Description

一种高性能复合磺酸钙基润滑脂及其制备方法
技术领域
本发明涉及润滑油添加剂领域，尤其涉及一种高性能复合磺酸钙基润滑脂及其制备方法。
背景技术
磺酸钙常用作润滑油的清洁剂和防锈剂，磺酸钙基润滑脂是以新型高碱值磺酸钙皂、脂肪酸钙皂及其他皂复合，稠化高粘度精制矿物润滑油，并添加高效能复合添加剂而制成，常用于钢铁冶金行业的设备润滑。
虽然磺酸钙基润滑脂滴点较高，但其在高温下稠度明显变软，在某些高温润滑部位易导致流失和甩油，低温条件下，特别是-30℃以下时，润滑脂将变得非常粘,造成输送困难。生产过程中醇类、醚类等转化剂的大量使用也会对环境造成污染，为了治理污染也会增加了生产成本。
发明内容
本发明的目的提供一种高性能复合磺酸钙基润滑脂及其制备方法，解决上述现有技术问题中的一个或者多个。
根据本发明的一个方面，提供一种高性能复合磺酸钙基润滑脂，按重量份包括聚α烯烃合成基础油35-45份、高碱值磺酸钙15-25份、液体转化剂3-5份、聚环氧乙烷2-3份、12-羟基脂肪酸5-7份、樟脑1-3份、苯基-α-萘胺二烷基二苯胺0.5-1份。
在一些实施方式中：基础油包括60％的聚α烯烃，其100℃粘度为4mm/S，40％的邻苯二甲酸二辛酯。
在一些实施方式中：碱值磺酸钙，其超高碱值为400mgKOH/g。
在一些实施方式中：液体转化剂采用乙酸、乙醇、异丙醇、水、碳11-碳22的羟基脂肪酸中的一种或他们的混合物与二氧化碳气体组成。
本发明还提供了上述的高性能复合磺酸钙基润滑脂的制备方法，包括以下步骤:
将聚α烯烃合成基础油、高碱性磺酸钙、液体转化剂混合搅拌并升温，升温至65℃，恒温搅拌30min后通入二氧化碳(流量为5ml/min)60min，稠化后加入12-羟基脂肪酸、聚环氧乙烷、樟脑升温至130℃，复合皂化1h，升温至150℃脱水1.5h，加入苯基-α-萘胺二烷基二苯胺后升温至210℃炼制，保持10min降温至110℃均化脱气成品。
本发明具有优良的耐高温性、耐低温性、良好的机械安定性、优异的极压抗磨性，生产过程中减少了醇类、醚类等转化剂的使用，降低了环境污染，提升了牛顿体高碱值磺酸钙转化成非牛顿体磺酸钙的效率，并且转化较为彻底，使得生产工艺更为简单。
