背景技术
随着社会的进步,高新技术在生活中的比例越来越高,特别是航空航天以及电子科技的蓬勃发展,对润滑脂行业提出了新的要求,这个要求主要体现在润滑脂在高真空下的蒸发度要小。
目前,我们所熟知的真空环境有航天航空飞行器、液晶显示器的生产以及一些高精密电子元件等,应用于高真空环境的润滑脂全部都是进口的,经过研究分析,这些润滑脂中使用的基本原材料在市场上是可以购买到的,但是用这些基本材料做的脂在真空环境下无法达到实际使用要求,由此推断这些原材料是经过特殊处理的,特别是基础油,因此需要寻找一种能解决基础油本身在高温下蒸发的问题。
发明内容
有鉴于此,本发明提供本发明提供了一种极低挥发性PAO(合成烃)润滑脂,该润滑脂的应用温度低于180℃,通常在-40℃~150℃,在高真空、高温时的蒸发性极低,可以达到进口产品的水平。
本发明的技术方案如下:
一种极低挥发性PAO润滑脂,采用如下重量百分比的原料制备而成:经精馏的低粘度聚ɑ-烯烃55%~80%,聚四氟乙烯微粉19.5%~44%,二烷基二苯胺0.5%~1%。
优选的,所述低粘度聚ɑ-烯烃为1~3中不同粘度的PAO组成,100℃运动粘度,10~40mm2/s。
优选的,所述聚四氟乙烯微粉由1~3不同种类的PTFE组成,粒径范围:2微米~10微米。
本发明还一种极低挥发性PAO润滑脂的制备方法,包括如下步骤:
步骤1):将1~3中不同粘度的PAO与二烷基二苯胺按照配比均匀混合,混合后备用;
步骤2):将步骤1)得到的基础油进行精馏处理;
步骤3):将蒸馏出的重组分取出,按照配比和PTFE一起加入至搅拌釜中搅拌均匀,搅拌速度35~45rpm;
步骤4):目测搅拌均匀后,研磨一遍后混合均匀再研磨两次,用脂桶装好,一分钟出脂量为1kg±0.5kg。
本发明的有益效果是:采用的组成简单,工艺简单,有效的降低了成本以及其生产的润滑脂可以达到应用要求。
