Description

一种汽车遮阳板卡簧润滑脂
技术领域
本发明涉及润滑剂领域,具体来说,涉及一种汽车遮阳板卡簧润滑脂及其制备方法。
背景技术
汽车遮阳板是为了遮挡在汽车行驶中射入驾驶员或副驾驶乘客眼睛中炫目光面设置的,其主要功能是通过翻转本体达到正面和侧面遮阳的目的。此功能是通过轴和本体中的卡簧,轴和轴座间配合来实现的,并能使遮阳板在翻转过程中任意位置停留,以调整遮阳的角度,并且具有自动回复贴顶的功能。卡簧对遮阳板功能的实现起到了很大的作用。
现代汽车遮阳板转轴安装时所采用的卡簧是整体式的。这种卡簧结构复杂,工艺要求高。当转轴与卡簧安装在一起时,转轴与卡簧间的精度不易保证,当遮阳板在贴顶棚的姿态下,容易随车的颠簸产生噪音,同时在遮阳板翻转过程中,卡簧导致操作力不均匀,遮阳析在翻转时易晃动、脱落。为解决上述问题,采用润滑脂对卡簧与转轴进行有效润滑就显得特别重要。
发明内容
本发明的目的是提供一种高低温性能良好、润滑抗磨性优良、耐久性极佳的汽车遮阳板卡簧润滑脂,保证遮阳板的终身润滑要求。
本发明涉及的一种汽车遮阳板卡簧润滑脂,以其总重量为基准,包含以下组分:40~60%重量%的合成烃基础油、1~3重量%的锂皂稠化剂、15~30重量%的三聚氰胺氰尿酸盐、15~25%重量的氮化硼及0.2~0.5重量%的抗氧剂。
所述合成烃基础油为聚α-烯烃。在润滑油领域,聚α-烯烃是一种合成基础油,简称PAO,具有优良的高低温性能,是配制高档、专用润滑剂较为理想的基础油。
进一步地,所述聚α-烯烃基础油100℃运动粘度为8~50㎜²/s,包括但不限于PAO9、PAO 10、PAO 15、PAO 25、PAO 40,例如可采购自美国雪佛龙-菲利普斯化工公司(ChevronPhillips Chemical Company)。以上PAO加数字表示方式是基础油领域较通用的命名法,后面数字由基础油的100℃运动粘度大小决定。在本发明所述卡簧润滑脂实施例中,可以采用一种PAO型号或多种型号的混合物。
进一步地,所述锂皂稠化剂为12-羟基硬脂酸锂或硬脂酸锂中的一种或两种的混合物。
进一步地,所述三聚氰胺氰尿酸盐(简称MCA)为市售产品,粒径(D50)2μm。
进一步地,所述氮化硼为市售六方氮化硼粉,BN含量≥98%,粒度(D50)0.5~3.0μm。
进一步地,所述抗氧剂为2,6-二叔丁基对甲酚(代号T501)或二异辛基二苯胺中的一种或两种的混合物。
本发明的另一方面,还涉及上述卡簧润滑脂的制备方法。该制备工艺包括以下步骤:
a.将合成烃基础油与锂皂稠化剂在搅拌、加热条件下升温至210±5℃,恒温搅拌10分钟;
b.加入三聚氰胺氰尿酸盐、氮化硼及抗氧剂,在180±5℃下恒温搅拌120分钟;
c.出料,降温至100℃以下,在三辊磨上研磨三遍。
