8、石油醚适量、甲基三乙氧基硅烷0.4-0.5、植酸5-5.5、去离子水适量、无水乙醇适量、溴酸钠0.2-0.25、蓖麻油聚氧乙烯脂肪酸酯30-34、石油磺酸钠8-8.5、山梨醇单油酸酯3-4、油酸钠1-1.5、脱氢枞酸缩水甘油酯10-11.5、壳低聚糖2-2.2、N-甲基吡咯烷酮10-11、丙酮适量。
所述一种添加改性壳低聚糖表面活性剂的植酸硅烷保护型乳化切削液，由以下具体步骤制成：
（1）将十二酸二乙醇酰胺、硼酸混合均匀，加入对甲苯磺酸以及总量1.5-2倍量的石油醚，通入氮气保护，加热至120-125℃，搅拌反应5-6小时后结束反应，将反应产物降温至90-110℃进行旋转蒸发，蒸发掉石油醚后得到十二酸二乙醇酰胺硼酸酯；
（2）将植酸溶于5-6倍量的去离子水中，搅拌均匀后放入溶于10-12倍量无水乙醇的甲基三乙氧基硅烷，水浴加热至75-80℃，以300-400转/分的速度搅拌2.5-3小时，得到植酸硅烷杂化溶胶，在800-1000转/分的速度搅拌下加入溴酸钠，继续搅拌10-15分钟后得到溴酸钠掺杂的植酸硅烷溶胶；
（3）将壳低聚糖加入N-甲基吡咯烷酮中，搅拌并分散均匀，缓慢加热至50-55℃，再加入脱氢枞酸缩水甘油酯，继续搅拌反应5-6小时后冷却，加入总量1.5-2倍量的丙酮沉淀，抽滤，得到沉淀物；将沉淀物用丙酮洗涤2-3次后抽滤，将抽滤后的固体置于真空冷冻干燥机中干燥，得到改性壳低聚糖表面活性剂；
（4）将步骤（1）得到的产物与多元醇酯混合均匀后加入总量1.8-2倍量的去离子水，搅拌均匀后加入步骤（2）步骤（3）得到的产物，以400-500转/分的速度搅拌10-15分钟后加入其余剩余成分，继续搅拌10-12分钟后即得。
本发明的优点是：本发明通过十二酸二乙醇酰胺与硼酸等成分进行反应生成十二酸二乙醇酰胺硼酸酯，添加到产品的制备中，具有良好的防锈、抗氧化性能；通过将甲基三乙氧基硅烷与植酸进行脱水缩合反应，将多个植酸分子聚集在一起形成了这个连续多孔的三维结构，配合溴酸钠的添加，成膜过程中溴酸钠迅速地把金属表面氧化，使得植酸更容易在金属表面吸附、螯合成膜，配合十二酸乙醇酰胺硼酸酯的添加，通过切削乳化作用能够在金属表面形成致密的保护膜，具有良好的抗磨、缓蚀的效果。
本发明还通过脱氢枞酸缩水甘油酯与壳低聚糖进行反应生成改性壳低聚糖表面活性剂添加到切削液的制备中，具有良好的界面吸附能力，具有优异的乳化、成膜性能；本发明半合成切削液产品为水性产品，抗磨减摩性能优异、润滑冷却性能好，同时在金属切割加工的过程中，能够在金属表面形成一层保护膜，具有良好的缓蚀功效。
