Abstract
本发明提供了一种氟改性硼酸酯及其制备方法和包含该氟改性硼酸酯的制动液，所述氟改性硼酸酯的结构式如下所示，其中，R1为氟取代的C1‑C5烷基；R2为氢或C1‑C5烷基；n＝2～8。与现有技术相比，本发明通过氟改性硼酸酯的制备，将含氟材料疏水性的优点融入到硼酸酯中，较非氟的硼酸酯相比具有更高的疏水性。本发明以氟代醇和环氧烷烃为原料，通过聚合、酯化制备氟改性硼酸酯的步骤，具有反应后处理简单、产率高、操作简单、便于分离等优点。另外，本发明提供了两种氟改性硼酸酯型制动液，其具有高的干湿平衡回流沸点和良好的高低温运动粘度。
Description
技术领域
本发明属于制动液技术领域，特别提供了一种氟改性硼酸酯及其制备方法和包含该氟改性硼酸酯的制动液。
背景技术
硼酸酯是一个结构独特、性能优良的无机酸酯类化合物。其自身和衍生物可以应用在众多领域中，例如：润滑油添加剂、偶联剂、表面活性剂等。在汽车制动液领域，硼酸酯制动液也存在诸多优势，中国专利CN107573998A一种以三乙二醇甲醚硼酸酯为基础液复配而成DOT6硼酸酯型制动液。它具有良好的高低温性能，又具有憎水性，对钢、黄铜、铜、铸铁、铝等金属无腐蚀性，对橡胶不溶胀，受温度变化影响小。然而，现有的研究仍在致力于提升硼酸酯型制动液的平衡回流沸点和低温运动粘度等主要性能，对其疏水性能的关注不足。硼酸酯遇到少量水时，虽然能够通过自身的水解具备一定的抗水性，但若长时间暴露在湿度较大的环境中时，大量硼酸酯的水解产物—硼酸会以固体的形式从制动液中析出，而硼酸不仅会腐蚀金属，还会对制动液的性能有严重影响(陶佃彬,广东化工,2021,10,99)。随着中国汽车市场的快速发展，对高端制动液的需求也越发紧迫，因此，如何在保证制动液主要性能的同时进一步提升其疏水性能就成为了亟待解决的问题。
含氟材料由于其具高疏水性，高的热稳定性，低折射率以及良好的生物相容性等等在多个领域都得到了广泛的应用。利用氟改性提升材料的疏水性能已有诸多报道，例如，在经典的疏水材料聚丙烯中空纤维膜中，通过全氟硅烷的加入使得其水接触角由73°增加到97°(Zhihao Xu,Desalination,2017,414,10)，疏水能力明显增强；在疏水性涂料的配方中，提升十三氟辛基三乙氧基硅烷的加入比例，水接触角由100°增加到110°(MohammadReza Heshmati,Polymer Bulletin,2022,79,9427)；此外，在热敏性材料聚(N-异丙烯酰胺)中(Jae Min Bak,Polym.Chem.,2013,4,2219)，通过控制分子末端的甲基上氟原子的个数，达到调节材料疏水能力的目的。
但是，目前并没有含氟制动液的相关研究。

其中，R1、R2和n同权利要求1或2所述。
优选的，步骤(1)中，所述的碱为氢氧化钠、氢氧化钾、甲醇钠、碳酸钠、碳酸氢钠、碳酸氢钾或三乙胺中的一种或几种。
优选的，步骤(1)中，所述聚合反应时间为2～10h，聚合温度为120～240℃，氟代醇与环氧烷烃的摩尔比为1:2～10，碱用量为氟代醇摩尔当量的2.5％～20％，聚合压力为0.2～6MPa。
优选的，步骤(2)中，所述氟改性聚醇醚与硼酸发生酯化反应，制备氟改性链状硼酸酯的反应中，酯化反应时间为3～15h，酯化反应温度为100～200℃，硼酸与氟改性硼酸酯的摩尔比为1:3～6。
优选的，步骤(2)中，所述氟改性聚醇醚与六元环状硼酸发生酯化反应，制备氟改性环状硼酸酯的反应中，酯化反应时间为3～15h，酯化反应温度为100～200℃，硼酸与氟改性硼酸酯的摩尔比为1:1～5。
本发明还提供了一种制动液，包含所述的氟改性硼酸酯。
优选的，所述制动液包含氟改性硼酸酯、稀释剂和制动液添加剂。
进一步优选的，所述稀释剂为三乙二醇单甲醚、三乙二醇单乙醚、三乙二醇单丁醚中的一种或几种；所述制动液添加剂为pH调节剂、橡胶溶胀剂、抗氧剂、防锈剂、水解稳定剂中的一种或几种。
有益效果：与现有技术相比，本发明具有如下优势：
(1)本发明通过聚合、酯化的步骤制备氟改性硼酸酯的步骤，具有反应后处理简单、反应条件温和、便于分离等优点；
(2)在硼酸酯中引入含氟基团，该化合物由于在硼酸酯上引入了氟，使其具有更高的抗水性；
(3)提供了两种氟改性硼酸酯型制动液，其具有高的干湿平衡回流沸点和良好的高低温运动粘度，性能可以达到DOT6标准。
因此，本发明提供了一种全新的性能能够达到DOT6标准的制动液，并且进一步提升了疏水性能。
